Vitamin D for Cognitive Decline and Parkinsons

Two new studies published this year have shown that vitamin D  is beneficial in preventing two diseases commonly seen in the elderly.

One study, which was published by P. Knekt in the Archives of Neurology, followed   3,173  Finlandians for  29 years. The results showed that  high vitamin D levels do provide protection against  Parkinson’s.

The other study published in the Archives of Internal Medicine by DJ Llewellyn found  a substantial decline in mental cognition in patients with serum 25 (OH) D levels  less than   25 nmol/L, which is below the recommended average of  50 nmol/L.    Those with low levels of vitamin D were compared to a group with levels higher than 75 nmol/L.
