Vitamin A, a fat-soluble vitamin, is essential for maintaining a healthy body. It comes in two forms: preformed vitamin A (retinol) found in animal sources, and provitamin A carotenoids found in plants.
Retinol is crucial for vision, particularly in low-light conditions. It aids in the production of rhodopsin, a pigment in the retina. Vitamin A also supports cell growth and differentiation, playing a key role in developing and maintaining tissues like skin, bones, and mucous membranes. Additionally, it contributes to immune function, helping the body fight off infections.
Adequate vitamin A intake is vital for overall health. Deficiencies can lead to night blindness, dry eyes, skin problems, and increased infection susceptibility. Pregnant women need sufficient vitamin A for fetal development, but excessive intake can be harmful. A balanced diet rich in colourful fruits and vegetables, along with moderate consumption of animal sources, can typically provide enough vitamin A. Fortified foods and supplements are available. Still, it's essential to consult a healthcare professional before taking them, especially during pregnancy.
