Vitamin D Supplement Support for Vitamin D Deficiency

Many people know vitamin D as the sunshine vitamin because it’s produced by the body in response to exposure to the sun. Very few foods naturally contain vitamin D and it’s difficult to get enough vitamin D from your diet alone, which is why a good vitamin D supplement is recommended to treat vitamin D deficiency.

Vitamin D

Vitamin D is a fat-soluble vitamin and is an essential nutrient for a healthy body.

People are often confused when they search for a Vitamin D supplement but it says Vitamin D3 supplement on the label. The reason is, vitamin D3 is the preferred form of vitamin D.

Vitamin D is mainly found in two different forms, namely vitamin D2 and vitamin D3.

Vitamin D2 (ergocalciferol) - Comes from plant sources and is often found in fortified foods.

Vitamin D3 (cholecalciferol) - Found in animal-sourced foods and is produced by your skin in response to sunlight.

Both vitamin D2 and vitamin D3 are effectively absorbed into the bloodstream. However, they are metabolized differently by the liver.

Vitamin D3 is more effective than vitamin D2 at increasing the levels of vitamin D in your body.

Vitamin D3 Supplement

Your physician will normally recommend you take a vitamin D3 supplement when you have a vitamin D deficiency.

Normal Vitamin D Level

The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D blood test.

Most physicians agree that a level of 20 nanograms/milliliter to 50 ng/mL is a normal vitamin D level for healthy people.

A physician will normally take the overall health, and symptoms of a patient into consideration, as well as if the patient falls into a high risk category (such as obesity, dark skin, or has a medical disorder such as celiac disease) before making a decision on whether or not the patient has a vitamin D deficiency.

Vitamin D Deficiency Causes

According to a study that was done a quite couple of years ago, 41.6% of adults in the US are vitamin D deficient. This number goes up to 69.2% in Hispanics and 82.1% in African-Americans. It’s estimated that worldwide about 1 billion people are vitamin D deficient.

“People who avoid the sun or who cover their bodies with sunscreen or clothing should include good sources of vitamin D in their diets or take a supplement.”
- Office of Dietary Supplements, part of the National Institutes of Health (NIH)

The single biggest cause of low vitamin D levels or a vitamin D deficiency is a lack of sufficient exposure to the sun.

Your body makes vitamin D when your skin is directly exposed to the sun. Exposure to sunshine while indoors, through a window, will not produce vitamin D. In addition, cloudy days and shade will severely limit the amount of vitamin D your body can produce.

But, spending a lot of time in the sun has its own health risks.

According to the Office of Dietary Supplements, part of the National Institutes of Health (NIH):

“Despite the importance of the sun to vitamin D synthesis, it is prudent to limit exposure of skin to sunlight in order to lower the risk for skin cancer.”

Certain people are more prone to a vitamin D deficiency

  • Older people - As you grow older, your body becomes less efficient at making vitamin D.
  • People with dark skin - A dark skin limits your body’s ability to make vitamin D from the sun.
  • Obese people - Body fat can prevent or hinder vitamin D from getting into the blood.
  • Certain disorders - Vitamin D is a fat-soluble vitamin and its absorption depends on the gut’s ability to absorb dietary fat. Fat malabsorption is associated with several disorders such as Crohn’s disease, celiac disease, inflammatory bowel disease and cystic fibrosis.

Vitamin D Deficiency Symptoms

Here are some common symptoms that may suggest you have low vitamin D levels or a vitamin D deficiency.


Several studies have found a possible link between depression and low vitamin D levels, especially among older adults.

Many people comment that when they go without sunshine for a period of time that they get depressed but once they are exposed to sunshine again that it lifts their mood.

Impaired brain function

New research suggests that a vitamin D deficiency may lead to a significant decline in the brain’s ability to remember and learn.

Getting sick often

Vitamin D plays an important role in your immune system. If you’re often sick, especially with colds or the flu, it’s possible that your immune system has been compromised and low vitamin D levels may a contributing factor.

Feeling tired all the time

Excessive fatigue or exhaustion, even with enough sleep, is often a sign of a vitamin D deficiency.

Hair loss

The most frequent cause of hair loss is a hereditary condition where hair loss is common in the family. It normally follows a predictable pattern where, as they grow older, men develop a receding hairline and bald spot and women develop thinning hair.

Hair loss is often also attributed to stress. However, excessive hair loss, especially over a short period of time, with no previous history, may be the result of a vitamin D nutrient deficiency.

Slow healing wounds

Slow healing wounds may be a sign that you have a vitamin D deficiency.

Sore muscles

Sore muscles may have many different causes but there have been studies done on people suffering from chronic pain where it was found that the vast majority of them were vitamin D deficient.

Weak or brittle bones

Vitamin D is needed to maintain strong bones as it helps the body to absorb calcium (one of the main building blocks for bones).

If you don’t get enough vitamin D you may develop osteomalacia where your bones become weak, thin and brittle.

A lot of research is being done on vitamin D and how a vitamin D supplement can support the health of your body.

Here are some preliminary statements from the Office of Dietary Supplements, part of the National Institutes of Health (NIH).

According to the NIH:

Vitamin D status could affect cancer risk.

“Strong biological and mechanistic bases indicate that vitamin D plays a role in the prevention of colon, prostate, and breast cancers.”

Furthermore, potential benefits of vitamin D or a vitamin D supplement, as suggested by the NIH, include:

“A growing body of research suggests that vitamin D might play some role in the prevention and treatment of type 1 and type 2 diabetes, hypertension, glucose intolerance, multiple sclerosis, and other medical conditions.”
