L-Citrulline is converted to L-arginine and then to nitric oxide, which may help relax blood vessel walls and support healthy circulation.
Caution: May cause stomach discomfort in some people; start with the suggested dose to assess tolerance.
L-Arginine serves as a direct substrate for nitric oxide synthase to produce nitric oxide, which may support blood flow and nutrient delivery to muscles.
Caution: Can cause gastrointestinal upset in some users; those with low blood pressure or taking blood pressure medicines should be cautious due to potential additive effects.
Taurine helps regulate cell volume and calcium handling in muscle and nerve tissue, which may support exercise performance and recovery.
Caution: May have mild relaxing effects; consider taking earlier in the day to assess personal response.
L-Norvaline is thought to inhibit arginase, potentially allowing more arginine to be used for nitric oxide production.
Caution: Human data are limited; use only as directed and avoid combining with multiple high-arginine products.
Panax ginseng contains ginsenosides that may modulate nitric oxide pathways and support energy and resilience to physical stress.
Caution: May interact with stimulants or caffeine and can affect sleep in some people; avoid taking close to bedtime.
Citrulline raises circulating arginine, while multiple forms of arginine supply immediate substrate for nitric oxide synthesis to support vasodilation. Norvaline may reduce arginase activity, helping preserve arginine for nitric oxide production. Taurine and Panax ginseng add cellular and adaptogenic support during exercise and recovery.
Label Warning: If any reactions occur, stop use and speak with a doctor. Use only as directed. Pregnant or nursing individuals, those under 18 years, and people with known medical conditions should consult a doctor before use.
Who should be cautious: People with cardiovascular concerns, low blood pressure, or on blood pressure or erectile dysfunction medicines may need caution due to arginine and citrulline potentially affecting circulation. Those with diabetes or on blood-sugar-lowering medicines may wish to be cautious with vanadyl sulfate. Individuals sensitive to niacin may experience flushing. Those with hormone-sensitive conditions or taking hormone-related medicines may wish to be cautious with Tribulus and Panax ginseng. People on stimulants or with insomnia may prefer to avoid late-day use due to ginseng. Discuss with a healthcare provider before combining with medications.
Storage: Store away from humidity, heat, and light. Do not refrigerate. Keep out of reach of children.
