Vitamin A: More Than Just Eye Health

Vitamin A is an essential fat-soluble nutrient vital for numerous bodily functions beyond its well-known role in maintaining healthy vision. It actively supports immune system strength, reproductive health, and guides cell growth and development throughout the body.

This essential vitamin exists in two primary forms: preformed vitamin A (retinol) found in animal products like liver, eggs, and fatty fish, and provitamin A carotenoids, such as beta-carotene, abundant in colorful plant-based foods like carrots, spinach, and sweet potatoes. For optimal absorption, carotenoids are best consumed with dietary fats.

While vitamin A deficiency is uncommon in the United States, it can occur in individuals with malabsorption disorders or restrictive diets. Both deficiency and excessive intake, particularly from supplements or frequent liver consumption, can pose health risks, underscoring the importance of balanced dietary intake.
