Curious if you know how long it takes for a high VIt D level to drop when NOT exposed to sun. My practitioner tested my level in mid September, and although I had not been taking an excessive amount of Vit D (1-2000 at most through the summer if I didn't get sun and had just bumped up to 4000 since I in the sun much less) my levels came back at 96. I had spent some time in the sun–enough to get a nice tan this year. But was shocked to see a 96. My practitioner advised cutting my intake in half and have done that, but wondering if there are any parameters on how fast a level like that can drop when sun exposure stops? I want to make sure my level doesn't fall too far with cold and flu season coming around. Any thoughts? I'm currently taking just 2000 a day for at least a month or so now. Hate to spend for another test so soon but really curious about it coming down into a little more reasonable range. Have had no colds, flus, nothing and enjoying fairly good health. I weigh around 133-135. Thanks.
