How does retinol treat a vitamin A deficiency?

By taking a vitamin A supplement, you can treat a vitamin A deficiency. Vitamin A deficiency is rare in a developed country, but shows up where malnutrition is present, and can lead to dry eyes, skin disorders, diarrhea, infections, blindness, and respiratory disorders.

However, you should talk to your doctor about your vitamin A and retinol dosage since too much vitamin A can result in an overdose. Overdoses of retinol can cause vitamin A toxicity and symptoms like severe headache, bone and joint pain, fatigue, dizziness, changes in your menstrual period, dry skin around your mouth, hair loss, vision changes, loss of appetite, vomiting, jaundice, dark urine, stomach pain, pain behind the eyes, and nausea.
