I have also been taking fish oil supplements for years, but recently I have become aware of some possible problems concerning high levels of fish oil and atrial fibrillation. I strongly suggest that you search the terms fish oil and AFIB. I have cut down my dosage to one triple strength pill four times a week.
I never take the recommended dose on supplements. They’re supplements, not replacements. It saves me money long term by extending the life of the purchase, and I’m not literally pissing away physiologically unused product.
