All About Vitamin A

In this episode of Whole Body Health, Dr. JP Saleeby discusses the importance of vitamin A, its sources, different forms, health benefits, potential risks, and how to incorporate it effectively into your daily routine.

Vitamin A is critical for eye health and retinal function, for supporting the immune system, and for maintenance of skin and mucous membranes as well as for embryo development. Vitamin A helps prevent night blindness and cataracts, skin issues, a weakened immune system, premature aging, and lung disease, and can reduce effects of HIV/AIDS and measles.

Forms and Sources of Vitamin A:

Vitamin A exists in two primary forms:

  1. Retinol – Found in animal-based foods such as oily fish, liver, eggs, cod liver oil, butter, and cheese.

  2. Carotenoids – Derived from plant-based foods like carrots, squash, papaya, tomatoes, red bell peppers, sweet potatoes, and dark leafy greens. Bright orange fruits and vegetables are typically rich in carotenoids.
