Interaction among Omega 3, Ezetimibe and HDL

Ezetimibe is known to reduce absorption of Omega 3 fatty acids. That made me wonder whether I should keep taking it. But I had a new thought about all this and would welcome inputs.

My HDL has always been very high. For years I have been eating salmon every week and taking large-ish doses of EPA/DHA. But I assumed the sky-high HDL (it was 125) was mostly genetic.

After months on Repatha + Ezetimibe, all lipids were way down. And HDL was down to 114 – still sky high, but down.

So now I am thinking – not to worry about Ezetimibe blocking the EPA/DHA – may-be that (together with the salmon) is what is partly what’s driving the HDL. Perhaps I should even reduce the amount of EPA/DHA that I am taking. And restart a bit of the stanols.

This group has been so helpful to me in my efforts to hone my protocol.
Thank you

Ezetimibe is generally known to raise HDL though?

Currently waiting for my Omega 3 Quant test results. Lab received the sample, results should be available within a week. I’ve been on ezetimibe for well over a decade, current n-3 intake is low dose daily krill oil, also 1/4 cup walnuts and 1 tablespoon ground flax in morning smoothie and occasional salmon for dinner.

That will be an extremely interesting test result. I have recently paused Ezetimibe because of concerns over Omega 3 absorption.

I try to keep at least an 18 hour gap after taking Ezetimibe and consuming anything with ALA/EPA/DHA and vitamin K.
It’s the best way I can think of doing it if taking Ezetimibe daily.

Do you have any mimimum time between omega 3 intake and ezetimibe? I have used to wait 3 hours, eating fat fish around 7 pm and ezetimibe around 10 pm. If chat gpt is to be trusted (no time for anything more) “Fatty fish can take a few hours to be fully digested and for its nutrients, including omega-3 fatty acids, to be absorbed. A safe window to wait might be 2-3 hours post-meal, but this can vary based on the amount of fish consumed and individual digestion rates”.

With one meal a day I eat a huge portion of fat fish. Stimulated by this thread I will increase the safety margin by putting my ezetimibe next to my floss for intake just prior to bed time.

Plus will have an omega 3 test to check.

This forum is great.

I don’t think that measures alpha-linolenic acid, which probably has benefits outside of weak conversion to EPA and DHA, and ALA is what ezetimibe might block. I don’t think anyone has suggested it blocks EPA and DHA.

There is indeed a study floating around on one of these threads strongly suggesting it blocks EPA/DHA absorption.

(Edit: no there isn’t)

Link? A fast search doesn’t find it…

Oops you’re right – I was thinking about the ALA study. I actually found another pilot study that specifically found ezetimibe does not block absorption of EPA:

It may, however, inhibit vitamin E absorption:

Thanks! I’d been looking for a study. That matches up with what users here, @Joseph_Lavelle , have been reporting.

I wonder if this would work for ALA as well? Seems like it should.

I take ezetimibe in AM. I take fish oil in AM and PM, and I eat fish most nights. So I mostly used the 4 hours gap or more. My omega index was 12%
