Question 5

Normal Levels

Accepted Answer

Vitamin D Deficiency: Less than 20 ng/mL or less than 50 nmol/L. Mild Vitamin D Deficiency: Between 20 to 29 ng/mL or 50 to 74 nmol/L. Normal Levels: From 30 to 50 ng/mL or 75 to 125 nmol/L. Vitamin D Excess: More than 50 ng/mL or more than 125 nmol/L, which may indicate vitamin D excess. Vitamin D deficiency can lead to health problems such as osteoporosis or muscle weakness.
