Because of their benefits for heart, brain, eye, and immune health, omega-3 fatty acids are an essential part of a healthy diet. However, consuming too much of these fatty acids can be harmful.
Because the body cannot synthesize omega-3 fatty acids, it must supplement them through foods rich in omega-3, such as salmon, tuna, mackerel, flaxseeds or chia seeds. In addition, taking omega-3 pills is also a way to supplement enough of these fatty acids for the body, according to the health website Medical News Today (UK).
Omega-3 fatty acids are good for your health, but too much can be harmful
Taking too much omega-3 fatty acids can lead to the following side effects:
Too much omega-3 fatty acids increases the risk of bleeding
Adding omega-3 fatty acids to your daily diet is safe and beneficial. However, taking too much can increase your risk of bleeding, especially when taking high doses of fish oil supplements. This is because omega-3 fatty acids act as a natural anticoagulant. High doses of this nutrient can interfere with platelet activity, which can impair blood clotting.
Atrial fibrillation
Atrial fibrillation is another serious side effect of taking too many omega-3 fatty acid supplements. This condition can cause an irregular heartbeat, increasing the risk of blood clots, stroke, and heart failure.
Digestive problems
According to the National Institutes of Health (USA), taking omega-3 fatty acid supplements can sometimes cause some digestive discomfort, such as heartburn, nausea, and diarrhea. The reason is that omega-3 has a mild laxative effect and is high in fat, so it can sometimes cause discomfort.
To reduce this problem, experts recommend that people start with a low dose and gradually increase it over time as their bodies adjust. Taking omega-3 supplements with meals will improve digestion and reduce the risk of heartburn.
Immune effects
Omega-3 fatty acids support immune health by reducing inflammation, strengthening cell membranes, and promoting immune cell activity. However, too much omega-3 fatty acids can impair immune response.
The National Institutes of Health recommends consuming only 1.1 to 1.6 grams of omega-3s per day. If you eat fish, the American Heart Association recommends eating only two servings of fish per week, with a serving size of 85 to 110 grams, according to Medical News Today .
