Celery and Fish Oil Triglycerides

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Fish Oil Triglycerides

Fish Oil Triglycerides falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Celery interacts with.

Theoretically, celery root might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
Celery root contains the constituents falcarinol and falcarindiol. Laboratory research suggests that these constituents can inhibit platelet aggregation. This effect has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with celery and Omegaven (fish oil triglycerides): both can have a mild blood-thinning leaning. Fish oil itself can make your platelets a little less sticky, and celery contains plant compounds (falcarinol and falcarindiol) that did the same thing in test-tube studies. Put them together and the worry is a slightly higher chance of bruising or bleeding, like nosebleeds, bleeding gums, or cuts that take longer to stop.

I want to be honest about the strength of this, though. The celery effect has only been seen in the lab, never proven in real people, so it's a theoretical concern, not a red alert. Eating celery as a normal vegetable is very unlikely to matter. Concentrated celery seed extracts are where I'd pay more attention. If you take both regularly, or you're on other blood thinners, just give your pharmacist or doctor a heads-up.

From our pharmacist’s overview on the Fish Oil Triglycerides page

“Nearly everything on this page points at one danger for anyone receiving Fish Oil Triglycerides (Omegaven): bleeding. Omega-3 fats can slow clotting somewhat on their own, and 202 of the interacting supplements and herbs add their own blood-thinning or antiplatelet effects on top of that, so combining them casually is a real mistake.”

About Celery

What is Celery?

Celery
  • High blood pressure
  • Fluid retention (diuretic)
  • Joint pain and inflammation
  • Anxiety and sleep
  • Digestive support

Celery is a common vegetable that is also taken as a seed extract or oil supplement, mainly for blood pressure, fluid retention, and joint discomfort. Human evidence for these supplement uses is limited and mostly preliminary, so it should not replace proven treatments. Celery is generally safe as food, but concentrated supplements and possible allergic reactions warrant caution.
