Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production. It is an important precursor of nitric oxide (NO) and thus plays a role in the dilation of blood vessels. The L-Arginine used in this product is pharmaceutical grade. Natural color variation may occur in this product. Review: Great for the gym - I’ve been using NOW L-Arginine 1,000 mg for a while and would definitely recommend it for anyone who works out regularly. I train three times a week for 45 minutes. With L-Arginine I have less fatigue during workouts, and post-workout muscle soreness is minimal. I take it about an hour before and the muscle pump kicks in almost immediately which seems to make the weight exercises move smoothly. One important note is that the tablets are huge, so be sure to swallow them lengthwise. Overall I think this is a good product at a decent price. Review: good quality supplement from a trusted brand - been taking these for a while now to help with circulation and getting a better pump during workouts and i can feel a difference for sure. the tablets are on the bigger side so just take them with a good amount of water and you'll be fine. NOW Foods is a brand i trust and this product lives up to their reputation, feels like quality stuff without any weird stuff added in. really solid value for what you get and i plan on buying these again. ## Features - DOUBLE STRENGTH L-ARGININE: NOW offers this non-GMO, double strength L-Arginine supplement in 1,000 mg tablets. - NITRIC OXIDE PRECURSOR: Arginine plays an important role in the dilation of blood vessels. - CLASSIFICATIONS/CERTIFICATIONS: Non-GMO, Kosher, Soy Free - GMP Quality Assured: NPA A-rated GMP certification means that every aspect of the NOW manufacturing process has been examined, including our laboratory/testing methods (for stability, potency, and product formulation). - Packaged in the USA by a family owned and operated company since 1968. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0013OVX3U | | Age Range Description | Adult | | Allergen Information | Dairy Free, Egg Free, Non-GMO, Nut Free, Soy Free | | Best Sellers Rank | #6,458 in Health & Household ( See Top 100 in Health & Household ) #3 in L-Arginine Nutritional Supplements #739 in Sales & Deals | | Brand | NOW | | Brand Name | NOW | | Color | Off White | | Container Type | Bottle | | Customer Reviews | 4.5 out of 5 stars 14,995 Reviews | | Diet Type | Halal, Kosher, Vegan, Vegetarian | | Dosage Form | Tablet | | Dose Release Method | Immediate Release | | Flavor | Unflavored | | Global Trade Identification Number | 00733739000354, 08720634116398 | | Item Dimensions | 2.7 x 2.7 x 4.75 inches | | Item Form | Tablet | | Item Weight | 0.25 kg | | Manufacturer | NOW Sports - Nutrition and Wellness | | Manufacturer Part Number | 0035 | | Material Features | Vegetarian | | Material Type Free | wheat, gluten, soy, milk, egg, fish, shellfish, sesame | | Model Name | NOW Supplements, L-Arginine 1,000 mg, Nitric Oxide Precursor*, Amino Acid, 120 Tablets | | Model Number | 0035 | | Number of Items | 1 | | Package Size Name | 120 Count | | Pill Coating | vegetarian | | Primary Supplement Type | protein | | Product Benefits | Metabolism Management, Vascular Health Support | | Recommended Uses For Product | Amino Acid | | Special Ingredients | L-Arginine | | Specific Uses For Product | Amino Acid | | Supplement Formulation | Individual Supplement | | Total Servings Per Container | 120 | | UPC | 733739000354 | | Unit Count | 120 Count | ## Product Details - **Brand:** NOW - **Diet Type:** Halal, Kosher, Vegan, Vegetarian - **Flavor:** Unflavored - **Item Form:** Tablet - **Item Weight:** 0.25 kg - **Item dimensions L x W x H:** 2.7 x 2.7 x 4.75 inches - **Primary Supplement Type:** protein - **Product Benefits:** Metabolism Management, Vascular Health Support - **Special Ingredients:** L-Arginine - **Unit Count:** 120 Count ## Images ![Supplements, L-Arginine 1,000 mg, Amino Acid, 120 Tabs - Image 1](https://m.media-amazon.com/images/I/7155wLAKU9L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: is this tested ??** A: Yes from what a health magazine that my wife got states that it has been tested.She has been taking it for over 2 weeks now and she has lost weight from taking it. **Q: Is this a sustained release version of L-Arginine?** A: This is not a 'capsule' with tiny pellets inside, but rather a tablet. It's large so I put it into a couple tablespoons of water overnight and just gulp it down followed by water. **Q: is there an improvement in urination control at night with only 1 capsule they recommend?** A: My husband and I started taking Solaray Olive Leaf Extract to help keep from getting the flu and within a week we both noticed we weren’t waking up in the middle the night. An unexpected positive side affect. 250mg 17% 120caps costs between $24 - 28 here’s the link and worth a try.
