Vitamin D And The Skin Barrier Function
Calcitriol is known to modulate the proliferation and differentiation ofkeratinocytes.5 For this reason,vitamin D3 analogues have been used to normalize the hyperproliferation present inpsoriatic skin.24
In experiments with mice, Hong et al. observed a faster recoveryof the skin barrier in the group treated with narrowband UVB phototherapy, observinghigher histological levels of filaggrin and involucrin in this population.Phototherapy-induced vitamin D was considered responsible for accelerating the epidermalbarrier recovery.66
Keratinocytes express high levels of 1-hydroxylase. The product of this enzyme,1,252D promotes in vitro differentiation of keratinocytes. In micethat lack this enzyme, there is a decrease of involucrin, filaggrin and loricrin -keratinocyte differentiation markers – essential for the cornified envelope formation.Mice that are defective in VDR have an increased transepidermal water-loss because ofthe epidermal barrier breakage. 1,252D was found to be essential fornormal epidermal differentiation, probably by inducing proteins and mediating calciumsignaling in the epidermis, steps that are necessary for the generation and maintenanceof the skin barrier.67
Studies on psoriasis indicate that the topical treatment with calcipotriol,1,252D analog, increases VDR expression in keratinocytes. Effects ofcalcipotriol in epidermal keratinocytes proliferation and differentiation were morepronounced than its effects on dermic inflammation.68
Get The Facts: Vitamin D
Can taking vitamin D help reduce the severity of eczema symptoms?
Although there is still some debate, experts are increasingly suggesting vitamin D supplements for their eczema patients. To find out why, we talked to Dr. Peter Lio, assistant professor of clinical dermatology and pediatrics at Northwestern University.
In general, Dr. Lio said, I recommend vitamin D supplementation to my eczema patients. While I do not think that all of them are necessarily deficient, I do think that many of my patients, if not most, have a relative vitamin D insufficiency.
Indeed, according to a National Health and Nutrition Examination Survey, 40% of adults in the United States and 61% of children under the age of 21 are low in vitamin D.1, 2 Other sources estimate that three out of four Americans and one billion people worldwide have vitamin D insufficiency.3 Groups at particular risk of having low vitamin D include women, Black Americans and anyone with an increased body mass index.4 Inadequate vitamin D is believed to be due to: dietary factors decreased time spent outdoors living in geographic locations where natural sunlight may be limited air pollution and not eating enough vitamin D rich foods like salmon, tuna, or fortified orange juice, milk and yogurt.
Vitamin D, Dr. Lio explained, plays a number of roles in health and disease prevention. For eczema, the main factor seems to relate to immune system regulation, with research showing that vitamin D can:
It’s Easy To Check If Your Levels Are Sufficient But Many Americans Are Vitamin D Deficient
“According to a 2009 report published in the Archives of Internal Medicine, 77% of Americans have a deficiency in vitamin D levels, affecting their overall health,” explains New York City-based registered nurse Rebecca Park.
“Vitamin D deficiency results from lack of exposure to sunlight , impaired vitamin D absorption , medications that impair vitamin D absorption, and low dietary intake,” added Dr. Shainhouse. “Individuals at highest risk are those who are institutionalized, the elderly, or those with more darkly pigmented skin.”
Park added that people over the age of 50 have less ability to synthesize vitamin D from sunlight and are at a greater risk of osteoporosis and arthritis, fractures, muscle weakness, and cancers.
“Testing for Vitamin D deficiency involves a simple blood test,” said Dr. Shainhouse. “The lab should measure the level of bioavailable vitamin D, which is D3 . There is a range of normal, low normal, moderate and severe deficiency.”
Your doctor can test you annually.

Causes Of Hand Eczema
Eczema and nutritional deficiency
Eczema is a systemic disease that can express itself in many parts of the body. Eczema caused by environmental irritants and allergens may have specific causes. However, often the causes are broad systemic reactions, located where they are for reasons that may never be clear. Such causes include stress, hormonal conditions, genetic causes, and nutritional deficiency. However, limited research has been done on eczema and nutritional deficiency, and there has been no research performed about eczema on the hands.
Two studies link generalized eczema to vitamin D deficiency and a lack of antioxidants in peoples food. But none of these studies are conclusive, and none were focused on hand eczema.
In general, theres a correlation between low vitamin D levels and increased severity of eczema symptoms. More research is needed to confirm that this observation is more than a mere coincidence.
Subjects in a third study were less likely to develop eczema when their diets included foods rich in antioxidants — like broccoli and spinach. Again, more research is needed to verify and understand these results.
General causes of eczema
Work-related contact with products can be a significant cause of hand eczema. Examples of triggering products include the following:
How Does It Help
How exactly can vitamin D help ease eczema symptoms?
- It may boost the part of your immune system that controls the health of your skin barrier. This barrier acts as the first line of defense against the outside world. People with eczema have abnormal skin barrier function, but vitamin D receptors help regulate specific proteins that strengthen your skin barrier.
- Vitamin D helps combat inflammation. Eczema is considered an inflammatory condition, so Vitamin D helps by bumping up molecules that cool down inflammation.
- Another plus for vitamin D is that it supports your bones. One of the not-so-great side effects of steroid medications commonly given for eczema is they can adversely affect bone health over time. People with eczema may have a higher risk of developing fractures, and vitamin D could help build stronger bones.

