Fast Acting Arginine Complex with Nitrosigine - Short Dated

Short Dated Until January 2027

Doctors Best Fast Acting Arginine Complex contains Nitrosigine® which is a patented ingredient of Arginine Silicate that has been clinically shown to significantly boost Nitric Oxide (NO) levels, which is a key factor in increasing blood flow to working muscles. Nitrosigine® is engineered to take effect in 30 minutes. Nitrosigine® keeps delivering benefits throughout an entire workout, for up to 3 hours with a single dose. With continued use, Nitric Oxide levels build up over time, leading to even better blood flow and vessel flexibility. 

Why Nitrosigine® over L-Arginine? 

Clinical trials of Nitrosigine® have demonstrated superiority over Arginine in elevating blood flow markers. Increased Nitric Oxide levels result in enhanced blood flow, which is beneficial during and after exercise, helping muscle growth and recovery. In trials, Nitrosigine® almost doubles the maximum blood flow compared to control or Arginine HCL.

Fast Acting Arginine Complex with Nitrosigine uses arginine silicate inositol, a patented form of arginine designed to support nitric oxide production. Nitric oxide helps blood vessels relax, which is why arginine products are commonly used for blood flow, workout performance, pump and cardiovascular support.

The potassium comes from the Nitrosigine complex itself, but the main reason to buy this product is the branded arginine form. Nitrosigine has been studied for its ability to raise nitric oxide and support exercise performance and mental sharpness in some settings. In plain terms, it is the sort of ingredient people look at when they want circulation and training support from a non stimulant product.
