How well does Vitamin D3 work?
Vitamin D3 is below average for atopic dermatitis "Supplements and Natural Remedies" treatments.
What is the evidence behind Vitamin D3?
Vitamin D supplementation appears to help reduce the severity of atopic dermatitis, particularly in patients with severe cases. Studies show that taking vitamin D along with standard treatments leads to greater improvement in eczema symptoms compared to standard treatment alone.
What does the research say?
Study Summary

Adding vitamin D supplements (1600 IU/day) to standard treatment with hydrocortisone cream helped improve severe eczema symptoms in children more than using hydrocortisone cream alone. Patients taking vitamin D showed about 56% improvement in their eczema severity compared to 42% in those taking placebo.

  • Bloodwork found the root of my eczema -- severe vitamin D and iron deficiency
    April 24, 2024
    Hi all, I've posted here before, in fact, I've been actively trying to fight my eczema for about 20 years. I've been to so, so many doctors. Tried so, so many creams and pills. In Canada, our medical system is failing pretty hard and I don't know how or why but theres doctors popping up that you can pay for. So, I did (I am so lucky to be in this position that I can afford that right now) To be clear, I am not a doctor and what I am about to describe is the best of my understanding -- I am sure my doctor explained it to me in layman's terms and I am not 100% certain of any info beyond this: After some advanced bloodwork testing it came back that I am chronically low in vitamin D and Iron storage. Like, so low that the doc said she had no idea how I was functioning so well as a basic human. I had had standard bloodwork done around 10 years ago specifically looking at iron, but it was not caught. Turns out I'm reading pretty normal-healthy on the standard tests, but the iron and vitamin d 'reserves' are basically non existent. Both are triggers from eczema and both together were causing all kinds of problems for me not exclusive to my skin. I won't even get into how angry I am that despite alllllllllll the signs this wasn't caught by anyone before. Now that I know, there's so many clues. Every doctor I went to was just interested in giving me band-aid solutions or dismissed me. I was told once by a doctor that my best bet was to 'win the lottery so that I could quit my job and spend my life focusing on moisturizing my skin.' The biggest indicator that this might be your problem to is if you experience severe seasonal depression. I was a wreck every winter. Around these parts of Ontario we get little sun in the winter so everyone's mood dips a bit-- I thought I was just sensitive and taking it harder than everyone else.
  • Is a vitamin D deficiency related to eczema?
    Jan. 8, 2025
    I've seen a lot of this online. Is it true? Have been considering taking a vitamin d supplement, especially since it's very cold where I live.
  • Lack of Vitamin D
    March 31, 2024
    I've just came back from Barcelona, the weather wasn't that great since it was very windy but it was still sunny and I did still spend a lot of time out in it. On day 3 I noticed my face eczema was completely gone, I didn't wake up with any dryness either, it was like I was normal. Even my lines underneath my eyes looked faded as if they were disappearing, they won't ever disappear but they weren't as noticeable is what I mean. I'm back in the UK now and I can see the red tint coming back slightly and I'm now back to waking up with a dry face, which sucks. I always knew my eczema got better in the sun so I always had a feeling my eczema had something to do with Vitamin D and now I know for definite since I wasn't even doing anything different on my trip, I was just out in the sun. I still think that even though I've found my trigger I will still struggle with my eczema, the only way to stop me from struggling is if I move out the UK to somewhere more sunny, I've been looking for an excuse to leave anyway. I know that I could always get appointments for Light Therapy but I think I'd prefer to do it naturally with natural sun, you just don't get any here. It's funny because I know remember the story my mum told me about how I could've been born in Australia since they were planning on moving there, if I was born there I don't think I would've ever had eczema
Pregnant women taking vitamin D supplements (1000 IU daily) during pregnancy may help reduce their baby's risk of developing eczema in the first year of life, particularly if they breastfeed for more than one month.

