About this product
Each vegetarian capsule combines two free-form amino acids. It supplies 500 mg of L-arginine and 250 mg of L-citrulline, with 120 capsules in the bottle.
What it’s designed to support
NOW formulated this combination to support normal protein metabolism and muscle maintenance. Both amino acids take part in the body’s urea cycle.
Who it’s for / Before you buy
For adults. If pregnant or breastfeeding, taking medication, or managing a medical condition, check with your healthcare practitioner before use. The label specifically flags blood-pressure medicines, nitrates and other heart medicines, as well as kidney impairment, herpes and glaucoma.
What to compare
Compare the amount of each amino acid per capsule and per daily serving. Single-ingredient arginine or citrulline products give you control over which amino acid you take.
