@osteopatient2026 early on I was taking calcium a few hours before the injection, thinking the pth drug would then need to draw less from my bones. It never gave me nausea. But I never figured out if it kept any calcium in my bone. I haven't ferreted if a person can help determine whether the hormone pulls calcium from the kidneys, the bones or the intestine.
What makes sense to you? Do you suppose that no matter the amount of calcium in the bloodstream a certain amount of injected pth1-34 is going to draw the same amount of hormone, as your wise caution suggests.
I abandoned calcium two hours, and now take magnesium two hours before to help determine that drawn calcium goes back into my bones in measured amounts.
