Affordable Vitamin D Supplements May Lower Dementia Risk

A recent study highlights the connection between low vitamin D levels and higher dementia risk, with deficiencies linked to reduced brain volume and increased stroke likelihood. Professor Elina Hypponen of the University of South Australia notes that while evidence is strong, clinical trials are needed to confirm supplementation’s preventive effects. Vitamin D3 supplements, costing as little as 11 cents per tablet, could be a simple solution for those at risk.

For individuals like Phil O’Neill-Dwyer and Kristy Adler, whose families have been affected by early-onset dementia, the findings are particularly impactful. Phil, from England, acknowledges the challenges of maintaining vitamin D levels in darker climates, while Kristy, from Sydney, relies on supplements due to poor sunlight absorption. Both stress the importance of proactive measures to safeguard brain health.

While sunlight remains the primary source of vitamin D, supplements are recommended for older adults, housebound individuals, and those with darker skin. Typical daily doses range from 400 to 1000 IU of vitamin D3. Experts caution that more research is needed but encourage awareness of this accessible and affordable preventive strategy.
