The medical community is recognizing alpha-lipoic acid more and more as an important antioxidant. It is not only both fat & water soluble; it also has the ability to readily cross over the blood brain barrier. It can regenerate Vitamin C, Vitamin E, intra cellular glutathione and CoQ10.
Another important aspect of alpha-lipoic acid is that it can attach itself to toxic metals in the brain and help eliminate them from the body. Heavy metals such as mercury, aluminum, cadmium, and lead have been implicated in increasing the risk of developing neurodegenerative diseases. These metals tend to deposit themselves in brain tissue because of the high amount of fat concentrated in that part of the body. These metals can cause a significant increased amount of oxidative stress and are extremely difficult to remove from the central nervous system once they are there. Antioxidants that not only are potent but have the ability to help remove these toxic heavy metals will become increasingly important in the prevention and treatment of these diseases.
As a side note, I believe it is wise to eliminate the use of products, such as deodorants and cooking utensil that contain aluminum. When you realize that heavy metals actually increase the amount of oxidative stress in the body, especially the brain, you will want to decrease your exposure to them.
I anticipate that over the next several years we will hear more & more about mercury toxicity and how it too can cause significant damage to the brain. I would encourage everyone, but especially those with children to avoid getting mercury amalgam fillings in their teeth. If you ask your dentist possible alternatives to these mercury amalgams, he does have much safer option. But don’t run out and have all your mercury fillings removed, through. If it not done properly, it may cause more harm than if you just leave them alone.
