How To Spot Vitamin D Deficiency?

Vitamin D deficiency is a condition that can affect your bones, teeth, and immune system. It has been linked to vitamin D-deficiency rickets in children as well as osteomalacia in adults. Signs of vitamin D deficiency may not be noticeable to many people. Symptoms of vitamin D deficiency include muscle aches, bone pain, chills or colds, fatigue, and loss of appetite. Muscle aches, bone pain, and fatigue are often attributed to other conditions such as low iron or vitamin B12 levels and so the underlying cause isn't treated right away resulting in a further weakening of the body's immune system with possible complications including severe infectious diseases. Since vitamin D is important for the immune system to maintain a healthy balance, vitamin D deficiency can cause an increased risk of infections.

Luckily, there are several ways to spot vitamin D deficiency so that you can get help before any serious problems arise.

According to a report published by the National Institutes of Health in 2014, 35 percent of people and nearly half of infants in the United States are vitamin D deficient. It can be difficult to tell without a blood test (more on that later). If there are any early signs of vitamin D deficiency, they are subtle. Experts say you might not show any symptoms at all.

Vitamin D deficiency, on the other hand, can cause premature aging and dry skin, as well as muscle weakness and bone fractures in severe cases.

The following subjects will assist us in determining how to detect vitamin D insufficiency and the best treatment,


What are the signs and symptoms of low vitamin D?

It can be difficult to tell without a blood test (more on that later). If there are any early signs of vitamin D deficiency, they are subtle. Experts say you might not show any symptoms at all. Vitamin D deficiency, on the other hand, can cause premature aging and dry skin, as well as muscle weakness and bone fractures in severe cases.

Here are some common signs and symptoms of low Vitamin D:

  • Feeling depressed and irritable

Sun exposure boosts the activity of the brain hormone serotonin. Low levels of Vitamin D in the body have been shown to impact the number of feel-good neurotransmitters in the brain, making you grumpy and irritable most of the time, according to studies.

  • Chronic Pain

You have aches, muscle weakness, and joint discomfort regularly. Vitamin D deficiency makes people more sensitive to pain.

  • Constant exhaustion

Even when you are well-rested, you feel tired and exhausted all of the time. You can also feel drowsy and anxious. A sufficient amount of Vitamin D in the body has been shown to promote energy levels and muscle performance.

  • Head sweaty:

Head sweating is one of the most prevalent symptoms of Vitamin D insufficiency. A sweaty forehead in newborns is frequently the first indicator of Vitamin D insufficiency.

  • Insomnia during the day:

Many studies show that patients with low Vitamin D levels are more likely to experience daytime sleepiness and other sleep disturbances.

  • Respiratory illnesses and flu attacks:

Because Vitamin D helps to reduce inflammation and regulate the functioning of immune system cells, you may be more susceptible to allergies and infections. 

  • Bone Loss

Calcium absorption and bone metabolism are both aided by vitamin D. Many elderly persons who have been diagnosed with bone loss believe they need to increase their calcium intake. They may, however, be lacking in vitamin D. Calcium and other minerals have been lost from bone, resulting in low bone mineral density. Fractures are more likely to occur in elderly adults, particularly women.

  • Hair Loss

Hair loss is frequently linked to stress and emotional issues, which are clear factors. Severe hair loss, on the other hand, could be the result of an illness or vitamin shortage. Low vitamin D levels have been related to hair loss in women, though there has been little research on this so far.

Vitamin D deficiency has been related to alopecia areata and may be a risk factor for the disease. Alopecia areata is an autoimmune illness that causes severe hair loss on the head and other body areas. It's linked to rickets, a disorder that produces fragile bones in children owing to a lack of vitamin D.

What causes sudden vitamin D deficiency?

Here are some causes of Vitamin D deficiency:

  • Sun exposure is limited.

People who are confined to their homes, such as those in nursing homes, or who do not get enough sun exposure are at risk for low vitamin D levels. According to the National Institutes of Health (NIH), some experts believe that 5-30 minutes of sun exposure twice a week is usually enough to maintain optimal vitamin D levels.

Sun exposure must, of course, be weighed against the risk of skin cancer, therefore it's better to avoid being sunburned. Keep in mind that while sunscreen, clothing, and other UV-blocking techniques can help prevent skin cancer, they can also limit your body's vitamin D production.

  • Obesity

Lower vitamin D levels are frequently linked to a weight of greater than 30. Several theories have been proposed in the scientific literature to explain why this is so. One probable explanation is that vitamin D accumulates in fat cells, therefore if one has more fat cells, there is less vitamin D in circulation. In this area, research is still ongoing to better understand the mechanism underlying the relationship between obesity and low vitamin D levels.