  • Finally cured my Daughters Eczema
    Nov. 4, 2024
    My daughter started having Eczema when she was 6 months of age. Since then we have been experimenting on many things to help her and heal her. Long story short, below are the list of things we did 1. We reduced the usage of steroids as much as possible (only during big flare-ups) 2. We stopped using the cetamacragol (Vaseline + .. i dont know what else in it) and instead used Shea Butter + Black seed oil cream on her 3. Slowly we even stopped using sheabutter and only used raw and organic black seed oil on her skin multiple times in a day 4. We made sure she gets enough Vitamin D3 & K2 & Omega-3 in the form of supplements 5. We discovered the main trigger was milk and milk related products. So we stopped them and used milk alternatives. All the above steps helped us in managing her eczema and not really cure it. When it comes to curing 1. We wanted to find out the actual reason for the triggers. 2. We found that Milk, Corn & Sugar were aggravating her condition but were not really the cause 3. We wanted to go to the root cause so we started seeing if the eczema is caused because of gut leak. No. Was it because of Liver issues. No. Was it because any other organ problems. No. 4. We saw the eczema is increasing during the colder the months but greatly reduced during summer times 5. Then we suspected if it could be related to lung issues or breathing issues. And there we narrowed it down. Real Cause: During winters as we close down all the doors and windows and turn up the heating, the humidity in the house reduces greatly. This causes the dust particles in the house to loose weight become lighter ( i have this theory that in a humid place the tiny water particles binds with the dust to keep them down, i am no scientist) and start circulating within the house. This is the real trigger. This and seasons when there are more hay particles in the air. Solutions: 1. Remove all carpets from home 2. Installed good air circulation system in the house 3. Installed air-purifier in every room atleast in the sleeping room 4. Reduce the number of corners where dust can collect 5. Humidifiers everywhere set to auto-mode 6. Aroma diffuser with mix of eucalyptus oil in the bedroom while sleeping everyday. PS: I am not a scientist nor a doctor. But I don't have to be neither to look at all the possibilities and to find workable solutions. I believe in the natural ability of the body to heal when presented with the right conditions.
  • TSW WARRIORS!!! HERE'S SOME TIPS ON HOW I'M OVERCOMING !!!!!
    April 24, 2024
    Hi, I writing this in hopes that my experience can help someone struggling, do know that you will get better, I believe in you and the power of your body! english is not my strong suit, please excuse my grammar I developed TSW in august 2023 and have been dealing with it since, I'm 23y/o and female. Ive had eczema all my life and had used steroid creams all my life. I had several extreme flares in my scalp but never this bad on my body. I was in a stressful relationship and living conditions in 2023. TSW covered 95% of my body by Dec 2023 and i had no insurance. I had to stop working and when I did, I could completely relax ...I started to heal naturally. I still struggled immensely with sleep but hydrating with electrolyte beverages and taking baths would ease my discomfort. Then, I relapsed and my skin was oozing like never before from my face, neck, legs.. i was miserable... I scratched my legs so bad that I started to lose my body heat and water through them. I went to the urgent care, and they begged me to take a steroid shot, along side with my first dose of dupixent. I caved in, and man that steroid shot had me feeling like I was king of the world. I could finally walk around again and sleep, my skin stop flaking, but that lasted for only 6 weeks... lucky the dupixent off set some of the effects of my body going back into withdrawal but it was still misery. I am currently on dupixent but I am still fighting TSW symptoms... it helps a lot but not completely takes it away here are my tips 1) HYDRATE, I also went to the emergency room in dec, they treated me for severe dehydration, but really, I think it was because my kidneys and adrenals were struggling, Start the day with lemon water, 16 oz, chug it. I also know that if preparing drinks and food is too much for you, buy a pack of gatorade and drink those with your water bottles. 