Unusual symptoms of vitamin D deficiency can lurk unnoticed until serious health problems crop up. Even doctors frequently miss these 10 signs of very low levels.
Flu is sometimes referred to as “Vitamin D deficiency disease”. Now, COVID may be proving to be a similar virus according to researchers. Avoiding vitamin D deficiency symptoms by keeping blood levels of this fat-soluble vitamin optimal can be lifesaving especially for the immunocompromised and the elderly.
Dr. John Cannell of the Vitamin D Council and one of the most preeminent Vitamin D researchers in the world today, has identified that vitamin D helps produce the antimicrobial peptides that protect against viruses like the flu and coronaviruses.
This is why people are more prone to complications during seasons when Vitamin D producing sunshine is minimal or nonexistent at some latitudes, or people are too bundled up to get enough skin exposed in the first place.
Scientific research bolsters Dr. Cannell’s suggestion that vitamin D deficiency is why people get the flu. A study published in the journal Nature Immunology further explains how vitamin D protects us by properly activating T cells, an important part of the immune system:
When a T cell is exposed to a foreign pathogen, it extends a signaling device or ‘antenna’ known as a vitamin D receptor, with which it searches for vitamin D.
This means the T cell must have vitamin D or activation of the cell will cease. If the T cells cannot find enough vitamin D in the blood, they won’t even begin to mobilize.
This is troubling given that vitamin D levels were reported by the Archives of Internal Medicine in 2009 to have plummeted for every single age, race, and ethnic group in the United States over the past two decades.
Low Vitamin D Levels Can Lurk Unnoticed
Vitamin D deficiency is such that it can lurk unnoticed until it is too late and you are already sick. Another challenge is that it takes time, usually at least several weeks, to raise vitamin D levels. As a result, a few days of taking supplements is not going to cut it. This is true especially if you have a serious deficiency challenge to overcome or already have the flu.
Below are 10 signs that vitamin D is likely a problem and potentially a serious deficiency that needs to be addressed immediately. If any of these symptoms are an issue for you, a simple and inexpensive vitamin D blood spot test can be ordered online. It can be used in the privacy of your home to determine if your vitamin D levels are in the danger zone.
Best Foods to Address Deficiency
If low levels do indeed need to be addressed, the best whole food-based supplement to bring vitamin D levels into optimal range without the danger of overdosing is unheated, unprocessed cod liver oil (where to find).
Natural vitamin D drops from sheep wool are also a good idea temporarily if levels must be raised quickly.
Two other foods extremely high in Vitamin D include fish roe and lard from pastured animals.
Wild roe contains about 17,000 IU of Vitamin D per tablespoon and pastured lard (vetted source) has 10,000 IU per tablespoon according to tests conducted by the Weston A. Price Foundation. This is nearly as much as you would get during a day at the beach in a bathing suit.
I purchase my fish roe at gourmet stores. Additive-free brands can also be purchased online.
Vitamin D Deficiency Symptoms Usually Blamed on Something Else
Be aware of these symptoms, some of them quite strange, that are frequently blamed on something else. Since Vitamin D deficiency is so easy to address with lifestyle and dietary modifications, it is a good idea to consider this “low hanging fruit” approach first.
1. Chronic Pain
Bone pain and chronic pain, in general, is a subtle symptom of serious vitamin D deficiency. Don’t take this symptom lightly! Get your vitamin D levels checked and address the problem.
A study conducted by Greg Plotnikoff, MD, senior consultant with the Allina Center for Health Care Innovations, makes the point. 150 people living in Minneapolis who came to a health clinic complaining of chronic pain were tested for vitamin D levels. Virtually every single one, 93%, suffered from extremely low vitamin D. “The group with the lowest levels of vitamin D were white women of childbearing age,” Plotnikoff says.
2. Muscle Weakness
Here’s a shocker most folks don’t realize: most muscle weakness issues are low vitamin D related. The National Institutes of Health reports that a person suffering from a vitamin D deficiency will have trouble with proper muscle function.
This extremely common skin issue is an autoimmune disorder that many don’t realize can be vitamin D-related. This nutrient plays an important role in the treatment of psoriasis. Psoriasis gets worse over time and spreads, so even if you only have a little spot on your elbow or knee, get your vitamin D levels checked, and be sure to be taking a daily dose of high vitamin, unheated cod liver oil.
4. Constant Fatigue
Vitamin D is necessary for the body to produce energy. If you are constantly tired or must lean heavily on that morning cup of Joe to get going in the morning, best to play it safe and get your levels checked.
