Omega 3 fatty acids

Omega 3 is a popular supplement available in the form of fish liver oil capsules extracted from fatty fish like salmons and sardines. According to a latest research, about 19 million people in the USA consume some kind of omega 3 supplements daily.

The reason behind this popularity is that these omega 3s are very beneficial for many important brain functions. It is believed that the people who take some sort of omega 3 supplements have a low risk of suffering from cognitive disorders. High blood levels of omega 3 are linked with improved brain structure and cognitive functions.

This article will summarize everything you need to know about Omega 3 fatty acids, how they work, and their effects as a brain stimulant in consumers. So, let’s hop right in.

What are Omega 3 fatty acids?


These are essential extraneous fats, which means that our body needs them but cannot make them on its own. These play a vital role in cell membrane formation and are essential for generating a few hormones in the body. There are three categories of these fatty acids;

How do they work?


While omega-3 fatty acids’ benefits can no longer be denied, their cellular mechanism of action remains elusive. The omega-3 fatty acids action is a complex phenomenon and involves several signaling pathways. Here are a few theories on some of the possible cellular mechanisms by which the omega 3 fatty acids may function.

These polyunsaturated fatty acids play multiple roles. Therefore, they are likely to act through different mechanisms. There are 4 possible mechanisms by which omega 3s can act in a cell or tissue to perform their physiological actions:

Brain benefits of omega 3


Polyunsaturated fatty acids have a wide range of brain functions, right from brain development to its processing. Several studies show that the omega 3 fatty acids work as a nootropics agent because they provide neuron-protection to our brain cells and their cell membranes and reduce the damage due to free radicals.

Also, by consuming the omega 3 supplements, you will experience improvement in brain functioning within weeks. It also helps delay the onset of some mental disorders that are age-related and run in your family, such as Alzheimer’s disease.

Research has proven that in the last three months of fetal development, Omega-3s are supplied to the fetus to meet the demands of rapid brain growth, and that premature infants have less brain volume and do not suffer from brain abnormalities. Testing kids whose mothers consumed omega 3 supplements during pregnancy revealed significant differences in their IQ, memory skills, communication, and social behavior.

If the diet of children aged between 6 to 12 years is rich in omega 3, it will result in improved learning skills and improved cognitive ability.

Other studies reveal that kids who had been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) had lower levels of Omega-3s in their blood, and taking an omega 3 supplement led to a visible improvement.

Our brain cell membranes pass through a natural deterioration process with age, and it is a major cause of developing age-related dementia and cognitive decline. But a few studies have shown that taking Omega-3 supplements can delay this process in some people. Since it has anti-oxidative and anti-inflammatory properties, people with sufficient Omega-3 levels in the blood have increased blood flow to their brains and have better cognitive skills than those with lower levels.

Research has indicated that intake of Omega-3s may be an effective treatment tool for mood swings and depression. This theory has been supported by some epidemiological studies, showing that people who eat more seafood have fewer chances of depression. It also helps to reduce the secretion of stress hormones, which cause depression and stress in people.

Daily Dose and Precautions


Consuming 1000-2000 mg of omega-3 fatty acids from a supplement per day is a safe place to start. Your dose should never exceed 3000 mg per day.

You should also consult your physician before starting its use if you are pregnant or have any other health concerns.

The Bottom Line


Omega-3 fatty acids are necessary for normal brain development and function. It also helps to boost your mental health and delay age-related dementia. People with depression or a mild decline in cognitive function should consider taking an omega-3 supplement. They will experience a significant improvement within a few weeks.
