Balance Hormones with Collagen Hydrolysate and Gelatin

collagen hydrolysate can help balance hormones

Collagen Hydrolysate: A gelatin supplement

Who needs Botox when you’ve got bone broth? (Ha ha, real food joke.) Homemade bone broth, as many real-foodies know, provides a rich source of collagen, a component that adds luminosity and plumpness to the skin.

Both collagen hydrolysate and gelatin comes from cooking the bones, hides and hooves from animals. Dietary sources of quality gelatin have all but disappeared from the modern diet, although past generations widely consumed gelatin-rich broths, soups, headcheese, calves foot jelly, sauces and aspics. These sources of gelatin not only tasted delicious, it boosted the nutritional profile of the meal.

What is collagen hydrolysate?

Collagen hydrolysate is a dietary supplement. It is essentially gelatin and carries all the benefits of gelatin, however it is processed in a way that it dissolve into hot and cold liquids without gelling and is more quickly absorbed by the body. 

UPDATE: Previously in this post, I recommended Great Lakes Gelatin and Great Lakes Collagen Hydrolysate. Now, I recommend Vital Proteins Collagen Peptides and Collagen Protein (Gelatin). I switched my recommended brand because I think Vital Proteins is a higher quality product with better packaging. Plus, they offer free shipping on all their orders and I love their customer service. 

So, just to clarify, collagen hydrolysate is interchangeable with Vital Proteins Collagen Peptides.

You can purchase Vital Proteins Collagen Peptides here (free shipping on all orders).

Collagen hydrolysate vs. gelatin

Collagen hydrolysate and gelatin both start from the same ingredient: collagen from beef (or pork, for the non-kosher gelatin option) hides. As a result, these two products share the same amino acid profiles. The primary difference is that collagen hydrolysate is more easily assimilable due to the hydrolyzing step and it does not gel. On the other hand, gelatin can be used to make jello and puddings. 

When I use the term “gelatin” and “collagen hydrolysate,” remember that these are basically interchangeable in regards to the health properties.

Collagen hydrolysate and gelatin help balance hormones

Of the amino acids in collagen hydrolysate and gelatin, 35% is glycine and 21% is proline and hydroproline. Also important, collagen hydrolysate/gelatin completely lacks the amino acid tryptophan. The high percentage of glycine and proline, as well as the lack of tryptophan, help balance the ingestion of large amounts of tryptophan and cysteine present in muscle meats. The equilibrium of amino acids play a large role in metabolic rate, thyroid function and hormone production. 

Dr. Ray Peat, a hormonal researcher in the field of nutrition and metabolism, describes why muscle meats when consumed without gelatin can increase stress hormones and decrease thyroid hormones

Gelatin is a protein which contains no tryptophan, and only small amounts of cysteine, methionine, and histidine. Using gelatin as a major dietary protein is an easy way to restrict the amino acids that are associated with many of the problems of aging.[…]

When only the muscle meats are eaten, the amino acid balance entering our blood stream is the same as that produced by extreme stress, when cortisol excess causes our muscles to be broken down to provide energy and material for repair. The formation of serotonin is increased by the excess tryptophan in muscle, and serotonin stimulates the formation of more cortisol, while the tryptophan itself, along with the excess muscle-derived cysteine, suppresses the thyroid function.

[…]If a person eats a large serving of meat, it’s probably helpful to have 5 or 10 grams of gelatin at approximately the same time, so that the amino acids enter the blood stream in balance. (Read more)

Note: a level tablespoon of collagen hydrolysate provides 7 grams of gelatin.

The point here, of course, is that amino acids consumed out of balance are not conducive to health. Does that make tryptophan bad? No. Does is make serotonin bad? Nope. Does it make cortisol bad? No again. The trouble arises when these elements are out of proportions.

By helping to balance the tryptophan, gelatin supports healthy thyroid function and reduces the metabolic stress of increased cortisol. Thyroid and metabolism go hand-in-hand, so gelatin may actually increase metabolism by improving thyroid function.

