Fish Oil and AFIB

Posted by beebo @beebo, Jan 3, 2025

I’ve had various levels of AFIB for quite some time and I’m currently not having any issues or problems since most recent ablation.
I have been taking fish oil supplements, but now I’m hearing that it might be a trigger for AFIB. I guess I should stop taking them but I’d like to hear any advice from here about that. Thanks

@gloaming the issue of EFAs and omega balance is incredibly important, and complex, and needs far more research!

I just wanted to throw in that there is some chatter that you may want to limit the polyunsaturated fats, and that even some saturated fats may be harmless or even beneficial especially shorter-chain versions like coconut oil.

The thing about fish oil, and this may be involved in the issue with afib, is that most people need more omega-3 in order to establish the right balance with omega-6, that we all tend to over-consume these days, and further that some omega-9, most available in extra virgin olive oil (EVOO), needs to be in the balance, too. But there are endless varieties of each of these omegas and it just gets crazy. Yet these factors all have to be controlled, and they seldom are, or any study is going to be virtually meaningless.

It also turns out there are at least three ways to prepare fish oil supplements, as esters, as triglycerides, and as lysophospholipid, and ... etc. In natural sources they tend to the latter two. The absorption and delivery past the blood-brain barrier vary greatly. Plus, you may want to make sure your diet (or supplements) include the basic omega-3 ALA, as well as the fish oil, in any nutrition plan.

@carbcounter Thanks! Yes, it's a complex subject, changing all the time, and it's hard for the typical person to keep up. I appreciate your knowledge and your ability to communicate it.

John Mandrola, an EP who does a great blog for physicians, talks about fish oil pills this week and last week. His opinion is fish is good, fish pills probably not good for afib. He goes through why.

Does he have a web site to go on. Or how do you his blog.

I take 2000 mg of Fish Oil twice a day. It is to reduce my triglycerides which it did by 50%.

I have a Mayo EP that knows I am on Fish Oil and has made no notification or concern about being on it. Nor has my PCP.

I know my wife was on a prescription form of Fish Oil but her PCP said she could take OTC fish oil.
