How to tell if you’re getting too much Vitamin A

When we have too much of a certain vitamin in our bodies, it is called hypervitaminosis or vitamin toxicity. It is possible to overdo consumption of Vitamin A in both, short and long periods of time. This happens either by consuming large amounts of Vitamin A in a small amount of time or by gradually overdoing Vitamin A intake over an extended period of time leading to the accumulation of a large amount of the substance in our bodies.

Generally speaking, conditions that happen in short time-frame are called ‘Acute’ and those that build up over longer periods of time are called ‘Chronic’.


If you’ve been overdoing your Vitamin A, here are some of the possible symptoms. If the condition has happened over a short span of time (acute), its symptoms are different than if it developed over a longer period of time (chronic).

  • Abdominal pain
  • Drowsiness
