What bottles of complement do you see when you open your medicine cabinet? Maybe you have fish oil to reduce the risk ofcardiopathy, probiotics forintestinal health maintenance and vitamin D for aStrong immune system. According to new research, thoseFish oil pills can actually be a waste of money.

A new study conducted by scientists from the University of Georgia suggests that daily fish oil can only be effective if you have the right genetic makeup. The study, which was published in the newspaperPlosGeneticIncludes data of 70,000 participating in a large-scale cohort study called U.K. Biobank, which collected genetic information and health of 500,000 participants.

In the sample, researchers have examined four blood lipicides - high density lipoprotein (HDL, high density cholesterol), low density lipoprotein (LDL, unhealthy cholesterol), total cholesterol and triglycerides - all are biomarkers for cardiac disease. The most shocking discovery was that a fish supplement canIncrease the risk of heart diseasein some individuals. (In touch:The 7 healthiest foods to eat right now)

"We have known for a few decades, a higher level of omega-3 fatty acids in the blood is associated with a lower risk of heart disease," Kaixiong Ye, author of principal studies and assistant professor of genetics in the Franklin College of Arts and Sciences,said in a statement.

"What we found is thatFish oil supplementation is not good for everyone; It depends on your genotype, "Ye added." If you have a specific genetic background, fish oil supplementation will help reduce your triglycerides. But if you do not have this good genotype,Take a fish oil supplement actually increases your triglycerides. "

The data sample was divided into two groups: those who took fish oil supplements (which were about 11,000) and those who did not do it. The researchers then conducted a genome-wide analysis for each group, which involved tests of 8 million genetic variants. Sixty-four million tests later, the results showed a significant genetic variant in the GJB2 gene. Those who took fish oil and that Genotype AG had a decrease in their triglyceride levels, whilePeople with AA genotype who took the supplement had a slight increase in their levels.

Previous clinical trials have indicated that fish oil is not effective atPrevent heart disease, May you think you may have to do with the lack of genotype consideration. But this new study identified a specific gene that can modify a person's response to fish oil supplementation.

"Customizing and optimizing fish oil supplementation recommendations based on a person's unique genetic composition can improve our understanding of nutrition," said YE in the press release "and lead to significant improvements in health and human well-being ".

In the meantime, why not stick to incorporate more hearty fish such as salmon and mackerel in your diet one or twice a week? Your heart could benefit from omega-3 fatty acids rich in these food sources. For more, be sure to readThese two supplements can reduce your risk of heart disease, a new study indicates.
