Experts say vitamin D deficiency shows in your skin and legs - here are 6 signs
The NHS has said that around 1 in 6 adults in the UK have low levels of Vitamin D - and this can lead to a variety of skin and leg symptoms
Vitamin D, often dubbed the sunshine vitamin, is crucial for our bodies. It's instrumental in everything from maintaining bone health to bolstering immune function.
The NHS has revealed that approximately 1 in 6 adults in the UK suffer from low levels of vitamin D, which can result in rickets, bone pain and disabilities. In the UK, the majority of our vitamin D intake comes from sunlight on our skin during the spring and summer months, as dietary sources of vitamin D are scarce.
The current guidance suggests all adults and children should consider taking a daily supplement of 10 micrograms of vitamin D between October and March. Certain at-risk groups are advised to contemplate taking a supplement all year round.
However, uptake is minimal with only 1 in 6 adults reporting taking a daily supplement.
This deficiency can manifest itself in various ways, particularly on the skin and legs. What you might brush off as mere itching could actually be a sign of a vitamin D deficiency.
Identifying these symptoms early can lead to swift treatment.
Here are six primary signs of Vitamin D deficiency that can appear on the skin and legs.
Delayed wound healing.
If you're lacking in vitamin D, you may observe that wounds take longer than usual to heal. This nutrient is vital for skin cell regeneration and wound repair.
Research has revealed that Vitamin D is crucial for the creation of compounds necessary for new skin tissue growth, meaning that if you're experiencing persistent cuts, grazes, or sores, or they become infected easily, it could be a sign of low Vitamin D levels as your body's ability to heal is compromised.
Chemist 4 U has issued advice saying: "If you have a wound that won't heal, see your doctor. Whilst a vitamin D deficiency could be at fault, it's best not to make assumptions. Slow wound healing can also be a symptom of an infection, poor circulation or even diabetes."
Suffering from itchy skin?
A lack of Vitamin D can lead to dry and itchy skin, which might result in conditions such as eczema or psoriasis due to the vitamin's role in skin moisture and health maintenance. The Nutritionist warns: "Dry, itchy skin is often a sign of a vitamin D deficiency. As vitamin D is created through skin exposure to the sun and cholesterol in the skin, in the winter months, when sunlight exposure is less, people often experience dry, itchy skin attributing it to the cold weather. However, a vitamin D deficiency might be a more likely cause."
They further explain that in severe cases of vitamin D deficiency, coupled with other factors, autoimmune conditions like eczema and psoriasis can develop, highlighting the importance of early detection of symptoms. To combat this, one can include vitamin D-rich foods such as oily fish, eggs, and organ meat in their diet.
Additionally, topical vitamin D oils can be applied to areas with significant redness and itching if that's identified as an underlying issue.
Watch out for eczema-like symptoms.
There might be more to Vitamin D than just bone health – emerging studies suggest it could be a combatant against eczema. Experts delve into the vitamin's possible connections to the skin condition, with lower levels of Vitamin D potentially leading to worse bouts of eczema due to its role in managing inflammation and bolstering the skin's defences.
The National Eczema Society warned: "There has been some research into whether low levels of vitamin D trigger the development of eczema, and if taking supplements can improve symptoms. A key clinical review in 2015 proposed a link between eczema and lower levels of vitamin D, and found that vitamin D helped protect the skin barrier and suppress inflammation."
They added, "A 2018 systemic review found that children under 18 with low vitamin D levels had more severe eczema, with 67% seeing improvements after taking vitamin D supplements."
Moreover, a study featured in the British Journal of Dermatology uncovered that infants were less likely to develop atopic eczema in their first year if their mothers consumed 25mcg of vitamin D each day from the second trimester until birth. However, claims about Vitamin D's influence on the onset of atopic eczema still need stronger proof.
"Nevertheless, supplements may be beneficial. Only a very small amount of sun exposure is required to build vitamin D levels, but the UK climate provides enough sunlight only six months of the year. For that reason, NHS guidelines recommend that everyone in the UK should consider taking a vitamin D supplement from October to April, and that those at high risk of not getting enough, including all children aged 0–4 (except for babies drinking more than 500ml of formula milk every day) should take it every day, all year long."
Dull skin.
The Centre for Surgical Dermatology who has flagged dull skin as a sign of trouble, remarking: "Symptoms of deficiency may include dry, dull, or flaky skin. Vitamin D plays a vital role in skin cell growth and repair, making it essential for healing wounds or recovering from skin conditions like acne and eczema. When your skin cells regenerate efficiently, it helps maintain a smooth, radiant complexion, even during the harsh winter months."
