L-Arginine (Sustained Release) is an advanced dietary supplement designed for adults interested in overall cardiovascular health, including maintaining healthy blood pressure in the normal range.* L-Arginine SR features the amino acid L-arginine in a unique vegetable-based wax matrix that releases L-arginine gradually. An optimal blood level of L-arginine is critical for vascular health. Your endothelium – the layer of cells that line your blood vessels – relies on this amino acid for a healthy production of nitric oxide. In turn, nitric oxide plays a key role in vascular health, including promoting blood vessel relaxation and optimal blood flow.* L-Arginine SR allows your body to not only absorb L-arginine, but also maintain an optimal blood level to support blood vessel function – without an excessive amount of arginine typically found in regular immediate-release forms.* L-Arginine SR provides 350 mg of L-arginine in each easy-to-swallow tablet. In addition, it’s free of salt, starch, preservatives, artificial color or flavorings, and common allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat and soy). As with all dietary supplements, consult your physician prior to use if you have or suspect a medical condition, are taking any medications, or are nursing or pregnant. See label for more details. *These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease
