“Research in northern Britain shows older adults and minoritized ethnic groups maintain low vitamin D levels year-round, with little boost from summer sun exposure.”
A study of nearly 300 participants in northern Britain found that vitamin D levels remain consistently low throughout the year in older adults and people from minoritized ethnic backgrounds. Despite assumptions, summer sunlight did not produce a meaningful increase in vitamin D levels among these groups.
The findings challenge the common belief that summer sunshine alone can correct vitamin D deficiencies in vulnerable populations.
