The Free Radical Theory of Aging written by Dr. Denham Harman in 1956 gives a detailed description of free radical, the culprit for human aging and illness, and states that antioxidant which removes the excess free radicals in human body is crucial in preventing illness and delaying aging. Aging and exposure to diseases are primarily due to the process of oxidation. The body is damaged by oxidant, i.e. free radical, which, as the main culprit for various diseases, attacks our body like a bullet, causes lesions to tissue cells and leads to aging.

One of the significant methods against aging is to keep sufficient antioxidants in the organism. Supplementing antioxidants helps to curb free radical generation or speed up its removal to slow down aging. Among the foods that we take, fruits, vegetables and wine have plentiful antioxidants. When food ingestion can not meet the demand, the first choice is taking health foods enriched with antioxidants.

Cranberry is low on calories and rich in vitamins and minerals.

This procyanidin-enriched natural antioxidant is internationally recognized the most effective in clearing free radicals in human body, and in terms of antioxidation, is 20 and 50 times respectively as strong as VC and VE.

A comparison made by the U.S. Department of Health & Human Services between common fruits in 2007 found that cranberry was the best in anti-oxidation.
