A deficiency in Vitamin A would result in getting infectious diseases and vision problems. The Recommended Dietary Allowance (RDA) of Vitamin A required for an Asian Adult is 750mcg, while a lactating Asian woman’s RDA is 1200mcg.
Meanwhile, If you get too much vitamin A, you can become sick. Over-consumption of Vitamin A can lead to jaundice, nausea, loss of appetite, irritability, vomiting, and even hair loss. Vitamin A is a fat soluble vitamin, and therefore, needs to be consumed with fat in order to have optimal absorption.
Acute Vitamin A poisoning usually occurs when an adult takes several hundred thousand IUs of Vitamin A. Symptoms of chronic Vitamin A poisoning may occur in adults who regularly take more than 25,000 IU a day. Babies and children are more sensitive to vitamin A, and can become sick after taking smaller doses of Vitamin A or Vitamin A-containing products such as retinol (found in skin creams).
Large amounts of beta-carotene will not make you sick. However, increased amounts of beta-carotene can turn the skin yellow or orange. The skin color will return to normal once you reduce your intake of beta-carotene.
