Im not sure why but they elevated up to 26 .. from 18 within the past month.. Im not doing anything different.. except... I did purchase the Turky Hill light ice cream.. its usually on sale at Wegmans for 2.99.. That is the only thing I have done.. but.. on the pkg it does say.. it has calcium and Vitamin D.. I looked on the ingredients and it says Vitamin D3.. Im wondering ..if there really is enouhg in there to raise it or if its coincidence... anyone have any idea? I do try to remember to take my Calcium and Vitamin D but.. sometimes I forget. but I've been taking it.. for the past 3 months.. is just strange that it was raised.. and after eating that ice cream..
