I hate to break it to you Muscle Milk lovers but this protein contains an ingredient called Clycocyamine(G-amine)
that is said to cause homocysteine.
Unfortunately, consuming this chemical seems to have the undesirable effect of elevating blood levels of a substance called homocysteine, which is a very strong risk factor for cardiovascular disease (Stead et al., 2001). Cardiovascular disease is easily the number one killer in the Western World, and the last thing we need to do is increase our risk for it. Conversely, taking creatine decreases homocysteine levels, raising even more therapeutic possibilities for this supplement. As if to spit on your grave, if you?re supplementing with creatine, G-amine may also decrease its uptake by muscles (Zugno et al., 2003).