2) wanna see real result and relief, FAST... if you cant fast because of blood sugar reasons or you're just not strong enough, its ok, don't push yourself; but if you have fasted before please try a monofruit fast with cantaloupe( only eating cantaloupe). with in the first 6 hours my skin stopped shedding, i was in disbelief, I only made it to 24 hours, but try 72 hours and nothing further. You will cleanse your system and rejuvenate your adrenals because of all the vitamin C. 3) VITAMINS AND MINERALS.... did you know that almost half the people with eczema has a vitamin d deficiency. I went to the doctor once and my vitamin d level was a 14, the minimum is suppose to be 30, yikes. please go to the doctor and get bloodwork. If your vitamin d is low, start taking some. d3+k2 is pretty good but ask your doctor first. I also have been mineralizing my water with trace minerals 40,000 volts electrolyte drops. its natural electrolytes with magnesium your body can absorb, it's super salty, but i drink mine with lemon water. Vitamin C!! its good for your skin and kidneys/adrenals. I would say get this naturally because some vitamin companies will source their vitamin C from mold, yuck, try douglas labs or the 'now' brand, they are pretty reputable. I also would suggest cod liver oil pills. We must do everything we can to help our immune systems, if we get infections, thats when the weeping comes into play. 4) VASELINE, lotion just burned, vaseline makes me feel good... for a while i was using shea butter but that just made it worse and itchy. I swear by vaseline. Now I use vaseline and tea tree oil now,that my skin barrier is in tack, its a good way to get rid of regular eczema but I would not recommend if you are weeping or severely scratching that area. I repeat... only use tea tree oil and vaseline together when your skin is healed.... the tea tree oil helps with the scarring and minor itch... use it with vaseline it is very strong and needs a carrier. 5) WARM BATHS, when i was weeping sitting in a warm bath 4 times a day really helped. it was the only time i felt relief... sometimes i would put cut up limes in the water to help with any infection but if you are weeping, i suggest getting some antibiotics and taking tumeric pills to fight internal infections... if you don't like pills then maybe drinking some tulsi tea you can find on amazon, its antibacterial and antiviral 6) DIAL SOAP, if you can't use soaps right now I understand. I didn't use soap for a minute just warm water and occasionally lime juice(burned but was effective). Dial is antibaterial and it has been helping with my skin barrier, I thought it would dry me out but it didn't.. my skin feels strong now. 7)MOVEMENT... there was some days I dreaded the small walk to the bathroom... my skin was so crusted or cracked, i didnt even want to get up and brush my teeth, i hated looking in the mirror. if you you can't move without pain, practicing deep breathing and meditation is you best bet at helping your lymphatic system drain properly. Movement is so important to your health. it helps your lypmatic
  • Dermatolgist was useless, and how I cured my spongiotic dermatitis
    Feb. 7, 2024
    Over a year ago I developed a patch of nastiness on my left leg, just above my ankle and below the calf. As I had never had problems with my skin in the past I simply let it go and hoped it would clear up. Fast forward to the past summer and it gotten much worse. It had been transferred to the back of my left hand and was causing little puss pockets under my fingertips and around the fingernail areas of my hands. After some research I initially suspected it was Ringworm and so began a regimen of applying Clotrimazole. The rash on my leg and hand would fill and burst with yellow puss when there were flare-ups. The only thing that really helped was OTC colloidal silver. The condition continued to worsen and spread over the rest of my body, mostly on my arms and legs, with some areas of my torso and lower back. Obviously itching was spreading whatever it was that I had become afflicted with. Visits to a GP led me to trying ant-fungal medication (Ketoconazole) but when that failed I finally managed to procure an appointment with a Dermatologist. Prior to this I'd read countless testimonies of the incompetence of Dermatologists so I wasn't expecting much, and rightfully so. Long story short, they performed a punch biopsy on my hand and came back with a determination of Spongiotic Dermatitis. Stupid me actually expected the Derm to prescribe something that would cure whatever it was that had gotten under my skin. She told me I would have to 'manage' the condition. But I knew she was full of first class bullsh** because while waiting for the biopsy to come back I had been hitting the infected areas of my skin with the following and it had nearly completely cleared up from my hand while I awaited the results of the biopsy. This is my regimen and what is working for me to rid my skin of whatever it is that is causing the spongiotic dermatitis. Vitamin C crystals - ~4g per day (~$0.80/oz from Amazon) Triple Antibiotic ointment - a few times a day on the affected areas (Globe brand from Amazon) Vitamin D3 - ~3000iu Vitamin K2 - to complement the D3 Magnesium - same as above Zinc - same as above Zirtec - anti-histamine for itchiness Probiotics - generic stuff (NOW Supplements brand) The back of my left hand has pretty much cleared up. The patch on my left leg is going to take longer as I had not kept up with the anti-biotic ointment on that area because I actually figured the Derm was going to be able to prescribe a cure, as previously noted. I will report back in a month or two once my leg has cleared up further. TLDR; Dermatogist: "You have spongiotic dermatitis and we don't know a cure for it so you'll have to manage it." Me: "Hold my beer."

