Thank you for your question regarding what vitamins should you stop taking before surgery. You should stop taking Vitamin E, Vitamin C, Vitamin K, and Vitamin B complex vitamins before your surgery. Also, you should stop taking your daily multivitamins. The problem with Vitamin C is that Vitamin C is such a strong detoxifying vitamin, that it can overpower some of the administered anesthetics. Vitamin C can make the anesthesia more difficult since it is a powerful detoxifier. It is thought that Vitamin E can cause bleeding. So it is best to avoid Vitamin E before surgery. Vitamin K can also cause bleeding. Again it is best to avoid Vitamin K before surgery, Vitamin B should also be avoided because Vitamin B complex can interfere with other medications. Specifically, vitamin B6 can interfere with the efficacy of certain antibiotics and thus can increase your chances of infection after surgery. Other herbs and supplements to avoid according to the Aesthetic Surgery Journal include: Vitamin E Fish oil and omega 3 Garlic Red chili pepper (capsaicin) Ginkgo biloba Saw palmetto Ginseng Chondroitin and glucosamine Bromelain Arnica montana Licorice Ginger Oil of wintergreen Arnica montana Feverfew Devil’s claw Seasonal tonic tea Japanese honeysuckle Baical skullcap root Fritillaria bulbs Ta gastronol tea Poncitrin (jishi) Dan Shen Chinese agrimony Chinese peony Geum japonicum Guilinggao (tortoise jelly) Kangen-karyu Bak Foong pill Thank you for your very good question regarding what vitamins you should stop taking before surgery.
