Blood flow support, Exercise performance support, Workout endurance
Active adults looking to support workout performance or people seeking additional nitric oxide precursors due to low intake from diet.
Take 3 capsules once daily with 8–12 oz of water; taking 30–60 minutes before exercise is commonly used for nitric oxide–focused products, and taking with food may improve comfort if you experience stomach upset.
Non-GMO; Gluten Free
L-arginine is converted to nitric oxide, which relaxes blood vessels and supports blood flow during exercise.
Caution: May interact with blood pressure or erectile health products because it can influence vascular dilation; start with the suggested serving to assess tolerance.
Provides L-arginine that the body uses to produce nitric oxide for vascular relaxation and circulation support.
Caution: Similar considerations as L-arginine; those sensitive to gastrointestinal upset may prefer taking with food and water.
Supplies arginine for nitric oxide production and includes alpha-ketoglutarate, a Krebs cycle intermediate involved in energy metabolism.
Caution: May affect blood pressure due to vascular effects; avoid combining with multiple nitric oxide boosters without assessing tolerance.
L-citrulline converts to L-arginine in the body, helping sustain nitric oxide levels and support blood flow.
Caution: Can enhance the effects of other nitric oxide donors; those prone to low blood pressure should monitor how they feel.
Provides L-citrulline for nitric oxide support and malate, which participates in the energy-producing malate-aspartate shuttle.
Caution: May cause mild stomach discomfort in some people; taking with water and away from heavy meals may help.
Multiple arginine sources deliver immediate nitric oxide precursors, while citrulline can be converted to arginine to help sustain levels over time. The inclusion of AKG and malate ties into cellular energy pathways, complementing vascular support during workouts.
Label Warning: For healthy adults 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 who use blood pressure or erectile dysfunction medications may need extra caution due to arginine and citrulline’s effects on blood flow. Those with herpes outbreaks may wish to discuss with a healthcare provider.
