You can take just about anything alongside chelating, it does not interfere with it at all. The only danger is how they affect you? and are they safe in respect to the mercury itself? Some supplements can stir the mercury up quite wildly and worsen symptoms dramatically and sometimes long term.

So you have to cautious. People on here have sometimes had adverse reactions to garlic supplements , amino acid supplements, cilantro, chlorella, msm , etc... however, some do well. So it's really a very individual thing, but no they will not interefere with the chelation, you can take supplements the entire time.

I personally dont hear great things about soy and choose not to take it. I steer clear of things like gluten grains, wheat, sugar, honey, milk, too much fruit, soy, yeast, etc. Those things tend to cause issues in people with mercury because so often they have a yeast overgrowth which can cause intolerances to many foods, not to mention they feed the yeast also.

Healthy fats are very beneficial by the way, especially to someone with mercury toxicity. They aid healing, encourage bile flow, and especially for brain healing. So dont shy away from the good fats like butter, organic virgn coconut oil, extra virgin olive oil, lard, cod liver oil (make sure mercury free) etc. Far from gaining weight, they often aid losing weight because they give the body what it needs and help satiate the appetite, provide energy, good for the skin, eyes, hair, brain etc..

On the other hand, the bad fats like hardened vegetable oils cannot even be properly utilised by the body and are toxic. trans fats etc, stay away from.

Animal fats, plus coconut and olive oils are extremely good. Here is a link you may find interesting and surprising
