R1 Citrulline Powder | Muscle Pump, Endurance & Nitric Oxide Support

R1 Citrulline is a pure amino acid supplement designed to boost muscle pumps, improve endurance, and enhance overall workout performance. From the very first scoop, R1 Citrulline supports nitric oxide production, which helps increase blood flow to working muscles. As a result, your body delivers oxygen and nutrients more efficiently during intense training.

Manufactured by Rule One Proteins, this unflavoured formula fits perfectly into any custom supplement stack. Moreover, R1 Citrulline contains no stimulants, sugar, or unnecessary fillers. Therefore, athletes can safely combine it with pre-workouts, BCAAs, or intra-workout drinks without changing flavour or texture.

L-Citrulline plays a key role in circulation and endurance. In addition, better blood flow supports stronger muscle pumps and longer training sessions. Consequently, many bodybuilders and strength athletes rely on R1 Citrulline for stimulant-free performance support.
