Alzheimers and Vitamin D

It never ceases to amaze me just how much the Vitamins we consume affects the overall health of our body. The deficiency of a single Vitamin or mineral can have debilitating effects on long-term health. Vitamin D is found in three forms in your body. First as Vitamin D3, when you ingest it. Next as Vitamin D25 which is the hydroxylated version. Finally as D125 which is the hormone version of the Vitamin.

Vitamin D is essential for bone health and also for your immune system to function. It also helps your body absorb calcium. Interestingly, it has been linked to Alzheimer’s. Research revealed that specific mechanisms regulated by the Vitamin D helped clear amyloid-beta. Amyloid beta is the same abnormal protein found in your brains that causes Alzheimer’s. The misfolding of the protein in your brain is what creates sticky plaque, in much the same way as your arteries get clogged, and block the space between brain cells. Over time this leads to a host of ailments of the brain including Alzheimer’s.

Typically, your body has something called a macrophage. The role of the macrophage is to consume these misfolded proteins and destroy them. It was Vitamin D that was helping your body produce the macrophages that were destroying the protein. In those patients who had Alzheimer’s, this process was ineffective. The research team was apparently able to establish the difference between the manner in which macrophages expressed themselves in healthy individuals versus those that had Alzheimer’s. More research needed to be done before they could find a way to control the process through medical intervention. Of course, there is a more straightforward way – just make sure that you consume sufficient quantities of Vitamin D.
