What the evidence says
Collagen peptides are collagen protein from cattle hide, broken into small pieces that dissolve and digest easily. Trials report modest gains in skin hydration and elasticity and, in some studies, less exercise-related joint discomfort, but the positive results come largely from company-funded trials: a 2025 analysis found no skin effect in trials without company funding. Collagen is not a complete protein and should not replace other protein in your diet.
How it works
Collagen is the main structural protein in skin, tendons, cartilage and bone. When you digest collagen peptides, amino acids (mainly glycine and proline) and some small peptides enter the blood. The theory is that these supply raw material and may signal the cells that build collagen. Direct human evidence for that is thin: in a 2025 study, 30 g of collagen after exercise raised amino acids in the blood but did not speed up the building of connective tissue protein in muscle.
The dose in this product
The label serving is one 20 g scoop a day. Trials used less: mostly 2.5 to 10 g a day for skin (8 to 12 weeks), 5 to 10 g for joint comfort (12 to 24 weeks), and 15 g in most training studies (the four tendon trials used 5, 15 or 30 g).
How that compares with the studiesHide the comparison
No trial reviewed here compared 20 g with a smaller amount, so a full scoop has not been shown to work better. A half scoop provides 10 g of collagen (about 9 g of protein and 35 calories), which sits at the top of the range used in the skin and joint trials; at that amount a tub lasts 28 days instead of 14. Most skin trials used fish collagen and the main joint trials used a branded pork-derived peptide, not generic bovine hide collagen, so results may not carry over exactly.
No bone claim is made: the main bone trial gave 5 g a day of a specific branded peptide for 12 months to postmenopausal women who already had reduced bone density, a patient group, and was part-funded by the maker. No muscle claim is made: collagen lacks the essential amino acid tryptophan, scores zero on the standard protein-quality scale, and stimulated muscle protein building less than whey in head-to-head tests.
- Moderate evidence
May support skin hydration and elasticity
A 2023 meta-analysis of 26 randomized trials (1,721 people, mostly women) found better skin hydration and elasticity with hydrolyzed collagen, usually 2.5 to 10 g a day for 8 to 12 weeks, though only one trial used bovine collagen like this product. A 2025 meta-analysis of 23 trials (1,474 people) found the benefit only in company-funded trials; trials without company funding, and higher-quality trials, showed no effect. [1][2]
- Early evidence
May support joint comfort during physical activity
In a 12-week trial of 180 active adults aged 18 to 30 with exercise-related knee discomfort and no diagnosed joint condition, 5 g a day of a pork-derived collagen peptide lowered discomfort during activity by about 22 points on a 100-point scale, against 16 with placebo; the trial was part-funded by the peptide's maker. A separate 12-week trial of 10 g a day in 167 active adults (median age 63) found no difference from placebo. [4][3][5]
- Early evidence
Alongside resistance training, may support tendon adaptation
A 2024 meta-analysis of collagen peptides taken with training (19 trials, 768 healthy adults) pooled four small trials that measured tendons (114 people; 5, 15 or 30 g a day) and found larger gains in tendon size but no difference in tendon stiffness; the authors rated this evidence as very low certainty. In a 2025 study, 30 g of collagen after exercise did not speed up connective tissue protein building in muscle. [6][7]
Strong evidence: many human trials agree, at the amount in this product. Moderate evidence: human trials mostly agree, but they are small, short or mixed. Early evidence: a few small human studies or lab work. Promising, not proven.
Safety
Who it is for, and who should ask first
Good fit if
- Adults who want to try collagen for skin hydration and elasticity and can give it 8 to 12 weeks
- Active adults with exercise-related joint discomfort and no diagnosed joint condition
- People who do resistance training and want to add collagen alongside it
- People who eat beef products (it is made from cattle hide, so it is not vegetarian or vegan)
Ask your doctor first if
- You are pregnant or nursing (the trials reviewed here did not include pregnant or nursing women)
- You have kidney disease or have had kidney stones
- You have been told to limit protein
- You are allergic to beef or gelatin
- You have joint pain or swelling that has not been checked by a doctor
Interactions
- No drug interactions were reported in the collagen trials reviewed here, but interaction studies have not been done
- Each scoop adds 18 g of protein, which matters if your doctor has set a protein limit
Possible side effects
- The trials reviewed here reported no side effects linked to collagen, including a 12-month trial at 5 g a day and short studies at up to 60 g a day
- The 20 g label serving is larger than most trials used, so there is less data on how well that amount is tolerated over months
Upper limit
No tolerable upper intake level has been set for collagen. Most trials used 2.5 to 15 g a day for up to 12 months. A 2021 systematic review of 15 trials found no side effects reported, including in short studies at 60 g a day (Khatri 2021, Amino Acids).
This product's 20 g serving is above the usual trial range.
Combining with our other products
Collagen Peptides and Collagen Peptides Chocolate each supply 20 g of collagen per serving. Taking both gives 40 g a day, which no trial reviewed here supports; choose one. Collagen is not a complete protein, so it does not replace Plant Protein, but the two can be taken together.
The unflavored version declares no sodium. Collagen contains no vitamin C, which the body's collagen-building enzymes need; Immune Support (180 mg) and Men's Multi (150 mg) both supply it, though no training trial has compared collagen with and without vitamin C.

Answers
Questions people ask
Should I take a full scoop or a half scoop?
The label serving is one 20 g scoop. Most trials used 2.5 to 15 g a day, so a half scoop (10 g) sits inside the range that was studied for skin and joints. No trial reviewed here compared 20 g with 10 g, so a full scoop has not been shown to work better.
How long before I might notice a difference?
Skin trials ran 2 to 12 weeks, with clearer results after 8 weeks or more. Joint trials ran 12 to 24 weeks. Training studies, including the tendon ones, ran at least 8 weeks.
Does collagen count toward my daily protein?
Only partly. A scoop has 18 g of protein, but collagen lacks the essential amino acid tryptophan and scores zero on the standard protein-quality scale. In head-to-head tests, whey stimulated muscle protein building more than collagen. Use it alongside complete proteins, not instead of them.
How good is the evidence for skin?
It is mixed. A 2023 analysis of 26 small trials found better hydration and elasticity. A 2025 analysis of 23 trials found that benefit only in company-funded trials; trials without company funding, and higher-quality trials, showed no effect.
Is bovine collagen the same as the collagen used in the studies?
Not exactly. Of the 26 skin trials in the 2023 analysis, 14 used fish collagen and only one used bovine. The main joint trials used a pork-derived peptide of a defined size. This product is a generic bovine hide collagen, and we know of no published trial of this exact ingredient.
Is it suitable for vegetarians, or certified halal or kosher?
It is not vegetarian or vegan because it is made from cattle hide. The supplier lists it as gluten-free, lactose-free and corn-free. The supplier does not list halal or kosher certification.
Is it safe to take every day?
Trials lasting up to 12 months reported no side effects linked to collagen, and no upper limit has been set. The 20 g serving is larger than most trials used. Check with your doctor first if you have kidney disease, a history of kidney stones, or are pregnant or nursing.
Why are there no claims about bones, muscle, hair or nails?
The bone evidence rests mainly on one 12-month trial in postmenopausal women who already had reduced bone density, using a specific branded peptide. For muscle, collagen performs worse than complete proteins. Hair and nail studies are few and were not reviewed in depth for this page, so no claim is made.
