Although there are 11 types of Omega-3, three of them are vital for human health and growth. They are as follows: ALA (Alpha-Linolenic Acid), DHA (Docosahexaenoic Acid), and EPA (Eicosapentaenoic Acid).

ALA is derived from plants like flaxseed, soybean, and canola. DHA and EPA are obtained from seafood like fish.

Three common types of capsules are:

Fish Oils

Fish Oil Supplement

Fish oils are one of the most widely used omega-3 supplements. It has high concentrations of omega-3.

Processed Fish Oil

Sometimes during refining, the triglycerides present in fish oil is converted into ester like ethyl ester. The extra step ensures that you get purified or concentrated fish oil. The concentration of the oil can also increase the levels of EPA and DHA. Indeed, some oils may contain 50 per cent to 90 per cent pure EPA or DHA.

Purification has added benefits because it removes contaminants from the oil, such as mercury.

Neuroprotective Action

Did you know that ALA is a fantastic antioxidant? Oxidative stress can cause DNA damage and, as a result, neuronal death.

Study findings suggest that taking omega-3 supplements can reduce seizures experienced by people with epilepsy.

According to research, ALA can increase the expression of a DNA repair protein known as PCNA (Proliferating Cell Nuclear Antigen). As a result, it protects neurons from neurotoxicity and can thus treat Parkinson’s disease.


Sleep Quality

Don’t we all love our sleep time? After all, one of the pillars of good health is adequate sleep. Lack of DHA reduces the production of melatonin, which is involved in regulating sleep and waking cycles.

Side Effects Of Omega 3

A high dose of fish oil may cause more harm than good, and taking too much may worsen your health. Here are four possible side effects of consuming too much omega-3 fatty acids or fish oil.

High Blood Sugar

Reduce Blood Clotting

It is possible that large quantities of fish oil inhibit blood clot formation and thereby increase bleeding risk and cause symptoms such as nosebleeds and bleeding gums.



The main disadvantage of some omega-3 fatty acid supplements, such as cod liver oil, is that they contain a lot of vitamin A!


Gastric Reflux
