A Glamour UK report describes five symptoms that may be associated with vitamin D deficiency: frequent illness, fatigue, bone pain, muscle weakness and depression. It cites a government diet and nutrition survey estimating deficiency in nearly one in five UK adults aged 19 to 64, rising to nearly one in three in winter. The symptoms can have other causes, and a person cannot confirm deficiency from symptoms alone.
Glamour UK has published a report outlining five symptoms that may be associated with low vitamin D, alongside estimates from a government diet and nutrition survey that nearly one in five UK adults aged 19 to 64 have a deficiency, rising to nearly one in three during winter. The figures describe a population-level estimate; the symptoms discussed in the report do not establish that an individual has a deficiency.
The five signs named in the report are frequent illness, fatigue, bone pain, muscle weakness and depression. The article draws on interviews with nutritionists, dietitians and general practitioners, as well as studies it cites. It presents these signs as possible associations, not a checklist that can diagnose low vitamin D.
The report says vitamin D helps the body regulate calcium and phosphate, nutrients involved in keeping bones, teeth and muscles healthy. The NHS is cited for that role. The article also describes vitamin D as involved in immune function, while the experts it interviewed discuss possible links with mood and energy.
Evidence varies by symptom. The article cites research associating deficiency with fatigue and muscle weakness, and says low levels can impair calcium and phosphate absorption, with possible effects including bone pain. It also notes research into depression and vitamin D, while acknowledging that more research is needed to establish the relationship. Frequent illness is described as a possible contributing sign, not proof that someone is deficient.
Reading the Five Symptoms Carefully
The report puts a common health concern into context: its cited survey suggests deficiency affects a substantial share of UK adults aged 19 to 64, with a higher estimate in winter. For readers experiencing fatigue, aches or low mood, that may prompt a discussion with a clinician, particularly if symptoms persist or interfere with daily life.
But the symptoms are not specific to vitamin D deficiency. Fatigue, muscle weakness and low mood can have many causes, and the article does not provide evidence that any one symptom predicts a low level. Treating the list as a diagnosis could lead readers to overlook other explanations or assume supplements are needed without individualized advice.
The distinction matters because the source combines survey prevalence, expert comments and studies examining associations. Those types of evidence answer different questions: a survey estimates how common deficiency is in a population, while an association does not by itself show that low vitamin D caused a symptom. The report offers readers possible signs to discuss, not a test result or individualized medical assessment.

Vitamin D, Sunlight and Seasonal Risk
Vitamin D is a fat-soluble vitamin that the body can produce when skin is exposed to UVB rays in sunlight. The article cites the NHS for its role in regulating calcium and phosphate. It also says dietary sources include fatty fish and eggs, with fortified milk among the examples given by an interviewed nutritionist.
The experts quoted by Glamour identify low sunlight exposure and an unbalanced diet as possible contributors to deficiency. They point to spending much of the day indoors and living where sunlight is limited as factors that may increase risk. The report says UK sunlight is generally too weak for vitamin D production during autumn and winter; it identifies April to October as the period when sunlight may support production in the UK.
The article includes an expert estimate that 15 minutes of daily sun exposure may be enough, but the supplied source does not explain how that estimate varies by person, location, skin tone or conditions. It should not be read as individualized medical or sun-safety guidance. The report also quotes a GP recommending supplements broadly in the UK, but does not include the full government guidance or discuss individual dosing.
““It’s often called the ‘sunshine vitamin’ because our bodies produce it in response to sunlight.””

Limits of the Symptom Evidence
The supplied report does not give the survey’s fieldwork dates, sample size, testing method or definition of deficiency. It also does not provide the underlying survey tables, so the estimates of nearly one in five adults and nearly one in three in winter cannot be checked against further detail here. The figures are reported as estimates, not as a current measurement of every UK adult.
The report’s symptom evidence is also incomplete in the material provided. It refers to several studies but does not give full citations for all of them, and association alone does not establish cause. The article itself says further research is needed on vitamin D and depression. It remains unclear from the supplied text how much any particular symptom changes the likelihood of deficiency.
The source excerpt ends while discussing supplements. It does not contain complete advice on daily intake, supplementation during pregnancy, risks of excessive intake, or who should seek testing. Readers should not infer a personal dose or diagnosis from the article’s symptom list.

Discussing Symptoms and Testing
Readers concerned about persistent symptoms or vitamin D levels can discuss them with a healthcare professional, who can assess possible causes and whether testing or a supplement is appropriate. The supplied report does not state that a new government review, policy change or follow-up survey has been announced.
For a fuller account of UK recommendations, the relevant next step is to consult current NHS guidance and the complete Glamour report, including its sections on intake and supplementation. Any future update to the survey figures would need to specify the measurement period and how deficiency was defined so readers can compare the estimates over time.

Key Questions
What five possible signs of low vitamin D does the report list?
It lists frequent illness, fatigue, bone pain, muscle weakness and depression. These symptoms can have other causes and cannot confirm deficiency on their own.
How common does the cited survey say vitamin D deficiency is?
As reported by Glamour UK, the government diet and nutrition survey found deficiency in nearly one in five UK adults aged 19 to 64, rising to nearly one in three during winter. The supplied source does not state the survey’s fieldwork dates or testing details.
Can these symptoms tell me whether I have a deficiency?
No. The article describes possible associations, and symptoms such as fatigue or low mood have many potential causes. A healthcare professional can advise whether assessment or testing is suitable.
What sources of vitamin D does the report mention?
It describes sunlight exposure as a way the body produces vitamin D and names fatty fish, eggs and fortified milk as dietary sources. Its excerpt does not provide complete supplement guidance or a personal dose.
