The word “vitamin A” is a catch-all for a variety of fat-soluble compounds, called retinoids that include beta carotene, retinyl palmitate, and retinol. It is necessary for the healthy formation and operation of numerous body components, including vision, the skin, and the body’s immune system.

Vitamin A performs several vital tasks in the body, including:

• Helps the body’s natural defense mechanism fight illness and infection.
• It plays a crucial part in vision and eye health. Rhodopsin, a molecule required for low light vision and color vision, is created when the retinal, the active component of vitamin A, interacts with the protein opsin.
• It also assists in maintaining and protecting the conjunctiva, which is a thin membrane that covers the inside of the eyelids and the cornea, the eye’s outermost layer.
• Assists in forming and maintaining strong bones and teeth.
• Assists in maintaining surface organs like the inner ear, bladder, lungs, skin, and intestines.

Vitamin A has a variety of purposes, including:

• Vitamin A deficiency – Used primarily to tackle vitamin A deficiency.
• Immunity – Keeps a person’s immune system strong and operating well.
• During pregnancy – Enables healthy development of the baby. It can also help avoid night blindness and xerophthalmia (dry eyes) in pregnant women.
• Vision problems – Consuming enough vitamin A helps avoid night blindness from developing and may slow the deterioration of your vision with aging.
• Acne and anti-aging – Vitamin A (retinol) cream application enhances skin tone, elasticity, and wrinkles in those with aging skin and is also beneficial for acne.
• White patches in the mouth – called oral leukoplakia, typically brought on by smoking and can be treated with vitamin A.

When a person consumes more vitamin A than what is healthy or has a lack of it, side effects may result, as follows:

• Diarrhea.
• Vomiting.
• Hazy Vision.
• Headache.
• Irritated skin.
• Joint ache.
