Vitamin A is an important nutrient that plays a key role in supporting vision, strengthening the immune system and ensuring the normal functioning of major organs. Its importance also extends to facilitating reproduction, promoting growth and supporting overall development. In the context of food sources, it is imperative to focus on foods high in vitamin A to meet these important health requirements.
1. Introduction to Vitamin A
Vitamin A stands as a key player in the realm of vitamins and essential micronutrients. As an indispensable component, it significantly contributes to overall health and is available in natural food sources and dietary supplements.
1.1 Benefits of Vitamin A
Vitamin A is crucial for our bodily functions, offering a range of benefits:

Consequences of Vitamin A deficiency:
- A major cause of blindness in less developed countries, though rare in developed nations due to adequate dietary intake.
- Increases susceptibility and mortality from infections like measles and diarrhea.
- Linked to higher anemia rates and mortality in pregnant women, while also adversely affecting fetal growth.
- Can lead to skin problems, including hyperkeratosis and acne.
- Some groups, like premature infants, individuals with cystic fibrosis, and pregnant or breastfeeding people in underprivileged areas, face higher risks of Vitamin A deficiency.

5. Daily Requirement of Vitamin A
Vitamin A is an important health nutrient that is often measured in International Units (IU) on the Nutrition Facts label. However, the Institute of Medicine now recommends using micrograms (mcg) of Retinol Activity Equivalents (RAE). This change is due to varying absorption rates between preformed vitamin A and provitamin A carotenoids. Following the Food and Drug Administration’s (FDA) updated labeling regulations, starting from July 2018, large companies will switch from IU to mcg RAE when listing Vitamin A content.
- Recommended Dietary Allowance (RDA): For adults aged 19 and older, the RDA is set at 900 mcg RAE for men (which is about 3,000 IU) and 700 mcg RAE for women (approximately 2,333 IU).
- Tolerable Upper Intake Level (UL): This is the highest amount of daily vitamin A intake that is unlikely to cause adverse health effects. The UL for vitamin A from retinol sources is pegged at 3,000 mcg of preformed vitamin A.
It’s essential to understand these measurements for proper vitamin A intake. Exceeding the UL can lead to health issues, particularly from preformed vitamin A (found in animal sources and supplements), as it is more readily absorbed and stored than beta-carotene from plant sources.
