Vitamin A

Vitamin A is an essential nutrient that plays a crucial role in maintaining healthy vision, immune system, and skin. It is a fat-soluble vitamin that is found in animal-based foods such as liver, eggs, and dairy products, as well as in plant-based foods such as sweet potatoes, carrots, and spinach. Vitamin A deficiency can lead to a range of health problems, including night blindness, dry eyes, and increased susceptibility to infections.

However, it is important to note that excessive consumption of vitamin A can also be harmful and lead to toxicity. Therefore, it is recommended to consume vitamin A in moderate amounts and always consult with a healthcare professional before taking any supplements. Vitamin A supplements can be beneficial for those with a deficiency, but it is important to only take them under the guidance of a healthcare professional and not exceed the recommended dosage.