Ray Peat also explains the anti-stress properties of the glycine found in gelatin:

A generous supply of glycine/gelatin, against a balanced background of amino acids, has a great variety of antistress actions. Glycine is recognized as an “inhibitory” neurotransmitter, and promotes natural sleep. Used as a supplement, it has helped to promote recovery from strokes and seizures, and to improve learning and memory. But in every type of cell, it apparently has the same kind of quieting, protective antistress action. (Read more)

Improve digestion with gelatin and collagen hydrolysate

Dr. Pottenger, another researcher who offered extremely valuable research in the field of nutrition, praised bone broth because it provides a source of hydrophilic colloids in the form of gelatin. Raw foods tend to be hydrophilic – water-loving – and blend with digestive juices for efficient digestion.

Cooking food, however, often creates hydrophobic colloids and can repel digestive juice in the stomach. Because collagen hydrolysate/gelatin remains hydrophilic even when heated, it aids digestion of cooked food. 

Further, the glycine in gelatin stimulates stomach acid production and thereby improves digestion and nutrient assimilation. Low stomach acid is a chronic problem that leads to a cascade of symptoms in the entire body, so increasing stomach acid often alleviates a host of issues. (Source – Weston Price Foundation’s Broth is Beautiful article)

Because poor digestion underlies all hormonal imbalances, improving stomach acidify and nutrient assimilation supports the roots of hormone balance.

How to take collagen hydrolysate and gelatin

Ideally, consume a source of gelatin with each meal. This could be a cup of homemade bone broth, some homemade jello bites or a tablespoon of collagen hydrolysate stirred into a smoothie or beverage.

Remember, the collagen hydrolysate/collagen peptides do not gel in liquid, while the Vital Proteins collagen protein can be used to make jello and gummies.

      Do you mean the same way as the collagen hydrolysate – mixed into liquids/smoothies? The hydrolysate will dissolve into hot and cold liquids and doesn’t leave a “slimy” texture that results when you mix the gelatin into hot beverages. I also find that the gelatin leaves a slightly flavor while the hydrolysate is almost flavorless. The gelatin will not dissolve well into cold beverages and can get lumpy when mixed into hot beverages if not mixed well.

      • BP says

        Hello! Thank you for your great article! I had a question about the “nightcap” you make with coconut milk, collagen hydrolysate, and honey. In Food Combining, it is a cardinal rule to not mix sugars with protein (i.e. that includes bread with meat) as they have different digestion processes and will cause indigestion. Do you have a different philosophy that guides your choice in using fats, sugars, and proteins in combination?

        Many thanks! Loved the article!

  1. JessicaR says

    Is it possible for gelatin to actually imbalance hormones rather than balance them? I have found that since taking Great Lakes Gelatin (2 to 3 tsp per day), my cycle runs much longer than it used to (five to six weeks instead of four).

    • zosia says

      you should also look at the overall picture and see what else is going on in your life.
      Have you changed your routine in some way? Are you more stressed than usual? Less stressed?
      Did you add something else to the diet? …or cut something out? etc. etc.

    • Kristy says

      I’d love to be in your shoes since my cycle has gone the opposite way the last several years and I’m now recovering from iron anemia. Hoping gelatin helps. :-)

    • amber says

      I also noticed an imbalance. My cycle got shorter (not complaining except it was so short and light I kept thinking I was missing it) and my skin is breaking out baaadly. I’m 31 and have a pizza face like a teenager. It was the only real change I had made to my diet so I have cut it out for a week and my flow is back and my skin seems to be clearing up.

      • Norma says

        That exact thing happened to me, but I just take the proeins like for 4 days, and my face started to look like a pizza as yoy say hahah mostly in my cheen, how are you doing now? Did you stop taking the powder and your face looks better?

      • MC says

        Wonder if it could be a detox affect? You know how sometimes things have to get worse before it gets better? Just my input

      • Shelley says

        I wonder if the acne could be because of a histamine intolerance. I know this is supposed to have low histamine but any preserved meat protein is suspect.

  2. zosia says

    I understand that “grass-fed” changes (or rather ENHANCES) the fat and nutrient profile of beef (the actual meat); however, since beef gelatin is an isolated product (which does not include nutrients (other than amino acids) and fat), shouldn’t it be that grass-fed in regards to gelatin is of no importance?

