Our highly-dosed L-arginine capsules provide a staggering 5000 mg of the important amino acid per serving. In addition to building proteins, L-arginine is also needed for the production of the signaling molecule nitric oxide. Nitric oxide signals the blood vessels to widen (dilate) and thus regulates blood pressure, among other things. In phases of increased demand (e.g. intense exercise, infection), the body's own L-arginine production may not be sufficient, which is why the amino acid is classified as semi- or conditionally-essential. Ambitious athletes and people with an active lifestyle can easily cover their increased L-arginine demand with our convenient capsules.
