Vitamin A is a crucial nutrient that plays a key role in maintaining healthy vision, supporting the immune system, and promoting cell growth. It is a fat-soluble vitamin that is essential for various bodily functions.
Vitamin A can be obtained from both animal and plant sources. Animal sources include liver, fish, and dairy products. Plant sources include carrots, sweet potatoes, and spinach.
Vitamin A is known for its role in promoting good vision, especially in low light conditions. It also helps in maintaining healthy skin, supporting the immune system, and promoting cell growth and development.
Deficiency of vitamin A can lead to night blindness, dry skin, and increased susceptibility to infections. On the other hand, excessive intake of vitamin A can lead to toxicity symptoms such as nausea, dizziness, and even liver damage.
The recommended daily intake of vitamin A varies by age and gender. For adults, the recommended daily intake is around 700-900 micrograms per day for men and 600-700 micrograms per day for women.