      • zosia says

        While I agree wholeheartedly with you, you still didn’t really answer my question.
        I still don’t really understand what fundamental damage I would be doing if I used non grass-fed beef gelatin…

        • Jessi says

          If you consume non grass-fed gelatin then that means it was made from cow’s that were conventionally raised, i.e. pumped full of antibiotics and hormones. I have no clue how much of a difference that makes in the gelatin, but I have to assume you get some residual contamination.

          • Mary says

            Is it an assumption that grass fed means no added antibodies or hormones? I see no wording on Vital Proteins packaging that states animals were not treated with antibotics nor were they given hormones.

            • says

              We do test our products for hormones and antibiotics and our products are free of hormones (rBGH which is listed on our container) as well as other substances such as pesticides and other chemicals such as ractopamine, glyphosphates, and other pesticides.

  3. karen says

    i have to get some of this one. i have the red one and make “gummies” with them. i would love to read a post on your daily routine :)

  4. Bobbie says

    Hi Lauren! You mentioned adding the collagen hydrolysate to your morning smoothie. Would you share your ideas for morning smoothies with us?? Thanks for sharing!!

  5. says

    Hi-Love your blog posts! Question about the collagen you mention in this article…can I put it in my bulletproof coffee? Also is it beneficial to bake with in the same way you use gelatin to bake with?

  6. says

    love this! even more reasons why we love taking our gelatin, we take both forms of Great lakes a few tablespoons a day. We love making marshmallows :) We have noticed great improvements in our skin and health once we started taking it almost a year ago.

    • Deb says

      Doing the gelatin for my 13 year old daughter. Do you have a great marshmallow recipe that you would share. Best to you both,


  7. says

    Thanks for the great info! I’ve been taking collagen hydrolysate for a few weeks mixed into my morning dandy blend. I’ve been taking it for gut health but I didn’t realise the effect on hormones. I missed it a few days last week and had a couple of extremely emotional days – I wonder if that might explain my hormones feeling so out of whack.

  8. Fabiola says

    Thank you so much for explaining the differences so clearly for us! I had purchased both and couldn’t figure out why they were different and where to incorporate them.

  9. Helen says


    I am 24 years old, and had gotten diagnosed with premature ovarian failure 3 years ago (in other words premature menopause) The doctors had me on aritifical hormones, and I have decided that I want to take control of my life and body and learn how to balance my hormones naturally. Is there anything you would recommend I do?

    • Anya says

      It saddens me to read about your diagnosis but rest assured, there is so much you can do to reverse premature ovarian failure. I too was diagnosed with that few years ago. I was devastated as I was in my late 20s. I have since adopted a very WAPF/Paleo/GAPS diet and am slowly recovering. I’ve been getting my periods back (so happy to see Aunt Flo again!!). I focused on consuming lots of healthy fats: (ghee, butter (grass-fed of course), coconut oil, raw cheese & milk), fermented foods (sauerkraut, kefir) and herbal teas (nettle, red clover, vitex berries). I’ve also cut out all the toxic household cleaners and toiletries. I make everything myself now: from laundry detergent to chapstick. It is possible to heal – our bodies are amazing machines – you just have to supply the right materials!! Blessings to you Helen and thanks Lauren for all your work. Love your blog.

  10. Martha says

    Hi Lauren, I just discovered your site from Weed’em and Reep. I love all of your amazing recipes and using food to heal, I am a big believer! I wanted to give you some information for your digestive issues on the worlds #1 Aloe. My really good friend Missi had the exact same thing as you and like you had tried all of the medicines and nothing was working. She also used food and nutrition to help but once she started taking this ultimate aloe- she hasn’t had a flair up in 6 years! I started taking it along with the Isotonix daily essentials vitamins back in November of 2013 and have felt amazing. I, luckily, didn’t have any major issues but have noticed PMS cramps disappear (thanks to the calcium) my skin tone improve and just overall more energy. If you would like to try some I would love to order some for you or talk in more detail. Please feel free to look into the product and contact me if you’re interested! Hope you have a blessed day.- Martha

  11. Amanda says

    Hi! I’ve been following you on Pinterest for a while now and decided to try the collagen hydrosolate because I know how important amino acids are and to help balance my hormones. I’ve been taking them for almost a month now and my skin is breaking out really bad. I NEVER have break outs and rarely get pimples so I’m concerned it’s from the collagen. Please let me know if you have any insight!!

