On Nov. 15, the Hong Kong Consumer Council announced the test results of 25 samples of fish oil supplements and found that all fish oils contained various levels of contaminants.
It also found that in many of those samples, the content of omega-3 fatty acids, including DHA (good for the brain, heart, and eyes) and EPA (supports the immune system), can be lower than they are claimed by 83 percent and 31.7 percent, respectively.
3-MCPD Found in 95 Percent of the Samples
The test also found that one contaminant, 3-monochloropropanediol (3-MCPD), which may cause damage to the kidneys and the central nervous system and affect the male reproductive system if taken in higher amounts, was contained in more than 95 percent (24 types) of fish oil samples. The following three samples were found to exceed the EU upper limit of 2,500 mcg/kg (micrograms/kilogram):- GNC Super Fish Oil (180 capsules package): 6,800 mcg/kg.
- Adrien Gagnon Heart Health Extra Strength Omega 3: 15,000 mcg/kg.
