Collagen is a major component of your skin.

It plays a role in strengthening skin, plus may benefit elasticity and hydration. As you age, your body produces less collagen, leading to dry skin and the formation of wrinkles.

However, several studies have shown that collagen peptides or supplements containing collagen may help slow the aging of your skin by reducing wrinkles and dryness.

In one study, women who took a supplement containing 2.5–5 grams of collagen for 8 weeks experienced less skin dryness and a significant increase in skin elasticity compared with those who did not take the supplement.

Another study found that women who drank a beverage mixed with a collagen supplement daily for 12 weeks experienced increased skin hydration and a significant reduction in wrinkle depth compared with a control group.

The wrinkle-reducing effects of collagen supplements have been attributed to their ability to stimulate your body to produce collagen on its own.

Additionally, taking collagen supplements may promote the production of other proteins that help structure your skin, including elastin and fibrillin.

There are also many anecdotal claims that collagen supplements help prevent acne and other skin conditions, but these are not supported by scientific evidence.

Collagen helps maintain the integrity of your cartilage, which is the rubber-like tissue that protects your joints.

As the amount of collagen in your body decreases as you get older, your risk of developing degenerative joint disorders such as osteoarthritis increases.

Some studies have shown that taking collagen supplements may help improve symptoms of osteoarthritis and reduce joint pain overall.

In one study, 73 athletes who consumed 10 grams of collagen daily for 24 weeks experienced a significant decrease in joint pain while walking and at rest, compared with a group that did not take it.

In another study, adults took 2 grams of collagen daily for 70 days. Those who took collagen had a significant reduction in joint pain and were better able to engage in physical activity than those who did not take it.

Researchers have theorized that supplemental collagen may accumulate in cartilage and stimulate your tissues to make collagen.

They have suggested this may lead to lower inflammation, better support of your joints, and reduced pain.

If you want to try taking a collagen supplement for its potential pain-relieving effects, studies suggest you should start with a daily dosage of 8–12 grams

Researchers have theorized that taking collagen supplements may help reduce the risk of heart-related conditions.

Collagen provides structure to your arteries, which are the blood vessels that carry blood from your heart to the rest of your body. Without enough collagen, arteries may become weak and fragile.

This may lead to atherosclerosis, a disease characterized by the narrowing of the arteries. Atherosclerosis has the potential to lead to heart attack and stroke.

In one study, 31 healthy adults took 16 grams of collagen daily for 6 months. By the end, they had experienced a significant reduction in measures of artery stiffness, compared with before they started taking the supplement.

Additionally, they increased their levels of HDL “good” cholesterol by an average of 6%. HDL is an important factor in the risk of heart conditions, including atherosclerosis.

Nevertheless, more studies on the role of collagen supplements in heart health are needed.

Whole grains: Grains such as whole wheat, brown rice and barley still have their fiber-rich outer shell, called the bran, and inner germ. It provides vitamins, minerals and good fats. Choosing whole grain side dishes, cereals, breads and more may lower the risk for heart disease, type 2 diabetes and cancer and improve digestion, too.

Saturated fat: A type of fat found in abundance in butter, whole milk, ice cream, full-fat cheese, fatty meats, poultry skin, and palm and coconut oils. Saturated fat raises levels of heart-threatening LDL cholesterol in your bloodstream. It can also interfere with your body’s ability to absorb blood sugar easily. Limiting saturated fat can help control your risk for heart disease.

Omega-3 fatty acids (oh-may-ga three fah-tee a-sids): Healthy polyunsaturated fats that the body uses to build brain-cell membranes. They’re considered essential fats because our body needs them but can’t make them on its own; we must take them in through food or supplements. A diet rich in omega-3s—found in fatty fish, like salmon, tuna and mackerel, as well as in walnuts, flaxseed and canola oil—and low in saturated fats may help protect against heart disease, stroke, cancer and inflammatory bowel disease.
