Doctor's Best Extra Strength Ginkgo (120 mg), 120-Count

Whole-Body Support Against Free Radicals. The cell membranes that make up most of the substance of all our cells are susceptible to oxidative damage from harmful free radicals. Cell membranes consist of double molecular layers of lipids (“lipid bilayers”) that are especially prone to free radical damage via “lipid peroxidation.” The free radical toxins that can cause such damage arise both from external and internal (metabolic) sources. Free radicals are chemically reactive because they possess unstable electron patterns. Oxygen free radicals are especially reactive and are formed naturally by the mitochondria present in all our cells. As the mitochondria use oxygen to make energy from our foodstuffs, they invariably generate oxygen radicals. Our cells use antioxidant nutrients from our foods, along with antioxidant enzymes made within the cells, to scavenge free radicals and thereby prevent their causing damage. Research has shown that consuming antioxidant-rich supplements can help neutralize free radicals and other potentially toxic substances. Many researchers also believe that dietary antioxidants promote healthy aging. The flavone glycosides from Ginkgo biloba leaf extracts are powerful antioxidants that may aid the body in fending off reactive free radicals. Enhances Memory and Brain Capacity. Researchers worldwide have been assessing dietary antioxidants for possible benefits to memory and brain function. There is substantial evidence for positive effects of Ginkgo biloba leaf extract on awareness, attention and other mental performance.