    • Amy says

      Hi Amanda. I just recently starting taking gelatin too and it seems my face has blown up with pimples, mainly on my chin, since taking it. Did you ever get to the bottom of this…I seen that no one replied to you.

  12. Lyn howett says

    Is it o.k. To take porcine gelatin in the orange can! It is not the beef one it is the pork one in the grat lakes unflavored gelatin collagen joint care?

  13. Vanessa says

    Hi Lauren,

    Been following your posts for a while now. I love how accessible you make the information :-)

    The Ray Peat reference reminds me very much of something else I read somewhere, I think perhaps from the recent PaleoCon online webinar series or mentioned by Stefani Ruper, about how exercise doesn’t just effect the body globally, like to decrease insulin resistance, but it also works on a more specific level in the cells to enhance the cells ability to receive parts for energy. I suppose this has to do with mitochondria.

    Maybe this plays into the effectiveness of Whole Body Vibration (WBV) therapy (Dave Asprey at has an (expensive!) product that serves this purpose, and I’m sure then other extra info on it). Not to mention the added benefit of moving fluids in the body, like a rebounder.

    Keep up the great work!

  14. Laura says

    Have you ever tried to add collagen hydrolysate to homemade ghee?
    The idea just occurred to me when I read what you wrote about it probably needing to be balanced with carb and fat. Not sure what could be the carb to add it to though.

  15. Jackie says

    I believe in the benefits of adding gelatin to the diet. I attempted to do this using the Great Lakes brand and developed bloating. I tried decreasing to only a teaspoon a day and still experience the bloating, although not as significantly. Is it uncommon to experience “side effects” when initially introducing gelatin to the body?

    Thank you so much for the input.

    • says

      Collagen Protein Powder-I first thought I had found the Lord’s greatest miracle. Skin-wow! wrinkles disappear, joint pain disappears, sleep is improved. Then the bloating started. Water retention-extreme. Gained 4 pounds in a week. I was freaking out cause I was barely eating-(it cuts your appetite)…but my face was so puffed up I barely looked like myself. I didnt know what was causing this, until I finally decided to try a day with no collagen protein….by the end of the first day, my pants were getting looser and my face had started returning to its normal size/shape. Beware. This stuff is amazing…but it comes at a price and for me the price is too high….I might try one spoon once a week, maybe thats plenty. BEWARE! And if you start gaining weight for “no reason”, this is why…… :-(

        thanks for your comment, this is exactly what is happening to me. I love this stuff and every aspect EXCEPT even though I hardly eat at all because I have no appetite I have gained 4 pounds in the last couple of weeks and couldn’t figure out why, also could not find ANY research or explanation anywhere until I read your comment.

        • Penny says

          I have read in research papers, that the collagen increases LEAN Muscle tissue (a good thing,) so that is probably some of your weight gain.

  16. Ginger Coleen says

    Hi Lauren – I started taking the Collagen about 3 months ago based on your recommendation. I had gum problems all my life and a tooth that was getting infected off and on because my gum had pulled away and down on the backside of it allowing food and who knows what to go down under the tooth. At some point I noticed that my gum had become firm and the tooth was not as loose as it had been and, of course, no more infections. Then I read on that it also helps to heal gum disease. Here is a link but I’m not sure it was on that page: I’ve checked the rest of my gums now and I’d bet that any dentist would no longer claim I had gingivitis as they have most of my life. My gums are firm plump and just the right shade of pinkish/red.

    This is really a potent healing remedy for so many things. I will keep taking it and thank you so much for helping me and so many others.

  17. Claudia Lorena Balboa de Quinto} says

    Thanks Laureen! I’m translating some of these points to Spanish for my friends. If someone here needs this information in Spanish, feel free to ask.

        I’m taking for about 2 days The Great Lakes Collagen Hidrolysate,
        But I’m feeling some weir, some dizzy, Also some Muscle streching sensación.
        It’s normal To feel this way?

