L-norvaline is touted as “one of the leading methods to safely and naturally boost nitric oxide levels to new heights.”  High nitric oxide levels are said to accelerate blood flow, oxygen delivery, and muscle action.  It is the chief ingredient in popular body-building supplements including Myonox, Charge, Pump Extrem, and Preseries Bulk. The tissue culture studies show that l-norvaline initially permits brain cells to produce more energy, but, with continued exposure to this amino acid, the cell machinery employed to produce this energy is damaged.  This is the cellular equivalent to revving your car engine too high for a prolonged period of time. L-norvaline is a so-called non-protein amino acid because it is normally not used to make human pro
