A combined L-Arginine (in HCl form) and L-Citrulline supplement from Source Naturals, targeting nitric oxide production, with a slightly higher arginine dose per tablet but requiring multiple servings for full efficacy.
This Source Naturals product offers a combination of L-Arginine Hydrochloride (750mg) and L-Citrulline (250mg) per serving, alongside a minimal calorie count. The inclusion of L-Arginine HCl is notable as it is a common and generally well-absorbed form of arginine. Similar to other supplements in this category, it aims to boost nitric oxide levels for improved blood flow, muscle pump, and cardiovascular health. While the L-Arginine dose is slightly higher than the NOW Sports options per serving, the L-Citrulline dose remains quite low, and overall, multiple tablets would still be required to achieve dosages typically associated with significant benefits in fitness or cardiovascular research. It's a reliable option, but not the most economical for higher dosages.
