Yes, the body does detox naturally with the support of vitamins, minerals and healthy living. But the main problem is the mercury in the nervous system. Vitamin C is the only known antioxidant to cross the blood brain barrier. But vit C only stirs things up in the brain area, it doesn't remove. So simply just using vits/ mins will not help those severely poisoned in the brain. This area can use up to 20 years to detox naturally. And that is only if there is no additional exposure to any metals adding to the build up. In our polluted world this is pretty unavoidable. ALA and cilantro (cilantro also removes aluminum and lead) removes mercury from the central nervous system. But should only be used in the tiniest amounts by anyone with this serious problem.
