Now Green Tea Extract Review

NOW Green Tea Extract 400 mg Veg Capsules provide cellular protection and act as a potent free radical scavenger with the added antioxidant power of Vitamin C. This supplement offers a convenient way to obtain the active constituents of green tea in a concentrated form. Green tea extract contains numerous bioactive compounds, including polyphenols and catechins (with a minimum of 40% catechins per 400 mg leaf extract serving), which are known for their many health-supporting properties. These bioactive compounds have been found to help maintain tissue health by neutralizing free radicals and may also help to maintain a healthy response to normal metabolic stress. Each single veg capsule serving also delivers 60 mg of Vitamin C (as Ascorbic Acid), representing 67% of the Daily Value, alongside approximately 10 mg of naturally occurring caffeine. The product color is brown, though natural color variation may occur. For suggested usage, adults should take 1 capsule daily with a meal, and should not take this product on an empty stomach or exceed the recommended dose. Because it is formulated for adults only, individuals should take it with food and consult a physician if pregnant or nursing, taking medication, or having a medical condition including liver impairment, and keep it out of reach of children. Other ingredients include hypromellose (cellulose capsule) and stearic acid from a vegetable source. It is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut, or sesame ingredients, and is produced in an Intertek GMP certified facility that processes other ingredients containing these allergens.
