Alpha Lipoic Acid – the “New Kid” Antioxidant

February 25, 2008 by GiGi

Welcome back!

This is first in my series of anti aging supplements. See my original article here: Do You Need Anti Aging Supplements?

Although Alpha lipoic acid has been known since the 1950s, it was originally thought to be a vitamin and wasn’t classified as an antioxidant until 1988.

All antioxidants basically work the same – they are chemicals that get rid of free radicals — destructive chemicals produced by the body and thought to contribute to aging and ailments ranging from heart disease to stroke.

What’s Different About Alpha Lipoic Acid?

Alpha Lipoic Acid is soluble in both water and fat, which means it can move into all parts of the cell to neutralize free radicals. It’s the only antioxidant that can reach the brain.

It is a metabolic antioxidant, which means it is important for cell metabolism or the energy of the cell.

The body actually makes enough alpha-lipoic acid for cell metabolism,however it acts as an antioxidant only when there is an excess of it and it is in the “free” state in the cells. There is little free alpha-lipoic acid circulating in your body, unless you consume supplements.

It is easily absorbed when taken orally, and once inside cells is quickly converted to its most potent form, dihydrolipoic acid.

What’s the Best Form of Alpha Lipoic Acid?

Actually, there are two forms of Alpha Lipoic Acid and if you’re not careful, you could be taking the wrong form. Most supplements are selling a type of Lipoic Acid that consists of BOTH forms of the antioxidant, called S and R. You should be looking for R – Lipoic Acid which is the only form of lipoic acid that your body synthesizes and can safely metabolize.

Unless the label specifically states that it is R Lipoic Acid, you are probably getting the blend.

What Are The Benefits of Alpha Lipoic Acid?

It is currently used in Europe to treat peripheral nerve degeneration (neuropathy) resulting from diabetes.
It helps make Vitamin C and Vitamin E work better
It is used to treat and detox the liver
Protects and repairs cells
Research is discovering it may be helpful in treating or preventing cataracts, atherosclerosis, strokes and heart attacks, and memory and brain function.

Are there Any Side Effects?

Alpha Lipoic Acid seems to have very few side effects. The recommended dosage is between 50 – 100 mg per day. Higher doses can result in nausea and upset stomach.

As always, you should check with your physician before taking any supplements and also look into hormone and vitamin deficiency testing.
