Glossary vitamin A

fat-soluble nutrient crucial for vision, immunity, and skin health

It exists in two primary forms: retinoids (found in animal products) and carotenoids (found in plant-based foods). Deficiency in vitamin A can lead to vision problems, including night blindness, and can compromise the immune system.
