I will test at 3 months to see what happens (just because I want to know how long it lasts). But after that (all depending on the result), maybe it would be best to take small amounts of D3, now that I'm at a healthy level...just to 'maintain' that level. What do you think? If someone is just wanting to 'maintain' their current level, what is the recommended dosage of D3? Or is that necessary? Or should the body 'maintain' on it's own?
