NOW Foods Alpha GPC 300 mg Review

Alpha GPC 300 mg Veg Capsules from NOW Supplements is presented as a cognitive support product, listed on the page under the tagline Brain Support. The product description highlights two main points: that it enhances nerve cell communication and that it is a bioavailable source of choline. Each veg capsule supplies 300 mg of Alpha GPC, also written as L-alpha-glycerylphosphorylcholine. The page explains that Alpha GPC is a physiological precursor to acetylcholine, a neurotransmitter involved in memory and other cognitive functions. According to the page, Alpha GPC is more bioavailable than other forms of choline and is known to cross the blood brain barrier. In the brain and other neural tissues, the page states that Alpha GPC becomes a constituent of cell membranes, which it says enhances nerve cell communication and brain function. The product is listed with a color of Off White, and the page notes that natural color variation may occur. The bottle is shown in a 60 veg capsule size, with a serving size of one veg capsule and 60 servings per container. The suggested usage is to take one capsule one to two times daily with food, best taken early in the day. The page advises storing the product in a cool, dry place after opening. The caution section states that the product is for adults only, and that adults should consult a physician if pregnant or nursing, taking medication, or having a medical condition. The product is listed with Intertek GMP Supplement Certification, Kosher (Triangle K), Vegan, Made w/o Dairy, Made w/o Eggs, Gluten Free, and Made w/o Nuts badges. The label states that the product is not manufactured with yeast, wheat, gluten, 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 it is made and quality tested in the USA with globally sourced ingredients. NOW describes itself as family owned since 1968, and notes that the bottle is made from 100 percent PCR post-consumer recycled resin. The page includes the standard statement that the 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.
