9 Surprising Things That Can Happen When You Take Vitamins

2. Increased Bleeding Risk

It’s crucial to let your doctor know when you’re taking any sorts of multivitamins or other supplements. “Because patients may erroneously think that just because vitamins and supplements are sold over the counter are safe, they may not report to their doctor that they take these supplements,” says Dr. Michos. However, patients may run into issues when supplements have adverse interactions with prescription medication. “For example, many people don’t realize that both fish oil and Ginkgo biloba can potentially cause increased risk of bleeding, especially when combined with other blood thinning medications,” as Dr. Michos explains. Definitely report any and all supplements to your physician to avoid the risk of these drug interactions.
