With respect to CVS Krill Oil, the study found it only contained 60% of the 300mg of Omega-3 Krill Oil represented
The objective of the underlying study was to assess EPA and DHA label declarations of fish, krill, and algal oil dietary supplements in the USA. The researchers concluded that the quality of fish oil supplements is not being adequately monitored by manufacturers or government agencies.
A number of other krill oil manufacturers were implicated in short changing consumers. Also included as a defendant was the manufacturer of the krill oil for CVS, LANG PHARMA NUTRITION.
