Newcastle Study Finds 65-Plus Adults Keep Low Vitamin D Year-Round in Nearly 300 People
2 articles · Updated · SciTechDaily · Jun 6
Summary
More than half of adults aged 65 and older had insufficient vitamin D levels, and rates were even higher in minoritized ethnic groups, with little improvement even during summer in northern Britain.
Researchers said weaker northern UVB exposure, darker skin pigmentation, age-related declines in vitamin D production, and factors such as clothing and sunscreen can all limit summer recovery.
The findings point to a public-health gap: researchers called for clearer guidance, routine primary-care discussions and appropriate supplementation rather than relying on seasonal sunlight alone.
Next-phase work will examine personalized, culturally appropriate diet and healthcare strategies to improve vitamin D status in higher-risk groups.
If summer sun fails high-risk groups, is our public health reliance on sunlight fundamentally flawed?
Beyond supplements, what changes in food policy or urban design could solve this health crisis?
Vitamin D Deficiency Persists in Northern Britain Despite Summer Sun: Insights from the 2026 Newcastle Study
Overview
A major 2026 Newcastle University study found that vitamin D deficiency remains widespread in northern Britain, especially among older adults and people from minoritized ethnic backgrounds, even during summer when sunlight should help. This persistent problem is caused by factors like reduced skin synthesis with age, limited outdoor activity, and insufficient dietary intake, made worse by inconsistent food fortification and low supplement use. Despite public health campaigns and recommendations, current UK strategies have not improved vitamin D levels for at-risk groups. The report calls for stronger, year-round interventions, including mandatory food fortification, better supplementation programs, targeted testing, and clearer public messaging to address this urgent health issue.
