However what does the science say?
What’s collagen?
Collagen is a serious structural protein in our tissues. It is present in pores and skin, hair, nails, tendons, cartilage, and bones. Collagen works with different substances, similar to hyaluronic acid and elastin, to keep up pores and skin elasticity, quantity, and moisture. It additionally helps make up proteins similar to keratin that type pores and skin, hair, and nails.
Our our bodies naturally produce collagen utilizing the amino acids from protein-rich or collagen-rich meals like bone broth, meat, and fish. However getting older, solar injury, smoking, and alcohol consumption all lower collagen manufacturing.
Collagen drinks and dietary supplements typically comprise collagen from many alternative sources, similar to fish, cattle, pigs, or rooster. Sometimes, they comprise peptides, quick chains of amino acids that assist make up important proteins within the physique, together with collagen itself and keratin.
What does the science say about collagen drinks and dietary supplements?
Analysis on pores and skin contains:
- A evaluate and evaluation of 19 research, printed within the Worldwide Journal of Dermatology, that had a complete of 1,125 contributors. Those that used collagen dietary supplements noticed an enchancment within the firmness, suppleness, and moisture content material of the pores and skin, with wrinkles showing much less noticeable. That sounds promising, but it surely’s unclear if these pores and skin enhancements have been really as a result of collagen. Many of the trials used commercially out there dietary supplements that contained greater than collagen: nutritional vitamins, minerals, antioxidants, coenzyme Q10, hyaluronic acid, and chondroitin sulfate have been among the many extra substances.
- A couple of randomized, managed trials (see right here and right here) present that consuming collagen dietary supplements with excessive quantities of the peptides prolylhydroxyproline and hydroxyprolylglycine can enhance pores and skin moisture, elasticity, wrinkles, and roughness. However massive, high-quality research are wanted to be taught whether or not commercially out there merchandise are useful and protected to make use of long-term.
Hardly any proof helps the usage of collagen to reinforce hair and nails. One small 2017 research of 25 individuals with brittle nails discovered that taking 2.5 grams of collagen day by day for twenty-four weeks improved brittleness and nail progress. Nevertheless, this small research had no management group taking a placebo to check with the group receiving collagen dietary supplements.
There have not been any research in people inspecting the advantages of collagen supplementation for hair. At present, no medical proof helps advertising and marketing claims that collagen dietary supplements or drinks can enhance hair progress, shine, quantity, and thickness.

These peptides could also be damaged down additional into the constructing blocks that make proteins like keratin that assist type pores and skin, hair, and nails. Or the peptides could type collagen that will get deposited in different components of the physique, similar to cartilage, bone, muscle mass, or tendons. To date, no human research have clearly confirmed that collagen you’re taking orally will find yourself in your pores and skin, hair, or nails.
In case your objective is to enhance pores and skin texture and elasticity and reduce wrinkles, you are higher off specializing in solar safety and utilizing topical retinoids. In depth analysis has already demonstrated that these measures are efficient.
For those who select to attempt collagen dietary supplements or drinks, evaluate the listing of substances and the protein profile. Keep away from dietary supplements with too many components or fillers. Merchandise containing excessive portions of prolylhydroxyproline and hydroxyprolylglycine are higher at lowering wrinkles and enhancing the moisture content material of pores and skin.
Seek the advice of your physician earlier than beginning any new dietary supplements. People who find themselves susceptible to gout or produce other medical circumstances that require them to restrict protein mustn’t use collagen dietary supplements or drinks.
