Re: Vitamin D supports cognitive ability in seniors

No. A recent study by researchers at Duke University found that elderly men and women who consumed higher levels of calcium and, in particular, vitamin D are significantly more likely to have greater volumes of brain lesions, indicating regions of damage that can increase risk of cognitive impairment, dementia, depression and death. The team found that vitamin D intake, (mean 341 IU and maximum intake 1014 IU),

The amount of vitamin D are given, but unfortunately forgot calcium tell (or maybe it's especially so ???). As we know too much calcium is harmful. G. Abraham calls max 400-500mg per day of Ca and Mg 700-1,200.

Excess calcium may also predispose to luteal deficiency in premenopausal women, 1 mM calcium chloride having been found to decrease luteal hormone (LH) binding to the plasma membrane of the corpus luteum and causing luteolysis [88]. It also increases synthesis of prostaglandin F2x, which is luteolytic [88, 89]. There is no evidence that calcium supplementation in excess of 500 mg prevents or reverses PPMO [7, 8, 25]. For the above reasons, 500 mg of calcium in the form of citrate is recommended.
