Omega-3 fatty acids are types of fat that must be obtained from dietary sources. Omega 3s are important for decreasing inflammation in the body and supporting optimum cell membrane function. They also prevent oxidation of cholesterol and platelet aggregation, important factors for maintaining optimal blood flow. Fish, seafood, and vegetables are good sources of omega-3 fatty acids, but taking supplements ensures adequate blood levels of omega 3s. The most beneficial omega-3 fatty acids, EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid), come exclusively from marine sources. Both fish oil and krill oil are good sources of DHA and EPA. Krill oil contains astaxanthin, a potent antioxidant. While flax oil does provide health benefits, it takes very large amounts of flax oil to raise omega 3 blood levels.
Suggested Dosage: Molecularly distilled fish oil, 1-4 grams 1000-4000 mg daily, or krill oil, 500-3000 mg daily. Krill oil occurs as a phospholipid (instead of a triglyceride like fish oil), which is easily absorbed through the intestines and more easily utilized by the body. Therefore lower doses are required.
Side effects: Omega-3 fatty acids thin blood. If you are taking blood thinners or have a bleeding or clotting disorder, discuss taking fish or krill oil supplements with your doctor. Avoid krill or fish oil supplements if you have shellfish or fish allergies.
