Bulk Citrulline Malate Powder 2:1

by Bulk

GMP Third-Party Tested

Citrulline malate in a 2:1 ratio (two parts L-citrulline to one part malic acid), the form most studied for exercise performance. Citrulline boosts nitric oxide production, improving blood flow, muscle pumps, and exercise endurance. A pre-workout staple that can be added to any drink mix. Bulk's 250g pouch delivers the ingredient at one of the lowest prices per serving in the UK.

AI Review Summary

Bulk's Citrulline Malate is one of the most evidence-backed pre-workout ingredients available, and this is the cheapest way to get it in the UK. The 2:1 ratio matches the form used in clinical trials showing improved endurance, reduced fatigue, and enhanced blood flow. The 6g serving provides a clinically effective dose. Zero additives and a tolerable sour taste make it easy to add to any pre-workout mix. One of the few gym supplements where the science genuinely supports the marketing claims.
