The expert warned about the negative consequences of excessive consumption of omega-3

Excessive consumption of omega-3 can lead to side effects, said Dmitry Gurov, head of the Sberbank Pharmacy. At the same time, analysts of the Rambler&Co media holding and Sberbank found out how often Russians take such polyunsaturated fatty acids, and told Izvestia about the results of the study on March 13.

"Excessive consumption of omega-3 fatty acids can lead to side effects such as upset stomach and other effects on the body. Too low a dosage will not have a noticeable effect," Gurov said.

He clarified that not all combinations of omega-3 with other vitamins are beneficial. For example, when the drug is combined with vitamin K, the risk of bleeding increases, since omega-3 thins the blood, and vitamin K promotes its clotting.
