(HealthDay News) — Omega-3 fatty acids are essential elements that the body doesn’t make on its own, says the Cleveland Clinic. Fish, plants and supplements are among the best sources of omega-3 fatty acids.

For people who don’t have a history of heart disease, two servings of fish per week is recommended. Research indicates that omega-3 fatty acids can help improve your cardiovascular health.

But don’t overdo it. Consuming three or more grams of omega-3 fatty acids each day can have negative health effects, the clinic says.
