If you can’t get enough fish oil from your diet, try fish-oil capsules. For fighting heart disease, I recommend 1,000 mg coming from a combination of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), the two most beneficial types of omega-3 fats. Because the amount of EPA+DHA per capsule varies widely among brands, you’ll need to read the label and add up the individual milligrams yourself to determine how many pills it will take to reach 1,000 mg total EPA+DHA. Store these supplements in the fridge to keep them from going rancid. To prevent fishy burps, take with food and choose enteric-coated varieties, which are designed to dissolve in the intestines instead of the stomach. Because fish oil acts as a blood thinner, it should not be taken by people who have hemophilia, platelet disorders, or who are already taking blood-thinning medications or aspirin. People with diabetes should always talk with their doctors before popping fish oil supplements.
