Collagen is a kind of protein present in many animals and humans. According to experts, it is largely composed of three amino acids building blocks of protein and accounts for around one-third of the total protein in our bodies.

Collagen peptides are created by breaking entire collagen proteins into smaller pieces known as peptides. According to experts, the reason you would want to have broken down collagen is because it improves absorption in your body.

When you reach your 30s, your body naturally produces less collagen. In fact, studies suggest that your body’s collagen synthesis decreases by 1 to 1.5 percent every year. However, including collagen peptides in your diet may help you replace them as you age.

Collagen, like other proteins, is broken down before being absorbed by the body. These amino acids, according to experts, can be used for almost everything, not only collagen loss. However, having the specific amino acids for collagen repair on hand will certainly improve the odds.

Collagen peptides may help in hydration and elasticity by bolstering the skin’s existing collagen. Experts say there is a limit to how much skin benefit you may receive from collagen peptides.

Like many dietary supplements, many collagen supplement manufacturers recommend that people take it every day, with lofty promises of healthier-looking skin, healthy joints and more if you follow the directions on the label.

Collagen supplements are typically well tolerated, with few side effects reported. Some supplements, however, are produced from common food allergens such as fish, shellfish, and eggs. Those who are allergic to certain foods should avoid collagen supplements containing these ingredients.

Some people experience nausea and bloating after taking collagen supplements, although research has not consistently demonstrated these as side effects.
