(NaturalNews) Antioxidants are substances that protect cells against the effects of free radicals -- molecules produced when the body breaks down food or is exposed to environmental toxins and radiation. Free radicals are believed to play a role in heart disease, cancer and other disorders. So it makes sense that antioxidants could help protect or even treat many health problems.

However, some poorly designed studies have given antioxidants mixed results (http://www.naturalnews.com/023357_p...) and resulted in the mainstream media reporting that antioxidants are virtually worthless. But new research provides hard evidence that taking antioxidant supplements long-term produces dramatic benefits in people with multiple cardiovascular risk factors.

That's the conclusion of a randomized, controlled trial of vitamin C, vitamin E, coenzyme Q10 and selenium capsules. The research results, just reported in BioMed Central's journal Nutrition and Metabolism, show these dietary antioxidants produce multiple positive effects on sugar and fat metabolism, blood pressure and arterial flexibility (which allows blood to move freely through the body).

The study was conducted by scientist Reuven Zimlichman and his research team at Wolfson Medical Center in Israel. They randomly divided 70 high blood pressure patients into two groups. One group was given antioxidants supplements and the other took placebo capsules for six months. Those taking the antioxidants received vitamin C (1000 mg/day), vitamin E (400 i.u/day), coenzyme Q10 (120 mg/day) and selenium (200 mcg/day).

Tests at the beginning of the trial, after three months, and again after six months documented that patients in the antioxidant group had marked improvements in their cardiovascular health. They had more elastic arteries and better blood sugar levels. In addition, their cholesterol profiles were healthier with a significant increase in HDL, the so-called "good", heart-protective cholesterol. In fact, the researchers concluded "antioxidant supplements have the potential to alleviate atherosclerotic damage.."

"Antioxidant supplementation significantly increased large and small artery elasticity in patients with multiple cardiovascular risk factors. This beneficial vascular effect was associated with an improvement in glucose and lipid metabolism as well as significant decrease in blood pressure," Dr. Zimlichman said in a statement to the media. "The findings of the present study justify investigating the overall clinical impact of antioxidant treatment in patients with multiple cardiovascular risk factors."

More hopeful news for heart patients: another study by Dr. Zimlichman and colleagues published in the June issue of the Journal of Cardiovascular Pharmacology, found that taking the amino acid L-arginine long-term also helped people with multiple cardiovascular risk factors. In this randomized, placebo-controlled trial, 90 patients were assigned to receive either oral L-arginine capsules or placebo capsules. After six months, tests indicated those taking L-arginine had improved vascular health -- including a significant decrease in systolic blood pressure.

(NaturalNews) Used throughout Europe to prevent and treat a variety of health conditions, grape seed extract is a powerful antioxidant that can be used to benefit the body in many ways. Grape seed has antioxidant, antiallergenic, antihistamine, anti-inflammatory and immune boosting properties and it can be instrumental in helping the body fight viruses, allergens, and carcinogens.

Because of its antioxidant properties, grape seed extract is considered an anti-aging wonder. Antioxidants are the most important nutrients for the skin. The bioflavonoids in grape seed extract help strengthen and protect cell membranes from oxidative damage caused by free radicals. Its antioxidant properties are considered to be stronger than those of vitamin C and Vitamin E. It helps to repair connective tissue while promoting skin enzyme activity. Grape seed extract aids wound healing by helping to regenerate damaged blood vessels and clearing harmful bacteria from the wound.

Wrinkles and sagging skin, a common age old concern, particularly in women, is caused by harmful free radical activity. Aging is caused by years of physical wear and tear on the body and it can be hastened by poor lifestyle choices, such as a poor diet, smoking and the use of drugs and alcohol. Changing to a healthy lifestyle, including proper diet and supplementation, can ward off and even reverse aging. Grape seed extract contains one of the richest sources of oligomeric proanthocyanidins (OPC's), which makes it one of the most powerful antioxidants available. The use of grape seed extract, together with implementing a healthy lifestyle, can make it possible to reverse much of the damage that has caused lines and wrinkles in the skin.

The body can benefit in many other ways from using grape seed extract. It can be used to prevent health problems which include cardiovascular disease, varicose veins, edema, and arthritis. Grape seed extract also acts as a natural anti-histamine, moderating allergic responses by reducing histamine production and boosting the immune system.

Another important area that grape seed extract can help is eye health. Grape seed extract is frequently recommended to combat macular degeneration, cataracts, and eye strain. Studies have shown that 300 mg daily reduces eye strain from prolonged computer use in 60 days.

Grape seed extract can also be effective in treating conditions such as ADD, as it aids in regulating the neurotransmitters in the brain and inhibits the breakdown of norepinephrine and dopamine. Grape seed extract is one of the few antioxidants that can help to protect nerve and brain tissue by penetrating the blood brain barrier.

Some additional benefits which it provides are:

*Prevents formation of plaque in arteries.
*Improves mental alertness and may help to prevent senility.
*Prevents tooth decay
* Helps to prevent osteoporosis
*May interfere with cancer cell growth and proliferation
*May inhibit virus expression and replication in individuals with HIV
*Aids in poor circulation
*Addresses complications due to diabetes
*Relieves constipation
*It is water and oil soluble, delivering antioxidant protection by penetrating cell membranes throughout the body.

These are just some of the benefits that one can derive from grape seed extract, a powerful supplement that should not be overlooked.
