NOW Supplements, Taurine 1,000 mg, Double Strength, 100 Veg Caps Review

Taurine, Double Strength 1000 mg Veg Capsules from NOW Supplements provides 1,000 mg of free-form taurine in each vegetarian capsule. The product is listed in the Amino Acids category and is positioned under the Nervous System Health heading. According to the page, taurine is a conditionally essential amino acid that is not used for protein synthesis but is found free in most tissues, especially throughout the nervous system. The page explains that taurine works by stabilizing cell membranes and aiding the transport of potassium, sodium, calcium and magnesium in and out of cells. It also states that taurine helps generate and regulate nerve impulses and supports the maintenance of normal fluid balance. The body uses taurine in visual pathways as well as in the brain and nervous system, where it works together with glycine and GABA as a neurotransmitter. The Description section lists Healthy Visual Function as a benefit. This product has twice the taurine of the regular strength product, which contains 500 mg. Each capsule is one serving, and the bottle holds 100 veg capsules. The page lists the 250 veg capsule size as a separate option with its own SKU and UPC. The suggested use is to take 1 capsule 1 to 2 times daily with juice or water, preferably between meals. The label advises storing the bottle in a cool, dry place after opening. The Supplement Facts panel lists a serving size of 1 veg capsule and 100 servings per container. Taurine (Free-Form) is listed at 1 g (1,000 mg) per serving, with the Daily Value marked as not established. Other ingredients are hypromellose (cellulose capsule), stearic acid from a vegetable source, and silicon dioxide. The page says the product is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients, but is produced in a GMP facility that processes other ingredients containing these allergens. Certification and quality seals shown on the page include Halal, Kosher (Triangle K), Non-GMO, Intertek GMP Supplement Certification, and Vegan. The page also lists Made w/o Dairy, Made w/o Eggs, Gluten Free, Made w/o Nuts, Made w/o Soy and Vegan / Vegetarian.
