A new study followed a diverse group of over 12,000 people to assess the long-term effects of vitamin D supplementation on incidences of dementia.
Researchers reported a 40 percent reduction in dementia risk over a ten-year period across all groups who supplemented with vitamin D.
The effect was most significant in older women due to declining estrogen, which activated vitamin D.
Vitamin D is one of the most prominent nutrient deficiencies worldwide. It’s linked to poor cognition and increased risk for dementia and Alzheimer’s disease. Vitamin D deficiency has been linked to over 100 adverse medical conditions and diseases.
Despite vitamin D’s neuroprotective properties, the role of supplementation for prevention remains a highly debated topic.
The minimal viable dose was not reported, but experts say a 1,000 to 2,000 IU daily vitamin D supplement would be a safe and solid addition to one’s brain health stack.
Experts also encourage more natural sun exposure, especially in the early morning hours when the UV/UVA rays aren’t damaging.
