Did you know that vitamin A is one of the most important nutrients for your health and well-being? It can help you see better, protect your skin, boost your immunity, and support your reproductive and fetal health. But what exactly is vitamin A and how does it work in your body?
In this comprehensive guide, you will discover the different forms and sources of vitamin A, and how it affects your health in profound ways. You will also learn how to achieve the right balance of vitamin A intake to avoid deficiencies and toxicity.
Vitamin A: The Two Forms and Their Functions
Vitamin A is a fat-soluble nutrient that comes in two main forms. The first one, preformed vitamin A (retinoids), is found in animal products and can be used by the body directly. The second one, provitamin A (carotenoids), is found in plant-based foods and needs to be converted by the body. This nutrient is involved in various bodily functions, such as vision, immune system function, skin health, and reproductive health.
Vitamin A: The Key to Healthy Eyesight
Vitamin A is vital for keeping our vision healthy. It is a part of rhodopsin, a protein in the eyes that helps turn light into electrical signals that go to the brain. This process is important for seeing in dim light. Lack of vitamin A can cause night blindness, a condition where the eyes have trouble adjusting to darkness, affecting overall vision.
