Key Differences

Arginine Silicate

Arginine silicate inositol (ASI), marketed as Nitrosigine, is a patented complex of bonded arginine and silicon. It demonstrates superior bioavailability compared to standard arginine, with faster onset of nitric oxide boosting effects. Clinical trials show significant improvements in blood flow and cognitive function.

Categories:

Common Forms:

  • • Nitrosigine (55% bioavailability)

Citrulline

L-Citrulline is a non-essential amino acid named after watermelon (Citrullus lanatus). It is converted to L-arginine in the kidneys, making it a more efficient NO booster than arginine itself (arginine undergoes significant first-pass metabolism). One of the most validated pre-workout ingredients for blood flow and endurance.
