Vitamin A is also necessary to maintain a healthy heart, lungs, kidneys, and other organs. There are two types of vitamin A. Preformed vitamin A is found in meat, poultry, fish and dairy products whereas, Provitamin A is found in fruits, vegetables and other plant-based products. Beta-carotene, which is found in many foods and supplements, is the most common form of provitamin A.

In addition to offering you various health benefits, excessive consumption of vitamin A can also be hazardous for you. Let us examine a few of those side effects that can result in health problems:
- The side effects of a vitamin A overdose include nausea, vomiting, vertigo, bone pain, sensitivity to bright light like sunlight and blurred vision. Vitamin supplements and drug overdoses are the main causes of this.
