Of all the supplements that have become trendy lately, perhaps none is as little-understood as collagen. Sure, it's hyped as a way to get glowing skin and luscious hair, improve your flexibility, and turn back the clock on aging, but what exactly is it? And is there any truth to the rumors surrounding this superfood?
Simply put, collagen is a form of protein responsible for making up many structures in your body including skin, bones, and ligaments. Up to 30% of the body's protein is collagen, and it's often thought of as the stuff that binds your body together. Indeed, the word comes from the Greek κόλλα (kólla), meaning 'glue'.
There are actually estimated to be an astonishing 28 different types of collagen in your body, but most of it is Types I, II, and II. Type I is mostly responsible for building and maintaining bones, skin, ligaments, and tendons; Type II maintains cartilage, and Type III takes care of muscles and blood vessels.
As we age, our bodies naturally produce less collagen. But habits like smoking and excessive alcohol consumption, as well as sun damage and poor nutrition, can also impact the amount and quality of the collagen we make. In recent years, people have turned to collagen supplements as a way to improve their health and appearance.
The collagen in most supplements is sourced from bovine (cow) hides as a by-product of meat production, but you'll also find marine collagen from fish (usually the scales and skin). There is unfortunately no such thing as vegan collagen. Research into producing collagen from bacteria and yeast is underway, although there is not yet a commercially-available version.
There are also supplements called collagen builders, which don't actually contain any collagen (so they're potentially safe for vegans and vegetarians) but rather consist of substances to help your body produce more collagen, such as B and C vitamins; minerals like copper and silica; and amino acids. These come in both powder and capsule.
When it comes to format, the most common way to consume collagen is as a powder. These flavorless, colorless powders mix easily into your favorite beverage or smoothie, and you can also incorporate them into things like baked goods and oatmeal. For those who aren't sure if collagen powder is right for them, there's also single-serving packets to try it out. Collagen also comes in capsules, which is convenient for many people. Powdered collagen is generally unflavored, but you'll sometimes see it mixed with vanilla or matcha.
So what does the science say? Many studies are still in their early stages, but initial research looks promising. Some randomized controlled trials have found that taking collagen improved skin elasticity, improved joint mobility, and decreased joint pain. The science does agree that taking collagen internally appears to be more beneficial than using topical collagen skincare products, though.
Nutritionists are also quick to note that because it contains only some amino acids and not all of them, collagen is not a complete protein and should only be used to supplement your regular protein intake, not replace it. Whatever your reasons for taking it, collagen can be a beneficial addition to your daily supplement regime.
