Opti N O

Opti NO is designed to increase nitric oxide production in the body. Instead of relying on L-arginine like most formulas, it features a superior combination of L-citrulline, select botanicals and key vitamins and minerals to boost nitric oxide, relax blood vessels and enhance circulation in men and women over 40.

Giving L-citrulline increases cellular L-arginine much more efficiently than giving L-arginine supplementally thereby reducing damage due to elevated arginase activity and reduced availability of L-arginine for the nitric oxide cycle.
