Vitamin A Safety

It is important to discuss vitamin A safety issues with your healthcare provider before taking the supplement, as high doses can cause serious problems. Since most people get enough vitamin A through their diet, supplementation is not necessary for the average person. To help ensure safe use of vitamin A, talk to your healthcare provider if you have liver disease or a zinc deficiency.

Is Vitamin A Safe?

Normal intakes of vitamin A are probably safe for most people. However, high doses can cause problems, and even low or normal doses may not be safe for people with certain medical conditions. You should talk with your healthcare provider prior to taking vitamin A if you have:
 
  • Alcoholism
  • A fat malabsorption disorder, such as:
 
 
  • Liver disease, such as cirrhosis, liver failure, or hepatitis
  • Malnutrition
  • Zinc deficiency
  • Any allergies, including allergies to foods, dyes, or preservatives.
     
Also, let your healthcare provider know if you are:
 
  • Pregnant or thinking of becoming pregnant
  • Breastfeeding.
     
You should also be sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
