Both vitamin D and curcumin, the pigment that gives spicy turmeric its yellow-orange color, have been shown to help fight Alzheimer's disease independently, and it appears they may provide even more powerful punch when applied together.
Curcumin prevents the spread of amyloid protein plaques, which are thought to cause dementia. Amyloid plaques, along with tangles of nerve fibers, contribute to the degradation of the wiring in brain cells. This study revealed that vitamin D3 together with curcumin may help stimulate your immune system to clear your brain of amyloid beta, thereby helping to prevent Alzheimer's.
