Dietary nitrate that reaches nitric oxide by a second route, independent of the arginine pathway.
Beet Root (Beta vulgaris) extract supplies dietary nitrate, which converts to nitric oxide by a route separate from the enzyme L-Arginine depends on.
This nitrate-nitrite pathway is the reason beet juice appears so often in exercise and circulation research, though again, at amounts far larger than the 50mg included here.
JellyBlue includes Beet Root alongside L-Arginine HCl and Grape Seed Extract, together forming the formula's circulation-support trio.
