Dr. Mercola supplements, graded by the human studies
We graded 2 Dr. Mercola products against the human studies of their ingredients, the dose on each label and what buyers say in their reviews. Each grade belongs to the product and the goal it was graded for: we do not grade how Dr. Mercola makes, tests or sells its products, and we sell no supplements. Educational, not medical advice.
