What Is Vitamin A? Understanding the Basics

Vitamin A is a fat-soluble vitamin that plays a fundamental role in human health, yet its importance is often underestimated. As research continues to reveal new vitamin a benefits, understanding its function has never been more crucial, especially in 2025. This nutrient is essential for growth, immunity, vision, and the maintenance of healthy skin and tissues.

Vitamin A comes in two primary forms. Preformed Vitamin A, or retinol, is found in animal-based foods such as beef liver, eggs, dairy products, and salmon. Provitamin A carotenoids, like beta-carotene, are present in plant-based foods including carrots, sweet potatoes, spinach, kale, and cantaloupe. The body efficiently converts these carotenoids into active Vitamin A, though the rate can vary depending on individual factors like genetics and overall diet. This conversion process is central to unlocking the full spectrum of vitamin a benefits, especially for those who follow plant-based diets.

To meet daily vitamin a benefits, the Recommended Dietary Allowance (RDA) is 900 micrograms (mcg) for men and 700 mcg for women, with higher needs during pregnancy and breastfeeding. Bioavailability differs between sources, as whole foods generally offer better absorption than supplements. The table below summarizes top sources:

Animal Sources	Plant Sources
Beef liver	Carrots
Eggs	Sweet potatoes
Dairy (milk, cheese)	Spinach, kale
Salmon	Cantaloupe

Despite easy access in some regions, Vitamin A deficiency remains a global concern, affecting over 190 million children worldwide, particularly in developing countries and among vulnerable groups.
