Great question! When it comes to surgery, some supplements can affect bleeding, anesthesia, or healing. Here’s a general guideline: • Biotin: Usually considered safe to continue before surgery, as it doesn’t typically affect bleeding or anesthesia. • Zinc, Vitamin C, Folic Acid, Vitamin B3, B12, Multivitamins: Generally safe and often encouraged to support healing. • Vitamin A and Vitamin E: These can sometimes increase bleeding risk, so doctors often advise stopping them at least 1-2 weeks before surgery. • Fish oil: Also can increase bleeding risk, so it’s usually recommended to stop 1-2 weeks prior. • Potassium: Typically safe but depends on your kidney function and other health factors. You should always check with your surgeon or healthcare provider. They’ll give you personalized advice based on the type of surgery and your health.
