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.
