Good question! Where mercury & other poisons are concerned, it's my opinion that unless you go really crazy (like 20 caps a day), more is better. I know that is a strong statement, but in this case I believe it. As far as I can figure, algin does not contain anything harsh.

I am planning to buy a milk thistle product that is combined with other liver herbs, including turmeric.

Animals feel pain & suffering just as we do, and they value their lives as much as we value ours.
