Types of omega-3 fatty acids

There are more than one type of omega-3 fatty acids.

  • ALA:

    This form of omega-3 fatty acids is found in flaxseed, vegetable oils, dark leafy vegetables (spinach) and walnuts.

Our body converts a very small amount of ALA form of omega-3 fatty acids into EPA and DHA form. However, both these forms of omega-3 fatty acids have health benefits of their own.

Omega-3 fatty acids are the good fats and they are believed to fight against disease. They help by reducing the inflammation on overall body, including inflammation within the blood vessels and joints. They also help by lowering the risk of developing an abnormal heart rhythm, slows down the rate of plaque deposition on the inner walls of the blood vessels and also reduced the levels of unhealthy or bad fats in the blood flow.
