Vitamin D and Chronic Sinusitis

Can Vitamin D cause symptoms of Chronic Sinusitis that do not go away or come back despite antibiotic treatment? Thank you so much!!

Diana Lee



Hi Diana,

I'm assuming that you mean can vitamin d DEFICIENCY contribute to chronic sinusitis?

But since you asked this question on the Vitamin D Side Effects page, do you mean "Can TAKING Vitamin D cause sinusitis?"

I'm not sure which one you are asking. Also, have you had your vitamin d levels checked? If so, what are they?

If you are taking vitamin d, then how much are you taking?

Also, Diana, while doctors in practice still assume that sinusitis is a bacterial infection, when actually CULTURES are taken of the organisms, sinus infections are VERY VERY frequently found to be FUNGAL infections- and therefore are not GOING to get better with antibiotics!!!

So, let me know what your real question is and I can help you figure out these sinus infections.. They usually have a simple cause and there are a couple of tricks to help get rid of them and keep them away!

RE: Vitamin D causes Chronic Sinusitis
by: Anonymous

I'm sorry, I guess I wasn't clear on the question. Due to being low on Vitamin D from a blood test my doctor took, (I don't have the numbers) she put me on 1800IU of Vitamin D. I began taking that in 2007. About the same time, I began having symptoms of dry nasal passages. I have had 2 sinus infections since that time. I wondered if it were because of taking the Vitamin D.

Could a side effect of Vitamin D be sinus issues?

I can't thank you enough for the information you provide on this site concerning the supplement Magnesium when taking Vitamin D. I have the symptoms you have listed for Magnesium deficiency.

Thanks so much for your attention to this matter.

Much more likely to be vitamin d deficiency...
by: Kerri Knox, RN- The Immune Queen!

Hi Diana,

So, I'm a little more clear now. But I think that my answer is going to surprise you!

OK. I do NOT believe that vitamin d could be causing you to have sinus infections. What I think COULD be happening, though, is your Vitamin D Deficiency might be contributing to your sinus infections!

I'm betting that you are thinking, "But I got that fixed, I've been taking 1800 IU's since 2007."

Well, unless you have had a repeat level, I'm betting that you are still severely deficient. 1800 IU's is a 5 year old child's MAINTENANCE dose, NOT an adult dose for Vitamin D Deficiency Treatment!!

Have you had a level drawn since then Diana?

i agree!
by: Anonymous

I have noticed that everytime I take vitamin D, i get a sinus infection exactly as she describes which lasts for a week or two. There must be a connection. It begins the day of or after I take vitamin D and I usually take vitamin D in high doses (50,000 iu).

I read somewhere that the inactivated form of vitamin d has a reverse effect than its activated form, so there might some science to this.

Vit D is reducing my symptoms of allergies and sinus pain and infections
by: J~

Hello, I am finding that after taking the higher levels of vitamin D (for deficiency)- that my chronic sinus pain/infections and seasonal allergies are CLEARING UP!!

These allergy/sinus issues are problems that I have tried to live with for YEARS. I was just online searching to see if my clearer sinuses might be the result of taking vit D. And there IS science to show that vitamin D deficiency can be related to allergies, asthma and sinus infections.

I am very excited to find that I may have finally found the solution and the source of the problem that has been causing my miserable sinus ailments!!! My sinuses have been pain free and almost completely clear since taking higher doses of vitamin D!!! :)

Vita D Deficiency and Sinus
by: Anonymous

I have had chronic sinusitis and recently started taking 50,000 units a week of Vitamin D prescription due to D deficiency and have not had sinusitis at all for the first time in many many years!

Vitamin D and Allergies
by: Anonymous

I am always amazed that everytime I start taking D 2000 iu a day how my allergies get better. I may take a little more in the next little while cause it hasn't taken all symptoms away but definitely made a huge improvement. Whenever I stop it comes back.

D or Magnesium for geographic tongue
by: Anonymous

So been taking d 2000 to 3000 iu daily but also incorporated 200 mg of magnesium and doing epsom salt baths once weekly, I had a geographic tongue before taking all of these and now it's almost all gone my tongue is looking pretty healthy. So what did it, the d vitamin or magnesium.

Thanks, Love your website by the way. Thanks for being online.

You need both so why does it matter.
by: Kerri Knox, RN- The Immune Queen!

Why does it matter which one did it? You took both and you NEED both and I don't recommend taking vitamin d without magnesium, so your question is simply NOT important! You need to take both for good health, obviously, and obviously your geographic tongue was due to nutritional deficiencies, so why would you stop? You need them both so don't think about it too much and enjoy your healthy tongue.

