Fish oil is widely known as a product that is exceptionally beneficial for maintaining heart health, blood vessel elasticity, and cognitive function. It is often recommended to people who have blood pressure problems, experience weakness and fatigue, have difficulty concentrating, or suffer from absent-mindedness and forgetfulness.<\/p>\n\n\n\n

However, recent scientific research has shown that fish oil is far from being a \u00absuperfood\u00bb and may not even be the best source of the omega-3 fatty acids the human body needs for proper and healthy functioning.<\/p>\n\n\n\n

The secret behind fish oil\u2019s popularity<\/h2>\n\n\n

The popularization of fish oil began in the 1970s, when scientists J\u00f8rn Dyerberg and Hans Olaf Bang studied the health of the indigenous people of Greenland. They noted that, unlike most residents of Denmark, Greenlanders rarely suffered from ischemic heart disease, tachycardia, bradycardia, and other similar cardiovascular conditions.<\/p>\n\n\n\n

Research showed that Greenlanders had elevated levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in their blood. The scientists suggested that these substances might be responsible for protecting the cardiovascular system.<\/p>\n\n\n\n

An experiment conducted by Hussein Yassine, a researcher at the Keck School of Medicine, showed that fish oil contained in dietary supplements is not necessarily an effective source of unsaturated fatty acids and therefore may not provide the expected protection against cardiovascular disease.<\/p>\n\n\n\n

Research conducted by Professor Rajesh Subbiah also showed that regularly taking fish oil in capsule form does not necessarily increase omega-3 levels in the human body.<\/p>\n\n\n\n

As a result, scientists have increasingly come to believe in recent years that the health benefits of dietary supplements \u2014 including fish oil \u2014 and their effectiveness in preventing many diseases may have been significantly overestimated.<\/p>\n\n\n\n

In addition, inexpensive raw materials of questionable quality are sometimes used to produce encapsulated fish oil. Prolonged and\/or improper storage of dietary supplements can cause omega-3 fatty acids to oxidize, potentially making the product not only ineffective but also harmful to the body.<\/p>\n\n\n\n

What to consume to replenish fatty acid levels<\/h2>\n\n\n\n

Some of the best sources of EPA and DHA are marine algae, particularly kelp, as well as microalgae. Flax seeds and unrefined flaxseed oil<\/a> are exceptionally rich in alpha-linolenic acid (ALA), which is also known as an omega-3 fatty acid. One tablespoon of flaxseed oil contains approximately 7 grams of ALA.<\/p>\n\n\n\n

In the human body, ALA can be converted into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are involved in numerous metabolic processes.<\/p>\n\n\n\n

Flaxseed oil<\/a> and flax seeds also contain lignans \u2014 plant compounds (polyphenols) with antioxidant properties that are important for various biological processes, including hormone metabolism.<\/p>\n\n\n\n
