Nitric Oxide Accelerator is an additional support for TRIAD 3 Cardiovascular issues by improving nitric oxide levels. Contains L- arginine & L-citrulline, critical factors needed to support nitric oxide production, along with herbs including Cocoa bean extract (99% theobromine) that support the NOS enzyme production and thereby the production of nitric oxide. Nitric oxide is important in endothelial, cardiovascular and neurological function, especially so in men’s health. This product is appropriate if there is adequate BH4 and NADPH. If these are deplete, the L-arginine will turn into super-oxide and then the damaging peroxynitrite. If NOS uncoupling is suspected a better first choice would be NOS Assist.
