Vitamin D – Benefits, Deficiency Symptoms And Diet

Vitamin D deficiency is incredibly common and most people are unaware of it.

That’s because the symptoms are often subtle and non-specific, meaning that it’s hard to know if they’re caused by low vitamin D levels or something else.

What is Vitamin D ?

Vitamin D is a nutrient needed for health and to maintain strong bones. Vitamin D aids in the absorption of calcium and phosphorus in our bodies, helps bring calcium and phosphorus to our bones and teeth, and helps regulate how much calcium remains in our blood. Together with calcium, vitamin D helps protect against the loss of bone mass.

Vitamin D’s importance does not end there. It is also helps muscles function and allows the brain and body to communicate through nerves. And the immune system needs vitamin D to fight off invading bacteria and viruses. There three ways to get vitamin D: the sun, your diet or supplements.

Vitamin D from the Sun

Known as the “sunshine vitamin,” your body converts sunlight into vitamin D after it hits unprotected skin. However, be careful to avoid extended exposure to sunlight without sunscreen.

Benefits Of Vitamin D

1# Helps maintain bone mineralisation

Vitamin D helps to maintain bone mineralisation by ensuring there is a plentiful supply of calcium in the blood stream. This is achieved since vitamin D helps to enhance the absorption of dietary calcium from the large and small intestines. Studies have also linked vitamin D with a positive effect on the deposition of calcium in bone.

2# Prevents ‘diseases’ such as rickets

Since vitamin D helps to maintain bone mineralisation, it can prevent young children and adults alike from developing a ‘disease’ known as rickets. Infants and children who are deprived of vitamin D can develop rickets – meaning they have deformed bones which are unable to support their weight. It also helps to prevent, and treat weak bones (osteoporosis) and bone pain (osteomalacia).

3# Can treat heart/blood conditions

Vitamin D can be used to improve the conditions of the heart, blood and blood vessels. It has been used to treat high blood pressure and high cholesterol (LDL) levels. It has also been used for diabetes, obesity, muscle weakness, asthma, and bronchitis as well as tooth and gum disease.

4# Boosts the immune system

Since vitamin D has a positive effect on your vital organs, such as the heart, liver, lungs and kidneys, it helps to boost the immune system and prevent autoimmune diseases. It has also been linked to preventing cancer.

5# Reduces risk of flu (common cold)

Studies have shown that children who were given 1,200 IU of vitamin D per day for 4 months during the winter has a reduced risk of an influenza infection by 40%.

Symptoms of Vitamin D Deficiency

There are several signs and symptoms of vitamin D deficiency which you should look out for. Just because you have some of these symptoms, it does not necessarily mean you are deficient. However, it is always best to consult your doctor to be on the safe side!

Here are signs and symptoms of vitamin D deficiency.

1# Bone and Back Pain

Vitamin D is involved in maintaining bone health through a number of mechanisms. For one, it improves your body’s absorption of calcium. Bone pain and lower back pain may be signs of inadequate vitamin D levels in the blood. Large observational studies have found a relationship between a deficiency and chronic lower back pain.

One study examined the association between vitamin D levels and back pain in more than 9,000 older women. The researchers found that those with a deficiency were more likely to have back pain, including severe back pain that limited their daily activities. In one controlled study, people with vitamin D deficiency were nearly twice as likely to experience bone pain in their legs, ribs or joints compared to those with blood levels in the normal range.

2# Your forehead is often sweaty

Sweatiness on the forehead is one of the first classic noticeable signs of vitamin D deficiency. If you look like you’re glowing even when your body temperature and activity levels are normal, you may need more vitamin D. Try eating more of these vitamin D-rich foods.

3# You’re prone to stress fractures

Most people think of a lack of calcium when talking about bone health, which is true. However, without vitamin D, calcium doesn’t get absorbed properly, Vitamin D, specifically D3, which increases calcium absorption, is critical to preventing bones from becoming thin and brittle A study found, that people who participate in higher-impact activities may need greater levels of vitamin D to reduce their risk of stress fractures.

4# You can’t get a good night’s sleep

Researchers found that people who took more vitamin D had a 16 percent lower risk of having trouble getting a full night’s sleep, according to a Research. Another large study looked at 1,500 neurological patients over a two-year period who also had abnormal sleep. The sleep improvement with [vitamin D] supplementation was measurable.

5# You’re tired all the time

If you aren’t getting enough vitamin D, you may feel completely exhausted, even if you get plenty of sleep. There is mounting evidence that vitamin D deficiencies are associated with fatigue and sleep disorders. A study found that low vitamin D levels were prevalent in people who are fatigued. Taking more vitamin D helped improve their symptoms.

6# You are obese or overweight

Since vitamin D is fat soluble, body fat can ‘collect it’. The more body fat you have, the more vitamin D is absorbed, meaning less can be properly utilised. The same can be said for people with large amounts of muscle mass, or those with a larger frame. The larger you are, the more vitamin D you require.

7# Weakness

When the body is not able to absorb the calcium due to lack of vitamin D, this leaves you exhausted and weak. Having an adequate amount of vitamin D in the body is essential to provide you the needed energy to go ahead with the day’s work.

8# Severe Hair Loss

Stress can cause loss of hair. But in addition to this your diet also plays a significant role when it comes to hair loss. Lack of certain nutrients in the body, with vitamin D being the major one, leads to significant hair loss among women.

9# You’re 50 or Older

As mentioned, as you get older your skin doesn’t make as much vitamin D in response to sun exposure. At the same time, your kidneys become less efficient at converting vitamin D into the form used by your body and older adults tend to spend more time indoors (i.e. getting even less sun exposure and therefore vitamin D).

It has been proved that with the progression of age, our body has a decreased ability to synthesize vitamin D from the exposure to the sun. Thus, older people are more likely to suffer from this deficiency.

10# Pregnancy And Breast Feeding

Pregnant or breast-feeding mothers require more vitamin D than others. Moreover, there is a greater likelihood of vitamin D deficiency in women who have had several babies with short gaps between pregnancies. This is because the body’s store of vitamin D gets used up during pregnancy and it requires time to be built up before another pregnancy.

Dosages

It is important to know the dosage of vitamin D though, before you go about adjusting your intake.

  • Infants 0-12 months – 400 IU (10 mcg)
  • Children 1-18 years – 600 IU (15 mcg)
  • Adults to age 70 – 600 IU (15 mcg)
  • Adults over 70 – 800 IU (20 mcg)
  • Pregnant or lactating women – 600 IU (15 mcg).

As previously mentioned, sunlight is the biggest sources of vitamin D. However, the best source of vitamin D naturally is from food also.

These foods do contain moderate amounts of vitamin D, however if you are deficient, then the most convenient, cheapest way is to invest in a supplement.

There are a few different kinds of supplements available. One is vitamin tablets, such as Vitamin D3. These are a great direct source of vitamin D, and are easy to consume, so you can instantly hit your daily goals!

Finally, you can opt to take a multivitamin. but consultant your doctor before take.
