Ingredients explained
L-Arginine
L-arginine is converted by nitric oxide synthase into nitric oxide, which helps relax blood vessels and support healthy circulation during exercise.
Caution: May interact with blood pressure or erectile function medications because it can enhance nitric oxide effects; start cautiously if sensitive to vasodilation.
L-Arginine HCl
Provides L-arginine with a hydrochloride salt form to supply arginine for nitric oxide production and vascular relaxation.
Caution: Those prone to gastrointestinal discomfort may prefer taking with food since arginine salts can upset the stomach in some people.
Arginine Alpha-Ketoglutarate (2:1)
Combines arginine for nitric oxide formation with alpha-ketoglutarate, a Krebs cycle intermediate, to support nitric oxide availability and exercise blood flow.
Caution: May lower perceived blood pressure; use care when combining with other vasodilatory supplements or stimulants around workouts.
L-Citrulline
L-citrulline is converted in the kidneys to arginine, which then supports nitric oxide production and blood vessel relaxation.
Caution: Can enhance the effects of other nitric oxide boosters; monitor for headaches or lightheadedness if sensitive.
L-Citrulline Malate (2:1)
Supplies citrulline for arginine and nitric oxide production along with malate, which participates in energy metabolism during exercise.
Caution: Citrulline may increase pump and fullness sensations during training; adjust workout intensity if you feel flushed or lightheaded.
How they work together
Direct arginine sources provide immediate substrate for nitric oxide synthase, while citrulline supports a sustained rise in arginine by conversion in the kidneys. The malate and alpha-ketoglutarate components participate in energy pathways, complementing vascular support with metabolic co-factors.
Safety and tips
Label Warning: For healthy adults 18 years and older. Consult a healthcare professional before use if you are pregnant or nursing, taking medication, or have a medical condition.
Who should be cautious: People with low blood pressure, heart concerns, or erectile dysfunction medication use may need caution due to arginine and citrulline’s effects on circulation. Those prone to cold sores may wish to monitor, as arginine may affect herpes simplex outbreaks.
Storage: Store in a cool, dry place.
