Is Carlson's cod liver fish oil tested by the International Fish Oil Standards?
Reply: I just checked the IFOS website and I couldn't find any documented lab reports for any lab tests on Carlson's Cod Liver Oil.
Carlson Labs claims their fish oils are regularly tested using AOAC international protocols for potency and purity by an independent FDA Registered laboratory.
If you want this info, you could visit the Carlson Labs website; see if they have a Customer Service or Quality and Assurance Dept. and ask if they can send you a copy of any available lab reports on their cod liver oil. Good luck and I hope this information is helpful to you. ~ Kevin
