About vit D deficiency treatment;

Detailed Answer:
Hello and thank you for asking!
I can understand your concern regarding to your husband's health.
In Vitamin D deficiency (when the vit D level is under 15) 50 000 UI weekly is the most common recommended dose.
The Vit D intoxication is very rare and happens especially while taking Vit D3 ( the active form of Vit D) and in these cases a close monitoring of calcium level (once in a week) is recommended.
If the renal function is no impaired there is no reason why to take Vit D3, as the kidneys are responsible to convert VitD2 in the active form ( Vit D3).
So, i would recommend 50 000 UI once in a week with calcium supplements ( if the calcium level is low) and try to get exposed to the sun.
Wish him good health!

Best wishes,
Dr.Mirjeta