  • The Daisy Chain of Eczema and Vitamin D Deficiency
    Jan. 21, 2025

    Dec. 15, 2024
    I saw a post of this women who noticed her daughter's eczema cleared up after being in the sun for hours. I didn't even think of this before but could that be one of the causes for sudden eczema?
  • Vitamin D Deficiency
    Dec. 29, 2024
    Anyone have vitamin d deficiency and are in supplements? I had a pretty bad flare up recently (better now) and my derm was curious about my vitamin d levels so she got me tested. Turns out I do have vitamin d deficiency and she prescribed me some vitamin d3 supplements. I been researching about this and turns out the the researches are conflicting with each other. Some says theres direct correlation and others say there isnt. So im just curious if anyone in here has some experiences.

  • Vitamin D3!!
    April 20, 2024
    I’ve been struggling with eczema for all of my life. I had a blood test done a few years ago doctors found that my vitamin d levels are severely low. I can be quite bad with prescriptions but when I finally started taking vitamin D supplements every day I found my symptoms were essentially gone after a couple of weeks! A few google searches later I found that vitamin D has been found to be really effective in treating eczema. So for anyone looking for remedies try taking some vitamin D3 supplements😊
  • eczema healed!!
    July 21, 2024
    i just wanted to share some of the ways i healed my eczema that DIDNT include cutting out diary, gluten or sugar. my eczema a month ago was literally the worst flare up i have ever had in my 17 years of life lol. it spread all down my arms and lower legs and upper thighs. i had small patches on my chest, shoulders, armpits and a huge patch covering half of my back. it was bright red and bleeding/cracking even with drowning it in aquaphor. now it’s all healed. this was all a last resort, i’ve tried the steroid creams and prescription creams and they never worked on me, if they did i would get used to them and they’d stop working two months later. i just have white scarring from where it used to be!! :) •i started having balanced meals and not (skipping out on meals/eating junk food and calling it dinner) •i took 2 TBSP sea moss, 4 lysine, 2 zinc and 2 vitamin d3 a day •once a day i took 1 teaspoon zeolite in half cup water •i made my own moisturizer and applied 3-4 times a day (this is what i believe helped it heal so fast) with 100% beeswax, unrefined shea butter, milk thistle, burdock root, dandelion root, and calendula (tinctures u can buy online) this would heal my scratch wounds literally overnight •a shower filter!! (imo this is optional if u don’t have city water, but city water usually has high amounts of chlorine which dried out my skin a TON)
  • My personal eczema solution
    May 12, 2024
    Hey Community, Today I wanted to write this to help anyone dealing with Steroid Withdrawal and eczema from pollen and such. I personally suffer with eczema on my entire body and the flare started when i was 16 and never really went away. For a while it was maintained because of constant use of steroids until I flared again. It was hell my face looks burnt and it could also be a heat rash, right now its pollen season and my flares fluctuate. WHAT IVE USED: • Turmeric pills - curcumin is a chemical found in turmeric which gives it the anti inflammatory affect) • Vitamin D3 - Doctors have claimed that most patients with Eczema or skin diseases have a Vitamin D deficiency • Tea tree oil and coconut oil - both prevent infections, tea tree naturally disinfects the skin and eases discomfort, redness and itchiness and Coconut oil moisturizes and is nutrient dense. • Oatmeal, whether its topical or digested drink or eat plenty of it. THINGS THAT HELPED ME PERSONALLY: • Go on walks even if you’re allergic, it helps your body adjust • Get plenty of rest your skin is the largest organ therefore it needs more time to rest. • Drink water, Eczema prone skin can’t maintain proper hydration so you need to drink more water to make up for it • Keep your skin clean, shower as often as you want • Meditate, when you focus on your level of concentration you stop doing things out of habit because you are aware of your body That’s all I hope this helps ❤️ I wanted to add this too Another thing i used was body brushing and face scrubs on my body for exfoliation. Eczema prone skin cant shed dead skin cells so lightly exfoliate its best in the shower bc water helps shed.
Is Vitamin D3 Right For Me?
What is Vitamin D3?
Vitamin D is a fat-soluble vitamin that your body needs to build and maintain healthy bones. Your body can make vitamin D when your skin is exposed to sunlight, and you can also get it through certain foods and supplements.
What are the requirements for taking Vitamin D3?
Vitamin D3 might be right for you if:
  • You have low vitamin D levels

  • You have limited sun exposure

  • You have a condition that affects vitamin D absorption

  • You have atopic dermatitis (some studies suggest vitamin D supplementation may help with symptoms)

How does Vitamin D3 work?
Vitamin D helps your body absorb calcium from your diet, which is essential for building strong bones. It also supports your immune system, helps reduce inflammation, and plays a role in cell growth and muscle function.
Is it safe for children?
Vitamin D is safe and important for children. Infants and children need vitamin D for proper bone development and growth. The recommended dosage varies by age, and supplements should be given under medical supervision.
Is it safe for elderly patients?
Vitamin D is safe for elderly patients. Older adults often need vitamin D supplements as they may have reduced ability to produce vitamin D from sunlight and may spend less time outdoors. However, they should follow their healthcare provider's recommendations for dosing.
Is it safe during pregnancy?
Vitamin D supplementation is generally considered safe during pregnancy. In fact, it's often recommended as pregnant women need higher amounts of vitamin D. However, very high doses should be avoided without medical supervision.
Is it safe during breastfeeding?
Vitamin D supplementation is safe during breastfeeding. It's often recommended for breastfeeding mothers, as breast milk alone may not provide enough vitamin D for infants.
