Finally, look for multiples designed to meet the very different nutritional needs of each age and gender. For example, most women require higher calcium, iron, and vitamin B6 levels than men, while men tend to require higher zinc and magnesium levels. Also, men rarely need to supplement their diet with iron. Teens also have special nutritional needs. I recommend a flax oil complex that contains all three.
Free radicals are toxic molecules that are missing one vital electron.
In an unsuccessful effort to replace that electron, they bind to and destroy healthy cells. This destructive process has been linked to numerous health deficiencies and could actually accelerate the aging process. They're produced in the body during normal metabolic processes such as energy production, detoxification, and immune mechanisms, but lifestyle and environment may also contribute to the body's free radical burden. For example, cigarette smoke greatly increases the level of free radicals in your body which, in turn, depletes the level of vitamin C and beta-carotene. Other external sources of free radicals include ionizing radiation, chemotherapeutic drugs, anesthetics, air pollutants, pesticides, fried foods, alcohol, solvents, and formaldehyde.
