What Is Vitamin D For And 14 Low Vitamin D Symptoms

what is vitamin d for and low vitamin d symptoms

Meeting vitamin D requirements is essential throughout our life. But what is vitamin D for and why is it so important to fix low vitamin D symptoms as soon as they show up?

 

Does anyone remember the “cod liver oil torture” when we were children? Even though it was, by far, the most hated “medicine”, this remedy is loaded with essential nutrients, included large amounts of vitamin D, indispensable to growth and to the good functioning of our body.

What is vitamin D for?

 

Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and for multiple other biological effects, such as immune, cardiovascular, respiratory, bone and muscle regulation, brain development, fertility and anti-cancer effects.

Vitamin D works like a hormone, and every cell in our body has a receptor for this vitamin.

 

A few facts and curiosities about vitamin D:

 

  • Vitamin D gets synthesized by cholesterol, when our skin is exposed to the sunlight;
  • In humans, the most important compounds in this group of vitamins are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol).
  • Vitamin D deficiency is actually widespread – around 1 billion people all over the world (and more than 40% of the US population) have low vitamin D levels.
  • being overweight, having dark skin, using sunscreen, being vegan, staying indoors are all risk factors for vitamin D deficiency.

 

Vitamin D requirements

 

It often happens that we are not aware of having a vitamin D deficiency. In order to check the level of vitamin D, we need a particular blood test, which is often prescribed to individuals at risk, like the elderly.

The ideal vitamin D concentration is 30-60 ng/ml. A 10-30 ng/ml concentration is insufficient, while a concentration lower to 10 ng/ml shows an actual vitamin D deficiency.

Vitamin D dosages are often expressed through International Units (IU), and the requirements of this vitamin varies throughout our lifetime as follows:

babies from 0 to 12 months = 400 IU;

children from 12 months on = 600 IU;

adults = 1000 – 1500 IU;

elderly = 2300 IU.

 

Some researchers suggest that an adult’s requirements are a lot higher and are around 3000 IU of vitamin D a day (3500 for elderly people), even though it is always advisable to seek advice from a medical professional.

14 Low Vitamin D Symptoms

low vitamin d symptoms

 

#1 – becoming ill more often

One of the main functions of vitamin D is to boost the immune system, in order to cope with and battle viruses and bacteria efficiently. If you often become ill, you nearly always have a cold or a flu, then you are likely to suffer from vitamin D deficiency.

Research has proven the link between insufficient vitamin D intake and respiratory tract infections (cold, bronchitis, pneumonia). Taking up to 4000 IU of vitamin D a day may reduce the risk of becoming ill.

Did you know that: In 1849 Vitamin D was used (unknowingly) to treat tuberculosis before the advent of effective antibiotics.

 

#2 – Joint, bone and back pain

Vitamin D is essential to the health of our bones, as it promotes calcium absorption in our body. That’s why joint, bone and back pain might show vitamin D deficiency (low back pain, in particular).

 

#3 – Digestive disorders

Low levels of vitamin D may show up with stomachache, stomach bloating, diarrhea and/or constipation. A few studies have proved vitamin D deficiency may cause intestinal inflammation and even colon cancer.

 

#4 – Fatigue and weakness

We may feel tired for a lot of different reasons, and vitamin D deficiency is one of these reasons. Low levels of vitamin D in our bloodstream may cause fatigue and affect our life quality negatively. Even a slight vitamin D deficiency may affect our energy level.

#5 – Hair loss

Stress is often thought to cause hair loss, yet recent research has shown vitamin D deficiency may cause hair loss too, especially in women.

Low levels of vitamin D are a risk factor for alopecia areata, also known as spot baldness –   an autoimmune condition in which hair is lost from some or all areas of the body.

 

#6 – Mood shifts and depression

Vitamin D deficiency may cause mood shifts and the onset of depression, especially in elderly people.

Taking a vitamin D supplement may boost your mood, memory, concentration and may prove helpful to those who suffer from “winter depression”.

 

#7 – Slow wound healing

A long recovery after surgery or trauma may show vitamin D deficiency.

This vitamin boosts cell regeneration and proves essential when it comes to wound healing, also because of its key role in controlling inflammation and battling infection.

 

#8 – Excessive perspiration

Another function of vitamin D is to control body temperature, as it helps to balance mineral concentration in our body. This vitamin deficiency may cause excessive perspiration, especially on the head.

 

 #9 – Muscle pain

It is often hard to establish the cause of muscle pain. A few studies have shown vitamin D deficiency in children and adults may cause muscle pain.

A Vitamin D receptor is present in nerve cells that are sensitive to pain and are called nociceptors. Vitamin D deficiency may trigger pain when these cells get stimulated.

Vitamin D supplementation in children who suffer from growth pain may help to soothe the symptoms.

 

#10 – Bone mass loss

Low bone density is a proof of calcium and other mineral loss and is then a key factor for bone fractures, especially in elderly people and menopausal women.

People who have been diagnosed with bone mass loss think they need to take calcium supplements, though it might be a vitamin D deficiency, which has a key role in calcium absorption and bone metabolism.

#11 – Hypertension

Research has shown the link between blood pressure levels and vitamin D levels in the bloodstream. The lower vitamin D levels, the higher the blood pressure. Vitamin D supplementation may actually help to battle high blood pressure.

 

#12 – Allergic reactions

A Vitamin D deficiency may increase sensitivity to a few allergens, especially dust mite. Vitamin D supplementation may soothe urticaria and the symptoms of atopic dermatitis.

Proper vitamin D levels protect children from food allergy or asthma.

 

#13 – Weight gain

Vitamin D deficiency may cause the satiety hormone to malfunction, and thus it may lead to excessive hunger and weight gain.

 

#14 – Gingivitis

This is another case of the role of vitamin D in helping our body to battle bacteria. Particularly, this vitamin promotes the production of cathelicidin and defensins – substances protecting oral cavity from infection. Vitamin D deficiency may make gums weaker and inflamed and even cause bleeding.

What are the sources of Vitamin D?

best sources of vitamin d

 

The main vitamin D source is the sun. This vitamin gets synthesized in the skin with the exposure to UV rays. During the winter months UV rays are weaker and it is then more difficult to load up on vitamin D, which may be supplemented through nutrition or food supplementation.

The best food sources of vitamin D are:

cod liver oil, fatty fish (salmon, herring), eggs, butter, liver, red meat, green vegetables.

Nevertheless, it is very difficult to meet the requirements and prevent the deficiency of this vitamin through nutrition alone and, above all during the winter months, it is advisable to take food supplements.

In this case, the most bioavailable form is a vitamin D3 supplement.

 

Overdose and side effects

Clearly, as with all fat-soluble vitamins, also when taking a vitamin D supplement, you must be careful and remember that the recommended dose must not be exceeded.

Here are some of vitamin D intoxication symptoms:

  • nausea;
  • vomiting;
  • fatigue;
  • cardiac arrhythmia;
  • kidney stones (if taken with calcium supplements);
  • confusion and apathy;
  • appetite loss and weight loss;
  • costiveness.
