If you’re looking for a convenient source of the amino acid L-arginine‚ you might want to consider trying Allergy Research Group’s L-Arginine 500 mg. This product may work to alleviate certain symptoms associated with arginine deficiency‚ such as constipation or hair loss. Arginine is a semi-essential amino acid; this means that while the body usually produces sufficient amounts of it‚ people with certain health conditions may benefit from taking an L-arginine supplement. For that reason‚ every capsule of L-Arginine 500 mg provides 500 milligrams of free-form L-arginine. L-Arginine 500 mg may also play a role in stimulating your immune system. Specifically‚ this amino acid might encourage increased production of lymphocytes (white blood cells)‚ which act to fight off foreign antigens—like bacteria or viruses—that could otherwise make you feel sick. In addition‚ L-Arginine 500 mg may work to promote healthy cardiovascular function. Notably‚ L-arginine may support optimal blood flow because your body converts it into nitric oxide‚ which is a chemical that might work to relax and widen your blood vessels. Take L-Arginine 500 mg by Allergy Research Group between meals. Each 250-capsule bottle should last for about two-and-a-half to eight months at the recommended dosage.