No, it’s not all in your head! Feelings of hopelessness can be related to nutritional D deficiency. The Vitamin D Council reports that vitamin D is critical for the brain to produce the happy hormone serotonin.
Some folks only suffer from depression during winter months, known as Seasonal Affective Disorder (SAD). This condition is caused by lack of sun exposure and hence vitamin D during this time of year.
6. Sweaty Head
This is quite possibly the weirdest symptom of vitamin D deficiency. Old-time doctors apparently used to ask new mothers if their heads were sweatier than normal in order to pinpoint a lurking vitamin D deficiency as reported by NDHealthFacts.
A sweaty head is also a subclinical symptom of rickets, possibly the most prominent and dangerous form of vitamin D deficiency in children.
7. Constant Respiratory Problems
This warning symptom is related to flu as a vitamin D deficiency disease. If low vitamin D puts people at risk for flu, it stands to reason they would be at risk for other respiratory problems too, and possibly on a chronic basis. Studies have demonstrated that vitamin D protects against respiratory illness particularly in children, who require hospitalization most frequently due to bronchiolitis and pneumonia.
Scared of COVID or the flu? The most proactive step you can take short of frequent beach jaunts is to make sure your Vitamin D levels are high by taking a daily dose of cod liver oil!
8. Hypertension and/or Cardiovascular Disease
My mother helped resolve high blood pressure issues with a daily dose of high vitamin cod liver oil. Her success in this regard is in line with the Vitamin D Council which recommends adequate vitamin D levels in order to avoid this silent, symptomless killer. 1 out of every 3 Americans and 4 in 10 worldwide suffer from this serious condition.
In addition, the National Institutes of Health has identified vitamin D deficiency as a risk factor that can lead to congestive heart failure.
9. Chronic Kidney Disease
Chronic kidney disease is a growing health concern. It is a primary and powerful predictor for premature cardiovascular disease.
Not surprisingly, given that cardiovascular disease itself indicates a likely vitamin D deficit, research indicates that those that suffer from chronic kidney disease are also D deficient in a big way.
10. You are an Infection Magnet
If you suffer from one infection after another, it is wise to get those vitamin D levels checked pronto. As described above, T cells which are an important part of the immune system, are properly activated by vitamin D. If D levels are low or even undetectable, adequate and effective immune response to an infection in the body will be severely hampered.
Do you suffer from one or more of these 10 symptoms of low vitamin D? Did you know that these signs are usually blamed on something else? Did you suspect a vitamin D deficiency might be the true reason? Have you ordered a blood spot test kit or started taking unheated, high vitamin cod liver oil? What did you find out from testing and what have your results been?

Two major symptoms of Vitamin D which mostly doctors miss among elder patients are tiredness and exhaustion, as they might consider it as a symptom of aging, however, it might well be a serious vitamin D deficiency. Constant fatigue usually occurs due to lack of phosphorus and calcium being absorbed into the system,which in turn can trigger joing and bone pain in elderly.
I have Hashimoto which makes me a risk for Vit D deficiency..I asked my physician for over a yr and he never would do it. I felt tired, weak, muscle cramps, headaches and a pressure feeling, SAD ….finally he did it with me getting upself. I am 12. Normal 30-100. I felt good on 6000IU for the first 2 wks. I think it was psychological. After that I did not have as much fatigue or depression but my cramps and sinus and headachy feeling, brain fog are still there. It has been alittle over 2 mo. He said to come back in 3 for a reck. He was going to put me on 50,000 IU a wk but said if I wanted to take it I could. I had already started myself on 6000 IU a day and continued that with Mag. and Vit K…why am I not feeling much better . I am still having anxiety as well. Plus I read that low Vit D can cause a proliferation of sinus tissue causing polyps. I have had sinus issues for about 3 mos or more. They did get better but still I am suffering and do not know if this is related to allergy or can this be from low Vit D
I got another sinus infection this fall and the flu last winter. Every year a cold lingers months as a sinus infection. We eat farm raised pastered organic meat milk and vegies, minimal grains, take cod liver butter oil mix and try to get outside daily but its getting colder up here. I know you do not recommend any supplements but I believe we need to get more vitamin D. Is radient life a good source for vitamin D? other recommendations?
Have you had your Vitamin D levels tested? The spot tests you can order online are very convenient now. We use the Dropi cod liver oil as of about a year ago. Fish eggs are an amazing source of vitamin D. Just a Tbl has about 17000 IU of D … about the same as a midday dose of vitamin D in the summer.
