Low Vitamin D Hard on Aging Brain For Males

Brain Size versus vitamin D levels is a linear relationship pointing out that only high vitamin D levels give full brain size. This confirms prior studies suggesting high doses are needed for health.

low vitamin D levels increase the risk of developing mild
cognitive impairment (Ouma et al., 2018) and Alzheimer’s dementia
(Littlejohns et al., 2014; Bivona et al., 2021; Navale et al., 2022). In
contrast, Karakis et al. (2016) reported that vitamin D status was related
to various subclinical parameters of advanced brain aging, but not risk
for dementia in participants from the Framingham heart study (Karakis
et al., 2016).

In a study on very
old participants aged 85 and older, very low, but also very high levels of
vitamin D were associated with cognitive impairment (Granic et al.,

The quartiles are defined as
Q1 <16.8 ng/ml = <42 nmol/l

Q2=16.8 – 22.6 ng/ml = 42 – 56.5 mmol/l

Q3=22.6–28.9 ng/ml = 56.5 – 72.25 mmol/l

Q4>28.9 ng/ml >72.25 mmol/l
