NOW Sports L-Citrulline 750 mg Review
NOW Foods L-Citrulline 750 mg is offered as 90 vegetarian capsules and is presented on this page as a product that supports protein metabolism. The page explains that citrulline is a non-essential amino acid and an important intermediate in the urea cycle, where it works along with other amino acids to remove ammonia, a byproduct of protein metabolism. The page also states that citrulline plays an important role in the healing process and in the maintenance of a healthy immune system. The product is listed with a SKU of 0083 and a UPC of 733739000835. Each serving is two veg capsules, and the container holds 45 servings. Each serving provides 1.5 grams, or 1,500 mg, of L-citrulline and 5 calories. The page notes that the daily value has not been established for citrulline. The suggested use is to take one to two capsules, one to two times daily, between meals. The capsules are made from hypromellose, with stearic acid from a vegetable source and silicon dioxide as the other ingredients. The product is marked halal, kosher under the Triangle K symbol, non-GMO and vegan. The label states that it is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients, although it is produced in a GMP facility that processes other ingredients containing these allergens. The page says the product is made and quality tested in the USA with globally sourced ingredients. It also describes the company as family owned since 1968 and says the bottle is made from 100 percent post-consumer recycled resin. Natural color variation may occur in the product. Storage instructions advise keeping it in a cool, dry place after opening. The caution section says the product is for adults only and advises consulting a physician if pregnant or nursing, taking medication, especially meds, nitrates or other vasodilating drugs, or having a medical condition, especially abnormal blood pressure. The page includes the standard statement that these claims have not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, treat, cure or prevent any disease. The current price shown is a special price of $22.39, down from a regular price of $27.99, which is a 20 percent discount.