If you want to worry about something, worry that you are still not getting nearly enough vitamin d. 2000 IU's is a maintenance dose for a 50 pound child and is likely still leaving you extremely deficient. Please read my page on Vitamin D Therapy to see the step by step instructions that you need to follow to get your vitamin d level up. If you've not had your vitamin d level actually checked, then you're likely in for a shock.

Amazing D
by: Dennis

I read these comments with great interest. Vitamin D has changed my life. After 40 years of suffering from severe sinus infections, battling Eczema, and taking Prednisone to battle them both, I stumbled on a University of San Diego Medical School study about Vitamin D and its effects on Eczema. That study led me to the Vitamin D Council website. From there I had my blood checked for levels of Vitamin D. They were off the charts low.

I started at 6000 IU per day with Calcium. Within about 6 weeks my Eczema started to go away. A second blood test showed improvement, but was still low. I increaed my intake of Vitamin D3 to 10,000 IU daily. Six months later, I am totally off Predinsone and my Eczema is about 95% controlled. What has this to do with sinus infections. Well, those have also subsided about 50%. There have been other positive effects from this Vitamin D supplementation, but I don't want to sound like I am trying to sell the stuff. Increasing my Vitamin D intake along with calcium has been the most important thing I have ever done in my life. If you have not been to the depths with sinus issues and skin disorders, you cannot understand. Test your blood for Vitamin D and get your levels up. You will be amazed.

INTERESTING! I've had chronic sinusitis since 1986. Even though I had sinus surgery 1&1/2 years ago (for two things, and I'm glad I had it done) it didn't cure the sinusitis. Constantly swollen sinus like a clamp over my nose. Puffy eyes, throbbing face etc. I notice elevation changes and slight weather changes. Makes me very tired and it's hard to think strait. I also have a Vit D deficiency based on testing.

There's much more to my long term health challenges but these are the two big ones that remain. I was just thinking how I need to get back to a Vit D supplement and also the sun lamp room at my chiropractors office which I haven't had the energy to do. Out of curiosity I typed in online Vit D and Sinusitis and found this site.

If the low vitamin d is causing the sinusitis, I might be able to push my self more to treat it. I read an awesome book a year ago on D and this guy experimented with high doses and amazing results. Just hard to keep up with something when you don't see improvement. Off to start again. THANKS SO MUCH for the info.

Vitamin D/Magnesium?
by: CarolB

Just re read the other posts. You're saying not to take D without Mag? What form of Mag? I've tried magnesium before in many forms for some of the challenges I've had and never noticed any benefit. I read a couple of good books on D a year ago and they didn't mention adding magnesium. Would appreciate your take on the matter. THANKS!

re-read the thread
by: Kerri Knox, RN- The Immune System Queen

Please re read the thread. I point you to the Vitamin D Therapy page twice in the thread. If you read this page thoroughly and go to the links provided, it will take you to pages explaining this.

BTW, we eat lots of salads, veggies and green smoothies. I've also used Transdermal mag with no noticeable benefit. I do have other symptoms that could be mag related. I'm off to get some chelated mag now that I've read or re read it all. Maybe it's the combination of mag and d3 that allow it to work. Thanks for the info!

Vit D and allergies
by: Diane C.

I had a severe Vit D deficiency, too, and was put on Vit D supplements of 50,000 IU weekly until I was able to decrease that dose to 2000 IU daily.

Once my Vit D blood level tested 'within normal limits,' my allergies and subsequent sinus infections have disapeared. It's miraculous!!!

I've even discontinued taking Zyrtec daily after many years of needing it. No more ENT visits for me!

I thank my PCP for having tested my Vit D level. :-)

Just sharing my story.

40+age: vitamin D absorption issue and ruination problem
by: Jimcreative

In January 2015 I was found with vitamin D level of about 28.8. My doctor prescribed me drops and suggested me to take 20 drops daily. However right from the beginning while I was sleeping at night I had severe pain in my male organ and felt the urge to pass urine. Unfortunately the urine could not come with full pressure and I had to live with too much of discomfort for several hours. I then reduced the dose to half and ultimately I started skipping my dose. I tried a couple of times more to resume the original dose but had the same result. I also felt significant pressure on my kidneys as well

Now today I have received my new report which shows the vitamin D level as 32.1 and calcium as 9.4mg/dl

My doctor has prescribed me tablets with 1mcg One-Alpha and osteocare. Not sure if it will work. Anyone can you please help me to understand why it's like that and how can I get the level corrected

(It is also pertinent to note that I also have chronic problem of post nasal dripping, sore muscles of calves and shins, which all of sudden disappear the day I started using vitamin D..)
