Product Features: Faster melting and best results Product Benefits: Keratin is used to reinstall ATP or inodine triphosphate which is the part responsible for muscle energy production, when muscle contracts, a break in the chain of links that bind the ATP particles and gives us the ADP (adenonine dimphosphate) where energy is released by breakdown K) These bonds tighten muscles, when ATP is exhausted into the cells, they become unable to shrink. That's why the body uses different methods to reshape the ATP and the fastest way that is non-oxygen, when it disintegrates to give us phosphates this last binds to ADP and forms ATP. Keratin as a dietary supplement increases the proportion of keratin and phosphate keratin within the muscle, allowing it to regenerate ATP more easily, in other words, the keratin increases muscle capacity so it will stay strong during short periods of intense workouts.
