1. Vision Health: 

Vitamin A is renowned for its role in maintaining optimal vision health. Retinol, an active form of vitamin A, is essential for the proper functioning of the retina, the part of the eye responsible for vision. Scientific studies have shown that vitamin A deficiency can lead to night blindness and other vision impairments (1). Additionally, vitamin A also helps protect against age-related macular degeneration (AMD), a leading cause of vision loss in older adults (2).


2. Immune System Support:

A robust immune system is crucial for fighting off infections and diseases. Vitamin A plays a vital role in supporting immune function by enhancing the integrity of the skin and mucous membranes, the body's first line of defense against pathogens. It also contributes to the production and differentiation of immune cells, such as lymphocytes and phagocytes, which play a vital role in immune response (3).

3. Healthy Skin:

Vitamin A is widely recognized for its positive effects on skin health. It promotes the growth and development of skin cells, helps regulate oil production, and supports the skin's natural barrier function. Research has shown that vitamin A derivatives, such as retinoids, are effective in the treatment of various skin conditions, including acne, psoriasis, and aging-related changes (4).

4. Growth and Development:

Vitamin A is essential for proper growth and development, particularly in children. It aids in bone growth, supports the development of teeth, and contributes to the normal development of various organs, including the heart, lungs, and kidneys. Several studies have highlighted the importance of adequate vitamin A intake during pregnancy for fetal development and reducing the risk of birth defects (5).

5. Antioxidant Properties:

Vitamin A acts as a potent antioxidant, helping to neutralize harmful free radicals in the body. Free radicals can damage cells and contribute to various chronic diseases, including cardiovascular disease, cancer, and neurodegenerative disorders. By scavenging these free radicals, vitamin A helps protect cells from oxidative stress and reduces the risk of chronic conditions (6).
