I am curious about when to stop taking nutritional supplements and herbal supplements before and after surgery.

Since health supplements can affect bleeding and recovery depending on the ingredients before and after surgery, it would be safer to consult with your doctor at least 1 to 2 weeks in advance to confirm whether to stop taking them, and to make sure to share the product name, ingredients, and dosage with the hospital.

Generally, supplements that can affect bleeding, such as Omega-3, Vitamin E, and red ginseng, are often discontinued 1-2 weeks before surgery. They are typically resumed after confirming hemostasis and wound healing, with the approval of your primary physician. Probiotics also require careful consideration, especially if you have a compromised immune system or have undergone intestinal surgery.

It's most accurate to show the clinic the product name, daily dosage, EPA/DHA and Vitamin E content, and a photo of the ingredient list including red ginseng/ginkgo biloba.

For the most part, it's safer to manage your nutrition during the discontinuation period with protein-rich meals, fruits, vegetables, and adequate hydration rather than supplements.
