According to a new study by Harvard scientists, Omega-3 fatty acids in fish oil seem to keep the heart in good working order by preventing a type of irregular heart beat known as atrial fibrillation. Irregular heart rhythm can be a threat to your health but according to a new study published in the science journal Circulation, people with high levels of omega-3 fatty acids in their blood have up to 30 per cent lower risk of atrial fibrillation compared with people who have low levels of these fatty acids. Atrial fibrillation is the most common type of irregular heart beat and is typically associated with palpitations, fainting, chest pain, or congestive heart failure. It can increase the risk of stroke by up to seven times that of the average population. Fish or capsules? Oily fish like salmon, herring, and mackerel are excellent omega-3 sources whilst Bio-Marine Plus is an alternative for those who do not like the taste of fish. Bio Marine Plus supplement provides purified (PureMax-certified) fish oil in the form of free fatty acids that are highly bio-available. Bio-Marine Plus also contains vitamins B12 and folic acid, which help to control levels of homocysteine, a natural compound that is linked to an increased risk of atherosclerosis. PureMax is considered to be the world’s leading technology for purifying fish oils. It guarantees levels of pollutants that are far lower than the official threshold values set by health authorities.
