I know that PTH should be in the lower half of the reference range, but it seems - no matter what I do - I cannot get it down. Over the years, I measured PTH several times. Initially it was even above the reference range. After increasing may vitamin D, calcium and magnesium intake I could bring it down a little bit, but it was always clearly in the upper end of the reference range.
According to my latest blood test, my PTH is at 5.7 mol/L (reference range: 1.5 - 6.9), despite taking 4000 I.U. Vitamin D, 300 mg Magnesium (as Glycinate-Lysinate) and 600 mg Calcium (as carbonate) per day during at least half a year previously.
My vitamin D in the blood is currently at 53.2 ng/ml, which according to Chris Masterjohn is at the high end of a normal value.
Why is my PTH still that high? Do I eat still eat too much meat and phosphorus in relation to calcium? I would say on average, I eat about one egg, about 100-200 grams of meat and maybe 100 grams of cheese per day. I also take about 25 grams of collagen peptides per day.
What can I do to bring PTH further down? Should I further increase Vitamin D, even though the blood level is already quite high?
