L-Arginine, Powder – 454 grams

This 454g tub of pure free-form L-Arginine powder delivers a single-ingredient formula with no fillers or additives. L-Arginine is a conditionally essential amino acid that plays a key role in urea metabolism, DNA synthesis, and protein production. It is widely recognised as a direct precursor to nitric oxide, making it a firm fixture in the supplement stacks of athletes, bodybuilders, and those with an active training schedule.

Each recommended daily dose of 2 level teaspoons provides approximately 6g of L-Arginine in its free-form state, which is considered highly bioavailable. The unflavoured powder mixes without clumping into water, juice, or a protein shake, giving you complete flexibility over how you take it.

With 454g per tub, this is a practical, no-nonsense format that suits anyone who prefers to dose precisely and keep their supplement routine straightforward. The pure powder format also makes it easy to stack alongside other amino acids or pre-workout ingredients as part of a broader nutrition protocol.