  • Kidney disease 

Kidney disease can lower the quantity of an enzyme required to convert vitamin D to a form that the body can use. A deficiency can occur if your body is unable to convert vitamin D into its useable or "active" form.

  • Skin color 

Vitamin D deficiency is more common in people with darker skin tones. This is because darker skin contains more melanin, a pigment that absorbs a large portion of the sun's rays before triggering vitamin D production.

  • Age

Our skin becomes less efficient at producing vitamin D as we age, which can lead to low levels.

  • From Medications

Certain medications can impair your body's capacity to convert vitamin D into its active form, resulting in a deficit.

Here are a few of them:

Laxatives, steroids are a kind of anabolic steroid (such as prednisone), drugs that reduce cholesterol (such as cholestyramine and colestipol), anti-seizure medications (such as phenobarbital and phenytoin), a tuberculosis treatment, and a weight-loss medication

  • Bariatric surgery 

By modifying the digestive system surgically, bariatric surgery can aid weight loss in some people. Your intestine may be less capable of absorbing vitamin D if you've had bariatric surgery.

  • Certain chronic illnesses

Specific chronic illnesses are frequently the problem when it comes to low vitamin D levels. Cystic fibrosis, Crohn's disease, and celiac disease, for example, can impair the ability of the intestines to absorb enough vitamin D into the bloodstream, resulting in low circulating vitamin D levels, which means less of it is available for different areas of your body to use.

The most accurate way to measure how much vitamin D is in your body at any given time is the 25-hydroxy serum level. A healthy person will have a reading of 20 ng/mL or higher, and if you are deficient then it can be as low as 12 ng/ml.

What happens when vitamin D is too low?

You may have low vitamin D if you always seem to get sick, no matter what measures you take, or if your illnesses seem to last longer than they do in other individuals vitamin D status is best evaluated by measuring the circulating serum 25-hydroxyvitamin D [25(OH)D] concentration. There are many vitamin D deficiency factors that cause severe complications because it is too low. Some examples include:

- Decreased bone density in adults, which can lead to a higher risk for bone fractures.

- Increased susceptibility to colds or other infections due to compromised immune system function.

- Pain and tenderness in the joints.

- Abnormal growths of vitamin D deficient bones, such as bowed legs and scoliosis.

- You might have pregnancy complications such as preeclampsia, low birth weight, and gestational diabetes.

- You may have brain fog, like the severe feeling of forgetfulness.

In children:

- impaired calcium absorption can lead to bone abnormalities and tooth issues. This is because vitamin D helps the body absorb enough minerals for healthy teeth and bones. Without vitamin D, a child may not be able to fully use the vitamin D present in their diet.

- children under age five who are vitamin D deficient may be more likely to develop asthma, allergies, or respiratory infections. This is because vitamin D plays an important role in protecting against these health problems by shaping immune cells and boosting immunity.

Does low vitamin D cause low iron?

Even though you've probably never heard of this one, there's an extremely clear connection between both Vitamin D and Iron. Surprisingly, the association between Vitamin D and Iron may be mutual, as evidence reveals that they are receptors for one another. You can't absorb iron effectively if you don't have enough vitamin D, and you can't have enough iron if you don't have enough vitamin D.

Fortunately, research has shown that keeping my Vitamin D levels in the Optimal Range, as measured by In-Home Vitamin D Blood Spot Testing, was not a role in my iron deficiency. Nonetheless, the correlation was fascinating to researchers, who felt it was important to discuss with patients who may be suffering from both Iron Poor Blood and low Vitamin D levels and are unsure why they are experiencing these symptoms. Although, because anemia isn't defined by a lack of iron, part of the problem may be that they haven't been diagnosed.- based on a researcher.

Here's a brief breakdown of iron and vitamin D relations.

  • Iron is required by the human body, particularly by the liver, which also processes Vitamin D.
  • Meat, supplements, and vegetables are the main sources of iron.
  • Iron deficiency is quite frequent all around the world. People who are pregnant, have dark skin, are vegans, and live in underdeveloped nations.
  • Some people get minor nausea from low-cost iron supplements, but some high-cost Iron supplements cause far less nausea.
  • Iron and Vitamin D are synergistic, meaning that raising one typically raises the other. Because low levels of one are often correlated with low levels of the other, synergism occurs even when neither of them is clinically deficient.
  • Women who do not menstruate (due to oral contraceptives or aging) had higher iron and vitamin levels.

