A new animal study from Japan suggests that vitamin D may help clear the brain of amyloid beta, a toxic protein-like compound that accumulates in the brains of Alzheimer’s patients, according to RealAge.com.

This animal study further validates the results of a previous study done in human Alzheimer’s patients. In the human study, vitamin D was given along with curcumin (found in the spice turmeric) and the combination appeared to stimulate the immune system in a way that helped clear the brain of toxic amyloid beta.

The new animal study suggests that vitamin D alone may be able to clear the brain of plaques. Even more impressive–the lab animals that received vitamin D were able to remove a significant amount of amyloid beta buildup in their brains, literally overnight. It appears that vitamin D may somehow regulate production of transporter proteins that carry amyloid beta across the blood-brain barrier and out of the brain.

The most effective way to obtain this vital nutrient is directly from the sun. Natural sunlight is the best source of vitamin D!

UV sunlight is the fuel that enables the body to make vitamin D, but how long should you stay in the sun to optimize your Vitamin D without sun protection?

Skincare experts at SkinHealth Technology, LLC have developed a patented, new concept that enables you to attain vitamin D development 100% naturally–without damage to the skin. To accurately gauge the necessary length of time in the sun, simply apply one of their Natural Vitamin D UV Activation Sensors to skin or clothing. When the sensor turns red and the sun symbol disappears —it’s time to apply sunscreen or get out of the sun.

They recommend exposing uncovered arms and legs to bright, mid-day sun between the hours of 10:00 am and 4:00 pm. (Exposure of 25% or more of the body’s total skin surface is necessary and protection of sun sensitive areas, like the face, is advised.)
