What health agencies say

An opinion says what the agency recommends; it is not a rule binding on the product.

The BfR recommends that people taking blood pressure lowering drugs or coumarin-type anticoagulants seek medical advice before taking more than 100 mg of coenzyme Q10 per day, as possible interactions have not been sufficiently studied.
