Vitamin A: Benefits, Uses, Dosage & Complete Guide
Vitamin A is an essential fat-soluble vitamin that plays a vital role in maintaining healthy vision, supporting the immune system, promoting healthy skin, and supporting normal growth and development. It is one of the most important nutrients for overall health and is naturally found in both animal and plant-based foods.
Vitamin A is available in two primary forms: preformed Vitamin A (retinol), found in animal foods, and provitamin A carotenoids, such as beta-carotene, found in colorful fruits and vegetables. Because the body cannot produce enough Vitamin A on its own, it must be obtained through diet or dietary supplements.
As awareness of nutritional wellness continues to grow, Vitamin A supplements are widely used in Pakistan to help support eye health, immunity, skin health, and overall well-being.
What Is Vitamin A?
Vitamin A is a group of fat-soluble compounds that includes retinol, retinal, retinoic acid, and provitamin A carotenoids. These compounds are essential for maintaining normal vision, healthy skin, immune function, and cell growth.
The body converts beta-carotene from plant foods into active Vitamin A as needed, making it an important dietary source.
