The focus of research on vitamins these days is how antioxidant supplements may play a role in reducing the risk of cardiovascular disease. Antioxidant supplements – E, C, and beta-carotene (a form of vitamin A) – have potential when it comes to health promotion. However, most data available about such health promoting properties of antioxidant supplements are incomplete. And only up to 30 percent Americans are taking some form of antioxidant supplements.

Antioxidants come in two forms. They can either be vitamins or minerals. They help prevent oxygen from reacting with other chemicals in cells. Such reactions – called oxidation – could lead to cell damage which may result in heart disease and cancer.

Antioxidants can be found in a variety of foods, but they are far more common in fresh fruits and vegetables. A health diet of fresh produce could lead to high levels of antioxidants in your body, which could only mean one thing – less free radicals (those harmful molecules that cause cell damage) and a healthier you.

When antioxidants start to work, they destroy the free radicals or break the chain. You see, here’s what happens when you have lots of free radicals in your body. Because they are highly unstable, these free radicals have the tendency to steal or get electrons from stable molecules and in so doing, make those molecules unstable as well, turning them into free radicals. This becomes a long chain and will go on and on until such a chain in broken. This is where antioxidants come in whose sole function is to break the chain and neutralize free radicals.

During the process of neutralization, the antioxidants are neutralized themselves. Hence, they also become oxidized. That is why the body needs a constant source of antioxidants in order to keep combating these harmful free radicals and stop them from multiplying.

With the kind of diet most of us have these days, it is very likely that we may not be getting enough antioxidants from the foods that we eat. And remember that the body needs to replenish its levels of antioxidants constantly. This is where antioxidant supplements come in.  And while antioxidant supplements can’t very well take the place of natural antioxidants, they can however aid in increasing the level of antioxidants in your body.

 

Antioxidants are a class of nutrients that protect the body from damage caused by different factors, most importantly oxidative damage caused by substances called free radicals. Free radicals are known as “reactive oxygen species”, or ROS. They are produced when your body uses oxygen for energy. Just as fire emits smoke as a by-product, ROS are emitted from the conversion of oxygen to energy in the human body, eventually causing oxidative damage to body systems. Free radicals are also created when the body is exposed to pollution, cigarette smoke, car exhaust and other harmful environmental toxins.

There are different types of antioxidants, and most work better when paired with other antioxidants. This is called synergism. Vitamins can be antioxidants, such as vitamins C and E. The tripeptide glutathione, loosely classified as an amino acid, acts as an antioxidant, along with other true amino acids such as methionine. The raw herbs and vegetables we consume contain natural antioxidants called bioflavonoids and carotenoids, which are effective antioxidants on their own, but are more effective when synergistically combined with other antioxidants. Together these nutrients protect your cells from electron robbery at the hands of larcenous free radicals, protecting the body from disease and slowing the inevitable signs of aging.

Antioxidants are important supplements for everyone, but especially for those who exercise on a regular basis. The rational is that exercise is a highly oxidative process and, as a consequence, produces free radicals from aerobic metabolism. Antioxidant compounds help alleviate this process.

Benefits
• minimizes the damage from free radicals
• protects against cell damage
• may assist with prevention of debilitating diseases

 

The antioxidant vitamins found in fruits, vegetables, teas and supplements are proving to be powerful agents in the fight against disease causing free radicals.

The original concept was to take recommended daily allowance (RDA) of vitamins to a level that would prevent acute deficiency diseases like the Sailor’s disease scurvy. These are the standards by which RDA’s were created.

However, in recent years, research has shown that Vitamins taken in higher doses can prevent sever chronic diseases like cancer and heart disease. A debate still rages, but there is a plethora of research being done on Vitamin A, C, E, the antioxidant vitamins.

A National Institute of Health clinical trial involving people at high risk of developing advanced stages of Age-related Macular Degeneration (AMD), showed that patients’ risk decreased by 25 percent when treated with high doses of antioxidant vitamins and zinc.

Another study at the Center for Disease Control and Prevention (CDC) in Atlanta showed that taking Vitamin E along with multivitamins reduced risk from stroke and heart illness. Among patients who took the combination, mortality risk decreased by 15 percent for these two diseases.

This September, the National Institutes of Health (NIH) concluded a study investigating the relationship between Vitamin C and cancer, suggesting that Vitamin C may fight cancer. They found, in a laboratory setting, that high doses of Vitamin C injected directly into the bloodstream killed cancer cells.

Though the current RDA for Vitamin C is stuck at 60 mg, many researchers suggest that raising the RDA to between 100 and 200 mg would be a great way for people to get the antioxidants that they need to maintain overall well being.

Be careful when purchasing vitamins and supplements though. Research has shown that whole food vitamins, or vitamins with their co-factors, are much more effective than isolated nutrients. Nutrition is a complex process of thousands of chemical reactions within our bodies. Vitamins are always better in their natural state—in the foods we eat.

 

Supplements should never be used in place of a poor diet.The smart choice is to look for whole food vitamins to supplement an already good diet for the times you can’t get everything you need at meal time.
