Fish oil is known to lower triglycerides, but can it prevent a heart attack?

Again, we see the scams perpetrated by the OTC vitamin companies. Over-the-counter fish oil capsules are usually 300 milligrams of eicosopentanoic acid (EPA) and docosohexanoic acid (DHA) each; the dosage needed to reduce triglycerides is over 3,000 milligrams of EPA and DHA, or greater than 10 capsules. Researchers are using a highly purified form of fish oil made only of EPA.