Does low vitamin D cause joint pain?

Vitamin D deficiency and joint pain are connected because joint pain is one of the signs of vitamin D deficiency. Until recently, joint discomfort was not usually linked to a vitamin D insufficiency. The association between joint pain and vitamin D levels is now well understood by most doctors and other healthcare professionals.

Vitamin D regulates calcium and phosphorus levels in the blood, keeping bones and teeth healthy and firm. One of vitamin D's main tasks is to absorb calcium and stimulate bone formation. Vitamin D works in tandem with calcium to help build and maintain healthy bones and joints. Muscle pain is linked to low vitamin D, but it is less common than joint pain.

When the skin is exposed to sunshine, unlike most other vitamins, our bodies can produce vitamin D on their own. It activates vitamin D so that it may be utilized throughout the body. Although vitamin D is well known for its role in bone health, it is also suspected to play a role in brain development, muscle function, and immune function.

Evidence indicates that low vitamin D levels lead to the risk of developing Osteomalacia, or softening of the bones, is a condition caused by insufficient levels of phosphate, calcium, and vitamin D, as well as poor calcium absorption. Brittle bones and weak muscles are another possible side effect of vitamin d. It usually affects the lower back, pelvis, and hips, and the pain is usually worst at night or when you put weight on the affected bones. Morning back discomfort is thought to be caused by osteomalacia, which is caused by a vitamin D shortage.

Vitamin D could potentially serve an anti-inflammatory impact in cartilage inflammation (osteoarthritis) according to research. Vitamin D supplementation was found to be useful in reducing inflammation in osteoarthritis of the knee, according to the study. However, more research is needed on the impact of vitamin D in slowing the course of cartilage loss.

Vitamin D is necessary for bone formation and strength. This vitamin is deficient in a large number of people. Vitamin D deficiency can be avoided by spending time outside in the sun, eating vitamin D-rich foods, and taking a vitamin D supplement.

What prevents the absorption of vitamin D?

Vitamin D is a nutrient that your body requires to meet a range of key health demands, such as maintaining normal neuron and immunological function and promoting correct bone development. If you don't absorb this vitamin effectively in your small intestine, you may develop a deficit. Fat-absorption abnormalities, the presence of certain chronic diseases, and the impact of gastric bypass surgery are all possible causes of vitamin D absorption problems.

Let's discuss what prevents the things that prevent your body to absorb vitamin D.

The latitude where you reside. Because of the low angle of the sun is higher latitudes, the amount of vitamin D–producing UVB light reaching the earth's surface decreases in the winter. From November through February, for example, little if any vitamin is created in people's skin tissue in Boston. UVB exposure is also limited by short days and clothing that covers the legs and arms.

Pollution in your neighborhood. UVB rays are scattered and absorbed by carbon particles in the air caused by the combustion of fossil fuels, wood, and other things. Because ozone absorbs UVB light, breaches in the ozone layer could be a source of pollution that boosts vitamin D levels.

Your use of sunscreen. Because sunscreen protects against sunburn by filtering UVB rays, it is theorized that using it lowers vitamin D levels. However, because few people use enough sunscreen to filter all UVB rays or use it inconsistently, the effects of sunscreen on our vitamin D levels may be minor. A well-known Australian study found no change in vitamin D levels between persons who were randomly allocated to use sunscreen or a placebo cream over the course of one summer.

Your skin tone and hue. Melanin is a pigment that gives skin its dark color. It competes with a component in the skin that kick-starts the body's vitamin D production for UVB. As a result, to synthesize the same quantity of vitamin D, dark-skinned persons require more UVB radiation than light-skinned people.

Your skin's temperature is one of the most important factors to consider. Vitamin D is produced more efficiently by warm skin than by chilly skin. As a result, if it's a sunny, hot summer day, you'll produce more vitamin D than if it's a cold one.

Your body mass index. Because fat tissue absorbs vitamin D, it's been suggested that it could serve as a vitamin D rainy-day reserve, providing the vitamin when consumption or production is low. Obesity is linked to low vitamin D levels, according to research, and obesity may impact vitamin D bioavailability.

Your liver and kidneys. Because the ill liver isn't creating enough bile, several types of liver disease can cause vitamin D absorption to be reduced. Other types can't or only partially perform processes necessary for vitamin D metabolism. Bioactive vitamin D levels tend to correlate with kidney health, therefore bioactive vitamin D levels decline as kidney disease progresses until the level is undetectable in end-stage kidney disease.