They also note that while dry, dull, or flaky skin could indicate a lack of vitamin D, other factors such as dehydration, a poor diet, or insufficient sleep could contribute too.
Leg pain.
Vitamin D deficiency can lead to muscle weakness and bone pain, which might be why you're struggling with everyday activities like climbing stairs or getting up from a chair. This lack of vitamin D can cause leg pain, and in severe cases, it may result in bowing of the legs in children (known as rickets) or bone deformities.
If your muscles feel weak and you're experiencing bone pain in your legs, especially when pressure is applied to your shins, it could be a sign that your vitamin D levels are low.
Yale Medicine warns: "When vitamin D levels are low and the body isn't able to properly absorb calcium and phosphorus, there is an increased risk of bone pain, bone fractures, muscle pain, and muscle weakness. In older adults, severe vitamin D deficiency (levels less than 10 ng/mL) may also contribute to an increased risk of falls."
Excessive sweating.
One of the early signs of vitamin D deficiency is excessive sweating. It is often an overlooked sign. Excessive sweating, particularly on the head and face, is an early sign. Vitamin D plays a role in regulating sweat gland activity, and a deficiency can lead to overactive sweat glands.
Dr Stephanie Barrett said: 'It doesn't sound attractive and it probably doesn't feel it either. Sweating from the head is a classic first sign of vitamin D deficiency. Excessive sweating not in line with the temperature or any other related conditions should be investigated as it could be an increase of vitamin D is needed.'

Symptom that hits 'three times in 24 hours' could be Covid - as Nimbus variant DOUBLES in just one month and infections reach highest level this year
A new or persistent cough striking in a particular time frame could be a sign you have the new Covid variant sweeping through the UK. It comes as experts fear a hyper virulent new strain of the virus, dubbed 'Nimbus', could drive a wave of cases this summer. Official data, published yesterday, show the proportion of Covid tests testing positive for Nimbus has doubled in less than a month, jumping to eight per cent. While there are no signs the new strain causes more severe illness or death than other strains, experts warn there are signs its far more contagious. The rise of Nimbus, known scientifically as N.B.1.8.1, comes as scientists warn that many people's immunity from previous infections and Covid jabs has faded. Symptoms of Nimbus are thought to be very similar to previous Covid variants. These include a new or persistent cough, such as three coughing episodes in 24 hours or coughing a lot for more than an hour according to the NHS. The health service warns that having a high temperature, when you feel hot to touch on your chest or back, or shivering chills are also strong indicators. Other classic symptoms include a loss or change to your sense of smell or taste, a sore throat, and shortness of breath. Fatigue, a runny nose, body aches, headaches, loss of appetite, diarrhoea, vomiting and nausea are also potential signs you have the virus. Whilst the new Nimbus variant is thought to have similar symptoms to other strains, a doctor recently warned it can cause 'razor blade sore throat'. This can feel like a sharp, stabbing pain while swallowing, often in the back of the throat, said to Dr Naveed Asif, a GP at The London General Practice. Other potential symptoms linked to the strain are redness in the back of the mouth and swollen glands. 'However, symptoms can vary widely so vigilance is key', Dr Asif told Manchester Evening News. Other data, published by The UK Health Security Agency, show the proportion of people testing positive for the virus in general is on the rise. The number of Covid tests returning positive for any form of the virus has increased to 6.8 per cent as of June 15, the latest available data. This is up from 5.6 per cent last month and represents the highest figure recorded so far this year. NHS guidance says patients with Covid symptoms should self-isolate, while those who test positive should stay home for five days—but these are not legal requirements. Lab studies have suggested Nimbus is better at infecting human cells and dodging the immune system, making it highly infectious. Earlier this month, the World Health Organisation revealed the new strain now accounts for 10.7 per cent of Covid infections worldwide, compared to just 2.5 per cent in May. In Britain, the latest UKHSA data reveals there have been 947 hospital admissions for Covid in the week up to May 31—a slight increase of 9.4 per cent. Infection with the virus can still be deadly, especially for more vulnerable groups. The latest data shows the virus was recorded as factor in the deaths of 68 people in England in the week up to June 6. Other UKHSA data, showed that only 59 per cent of Britons in England aged over 75 had taken up the offer of a Covid vaccine. Uptake fell to just one in four among under 75s with compromised immune systems, who are also eligible for the jab on the NHS. NHS England's spring Covid vaccine drive is drawing to an end with the system closing for bookings earlier this week. Vaccine companies are reported to be in the midst of updating their shots to fit the 'Nimbus' strain. Moderna said late last month that its updated mNEXSPIKE shot will be available by the fall. Nimbus first originated from China, where it has been linked to a rise in cases and A&E visits. The variant has taken off in the US where data suggests it now makes up over a third of Covid cases, making it the second-most common variant. Nimbus as a name, for the variant, was coined by Canadian evolutionary biologist T Ryan Gregory, the mind behind many popular Covid strain names.

