Opti N O

Opti NO boosts nitric oxide production using L-citrulline, botanicals, vitamins, and minerals to enhance circulation, relax blood vessels, and support healthy vascular function over 40.

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.
