Collagen is the most abundant protein in our bodies. It’s found in muscles, bones, skin, blood vessels, digestive system and tendons. Collagen benefits are so striking because this protein is what helps give our skin strength and elasticity, along with replacing dead skin cells. When it comes to our joints and tendons, in simplest terms, it’s the “glue” that helps hold the body together.
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 eight weeks experienced less skin dryness and a significant increase in skin elasticity compared to those who did not take the supplement. The wrinkle-reducing effects of collagen supplements have been attributed to their ability to stimulate your body to produce collagen on its own
Other benefits of Collagen for the body:
Hair and nails: Taking collagen may increase the strength of your nails by preventing brittleness. Additionally, it may stimulate your hair and nails to grow longer (23).
Gut health: Although there is no scientific evidence to support this claim, some health practitioners promote the use of collagen supplements to treat intestinal permeability, or leaky gut syndrome.
Brain health: No studies have examined the role of collagen supplements in brain health. However, some people claim they improve mood and reduce symptoms of anxiety.
Weight loss: Some believe that taking collagen supplements may promote weight loss and a faster metabolism. There have not been any studies to support these claims.
Collagen benefits also include reducing cellulite and stretch marks. When skin loses its elasticity as a result of decreased collagen, there’s another side effect: more visible cellulite. Because your skin is now thinner, cellulite becomes more evident — no more hiding what’s happening below the surface. Collagen for skin helps its elasticity and helps reduce potential dimpling.
Other key benefits: Prevents joint pain, Prevents Leaky Gut and Boosts Metabolism
What type of Collagen should I take?
Collagen supplements, like collagen protein powder, are another easy way to increase your collagen intake. Make sure that you get your powder or supplements from grass-fed, pasture-raised cows (with no antibiotics or chemicals). Collagen supplements can be mixed into smoothies, soups or even into baked goods to provide collagen’s healthy benefits without adding any taste to your favorite meals.
