Had a blood test to test for thyroid issues. Came back clear, but that I have vitamin D insufficiency.
Was advise to take 20-50mcg(800-2000iu) of vitamin D per day for twelve weeks. Then get retested. When levels reach normal then to reduce this to 10mcg(400iu) per day.
After advice on this forum, I bought doctor's best vitamin D 50ug, softgels. Can't quite work out how 20-50mcg etc is translated into 50ug? How many tablets would that be? The suggestion on the container is one tablet per day?
