How much vitamin d should i take.? i am not often in the sun, and someone recommended a 5000 dose sublingual once a day, so i take them. any harm?

Depends: Hi. There's no absolute right level of 25-hydroxyvitamin D (25-D) in the blood. My personal goal for patients is to be at or above the mid-30's. It's estimated that you raise 25-D by about 6 for every 1,000 units of oral vitamin D you take. Therefore, based on how low you are, that helps you estimate a reasonable amount to take. Vit D toxicity is a myth; only calcitriol can be toxic. Good luck!
