Exercise performance support, Blood flow and circulation, Endurance and recovery
Active adults seeking workout circulation support or those who want a simple daily nitric oxide routine.
Take 3 capsules once daily with 8–12 oz of water; taking 30–60 minutes before exercise may be practical for workout use.
Non-GMO; Gluten-free; Contains: Gelatine; Made in a GMP compliant, third-party tested facility.
Arginine is converted by nitric oxide synthase into nitric oxide, which may relax blood vessel smooth muscle and support blood flow during exercise.
Caution: May interact with blood pressure or erectile function products because it can influence vascular tone; start cautiously if sensitive to vasodilators.
Provides arginine that the body uses to generate nitric oxide, which may support endothelial function and circulation.
Caution: May cause gastrointestinal discomfort in some people; take with water and assess tolerance.
Supplies arginine for nitric oxide generation while alpha‑ketoglutarate participates in the Krebs cycle, supporting cellular energy processes.
Caution: Those monitoring arginine intake should account for total arginine from all sources to avoid excessive dosing.
Citrulline is converted in the kidneys to arginine, which may sustain nitric oxide levels and support blood flow.
Caution: May amplify effects of other nitric oxide–supporting supplements; avoid combining high doses without assessing response.
Provides citrulline to raise arginine and nitric oxide, while malate feeds into the energy cycle to support reduced exercise‑related fatigue.
Caution: May cause mild stomach upset in some users; taking with food or splitting doses can help tolerance.
Arginine sources offer immediate substrate for nitric oxide production, supporting vascular relaxation and blood flow. Citrulline sources convert to arginine over time, helping maintain nitric oxide levels for more sustained effects. Malate and alpha‑ketoglutarate feed energy pathways, complementing circulation support during training.
Label Warning: For healthy adults aged 18 and over only. Consult a healthcare professional before use if pregnant, nursing, taking medicine, or if you have a medical condition.
Who should be cautious: People with low blood pressure, cardiovascular concerns, kidney issues, or herpes history may need caution with arginine and citrulline. Those using blood pressure medicines, nitrates, or erectile dysfunction medicines should discuss with a healthcare professional before use.
Storage: Store in a cool, dry place.
