The Vital drink bought for training support in Ausdauerbreich Running (fat burning / balancing mineral loss). So far I can only good things to say. The post-workout recovery is well supported, what I notice personally at decrease of calf cramps after intensive courses. Even the taste of the drink is fine. I can only recommend the drink for training support. Of course, should also be trained in accordance with u. A little to pay attention to the diet, otherwise bringts nothing. I'm not talking about asceticism u. Selbstgeiselung eating u. During sports. But do u drink. Very little or nothing is useless.
