Omega-3 fatty acids like DHA, EPA and ALA are essential for the body's health, but cannot be naturally produced, so they must be consumed through supplementation or food. These acids help lower the risk of developing chronic illnesses like cancer, heart disease and arthritis, and are important for healthy brain function, states the University of Maryland Medical Center. Although these are healthy supplements, they can cause adverse effects in some people, so it is important to talk with your health care provider before increasing the amount of omega-3 fatty acids in your diet.
Step 1
Take a daily omega-3 fatty acid supplement. You can take one that contains 1 g of EPA and DHA if you have heart disease, states the University of Maryland Medical Center. Choose an omega-3 supplement that contains 2 to 4 g of EPA and DHA if you have high cholesterol levels. It may take several weeks before you experience any benefits from the supplement.
Step 2
Take your omega-3 supplements with a meal, as it can cause stomach upset in some people, states MayoClinic.com. Starting out with small doses and gradually increasing your omega-3 intake can also minimize stomach upset.
Step 3
Eat foods containing omega-3 fatty acids if you do not want to take supplements. Consume fatty fish like herring and mackerel, add flaxseed or flaxseed oil to your diet, or consume soybeans, pumpkin seeds and walnuts.
