A doctor has provided 1 answer

D3: Hi. Most of us feel your serum 25-hydroxyvitamin D level should be over 30; I try for mid-30's to 40's in my patients. Cholecalciferol, or vitamin D3, is what is most commonly used for nutritional replacement (ergocalciferol, or vitamin D2, is also used although less preferred than D3). You should take at least 5,000 units/day and have your 25-hydroxyvitamin D level checked again in 2-3 months.