Chris Hoy calls for systemic change in testing for prostate cancer
NHS guidance says men over the age of 50 are at highest risk of developing prostate cancer, but Sir Chris wants to help men get screened earlier. He said: 'I was diagnosed with stage four prostate cancer at 47. By this age, my prostate cancer was advanced and could have been progressing from when I was 45 or even younger. 'With prostate cancer, the earlier you find it, the easier it is to treat. We need the system to change to enable more men to get diagnosed earlier, and stop them getting the news I got.' One option is a PSA blood test which checks the level of prostate-specific antigens in the blood, A high reading may be a sign of a prostate condition. NHS guidance says these tests are not routinely used as they are not reliable, but men over 50 can ask GPs for one. Sir Chris's comments came after Prostate Cancer UK urged the UK Government for an overhaul of NHS guidelines to encourage GPs to proactively speak to men at high risk from 45 years old. #ProstateCancer has become the most common cancer in England. However, for a disease that affects 1 in 8 men, there's still no screening programme and outdated NHS guidelines prevent lifesaving conversations with men at highest risk. ➡️ Read more: — Prostate Cancer UK (@ProstateUK) January 28, 2025 According to the charity, around one in eight men in the UK will get prostate cancer, which occurs when cells in the prostate start to grow in an uncontrolled way and, if not detected early, risks spreading. Sir Chris added: 'I believe men at highest risk, for example men with a family history like me or black men, should be contacted by their GP earlier on to discuss a simple PSA blood test that can check for signs of prostate cancer. Then if there are any issues, they can get it treated it at an earlier stage. 'I've told my story to help raise awareness about the most common cancer in men and get more thinking about their risk and what they can do, but it shouldn't all be men's responsibility. 'I've faced many challenges in my life, and going public with my prostate cancer diagnosis was certainly one of them. 'I've been incredibly lucky to have so much support from my family, friends and the general public. The kindness has lifted me up and given me a sense of purpose, and I'm committed to taking that forward and using my platform to raise awareness of the most common cancer in men and help more men at risk to come forward and get tested.' The Scottish cyclist has launched his own charity cycling challenge, Tour de 4, with the aim of changing perceptions around stage four cancer. The challenge will take place on September 7 in Glasgow with a final registration phase open for riders to sign up. Speaking about Sir Chris, Laura Kerby, chief executive at Prostate Cancer UK, said: 'His bravery and tireless work to raise awareness has already made a huge impact. 'In just a few months after Sir Chris went public with his diagnosis last year, over 286,000 people used our online risk checker to learn more about the disease, find out their own risk and learn what they can choose to do about it. 'His bravery has inspired so many men to take action, and he has undoubtedly saved lives. 'One in eight men will get prostate cancer. The earlier it's found, the easier it is to treat — but there's currently no screening programme in the UK. So if, like Sir Chris, you have a family history of the disease, or if you're black, we strongly encourage you to speak to your GP about testing from the age of 45. 'We don't think it's right that the responsibility is all on men's shoulders, so we're calling on the Health Secretary to overhaul outdated NHS guidelines so that GPs are empowered to actually start conversations with these men at highest risk.' The Department for Health and Social Care has been contacted for comment.

Report warns of ‘two-tier access' to ADHD treatment
An ADHD taskforce has reported that NHS waiting lists for diagnosis and support are unacceptably long, necessitating a system overhaul. The inability to access NHS services has led to a significant rise in unregulated private providers, creating a two-tier system and exacerbating health inequalities. The taskforce recommends timely recognition and early support for suspected ADHD across all settings, particularly schools, to prevent future adverse impacts. The report found no evidence of ADHD over-diagnosis in the UK, noting lower recognition and treatment rates compared to other European countries, with untreated ADHD costing the economy £17 billion. NHS England acknowledges the long waits and the need for improved ADHD assessment and care, with new data collection and government aims for school mental health support.
