    Amino Acid

    • Conditionally Essential Amino Acid
    • Nitric Oxide Precursor

    L-Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as DNA synthesis and protein production. It is an important precursor of Nitric Oxide (NO) and thus plays a role in the dilation of blood vessels.

    Take 2 capsules twice daily as needed. Take between meals or at bedtime with a carbohydrate drink to facilitate absorption.

    Other Ingredients

    Gelatin (capsule), magnesium stearate (vegetable source) and silica.

    Good vitality booster when taken with D-Ribose

    Posted by iHerb Customer on Nov 24, 2017 | Verified Purchase

    I've found this L-Arginine boosts my cognitive vitality when taken with D-Ribose by Healthy Origins (see review) for support of chronic fatigue syndrome. The two together allow me enough energy to do my chores, though I have to take this combo each as one cap every 1.5 to 2 hours. I've contacted both manufacturers to ask for time-released versions of these meds.

    Thanks for your feedback!
