Major Study ever undertaken using meta-analysis involving 13 trials and more than 127,000 participants globally. Results endorsed by American Heart Association and published in the Journal Of American Heart Association.
The issue of whether
Omega-3 Fish Oil supplements could help in cardiovascular diseases have been debatable for many years with clinical studies that proved it did while there were also studies that said it did not. However, it is interesting to note that many of the studies that claimed it could not help in lowering the risk of heart attacks or cardiovascular diseases were smaller studies that often were indirectly funded by pharma companies and with PR companies enrolled to make huge coverages of these so called findings.
However, the matter is finally put to the rest with even the American Heart Association confirming the findings and concluding the facts. Individuals who received omega-3 fish oil supplements in randomized clinical trials had lower risks of heart attack and other cardiovascular disease (CVD) events compared with those who were given placebo, according to the new meta-analysis from Harvard T.H. Chan School of Public Health and Brigham and Women's Hospital. Researchers found an association between daily omega-3 supplementation and reduced risk of most CVD outcomes, including heart attack, death from coronary heart disease, and death from CVD. In addition, higher doses of omega-3 fish oil supplements appeared to provide even greater risk reduction.
First author Dr Yang Hu, a postdoctoral fellow in the Department of Nutrition at Harvard Chan School commented in an interview with
Thailand Medical News, "This meta-analysis provides the most up-to-date evidence regarding the effects of omega-3 supplementation on risk of multiple CVD outcomes. We found significant protective effects of daily omega-3 supplementation against most CVD outcome risks and the associations appeared to be in a dose-response manner."
In new study and analysis, the medical researchers did an updated meta-analysis that included three recently completed large-scale trials, which increased the sample size by 64%. The total population analyzed by Hu and colleagues included more than 120,000 adults in 13 randomized trials worldwide. The analysis included the VITAL trial, the largest randomized trial of omega-3s to date.
The results of the study showed that individuals who took daily
omega-3 fish oil supplements, compared with those who took a placebo, lowered their risk for most CVD outcome, including an 8% reduced risk for heart attack and coronary heart disease (CHD) death. The association was particularly evident at higher doses of omega-3 fish oil supplementation. This finding may suggest that marine omega-3 supplementation dosage above the 840 mg/day used in most randomized clinical trials may provide greater reductions in CVD risk. Given that several million people experience these CVD events worldwide each year, even small reductions in risk can translate into hundreds of thousands of heart attacks and CVD deaths avoided, according to the researchers from Harvard.
Senior author Dr JoAnn
Manson, chief of the Division of Preventive Medicine at Brigham and Women's Hospital and professor in the Department of Epidemiology at Harvard Chan School (She is also the Director of the large-scale VITAL trial of omega-3s.) further commented "Although public health recommendations should focus on increasing fish consumption, having an overall heart-healthy diet, being physically active, and having other healthy lifestyle practices, this study suggests that omega-3 supplementation may have a role in appropriate patients.”
Thailand Medical however recommends that when individuals are planning to purchase their
health supplements and Omega-3 Fish Oil Supplements, to do a bit of due diligence first. To begin with stay away from brands made in Asia as labelling laws here are very lax and most Asian manufacturers adulterate their supplements with other inferior constituents or worst the actual active ingredients are of a lower bioactive capability as they normally use cheaper sourced products that have no real health benefits though it can be labelled as Omega-3 Fish Oil supplements.
For a good brand of health supplements and Omega-3 Fish Oil Supplements, buy either the Now Brand or Life Extension brands from the US.