  18. Olga says

    Lauren – do you drink morning smoothie with an egg yolk while on AIP? Or you have your own version of autoimmune protocol based on what your body tolerates?

  19. Karissa says

    I started taking Now Foods Beef Gelatin 550mg Hydrolyzed Capsules a week ago to see if it would help with my health. I have some form of connective tissue/collagen disorder that my rheumatologist has been unable to classify. My toes have an odd purple hue and swell very easily. My right fingers swell up, itch and burn all winter, every winter. It is not known what this is and why my left fingers stay normal. I had an ice water test and did not fit the criteria for Raynaud’s syndrome although it is similar. I had my amygdala and hippocampus removed 4 years ago due to a cancerous tumor. I had epilepsy prior to the surgery but had not experienced any seizures afterward. I wanted to try beef gelatin to see if it would help with my fingers and toes, help me with handling stress (I am unable to handle even the slightest bit of stress which I assume is due to the removal of the stress-control areas of the brain), give me energy (I am almost always tired), help with memory and mood, and help with my stomach issues. I have been battling candida and leaky gut syndrome since being on steroids for a brief period after the surgery.
    Since taking the gelatin, I have had a painful, bloated stomach that makes odd gurgling noises. My fingers and toes have swelled up a little. I have fallen asleep quickly and sleep through the night, yet I wake up feeling exhausted. My brain feels swollen. I notice that I have puffy eyes and the small bald spot on my head from the surgery has gone from an indent to swollen. Worst of all, I have the feeling like a seizure may come at any second. I haven’t had this feeling for 4 years. It is an odd feeling of dread. Therefore, I will not continue to take the gelatin.
    I am wondering if anyone may know why my body is having the opposite reaction than what other people seem to have. I have read that gelatin is beneficial in recovering from epilepsy, helps to heal the gut and controls inflammation. Why would these issues be worsening for me? This is very frustrating after reading all of the positive information on this.

    • Karissa says

      I should add that a I had catamenial epilepsy, meaning that my seizures worsened around menstruation due to hormonal shifts. At the time of taking beef gelatin, I was not near that part of my cycle.

      • Danae says

        Dear Karissa, I hope your situation has calmed down – it is always a learning curve. I am not a doctor but had for years strange symptoms nobody could ‘define’. However, make sure your ‘leaky gut’ is really healed as this could be the trigger. Anything our body cannot metabolise will cause these strange symptoms – e.g. swelling when the lymph system gets overwhelmed. You might wish to look for a cleansing regime and check out the supplement Glutamine and DGL and or mastic gum to heal your gut. Read up on GAPS (from the principle) and perhaps make a leaky gut test to be save. Once your colon is balanced… healing and shift for the better always happens. God bless.

    • onna says

      your problem may be liver related. please seek out a traditional chinese medicine doctor, that works with herbs as well as with acupunture, and don’t just push pens, or give you a herbal formula that will help eleviate your symptoms. seek one that does only tradtional chinese medicine practices, cupping, moxa, acupunture and nutrition. there are alot of tcm trained doctors who stray from their training, these will not do. also the acupunture and herbal protocol should change with your syptoms. i hope this helps. good luck and god bless.

  20. Steve says

    Karissa, it’s possible you have methylation issues related to a MTHFR mutation (which might also explain some of your health problems). It is my understanding that gelatin (and bone broth) cause problems if you have such a mutation.

  21. Jolaine says

    Love this info! I thought I’d let you know that there is also grass fed/finished collagen available by Bulletproof. It seems to be excellent quality. I’ve tried both.

  22. Marilyn says

    Maybe with more time/research i could find the answer; but, here goes. What about the info that its only possible for the collagen ‘supplement’ to be useful if taken on an empty stomach. What is it about the stomach acids destroying the collagen? How does that pertain to bone broth? vs hydrolyzed collagen? The more I learn the more I realize that I know less…

  23. Gerry says

    Does the collagen hydrolysate contain gluten? I read a list of gluten containing foods published by Dr Perlmutter and “hydrolysate”was listed under a heading of ”might be an ingredient indicating gluten’.

