TL;DR
A government diet and nutrition survey cited by Glamour UK found that nearly one in five UK adults aged 19 to 64 had vitamin D deficiency, rising to nearly one in three in winter. Fatigue, bone pain, muscle weakness, frequent illness and low mood can be associated with low vitamin D, but none confirms a deficiency; testing and clinical advice may be needed.
A government diet and nutrition survey cited by Glamour UK found that nearly one in five UK adults aged 19 to 64 had vitamin D deficiency, rising to nearly one in three during winter. The report lists fatigue, bone pain, muscle weakness, frequent illness and low mood as possible signs, while stressing that symptoms alone do not establish a deficiency.

The five signs highlighted are frequent illness, fatigue, bone pain, muscle weakness and depression or low mood. The report says vitamin D plays a role in immune function and helps the body regulate calcium and phosphate, nutrients involved in maintaining healthy bones, teeth and muscles. These symptoms are not specific to vitamin D deficiency and can have other causes.
Bone and muscle symptoms have a clearer connection to vitamin D’s role in the body. The report cites Yale Medicine as saying low levels can interfere with calcium and phosphorus absorption and may be associated with bone pain, fractures, muscle pain and weakness. It also references a 2018 study linking low vitamin D status with increased risk of falls and weakness close to the body’s trunk.
Evidence concerning tiredness, infections and mood is less conclusive. The article cites studies associating deficiency with mental and physical fatigue, and research exploring possible links with depression and anxiety. It says further research is needed to establish the mood connection. A symptom—or a cluster of them—cannot by itself show that someone has low vitamin D.
Why Winter Deficiency Matters
The figures suggest that low vitamin D is common among working-age adults in the UK, with the reported proportion higher in winter. Vitamin D supports calcium and phosphate regulation, so a confirmed deficiency can matter for bone and muscle health. Recognising persistent symptoms can prompt someone to seek medical advice, but treating symptoms as proof risks missing another cause.
Season and exposure to sunlight are relevant because the body produces vitamin D when skin is exposed to UVB rays. The report says UK sunlight may not be strong enough for vitamin D production during autumn and winter. Diet and supplements may also play a part, but decisions about supplementation should take account of individual circumstances and clinical guidance.

How Sunlight and Diet Affect Levels
Vitamin D is a fat-soluble vitamin that the body can produce through UVB exposure. According to the NHS, as quoted in the report, it helps regulate calcium and phosphate. Foods named as sources include fatty fish, eggs and fortified milk; the article also identifies low sun exposure and an unbalanced diet as possible contributors to deficiency.
The report features comments from nutritionists, dietitians and a GP, and describes the survey figures as findings from the most recent UK government diet and nutrition survey. However, the supplied account does not give the survey’s fieldwork dates, testing method or the precise definition used for deficiency. Those details are needed to interpret the prevalence figures fully.
“It’s often called the ‘sunshine vitamin’ because our bodies produce it in response to sunlight.”
— Jessica Sepel, nutritionist and JSHealth Vitamins founder, as quoted in Glamour UK
Symptoms Cannot Confirm Deficiency
The supplied report does not specify when the government survey was conducted, how deficiency was measured, or how many people were included. Its figures should be read as the survey results reported by Glamour UK, not as a current individual diagnosis. The report also does not provide a single symptom pattern that can reliably identify low vitamin D.
Research linking vitamin D to fatigue, infection risk and mood includes associations that do not establish cause and effect. The article itself says more research is needed on depression and related mood effects. Anyone with persistent or concerning symptoms should seek advice from a qualified health professional rather than self-diagnose or rely on a supplement alone.
When to Seek Individual Advice
The report recommends considering sunlight exposure and vitamin D-containing foods, while noting that sunlight may be insufficient for production in the UK during autumn and winter. People concerned about deficiency can discuss their symptoms, risk factors and whether testing or supplementation is appropriate with a clinician or pharmacist. There is no follow-up survey or new clinical guidance identified in the supplied material, so the next step depends on individual circumstances.
Supplement dose and suitability should be checked against professional advice, particularly for people who are pregnant, have a health condition or take medication. Avoid treating the article’s general comments about sunlight or supplements as a personal prescription.
Key Questions
What are the five possible signs of low vitamin D?
The report lists frequent illness, fatigue, bone pain, muscle weakness and low mood or depression. These signs can have other causes and do not confirm a deficiency.
How common was vitamin D deficiency in the figures cited?
The government survey cited by Glamour UK found deficiency in nearly one in five UK adults aged 19 to 64, rising to nearly one in three during winter. The supplied material does not state the survey dates or measurement method.
Can symptoms alone tell me if I have a deficiency?
No. The symptoms described are not specific to vitamin D deficiency. A health professional can advise whether an assessment or test is appropriate.
What can affect vitamin D levels?
The report names limited sunlight exposure and an unbalanced diet as possible contributors. It also lists fatty fish, eggs and fortified milk as foods containing vitamin D.
Should I start taking a vitamin D supplement?
Supplement needs and doses vary. Ask a clinician or pharmacist for guidance, especially if you are pregnant, have an existing health condition or take medication.
