Vitamin A plays a significant role in our growth of bones. This vitamin protects our body from infections.  Like fungal or virus or bacterial infections. And it is very important for our normal vision, development, also it is necessary for reproduction, bone maintenance and for immune functions.  The lack of vitamin A caused for blindness or some disorders of our vision, like night blindness, dry eyes, and nutritional blindness. The deficiency of vitamin A also affects the reproductive functions. We can prevent these situations by the regular eating of fresh carrots and vegetables. And at the same time the excess quantity of vitamin A caused for headaches, nausea, dry and cracked skin. It also caused for liver diseases.  It is recommended to eat 700mcg of vitamin A for women and 900 micrograms for men per day. And always careful that there is a limitation of the value of vitamin a in our body, never exceed 3000mcg of vitamin A in each day.  And at the time of pregnancy eating more than1000 IU of vitamin A is not advisable.
