Omega-3 fatty acids, often known as omega-3 oils, are polyunsaturated fatty acids (PUFAs) that play critical roles in the body’s functioning. They are abundant in nature and significantly impact human physiology and diet.

There are three distinct kinds of omega-3 fatty acids, which may consist of:

• ALA or Alpha-linolenic acid is found predominantly in vegetable oils such as flaxseed, soybean, and canola. The human body mainly utilizes ALA from food for energy, with minimal conversion to EPA and DHA.
• Eicosapentaenoic acid (EPA) – discovered in algae and seafood, mainly fish.
• Docosahexaenoic acid (DHA) – predominantly seen in algae and fishes.

Omega-3s work in the body in several ways

• Omega 3 is needed for the proper cellular function in the body.
• They play a crucial role in producing and supporting cellular connections in our cell membranes.
• They act as a precursor in synthesizing hormones that regulate blood clotting, blood vessel wall relaxation and contraction, and inflammation.
• Gives the body energy and promotes the health of numerous bodily systems.
• While essential to all of our cells, the cells in our brains and eyes contain a lot of omega-3s.

The following food sources and dietary supplements both include omega-3 fatty acids:

Food sources

• People can boost their omega-3 consumption by eating more particular types of seafood, seeds, and nuts.
• Seafood, particularly cold-water fatty fish like sardines, herring, tuna, and salmon.
• Seeds and nuts such as flaxseeds, chia seeds, and walnuts.
• Oils from a plant source, such as flaxseed, canola, and soybean oils.
• Fortified foods include some milk varieties, yogurt, newborn formula, soy drinks, and eggs.

• Scaly, dry skin.
