For people who are mercury toxic, ALA can cause a lot of symptoms to occur because of it's chelating properties.

Personally, I chose not to use it when I was mercury toxic and preferred to detox the lower body using chlorella and exercise.

For those who can take it, I would definitely start with low doses and work your way up over time.

Of course, in today's world, it's virtually impossible to avoid exposure to mercury and other toxins because of chemtrail operations.
