What L-Citrulline HCL is
L-Citrulline is an amino acid first discovered in watermelon. The HCL form is citrulline paired with hydrochloride for stability and absorption.
What L-Citrulline HCL does in MemoClear®
Citrulline is the smart way to raise arginine. It passes through the gut intact, travels to the kidneys and is converted into fresh arginine there. Studies show oral citrulline lifts blood arginine more effectively than arginine itself, and keeps it up for longer. In MemoClear it is the recycling loop: as arginine is used to make nitric oxide, citrulline replaces it, so the cycle keeps turning all day.
The benefit
Keeps the nitric-oxide cycle continuous, so cerebral blood-flow support stays steady between capsules.
Where it comes from in food
Watermelon is the richest source, with smaller amounts in cucumber, pumpkin and other melons.
How it fits with the other MemoClear® ingredients
L-Citrulline HCL works alongside L-Arginine, L-Arginine AKG 2:1, L-Citrulline Malate, Niacin (Vitamin B3), Beta-Alanine. Together they cover cerebral blood flow, brain-cell energy and neuron protection in one daily capsule.
