Vitamin D deficiency tagged posts

Dementia is one of the major causes of disability and dependency among older people worldwide, affecting thinking and behaviors as you age. But what if you could stop this degenerative disease in its tracks?

A world-first study from the University of South Australia could make this a reality as new genetic research shows a direct link between dementia and a lack of vitamin D.

Investigating the association between vitamin D, neuroimaging features, and the risk of dementia and stroke, the study found:

• low levels of vitamin D were associated with lower brain volumes and an increased risk of dementia and stroke
• genetic analyses supported a causal effect of vitamin D deficiency and dementia.
• in some populations as much as 17% of dementia cases might be prevented by increasing everyo...

Possible roles of magnesium in vitamin D synthesis. Magnesium is involved in both activation and inactivation of vitamin D. Abbreviations: 1,25(OH)2D, 1,25-dihydroxyvitamin D (biologically active form); 24,25(OH)2D, 24,25-Dihydroxyvitamin D; 25(OH)D, calciferol (inactive form); D2, vitamin D2 (from nonanimal sources); D3, vitamin D3 (from animal sources); DBP, vitamin D–binding protein; Mg, magnesium; VDR, vitamin D receptors.

Up to 50% of US population is magnesium deficient. Vitamin D can’t be metabolized without sufficient magnesium levels, meaning Vitamin D remains stored and inactive for as many as 50% of Americans. In addition, Vitamin D supplements can increase a person’s calcium and phosphate levels even while they remain Vitamin D deficient...