  24. says

    Wow !!!! I Am amazed, I have never heard of gelatine in this way before. I live in Australia and I would love to start trying this to help with my terribly itchy skin, which disrupts my sleep , I have had for 8 years and anything I try is short lived relief. Also now I am in my late 40’s and my hormones and cycle are changing. Can you let me know how to order some please. Thanks Steph

  26. Christy says

    On the can of Great Lakes’ Collagen Hydrolysate (green can) it says that it “promotes rapid re-production of blood cells…” I am in remission from Multiple Myeloma. The doctor says there are still cancer cells in the blood plasma, in the marrow. Will the collagen cause those cells to reproduce?

  27. James Sklar says

    My wife has done research on hydrolysate and it seems to lead to skin break-outs, with women. The areas most affected are the chin and upper back. I’ve taken it too, but I haven’t had any such problems.

    I think women should approach this product carefully.

    • Alex Nielsen says

      Interesting…I’ve been trying to figure out why I suddenly have an acne problem and it does seem to correspond to when I started taking collagen. I’ll have to stop taking it and see if it clears up. I thought it was supposed to be so good for the skin.

  28. Barbara says

    I started taking the Great Lakes green can just days ago. I read enough about it to know to start small so I very been taking a top at night with almond milk honey and nutmeg. But I’ve had a pretty bad headache more on than off since. This is the only change and I’m also very tired and just a little foggy. I’m assuming this means I can’t take it. I’m having hormone and joint pain issues so I really need this to work. Any suggestions! ?!?

    I’ve tried Swanson Vitamins Hydrolyzed Fish Collagen (#SWU759) with very good results. It doesn’t smell fishy and some people that either dislike fish or are allergic to it have done fine. What is your opinion regarding fish collagen compared to beef collagen as far as effectiveness and benefits?

  30. Donna says

    The cattle from Great lakes Gelatin are also grass fed and come from Argentina and Brazil which is controlled by their respective Department of Agriculture. i read on the Vital website that their gelatin product also comes from grass fed cattle in Brazil. So what do you actually think makes the difference between the Great lakes Gelatin and the Vitals? i also get free shipping from the Great lakes when i order through Amazon.

  31. Elke says

    Hi Lauren,
    is there a difference between the Great Lakes gelatin and this Vitals brand? you had a link to the Great Lakes before and now the Vitals.
    Thank you
    and for all your writings =)

  32. Michele says

    Loved the article. I have a very hard time with anything that has any odd consistency. I bought the Great Lakes Gelatin and that was a no go for me. Then I tried the NeoCell Super Collagen (Type 1&3) and still have a problem with the taste and consistency. Is there anything wrong with buying capsules and capping my own? Do these items have to be mixed with liquid before ingesting?


  33. Katie says

    I started taking a tbsp of the great lakes (orange can) beef gelatin a month ago. I also have broken out on my face. My period came 3 days early after taking it for the first 3 days and now my period is 8 days early this month. My period has always been regular before this. It’s kind of freaking me out so I am going to back off of this stuff and see if my periods become regular again. I’m hoping it’s just the gelatin and nothing serious.

  34. Niki says

    Lauren and anyone else, can you help me understand why great lakes (both orange and green cans) caused severe bloat and constipation? I tested it many times. I thought is was supposed to help? I have taken pro its chews no problem but they are over priced in my opinion.
    Any input appreciated!

  35. Gina says

    Thanks for the tip, although I didn’t see the connection to cramps and PMS. All this time, I’ve been treating it with mega doses of CHOCOLATE!

  36. Sharilyn says

    I have recently begun taking 1Tbsp of the Great Lakes gelatin daily. Coincidentally, I have also begun having panic attacks. (I have suffered from anxiety in the past, but it has been managed for some time, as I take 20mg of fluoxetine/Prozac per day).
    My question is: do you know if the gelatin could be also increasing the seratonin production in my body, thus giving me too much seratonin when combined with my meds, hence causing these panic attacks? The first one occured in the middle of the night (which has never happened to me before). My symptoms are excessive sweating (especially hands and feet), extremely rapid heartbeat, light-headedness, fear of passing-out, tingling throughout my entire body (like my body is on fire). Thank you for any information or suggestions!

