What are the benefits of taking omegaThere's strong evidence that omega-3 fatty acids can significantly reduce blood triglyceride levels. There also appears to be a slight improvement in high-density lipoprotein (HDL, or "good") cholesterol, although an increase in levels of low-density lipoprotein (LDL, or "bad") cholesterol also was observed.
When should I take omegaSummary. Some evidence suggests that taking supplements that contain omega-3 with a meal that contains fat can increase absorption. As a result, people may wish to take fish oil at breakfast, lunch, or dinner. However, there is no correct or incorrect time to take it.
What happens if you take omegaWhen taken by mouth: Fish oil is likely safe for most people in doses of 3 grams or less daily. Taking more than 3 grams daily might increase the chance of bleeding. Fish oil side effects include heartburn, loose stools, and nosebleeds. Taking fish oil supplements with meals or freezing them can reduce these issues.
What organs benefit from omegaThe omega-3 fatty acids in fish are good for the heart. Find out why the heart-healthy benefits of eating fish usually outweigh any risks. If you're worried about your heart health, eating at least two servings of fish a week could reduce the risk of heart disease.
