Patient's question:
On September 27th, I had my baby's blood calcium tested and checked for vitamin D. The community doctor said the baby is calcium-deficient and recommended taking D3, which is cholecalciferol milk. After drinking one bottle, the baby doesn't need to take D3 for a month, just to supplement calcium for a month. Then, on October 27th, the baby drank another bottle of cholecalciferol milk. By November 27th, we will retest the blood calcium to see the results. My friend's baby had the test done, and I noticed the results were even slightly lower than my baby's. I went to another hospital to see a pediatrician, and the doctor said there is no calcium deficiency but a deficiency of vitamin D2. I'm a bit confused. Will the cholecalciferol milk I gave my baby supplement too much and harm its physical and mental development?Doctor's answer:
Normal values. Blood 25-hydroxyvitamin D > 30 ng/ml indicates sufficient vitamin D levels, with an ideal range of 30-50 ng/ml. Vitamin D2 and vitamin D3 have the same effect in the body. Vitamin D2 generally comes from plant-based foods, while vitamin D3 is derived from animal-based foods and skin synthesis. Focus on the total amount (25-OH-D) rather than worrying about which one is low, as it's not related to the nature of your regular diet. If your diet is rich in calcium (usually found in dairy products), there's no need for long-term additional calcium supplementation. A daily intake of 400 IU of vitamin D is sufficient for prevention.
