Too much of a good thing can hurt you – even for vitamins. Some people take vitamins because their diet is not balanced and does not provide all the nutrients their body needs. Others take vitamins to boost their immune system to prevent illness. Whatever your reason, it is important to know your limits.

The Food and Drug Administration (FDA) is responsible for providing you a limit for what is safe for you to stay healthy and avoid an overdose, which is called the Recommended Daily Allowance or RDA. According to the warfarin package insert, Vitamins C and E, found in many multivitamins can influence your INR test results.1

Each vitamin and mineral helps your body’s cells, blood and organs work properly when taken as directed. To learn your safe limits, talk to your doctor or nurse before starting any new vitamin or dietary supplement.
