Could Taking Vitamin E Supplement Post-Op Mommy Makeover Affect the Results?

Before surgery, high doses of vitamin E are known to cause a higher risk for bruising and bleeding.

After breast augmentation surgery, some surgeons use Vitamin E to help reduce the chance of developing a hard breast with capsular contracture.  But the scientific data on this is pretty sparse.  I wouldn't be very upset if you decided to skip it.  

I advise my patients to avoid "extra" Vitamin E 2 weeks before and after surgery as it is a fat-soluble vitamin that could competetitively inhibit absorption of Vitamin K (another fat-soluble vitamin), which is necessary for proper blood clotting. (Vitamin A and Vitamin D in excessive doses can do the same, as can overdoing it with Omega-3 oils, fish oils, etc.)

In general, one should consider taking a multivitamin prior to and after surgery, but avoiding excessive doses of "additional" vitamin supplements if your dietary intake is otherwise "normal and healthy." Exceptions to this are patients with specific vitamin deficiencies, malabsorption syndromes, or gastric bypass patients.

Your surgeon likely has a good reason for his/her advice; I would recommend following it, and if curious, ask the reasoning behind it. But 1000 IU per day is not excessive and taking it or not taking it will have essentially the same effect if all else is well. Best wishes!
