t have a malfunctioning parathyroid - because excess
calcium from pills etc. can give you a heart attack or stroke along
with organ damage and kidney stones. Be very careful. Checking calcium is easy and fairly cheap.
And if you have a parathyroid problem, do NOT take vitamin D. If you have low vitamin D in your blood and high calcium, do not try to enter more vitamin D into your diet. If you do, you put yourself at substantial risk for a stroke.
