Q. My pain clinic doctor put me on 50,000 units vitamin D twice a day. That’s 100,000 units a day, and it seems like a lot. The pharmacy called to verify the prescription. Is this dose safe?

A. That is an extremely high dose of vitamin D. It may put you at risk of toxicity. Please check back with your doctor or get a second opinion.

    My vit d is low so I am now on 40,000 of colecalciferol vit d3 a day for 10 days and then reduced to 800 for 30 days I then go back for a blood test. I am half way through the high dose I’m a little worried because on the comments I have read I’ve not found anyone else on this dose. I hope it’s safe.

    Hi! I am 47 and have bipolar disorder. I tend to isolate myself in the house and live in Michigan. I recently found out my Vit D level is 14. I am also obese. Diabetes, and heart disease runs in my family. I was prescribed Vet D 52,000 IU daily for 1 week and then every other day. I am tired all the time. I am not worried about overdosing I am more worried about getting my levels up. I have toned of those lamps that gives you Gives off vitamin D. How long should I sit under it?

    That sounds like it is related to his COPD. I would recommend he calls his physician as soon as possible.