Your age Older people have fewer levels of the material in the skin that UVB radiation transforms to the vitamin D precursor than younger people, and there is experimental evidence that older persons are less efficient vitamin D makers. However, the data on vitamin D levels from the National Center for Health Statistics contradicts the popular belief that vitamin D deficiency is a major issue among the elderly. There is no significant difference in levels between middle-aged and elderly adults.

What happens if vitamin D deficiency is not treated?

Vitamin D deficiency can lead to many conditions. It is important to know that vitamin D deficiency can be treated with dietary supplements, and by being more aware of vitamin sources in our diet such as milk products or fortified foods like cereals, juices, and soy beverages. Vitamin D stores are also built up during the summer months when UVB radiation boosts vitamin production. along with the Vegan Nutrition store has the best supplement for Vitamin D deficiency, namely the Valupak Vitamin D3.

Obesity can exacerbate vitamin D deficiency because fat cells store vitamins and can not release them efficiently. Vitamin D deficiency and obesity, according to researchers, "interact synergistically" to increase the risk of diabetes and other metabolic problems.

According to some studies, those with severely low vitamin D levels are roughly three times more likely to die of heart failure and five times more likely to die of sudden cardiac death. However, because there isn't proof of a clear correlation between higher vitamin D levels and decreased cardiovascular risk, experts say it's too early to say whether taking supplements can help your heart.

If left untreated, the condition will deteriorate. Incontinence in women, according to a 2012 research review published in International Journal, vitamin D deficiency can lead to failure in the pelvic floor that is, the hammock of muscles that supports the bladder, vagina, uterus, and rectum—and lead to urinary incontinence as well as, potentially, fecal incontinence in women. Maintaining adequate vitamin D levels may be just as important as completing pelvic floor exercises for women who have trouble controlling their bladders.

Most people do not commonly experience side effects with vitamin D unless too much is taken. Some side effects of taking too much vitamin D include weakness, fatigue, sleepiness, headache, loss of appetite, dry mouth, metallic taste, nausea, vomiting. The current adequate vitamin d intake recommended dietary allowance RDA doses of vitamin D recommended in 1998 by the United States Food and Nutrition Board of the Institute of Medicine is 200 IU/day (5 μg/day) for infants, children, and adults males and females up to age 51 age.

In general, if all symptoms and indicators of vitamin D insufficiency are ignored, they will develop, potentially leading to serious problems. A vitamin D supplement from our Vegan Nutrition Store will help not to make it worse.

What is the best treatment for vitamin D deficiency?

Vitamin D is necessary for a wide range of bodily processes, from supporting strong and healthy bones to keeping your immune system in good shape. Getting adequate sunlight on your skin provides the majority of your body's Vitamin D. This is a struggle for many people, which is why recent government guidelines urge taking a daily Vitamin D3 pill. It has also been demonstrated to help the immunological system. Taking Vitamin D during the winter months, when you're more likely to be sick, can help maintain your immune system, which is important for fighting off infections.

Vitamin D insufficiency has been related to breast cancer, colon cancer, prostate cancer, heart disease, depression, weight gain, and a variety of other illnesses. These studies suggest that those with higher vitamin D levels have a decreased risk of disease, but they don't prove that a deficiency of vitamin D causes disease or that supplementing with vitamin D reduces risk. Vitamin D insufficiency can be treated with supplements or by becoming more conscious of vitamin sources in our diet, such as milk products or fortified cereals, juices, and soy beverages. During the summer, when UVB light promotes vitamin production, vitamin D stocks are also built up.

We have a great vitamin D supplement at Nutracity that can help you to treat your condition, namely Valupak Vitamin D3. Our Vegan Supplement Store is a 100% plant-based supplements with vitamin C to support the absorption of calcium for bones, Vitamin D for healthy muscles and joints, vitamin E to support long life and naturally sweetened with pineapple fruit extract.


Vitamin D is more than just a vitamin, it's a hormone. It has been shown to have an impact on the immune system as well as our weight and muscle health. If you're deficient in vitamin D don't wait for symptoms or warning signs before getting treated because vitamin deficiency can lead to serious problems! For those wanting to take vitamin D supplements, vitamin D is necessary for a wide range of bodily processes, from supporting strong and healthy bones to keeping your immune system in good shape. Getting adequate sunlight on our skin provides the majority of our vitamin D but many people struggle with this during winter months which is why recent government guidelines urge taking vitamin d-capsules. The best treatment for vitamin D deficiency is vitamin d-capsules from our vegan nutrition store at Nutracity.
