L-Citrulline is converted to L-arginine in the kidneys, which can increase nitric oxide production to help relax blood vessels and support blood flow.
Caution: May cause stomach upset in some people; start with the suggested serving to assess tolerance.
L-Arginine serves as a direct substrate for nitric oxide synthase to form nitric oxide, supporting vasodilation and circulation.
Caution: Can cause gastrointestinal discomfort in some users and may interact with blood pressure-related regimens due to vasodilation effects.
Taurine helps regulate cellular osmotic balance and calcium signaling, which may support exercise performance and muscle cell function.
Caution: May cause mild drowsiness in some people; consider taking earlier in the day to evaluate personal response.
L-Norvaline is thought to inhibit arginase, which may help maintain higher L-arginine availability for nitric oxide production.
Caution: Human research is limited; use as directed and monitor for unusual effects.
Panax ginseng contains ginsenosides that may modulate nitric oxide pathways and support perceived energy and endurance.
Caution: May be stimulating for some; avoid taking close to bedtime.
L-citrulline and L-arginine provide complementary routes for raising nitric oxide, with citrulline sustaining arginine levels and arginine serving as the immediate precursor. L-norvaline may reduce arginine breakdown, while taurine supports cellular function during exertion. Panax ginseng adds adaptogenic support that can complement stamina-focused ingredients.
Label Warning: If any reactions occur, stop use and consult a doctor. Use only as directed. Pregnant or nursing individuals, children under 18, and those with known medical conditions should consult a doctor before use.
Who should be cautious: People with low blood pressure, cardiovascular concerns, or on blood pressure medications may be sensitive to nitric-oxide–related ingredients like L-arginine and L-citrulline. Those with herpes history may wish to discuss arginine-containing products with a healthcare provider. Individuals sensitive to niacin may experience flushing. If you take medications, discuss with a healthcare provider before use.
