wolven7'Abnormal calcium metabolism has been implicated in human hypertension. Caffeine consumption may contribute to hypertension since it increases urinary calcium excretion.'
That makes sense. Fine.
It's toward the middle, where things get confusing:
'Caffeine abstinence (CAF-) increased fasting serum ultrafiltrable calcium in HTN and NTC, but not serum total calcium. Parathyroid hormone (PTH) levels decreased after CAF abstinence in 14 of 18 HTN subjects, including all seven subjects consuming less than 700 mg calcium daily.'
See? The beginning sounds bad, but that? That's weird.
Anyway, there you are. More weird things about caffeine and calcium interaction.
Ta.
