Vitamin A (Retinol)
Vitamin A, or Retinol, is essential for vision, immune function, and skin health. It is critical in cell growth and differentiation and is primarily found in carrots, sweet potatoes, spinach, and liver. Vitamin A helps maintain good vision in low-light conditions and supports the growth and repair of body tissues. Adults should aim for 700-900 micrograms per day, with higher amounts recommended for pregnant and breastfeeding women. Deficiency can lead to night blindness and immune deficiencies, while excess intake can cause symptoms like dizziness and nausea. Vitamin A was the first vitamin to be discovered.
