Independent testing by a White Plains, NY firm,, has found that 7 of 24 fish oil supplements tested exhibited quality problems.  Some products exhibited multiple issues.

  • Three products contained less of the omega 3 fatty acids EPA and/or DHA than claimed,
  • Three product were spoiled (including a children’s supplement)
  • One enteric-coated product released its ingredients too early
  • One supplement for pets exceeded the contamination limit for PCBs.

We recommend fish oil supplements highly because their Omega-3 fatty acids help improve circulation, integrity of blood vessels, proper brain functioning, flexibility and permeability of cell membranes, and helps protect the retina’s photoreceptor cells.  They help to prevent and treat such conditions as glaucoma and macular degeneration.
