Vitamin A is very important for us because it helps us have good vision, a healthy working immune system, strong bones, reproduction and cell division. Recommended Dietary Allowance (RDA) for adult women for vitamin A is 2330IU. For adult men, it is 3000IU. Where it is good for the bones in moderate amounts, in very large amounts, it may actually weaken bones. Above 10000IU intake of vitamin A is considered to be very toxic.

Some good sources of vitamin A are liver, fortified milk and cheese, orange/yellow vegetables and vegetables like carrots, cantaloupes, and apricot.
