Grapenol supplies a high concentration of proanthocyanidins from pure grape seed standardized extract to specifically help counter damage caused by free radicals and oxidative stress. Each free radical may exist for only a fraction of a second but the damage it can cause may be irreversible. Grapenol is indicated for all conditions associated with cardiovascular disease, such as arteriosclerosis, angina, hypertension, cardiac fibrillations and arrhythmias. Grapenol is recommended for cancer, tumors, skin melanomas, fibrocystic breast disease, osteoarthritis, rheumatoid arthritis, joint pain, varicose and spider veins, premature aging and hemorrhoids. The capsules are 100% pure vegetable-sourced. Product ideal for vegans.
