Another possibility for the higher calcium, I have been talking to some tei practitioners lately and have been told that in slow oxidiser women taking large amounts of calcium will lower the calcium that shows in the hair then you end up sitting in 4 lows for years.
I was also told that most slow oxidser women have much higher calcium and magnesium levels than is showing on the hair test and that this is going to be especially true if your calcium was higher at any time earlier in the program.
So no longer taking calcium might have allowed your levels to raise back up.
