Despite the various benefits that fish oil is said to offer as a supplement, medical experts still suggest caution in overusing it. There have been studies that indicate certain risks associated with fish oil. In some studies, there are suspected risks that researchers have found in the use of EPA and DHA fatty acids in fish oil.
Over usage of EPA and DHA, which is determined at more than three grams daily, are known to increase the risk of bleeding, especially in people who are also taking aspirin or warfarin. But further research may be needed to determine if EPA and DHA do offer such risks. Extreme dosage intake of fish oil is also associated with a higher risk of experiencing hemorrhagic stroke. In some individuals, fish oil intake may also affect LDL cholesterol levels.
Because fish oil is still considered as fat, people with conditions arising from too much fat in their systems should also be cautious of taking fish oil as a supplement. Recent research seems to provide different results when it comes to how the fatty acids in fish oil affect people who may be suffering from heart disease or stroke.
In absence of definitive research, patients are being cautioned not to take fish oil without the recommendation from their doctor. People with certain heart problems or a history of heart disease should first talk with their doctors about the safety of taking fish oil supplements.
