Collagen is a very large molecule and can most likely not be directly absorbed into your cells. Instead, the body has to expend energy to take the collagen apart into its building blocks - the amino - acids and then reuse these to synthesise collagen. This is also why marine collagen is considered more popular than collagen from bovine origin, as it is a smaller molecule.
Avea has taken a new approach and worked with ETH Zurich scientists to develop Colgevity™. Instead of using whole collagen molecules—which are too large to be absorbed - we focus on highly bioavailable building blocks like proline, glycine, and hydroxyproline. These are directly used in the body to stimulate collagen turnover, making our blend 4x more effective than traditional collagen supplements.
