Talking to your surgeon about supplements.

Most surgeons restrict certain supplements in the days before surgery. Some interact with anesthesia. Some affect platelet function and bleeding. Some are simply unstudied at the doses people take them at. The right move is to disclose everything early and let your surgeon make the call. This article is about how to have that conversation well.

Why disclosure matters

Surgeons cannot manage what they do not know about. The list of supplements that have been flagged in the surgical literature is long and includes some that consumers consider routine. Anesthesia interactions, bleeding risk, and effects on liver and kidney clearance are all real. The risk is not that any single supplement is dangerous on its own. The risk is that an undisclosed combination produces a response your team did not plan for.

What is typically restricted

Common categories that show up on pre-op stop lists include high-dose fish oil and other anticoagulant-adjacent supplements, certain herbal blends with documented anesthesia interactions, very high-dose vitamin E, and various weight-loss or "energy" supplements with stimulant content. The exact list and the exact stop window vary by surgeon and procedure. The right list is the one your surgical team gives you, in writing, with dates.

How to bring it up at the pre-op visit

A simple opening works. "I want to make sure you have a complete list of everything I am taking, including over-the-counter and supplements. Can we go through it together so you can tell me which to pause and when." Bring the list printed, with doses and timing. Ask for the stop dates in writing. Ask how you should resume after surgery, since this is a question many people forget to ask and many surgeons do not volunteer.

A few questions worth asking

Which of these should I stop and when. When can I resume. Are there any I should keep taking through surgery. Are there interactions with the anesthesia plan you are using. Is there anything you would specifically recommend during recovery. The questions are short. The answers compound.
