What is Vitamin A Requirement?

Vitamin A is essential for a healthy immune and reproductive system, healthy vision, maintenance of strong bones and teeth, red blood cell production, tissue repair and skin health. It is a fat soluble vitamin that also acts as a powerful antioxidant in the body. Vitamin A is essential for many physiological processes, including maintaining the integrity and function of all surface tissues (epithelia). It can also help with skin problems such as some types of acne and hyperkeratosis. Vitamin A plays a critical role for vision under conditions of poor lighting, bone growth, reproduction, cell functions and for maintaining a healthy immune system.

RDA for retinol is 900 micrograms (3,000IU) and 700 micrograms (2,333IU) for males and females respectively. Your need for retinol increases in pregnancy, childbirth, infancy, and childhood growth.

How It Affects Your Body

Vitamin A deficiency (VAD) mostly occurs in children on unbalanced diets. VAD can affect growth in children and lead to serious complications such as weak immune function. VAD also increases the severity of diarrhoea and has been associated with increased risk of infectious morbidity and mortality risk of infections. The most specific clinical effect of inadequate vitamin A intake is xerophthalmia or dry eye, which can result in night blindness, conjunctival xerosis, Bitot's spots, corneal xerosis, corneal ulceration, and scarring. People with VAD tend to have a low iron status which can lead to anaemia. Moreover, VAD is associated with chronic malabsorption of fats and impaired bile production and release. Furthermore, pregnant women with low vitamin A will have difficulties to support maternal and fetal tissue growth. Besides, breastfeeding women with low vitamin A will have difficulties to support lactating.

Symptoms

Diet

A low-fat diet can affect the absorption of carotenoids.

Suggested Lifestyle Changes

Dietary Recommendations:

  1. If you are vegetarian or vegan, ensure that you are getting sufficient retinol (active form of vitamin A) from vitamin A fortified foods. Retinol is typically found in animal food sources, such as chicken or beef liver, butter, cod liver oil, tuna and eggs.
  2. Carotenoids, precursors to vitamin A, come from leafy green vegetables (e.g. spinach, kale), orange and yellow vegetables (e.g. carrots, pumpkins, tomatoes, red capsicum), as well as fruits like papaya and mango.
  3. As vitamin A is fat-soluble, taking it with food that contains fat (e.g. yoghurt, eggs, oil) will optimise absorption.

Supplement Recommendations:

  1. According to RNI Malaysia, the recommended intake of vitamin A is 600mcgorday. It is advisable to consume vitamin A not exceeding 3,000mcgorday. For pregnant and lactating women are suggested to consume 2,800mcgorday.
  2. Please take note that the daily recommended intake for vitamin A is inclusive of both dietary and supplementary intake.
