Well, some people on here take algin, which is suppose to help mop/absorb mercury inside a person. You can also knock out all the foods that make a mercury toxic person far worse, which is sugar, gluten and yeast, plus possibly even natural sugar foods like fruit and milk temporarily.

Supplements that can help are vitamin C (get a good powdered one), vitamin B complex, zinc, magnesium, vitamin E, and possibly selenium and milk thistle.

And making sure you have a lot of good fats too, as well as protein. Fats to have are extra virgin olive oil, organic coconut oil, and butter. you can use these in cooking and/or on your foods. Plus healthy fish oils (mercury free, a good brand is blue ice and a good fish oil from them is the cod liver oil and taking about a teaspoon a day).

Eating things like meat and eggs and healthy vegetables are good too. Excluding potatoes, as they are high in natural sugar. But depending on how far you wish to go to lessen your toxins and possible yeast.

The body will usually have a candida problem in any immune/toxic condition. This can be very bad and can even cause many of the same symptoms as mercury and even overtake it in some cases. This is why anybody should try and follow a candida diet. problem is, most people cannot stay the course and keep cheating or give up too early and do not get results. You will only get results if you stick with it and do not cheat, but it can take a while to improve and some get a little worse temporarily as the toxins start to come out of you.

I wish I could give more suggestions to you, but sometimes the simplest are the best (diet and supplements). Anything else may not be wise as it could just be too overwhelming to you.
