GrapineŽ, High-Potency [Immune, Vital Nutiriton] is an optimal blend of the powerful antioxidant proanthocyanidins derived from grape seeds and maritime pine bark. Grapine’s proanthocyanidins readily cross the blood–brain barrier to help protect vital brain and nerve tissue from oxidative damage. They are among the most powerful antioxidants found in nature. Antioxidants help to neutralize free radicals—highly active molecules that cause cell damage. Each tablet supplies 60 mg of proanthocyanidins. Take 1 mg of proanthocyanidins per pound of body weight daily with a meal. For example, if you weigh 120 lbs., you would take 120 mg (2 tablets) daily.Stock No. 1699-3 (60)
