Instead of looking at reviews (waste of time),
-learn how fish oil interacts with the body
- What oxidation and degradation is with respect to fish oil
- IVO / IFOS certification
- Manufacturing process
- Third party testing
Then you will be know how to shop for fish oil (and all supplements by extension). If you can't do that, then stop buying supplements because you are wasting your money being uneducated.
Salmon or any fish really 2-3x per week. Problem solved.
