Opti-Cell Plus is a very potent antioxidant therapy. Antioxidants are naturally found in many fruits and vegetables. Antioxidants work to block free radicals which in excess could potentially damage healthy cells. This is a blend of standardized botanical extracts including green tea, red wine grapes, milk thistle, bilberry, curcumin and citrus bioflavonoids. Opti Cell Plus also offers nutrients such as high dose vitamin C, lipoic acid, Coenzyme Q10, and several amino acids. These tablets can be taken to compliment the benefits of a healthy diet.
