Dear Vitamin D Council, Thank you for your much needed work. My husband is 48 years old, Indian, and has adult onset asthma for 5 years. Luckily, the asthma only occasionally flares up but he has to manage his cough associated with it. We recently discovered his Vit D level is just 7 ng/ml. He has started 60,000 UI D3 cholecalciferol granules had with water weekly for 10 weeks. someone suggested he take 60,000 UI DAILY for 10 days. That seemed a bit drastic to us, on reflection. What do you think ? Ofcourse we mean to test again after 10 weeks and decide on further dosage. We have also decided he needs to take 30,000 UI monthly for the rest of his life once his vit d level is between 40-50 ng/ml. we will keep testing for vit d level once or twice a year too.
