Exercise performance, Circulation support, Workout endurance
Active adults seeking pre-workout circulation support or individuals whose diet is low in arginine-rich foods such as nuts, seeds, and legumes.
Take 3 capsules once daily with 8–12 oz of water; taking with a light meal can improve stomach comfort. For workout use, many people take nitric oxide formulas 30–60 minutes before exercise.
Non-GMO; Gluten-Free. Contains: Gelatin capsule.
L-arginine serves as a substrate for nitric oxide synthase to produce nitric oxide, which may support blood vessel relaxation and circulation.
Caution: May interact with blood pressure or erectile dysfunction medicines due to effects on vascular tone; start cautiously and monitor how you feel.
Provides L-arginine in a salt form that delivers the same nitric oxide precursor to support endothelial nitric oxide production.
Caution: Similar considerations as L-arginine; those with low blood pressure or using vasodilatory supplements should use care.
Combines L-arginine with alpha-ketoglutarate, supplying nitric oxide substrate while alpha-ketoglutarate participates in energy metabolism pathways.
Caution: May cause gastrointestinal discomfort in some people; taking with food and water may help tolerance.
L-citrulline is converted in the kidneys to L-arginine, supporting sustained nitric oxide production and blood flow.
Caution: May influence blood pressure; avoid combining with multiple vasodilatory products without guidance.
Delivers L-citrulline for nitric oxide support while malate enters the Krebs cycle, which may aid cellular energy processes.
Caution: Can cause mild stomach upset for some; take with water and assess tolerance.
Arginine directly supplies the substrate for nitric oxide formation, supporting immediate availability. Citrulline is converted to arginine in the body, which may help sustain nitric oxide levels over a longer period. The malate and alpha-ketoglutarate components feed into energy pathways, complementing circulation support for exercise performance.
Label Warning: For healthy adults aged 18 years and older. Consult a healthcare professional before use if pregnant or nursing, taking medication, or have a medical condition.
Who should be cautious: People with cardiovascular concerns, low blood pressure, kidney issues, or those prone to cold sores may wish to be cautious with arginine and citrulline. If you experience headaches or stomach upset, consider reducing dose. Consult a healthcare provider before combining with medications if uncertain.
Storage: Store in a cool, dry place.
