I take Carlson's fish oil. I like Carlson as a company, and their fish oil - and mercury testing - is rated very high quality.
You who know from my posts that I used to be a research chemist also know that I am very conservative about the chemicals I put in my body. Carlson's meets my criteria.
Btw, it should be noted that fish oil is different from cod liver oil. Much less vitamin a to worry about.
