Collagen powders are made up of hydrolyzed collagen peptides, which are basically just short-chain amino acids. These are small enough to actually be absorbed by the body (collagen itself is too large for a molecule to be absorbed, which is why powders are hydrolyzed and therefore digestible). Once in the body, these peptides have been shown to promote, support and maintain the fibroblasts in your skin cells. * Fibroblasts are actually the parts of your skin cells that produce collagen and elastin.
OK, translation? Healthy fibroblasts mean healthy collagen levels. All of this is important for skin density as collagen is the main structural protein in the skin. And when you are better able to maintain your collagen levels, which unfortunately decrease significantly with age, you can improve your skin barrier function. Research shows that taking collagen supplements can help maintain skin density. *
However, in mindbodygreens grass-fed collagen +, you also have a ton of antioxidants to better support your skin and protect it from free radical damage. First, there is vitamin C, which has been shown to support collagen production synthesis, stabilize the collagen that is already present and naturally protect the skin from environmental influences such as UV rays or environmental pollution. * (It also contains vitamin E to help maintain collagen production, the effectiveness of the former antioxidant.)
Finally, there is hyaluronic acid. This is naturally present in the body – it too begins to decrease with age. Its main job is to keep the moisture in the skin as a naturally occurring humectant. * Since skin thickness is closely related to hydration, keeping the skin hydrated is also of the utmost importance. *
