Hi, yeah it's safe to take selenium and a good idea, as mercury depeltes selenium in the body. Selenium also competes with mercury for binding sites, and can also neutralise some of the effects of mercury and as far as I know, selenium helps the body produce glutathione, which helps with detoxification. Although it does not directly chelate mercury.

Just a note on the hair analysis. Testing for mercury is notoriously confusing. The hair analysis test has to be read correctly because the level of mercury might appear low to very low, yet you may have a LOAD of it in you, but you are not excreting it. You may show a high level of mercury, which would mean you may be poisoned, but your body is able to eliminate it. Sometimes the way to find out if you are poisoned with a hair analysis test, is to look at the minerals etc that mercury has the ability to deplete in the body.

I would suggest that you could go to a site called frequent dose chelation and even put up your hair analysis results and people there can also help with interpreting whether mercury is playing a role in your health problems by what minerals are depleted etc.

Many doctors assume a low/to very low level of mercury automatically means you are not poisoned by it, they do not take into consideration retention toxicity, or the fact that the mercury is hidden or mainly in the brain etc. They do not look at the mineral status and find out which minerals mercury intefers with. So it's really hard to find a doctor or health professional that understands the way to read the hair testing and the way mercury works.

Not that I know much, but I have learned a bit over the years from having low hair results and understanding that it can actually be a very bad sign if you're retaining mercury and not excreting it properly.

But if I were you, I'd take Vitamin C, vitamin E, selenium (don't take Vitamin C with selenium, take it 2 hours away from it, as it can interfere) and probably a multvitamin/mineral, and algin to help cope easier, and i'd eliminate sugar, yeast and gluten out of my diet, which helps rid you of excess candida and strengthens your immune system.

Just a suggestion though.