Does Gut Health Affect Eczema
Gut health and eczema Recent studies have drawn a link between eczema and the health of the skin microbiome. However, there’s also evidence that gut health is a major factor in the cause and treatment of eczema. Research has shown that gut health is closely associated with the appearance of eczema in childhood.
Does Vitamin D Deficiency Cause Eczema
Research studies sponsored by the Vitamin D Council, , have made a coherent argument that low vitamin D levels have increased the incidences of asthma, eczema, psoriasis and an immune molecule linked to other allergies and they have attempted to link successful treatment of asthma, eczema, and psoriasis to increased levels of vitamin D3. The Vitamin D Councils research correlates conclusions that having high enough levels of vitamin D3 may reduce your risk of developing eczema and psoriasis and the prevalence of eczema and psoriasis flareups. And that people with normal to higher levels of vitamin D3 will help manage eczema flareups and they will have fewer skin infections.

Vitamin D: What Are The Health Benefits For Eczema
The link between vitamin D insufficiency and deficiency and atopic dermatitis may not be as clear as some research has proposed. No argument that vitamin D promotes calcium and phosphate absorption, and is needed to maintain the growth of healthy bones, muscles, and increase immunity from some serious diseases. A study in the British Medical Journal found that increasing vitamin D intake reduces the risk of colds, flu and other respiratory infections like pneumonia but there are conflicting research results on whether vitamin D levels really have a bearing on eczema and psoriasis. But does vitamin D deficiency really impact eczema? In this blog, we try to sort out fact from fiction about vitamin D benefits and eczema prevalence, severity, treatment, and prevention.

What Is Vitamin Ds Role In The Body
Also known as calciferol, vitamin D is a fat-soluble vitamin that is important for skin and bone health. This nutrient helps the body absorb calcium in the stomach, promoting healthy bones. Vitamin D also helps reduce inflammation and promotes a healthy skin barrier, both of which are important for managing eczema. Recent research also suggests that low doses of vitamin D are associated with certain cancers and cardiovascular diseases.
This vitamin can be found in foods or taken as a supplement. The body can also make its own vitamin D when the ultraviolet rays from sunlight hit the skin.
There are two types of vitamin D D2and D3. Vitamin D2 mostly comes from plants. Vitamin D3 is made by your body or obtained from animal products like liver or fish. Both forms of vitamin D can also be taken as dietary supplements.
Eczema And Vitamin D Deficiency
For a long time, scientists thought vitamin D mainly played a role in bone health. However, more recent studies have found that it is involved in other processes, such as immune system regulation and new cell growth , especially in the skin.
Now researchers believe that skin conditions, such as eczema and psoriasis, are connected with vitamin D deficiency. Because the skin barrier is disrupted in eczema, researchers have suggested that vitamin D and the cells that make it also play a role in eczema development. The link to psoriasis is more established, with topical vitamin D analogs commonly used as treatment for psoriasis.
Some studies associate lower serum vitamin D measurements with a higher risk of developing eczema, particularly in children and adolescents. Other studies found mixed results regarding the effects of vitamin D levels on the severity of eczema symptoms for example, some findings associate lower levels with worse symptoms, and others show no connection between vitamin D levels and eczema symptoms. More research needs to be done to clarify the link.
A few factors might influence the association between lower vitamin D levels and eczema. For example, studies have found a higher prevalence of eczema in people who live in higher-latitude locations that gets less sun exposure throughout the year. The weather in these areas can also affect eczema risk.

The Truth About Vitamin D And Eczema
Have you ever wondered how important Vitamin D can be for eczema? This week, we take a look at a variety of studies that examine vitamin D and eczema. Well also discuss how much of it you may need in order to heal eczema properly and effectively.
Please keep in mind that although these tips and information have worked for several eczema sufferers, I am in no way a medical professional. If youre experiencing severe eczema or have a topical infection, it is always best to seek medical advice immediately.
If you are not producing enough vitamin D, your immune system can weaken which can cause the skin barrier to break down and the chances for skin infection to increase. It is no wonder why many eczema sufferers skin gets worse in the winter. In addition to the dry air created by indoor heaters, its possible theyre not getting enough vitamin D.
For a while now, a common treatment for severe eczema has been to expose skin to ultraviolet light, which essentially stimulates the production of vitamin D in the skin.
However, recently the consumption of vitamin D has shown to be just as effective in treating and healing eczema. In fact, several studies have been conducted to determine the levels of vitamin D present in the skin of those with eczema, as well as the effects of vitamin D in treating eczema.
