Do brands of cheap fish oil contain high amounts of mercury? If so, what relatively inexpensive brand of fish oil would not have high amounts of mercury?
If the label doesn’t specifically say the oil has been purified/molecularly distilled, then it’s anyone’s guess.
If you look at the actual amount of EFA’s in Biotest Flameout it compares quite favorably costwise with any fishoil.
Plus it contains CLA.
