Fish Oil Caution: Health Experts Reveal 7 Risks To Consider

In the pursuit of overall wellness, many people turn to fish oil supplements for their numerous health benefits, such as improving heart health, reducing inflammation, and boosting brain power. However, it’s crucial to understand potential risks associated with these supplements. “Fish oil provides omega-3 fatty acids, which offer important health benefits—but like any supplement, fish oil does come with some potential risks,” warns Farhan Malik, MD. Today we delve into the seven hidden dangers of taking fish oil supplements, shedding light on the side effects one should consider before embarking on this wellness journey.

1. Potential for Increased Bleeding

Fish oil supplements can interfere with blood clotting. This effect is particularly noticeable when you exceed the recommended dosage. “Excessive amounts of fish oil can actually lead to bleeding problems,” Malik mentions. He reports witnessing nosebleeds or bruising from extremely high doses of fish oil in his practice.

2. Gastrointestinal Upset

Dr. Jennie Stanford warns that fish oil supplements could have undesirable effects on those with a sensitive gastrointestinal system. “In some people, fish oil supplements may cause nausea, diarrhea, bloating, or belching with a fishy aftertaste,” she explains. Using coated fish oil tablets and taking them with meals could reduce these effects.

3. Impact on Blood Sugar Regulation

While fish oil supplements can improve glycemic control for many people, they may alter the effects of glucose-lowering medications. Stanford cautions, “This makes it necessary to monitor blood glucose closely for hypoglycemia and to adjust medication doses accordingly.”

4. Interaction with Certain Medications

Fish oil supplements could interact with blood-thinning and antiplatelet medications, increasing the blood-thinning effect and raising the risk of adverse bleeding. Stanford comments, “With medications like aspirin, clopidogrel (Plavix), warfarin (Coumadin), and other anticoagulant medications, adding fish oil supplementation can increase the blood-thinning effect and elevate the risk of adverse bleeding.”

5. Risk of Atrial Fibrillation and Stroke

There’s conflicting research concerning the risk of atrial fibrillation and stroke in relation to fish oil supplements. “Many studies suggest that taking fish oil supplements may increase the risk that healthy individuals develop atrial fibrillation and then subsequent stroke,” states Stanford.

6. Risk of Rancidity and Oxidation

Dr. Malik cautions that fish oil supplements could go rancid over time or even become oxidized, thus losing their health benefits and potentially producing harmful byproducts. He recommends checking the freshness of the capsules and storing them in the refrigerator to avoid consuming rancid supplements.

7. Possibility of Contamination

Taking fish oil supplements to escape consuming high mercury levels in fish may not be as safe as it seems. According to Malik, fish oil supplements can still harbor toxins if the oil is not properly purified and decontaminated.

With these seven potential risks in mind, it’s clear that embarking on a fish oil supplement regimen should be done thoughtfully and ideally with medical guidance. “Always be cautious about dosage and freshness when taking fish oil. Moderation and paying attention to quality is key,” asserts Dr. Malik. Remember, knowledge equips you to make informed decisions about your health and wellbeing.
