Collagen is one of the most abundant proteins in the body. It makes up the building blocks of our muscles, bones, skin, and digestive system. As our body ages, collagen production naturally decreases. When collagen is hydrolyzed, water is used to break down the chemical bonds so our body can use it.
There have been many studies that have shown that a collagen supplement can help increase skin elasticity as we age. In a randomized controlled trial, patients were given 10 grams of hydrolyzed collagen over 56 days. These patients experienced had a noticeable increase in collagen density and the moisture in their skin. Increase in collagen density can help provide visible benefits such as decreasing wrinkles and more supple looking skin. In a 2015 study, 105 women were given 2.5 grams of collagen peptides over a period of 180 days. The results were a significant reduction in cellulite on the thighs. In a review of 11 studies, 805 patients who were administered collagen peptides orally noticed a positive impact on their skin. This indicates that collagen can help repair the skin, produce softer skin and reduce cellulite as we age.
Collagen has also been found to contain internal properties that promote healing and joint pain relief. A study of 89 long-term care residents with pressure ulcers who were given a concentrated hydrolyzed collagen supplement found that after 8 weeks they saw their wounds healing twice as fast. Collagen peptides have also been shown to help support gut health. It has been shown in studies as a nutrient that aids in helping to repair inflammation in the gut lining. Collagen is beneficial to the gut because it contains of the amino acids glycine, glutamine and proline. These amino acids can help build and maintain healthy connective tissue throughout your digestive tract. Another study found a positive effect of collagen peptides on the gut microbiota. The health of the gut microbiota can also positively affect the metabolism, which can help make weight loss easier.
