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.

3.  Psoriasis

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.

5. Depression

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?

    Thank you so much!
    What a fast reply!
    Yes, I’ll do that. I’ll get the liver, roe and sun.
    We do at least have good South African sun.

      Just be sure to sun for short periods at midday because that is when the rays are strongest and contain the Vitamin D rays.

    Hi. If I live in a country with no cod in our waters, no Amazon.com, no fclo in even the best health-shops, and a currency that is now down to twenty-bucks to one dollar… what can I do instead of fclo??

      Eat liver and fish roe. Also, get short doses of midday sun on as much of your body that you can expose. Never burn, just sensible sunning for the purpose of Vitamin D production via the skin.

    Hi everyone, today I want to share about this vitamin d deficiency. When I was pregnant, in initial stage I got vitamin d deficiency. My doctor suggested to eat fruits which have vitamin d and to sit under the sun for an hour everyday to absorb some quality and quantity vitamin d. Because if my vitamin d level didn’t increase then my baby could have less weight while birth. So I took it seriously and I got a healthy baby girl. During that time, I read many articles regarding this and I want to share one link among many: doctorshealthpress.com/general-health-articles/vitamin-d-deficiency-women

    I never know about these risk factors for vitamin d deficiency. When I came to know about the deficiency of vitamin d in me, I used to study many articles regarding this. Some risk factors are:
    1. Dark Skin
    2. Veganism
    3. Digestive Conditions
    4. Obesity
    5. Limited Sun Exposure

    Both my husband and myself had our levels checked via blood test … We were both scary low .. hubs was a 12 and mine was a 6 .. minimum level from that lab was 30 … it has been super hard to raise our levels. it took us almost 2 years at 50kIU a week to get close to the minimum. Though we both do have some issues with our Vitamin D receptor genes so that is likely part of the problem.

      Recently neglected my daily D intake of 1000 IU. After labs, my physician prescribed 50,000 IU once a week for two months, then she will repeat labs. She is an excellent physician, do I’m confident my levels will be back to normal at next lab check.

    It is best to have your levels tested before supplementing but the odds are most of us will benefit. A recent study found that the current recommendations (RDA) are 10 times too low!

    I appreciate your information!! I have a question about cod liver & krill oils, before I order one or the other. Saw your reference for a source to purchase called radiant Life & I have posed this same question to them? but in case they do not reply, I’m quite sure I could benefit from more K3 since I’ve taken calcium & d for 30 years & still have osteoporosis. 🙁 but! the smell of cod liver oil once nearly made me gag, let alone the taste! which specific brand would NOT do either to someone with a sensitive nose & pallet?
    Thanks for your reply (and potentially, products you recommend)

      “Calcium” as a supplement is a sales-scam Try eating vegetables instead!

      Are you still recommending fermented cod liver oil?

      Oct 23, 2015 at 1:01 pm

      Yes, I take it myself as I have since it first came out around 2007. The “proof” put forth wasn’t very convincing to me especially in light of the favorable results we’ve had with it in my family. Seemed more like a personal ax to grind IMO.
