Study Leads To Dosage Recommendations For Omega-3 Fatty Acids

Searching for the best dose of docosahexaenoic acid (DHA), an essential omega-3 fatty acid, researchers from France have established that 200 mg per day is sufficient to boost heart health in men.
The scientists enrolled 12 healthy men aged between 53 and 65 years to investigate the effects of different doses of DHA, including 200, 400, 800 and 1,600 mg per day. The participants spent two weeks consuming each dose amount.
After the end of the two weeks, the researchers analyzed the men’s blood and urine samples which showed that the biochemical markers that predict cardiovascular problems — such as those related to aging, atherosclerosis and diabetes — were affected already at the lowest dose.
Michel Lagarde, co-author of the study, explains that the study shows a regular consumption of small amounts of DHA is likely to improve individuals’ health status, especially in regards to cardiovascular and circulation functions.
Among the best sources of omega-3 fatty acids are oily fish such as salmon and mackerel, but they can also be obtained from dietary supplements like krill or fish oil.
