In this review, you can find out everything there is to know about a dietary supplement called NOW Sports L-Arginine 500 mg, which is a popular supplement among body builders due to L-Arginine’s alleged Nitric Oxide production capabilities. NOW Sports L-Arginine 500 mg claims, besides increasing Nitric Oxide levels, to supply the body with a boost of essential amino acids, thus greatly improving general metabolism and digestion, as well as supporting DNA synthesis in our bodies with its usage of L-Arginine. If you continue reading this review, you will learn more about the formula, ingredients, recommended dosage, price and money-back guarantee of NOW Sports L-Arginine 500 mg, all brought to fruition in the conclusion.


In order to exact the effect is claims to have, NOW Sports L-Arginine 500 mg contains the following ingredients in its formula:

  • Free Form L-Arginine – 1000 mg
  • Gelatin (capsule)
  • Magnesium Stearate (from plants)
  • Silica

You should always make sure to look out for the ingredients of any supplement you pick, since we are talking about a substance you plan to put into your body. The main concern with the formula is due to an increasing tendency in the dietary supplement industry of certain low-quality manufacturers adding a high amount of unnecessary fillers and binders, or potentially harmful artificial additives, preservative, flavoring ingredients, or coloring agents. As we see here, the formula of NOW Sports L-Arginine 500 mg doesn’t contain any of these, and other than the key active ingredient, the only other components are used in the pill itself.


This product is intended for use by healthy adults. The recommended daily dosage for NOW Sports L-Arginine 500 mg  is flexible, as the product label states that the product can be taken as little as 1 or as many as 3 times every day. On each such occasion, the recommended serving is 2 pills. It is suggested to take the product in between your meals, or right before going to sleep, always with sufficient drink, preferably with a drink that contains a measure of carbohydrates, in order to make sure that the product is properly absorbed.


NOW Sports L-Arginine 500 mg is a product that is available from multiple re-sellers, and each source sets their own prices, so finding one that suits your needs should be easy.


Since NOW Sports L-Arginine 500 mg can be purchased from various re-sellers, they all have their own money-back guarantee policies.


NOW Sports L-Arginine 500 mg may seem like an effective and safe product, however once we dig deeper we realize that only one of those statements turns out to be true. This product entirely safe for use, as it is free of any potentially harmful and pointless artificial additives, however, unfortunately, it is also entirely ineffective, as L-Arginine Alpha Ketogluterate doesn’t actually contribute to the generation of Nitric Oxide in our bodies. There is also the slight issue of a lack of universal pricing and returns policy, putting the unwary customer at the mercy of the re-seller.