  37. Linda says

    I also had a side effect from the gelatin so it is true that it is not for everyone. I was 62, very limber, no pain and athletic, ate an organic diet mostly fruits and vegetables with small amounts of eggs, dairy and meats. After taking the gelatin one teaspoon in juice for 10 days I was delighted that my degenerated neck became less lose, but then a few days later my entire body got very stiff making it difficult to get up from a chair and my injuries from my entire life began to have pain. As a chiropractor and nutritionist I believed my lack of pain was due to the high level of minerals from my diet, but why this product caused pain is beyond me. I am guessing it is because the effect was too great and the collagen caused my tissues to harden in some way. I stopped taking it the day the stiffness started. After several months it has lessened somewhat and I only have pain in my left hip, so I am hoping the effects of this product will wear off as my body replaces its cells. . I would warn people to start out very slowly with this product from Great Lakes (collagen joint care) as it is powerful and not natural so a little goes a long way. As a doctor I am aware the body is in a very delicate balance and we must be careful to only add small amounts of anything that is not in the form of food, otherwise, we may cause imbalance and harm to ourself. Anyone have a similar experience? I must mention I have taken regular gelatin as in jello with no problem whatsoever in the past for stronger nails and hair.

  38. Nicole says

    QUESTION- I just started taking gelatin for all the health benefits, but to mainly control my hunger cravings. I started with 1 tbl the first day and moved down to 2teaspoons a day after a week. It’s now my second week And I am finding that my face and lips feel EXTREAMLY TIGHT and they tingle along with my lips being very dry ever since I started taking it. Am I allergic? Should I just cut down and only do 1 teaspoon? Or stop all together?

  39. Tony Dien says

    amazing article, I know first hand the benefits hydrolysed collagen can give. Food is medicine! I switched (on advice from my naturopath) from the Brazilian sourced based products (such as Great Lakes) to the product made by an Australian company. it’s called Peptipro, seems to have a greater bio-availability meaning I got the benefits slightly quicker than when I used Great Lakes.

    I must mention I used the hydrolysed collagen to treat my torn shoulder, it’s truly amazing how much it’s helped, without a single injection or any surgery as was recommended.

    Vital Choices has better packaging?! I will stick with Great Lakes, thank you. No endocrine-disrupting plastic containers for me. Food contains phthalates as a result of being packaged in plastic. Also, plastic can’t truly be recycled, only down-cycled. Practically every molecule of plastic ever produced is still in the environment, and a lot of it is floating in the Pacific ocean, killing seabirds and aquatic animals.

    I have been taking the Great Lakes Collagen Hydrolysate for 5-6 days now, 1-2 TBS per day. The last two days I’ve felt completely bloated and without appetite. I see several others have had this reaction. Might this effect normalize after the body gets used to the supplement? Anyone have this experience?

    I am 38 year old female. I have been using the green can of Great Lakes Collagen 2 Tbsp. 2x per day .. 2 Tbsp. in my coffee in the morning and 2Tbsp. mixed in tea or tap water at night. I have been using it now for 5 days consistently. I have been drinking more water than normal because I have read that people tend to bloat from this product. I have not noticed any bloating. I have also had a sore shoulder for the last 2-3 months, maybe a pulled muscle or pulled rotator cuff from water skiing this summer. Today I noticed I was able to reach further than I have been able to in 2-3 months. I do believe it’s the collagen helping! I will continue using this protein in hopes that my hair will grow faster and also for the anti-aging benefits. I have read a lot of great reviews on this product, so thought I would try it, too!

    Im about a year late here, but I figured I’d chime in! The onset of acne has been brought up several times in this thread but I don’t think anyone with a scientific/nutritional background has answered the questions about its correlation to collagen supplementation..

    I started taking a similar kind of organic grassfed collagen about a week and a half ago and within just 5 days painful, cystic zits have appeared around my chin and mouth. I havent had acne this bad in about 4 years! I eat an 80% 20% Paleo diet, and the only thing i can attribute to this crazy acne flare up is the collagen.

    Im going to stop taking the supplement for a week or more and write back with progress soon. If anyone has an data/info or feedback let me know! I want to keep taking the collagen because I train a lot and its helping my joints, but not if my skin looks like S#@T!
