L-Arginine molecular structure surrounded by foods rich in L-Arginine

L-Arginine and Exercise: From Nitric Oxide to Human Research

L-arginine is an amino acid involved in several processes, including the body's production of nitric oxide. Nitric oxide is a signaling molecule involved in blood-vessel function, which is one reason arginine has attracted exercise-research interest.

Our Sweet Peach pre-workout provides 3,000 mg L-arginine per labeled serving. Here is how that ingredient connects with the research.

From a pathway to a performance question

A biological pathway helps explain why scientists study an ingredient. To learn whether supplementation improves exercise, they also need measurements of work performed: a timed task, a capacity test or another defined outcome.

That keeps a change in a blood marker separate from an actual change in athletic performance.

What a review found

A 2020 systematic review and meta-analysis examined arginine supplementation and aerobic and anaerobic performance. The pooled analyses favored arginine, while the included studies differed in participants, doses, schedules and exercise tests.

The aerobic results varied substantially across studies. The positive pooled finding therefore does not provide one guaranteed result or a universal onset time for every serving.

Our arginine and citrulline pair

We list 3,000 mg L-arginine and 3,000 mg L-citrulline individually. Citrulline can contribute to circulating arginine through metabolism, which has also prompted researchers to study the two together.

Our formula includes 2,500 mg beta-alanine and 1,000 mg taurine alongside that pair. The panel lets you see how these ingredients contribute to the composition of a single scoop.

Use the complete product directions

Our serving also supplies 220 mg caffeine from guarana. Follow the container instructions for the whole formula rather than adjusting scoops to copy one ingredient's research protocol.

If you use other supplements, compare the full ingredient lists for overlap. Medication and health-specific questions belong in an individual discussion with your pharmacist or clinician.
