The primary source of supplemental nitrates for sports formulas has been the amino acid arginine and its precursors. In the case of arginine bonded to silicon, recent evidence shows the sum may be better than the parts. Animal research reported in summer 2016 noted the combination of arginine, silicon and inositol (as Nitrosigine®, from Nutrition 21) led to greater serum and joint tissue levels of both arginine and silicon than in the control groups, including one group taking each individual ingredient at the same time.
