I'm hoping you folks can offer some insight. A couple years ago, I was tested and had low vitamin D. And I had some pretty bad symptoms from it (fatigue, extreme sunburning from miniscule exposure). After a year and 9 months of supplements (oral and light), I overshot the mark and had the alarmingly high level of 136. That was this past summer. I stopped the supplements... then I forgot and started them again for a few weeks in october... then stopped again. None since mid-october. No calcium since then, either, as it was also high Since Nov 1st I have been in the subtropics, camping, and outdoors wearing shorts every day from 9 or 10 am till after dark. It is almost always sunny where I am. But I started to have mild deficiency symptoms again -- sunburn, and craving the sun. So I went in for a test, and my level is now 60. Calcium is normal. I do take vitamin K2. I only bathe every 2-4 days, so I am not removing vit D from my skin before it gets absorbed. I am wondering how on earth I used up my massive oversupply of vitamin D so quickly, and why I am not making enough on a daily basis to have a higher blood level than I do. Any ideas?
