Key differences

Common forms
- L-Tyrosine · 70% bioavailability
Option B
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.
