There are many dangerous free radicals such as: Superoxide, lipid peroxidation, ozone, hydrogen peroxide and hydroxyl radicals that cause many cell damage.
Many studies have proven that the attack of free radicals causes more than 60 different diseases, including particularly dangerous diseases such as: dementia, memory loss, senility, Alzheimer's disease, etc. stroke, essential hypertension, diabetes, atherosclerotic disease, cancer.

Oxidation of cell membranes interferes with the elimination of waste and absorption of nutrients nutrients Attack the mitochondria and disrupt the energy supply. Oxidation and weakening of hormones, enzymes that prevent the body from growing. As a result, chain reactions cause damage to cell membranes, protein molecules and even DNA... leading to changes that damage, dysfunction of organs, even cause cell death. cell .
