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. We’ll 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 you’re 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, it’s possible they’re not getting enough vitamin D.
For a while now, a common treatment for severe eczema (especially during the winter months) 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.
Studies with Vitamin D and Eczema
Randomized controlled trial using vitamins E and D supplementation in atopic dermatitis
In 2011, a study  was conducted to assess the effects of vitamins D and E supplementation in eczema patients. 45 eczema patients were included in a randomized, double-blind, placebo-controlled experiment where each were treated for 60 days. Separate vitamin D groups and vitamin E groups each saw an improvement in the intensity and amount of eczema around 35%. But together, when 1600 IU of vitamin D3 and 600 IU of vitamin E were given together, patients improved by 64%!!
The study revealed that there were notable effects and benefits in supplementing vitamin D for eczema patients and even more so when given together with vitamin E.
Eczema (Atopic Dermatitis) treated by 1600 IU of vitamin D
In December 2016 a systematic review  was conducted in order to compile results from various past studies on vitamin D and eczema.
They looked at four randomized controlled trials, including the one mentioned just above, and they were able to discover that serum vitamin D levels were generally lower in eczema patients, but especially so in children. And all studies they reviewed indicated that vitamin D helped to improve a patient’s eczema overall.
But How Much Vitamin D Should You Take?
Although many studies have shown that vitamin D can be beneficial in the treatment of eczema, another question might be: how much vitamin D does one need to heal safely and effectively?
Prior to supplementing vitamin D, it’s important to note that in summer conditions or hot weather, it’s possible to generate close to 20,000 units of vitamin D just from exposure to the sun. However, during the winter months, it’s difficult to generate anything close to that amount let alone the recommended dosage.
Vitamin D Dose Recommendations
Generally, 35 IUs of vitamin D per pound of body weight is the recommended average dose.
Check out the chart below for more information:
|Below 5||35 units per pound per day|
|Age 5 – 10||2500 units|
|Pregnant Women||5000-10000 units|
Although these are general recommendations, testing your blood for vitamin D really is the only reliable way to know how much vitamin D you or your little one needs.
ALWAYS speak with your physician before starting any sort of supplementation.
Where to find Vitamin D?
- Vitamin D is naturally found in fatty fish and fish oils, as well as small amounts in beef liver, egg yolks and cheese. Not all oils are created equal, so be sure to read about fish oil for eczema to learn about the safest oils.
- Foods fortified with vitamin D like some dairy products, orange juice, soy milk, and cereals.
- Sun, sun, sun…oh and, SUN!
- As available, safe and inexpensive tablets such as these Viva Naturals High Potency Vitamin D3 Jennifer Roberge, our founder and editor, swears by liquid drops and loves this brand for her family. She adds the drops to her kid’s oatmeal and cereal or any breakfast food and it doesn’t change the taste.
Again, if you are vitamin D deficient or think you might have to supplement with higher doses, it’s always best to see your doctor before doing so.
