Key Ingredients
-
L‑Citrulline — 5,000 mg per serving (pure powder) — a non‑essential amino acid that converts to L‑arginine and can support normal nitric oxide production and related vascular function in healthy adults.*
-
Formulation: single‑ingredient (raw L‑citrulline), unflavored — good for stacking with other sports nutrition products or creatine/pre‑workout mixes.
Directions for Use
Directions for Use
Mix 1 scoop (5 g) with 8–12 fl oz of water or beverage of choice. Consume as directed by your diet/fitness plan. Do not exceed recommended serving unless instructed by a qualified healthcare practitioner. Follow the dosing pattern you and your practitioner determine is appropriate. (Label shows 1 scoop = 5 g; 60 servings / container).
Clinical Research Highlights
-
Systematic reviews and randomized trials indicate oral L‑citrulline supplementation increases plasma citrulline/arginine and nitrate biomarkers and, in some studies, has been associated with small improvements in exercise performance measures (e.g., time trials, reduced perceived exertion) and reductions in resting blood pressure in short‑term trials. Evidence is mixed across protocols and outcome measures. More research is required to establish consistent effects.
-
Meta‑analytic data show L‑citrulline may produce modest reductions in blood pressure in some populations in short‑term studies; results vary by dose, population, and study design.
-
Some recent trials report no significant benefit on selected performance outcomes, highlighting that effects can depend on dose (commonly 2–6 g/day or higher for acute ergogenic protocols), timing, and population. If clinical insights matter for your use case, consult the original studies or your healthcare practitioner.

Do not use if pregnant or nursing. Check with your healthcare practitioner before use if you are under 18, have a medical condition, or are taking prescription medications — especially vasodilators, nitrates, or blood‑pressure medications, as L‑citrulline can affect nitric‑oxide pathways and circulation.
