If there is vitamin in the world, which can help optimally promote health and to improve human health, that vitamin D (also known as vitamin D3 or cholecalciferol). Traditionally, vitamin D deficiency associated with bone disease — rickets, as well as the disease is now rare, many believe that vitamin D deficiency is not. This is absolutely not true!

Fortunately, this very essential vitamin can be produced and absorbed by the organism-free when a person spends time in the sun — the sun’s ultraviolet rays B (UV-B) react with a form of cholesterol in our skin and produce the hormone vitamin D. However, for optimal health most people this is not enough. In addition, because many people around the world spend more time indoors than outdoors, to achieve the desired level of vitamin D in the blood from exposure to the sun is difficult, and most people need to Supplement the diet supplements.

Thousands of studies over the last decade demonstrate the health benefits while optimizing the consumption of vitamin D. These studies tell us that people with higher levels of vitamin D in the blood have a lower risk of heart attacks, breast cancer, colon cancer, multiple sclerosis, diabetes 1st and 2nd type, hypertension and other complications.

However, many tend to avoid the sun. A lot of people all over the world, usually on the recommendation of a doctor struggling to limit time spent in direct sunlight. This is done in an attempt to prevent essentially life-threatening basal cell and squamous cell skin cancer. Melanoma, a dangerous form of skin cancer, affects 1 in 80 people. However, half of the cases of skin cancer — melanoma — occurs in closed to the sun parts of the body.

In an attempt to avoid the fate of one of eighty people, who developed melanoma, we actually increase the risk of developing breast cancer (1 of 9), colon cancer (1 in 18) and prostate cancer (1 of 6), limiting the impact on the body sun rays involved in the production of vitamin D.

Who suffer from vitamin D deficiency?

I am a physician in southern California where the Sunny weather over 300 days a year, and four out of five (80%) of my patients had a clinical vitamin D deficiency defined by a blood level of 30 ng/ml (75 nmol/l) or lower.

The reason for this is that few people conduct the required 15-20 minutes every day in the sun, letting your face, hands and feet exposed to ultraviolet light. Vitamin D deficiency is experiencing up to 90% of people around the world. Those who have more melanin is responsible for darker pigmented skin to produce vitamin D is required for up to 30 minutes in the sun. People over 65 years of age to produce vitamin D, too, need to spend more time outdoors due to the fact that the skin with age loses elasticity.

Vitamin D is produced in the skin by exposure to the sun only at certain times of the day. Generally speaking, the production of vitamin D occurs when your shadow “short growth” — usually from 10am to 2pm. Interestingly, at the same time there is a maximum performance of solar panels!

Those who does sunscreen before going outside, blocking the sunlight on the skin and the production of vitamin D. Sunscreen should be applied 15-30 minutes of sun exposure.

What are the risks of low vitamin D levels?
High blood pressure (hypertension)

High blood pressure affects one in four adults. Worldwide hypertension hurt 1 billion people. High blood pressure — a major risk factor for heart attacks, strokes and congestive heart failure. Although there are many causes of hypertension, studies show that men with low vitamin D are six times more likely to develop hypertension, and women almost three times more. Maintaining a healthy weight, diet high in fruits and vegetables and daily exercises also help to control blood pressure.

So what can vitamin D do? Scientific studies show that vitamin D helps to relax the blood vessels that carry blood throughout the body, which leads to a decrease in blood pressure. Vitamin D deficiency also is probably one of the main reasons why people with more intense skin pigmentation are at higher risk of hypertension occurrence.

Heart attacks

Cardiovascular diseases are the leading cause of death in the United States, Europe and Asia. In the United States, heart diseases claim nearly 1 million lives a year. A Harvard University study showed that people with higher vitamin D levels in the blood, the risk of heart attacks was 80% lower than that of people with the lowest levels of vitamin D.

According to a German study, people with lower levels of vitamin D in the blood are five times more likely to die suddenly from a heart attack compared to those with vitamin D levels in blood above. Many other studies have shown similar results.

In 2017 the study concluded: “… vitamin D levels in the blood were significantly lower in patients with cardiovascular disease, especially in America and Asia. Sufficient levels of vitamin D in the blood can protect against the occurrence of heart attacks.”

Breast cancer

Breast cancer sick one out of nine women. Mammography helps detect cancer, but the priority here should be not just early diagnosis but also cancer prevention.

Despite the fact that the prevention of breast cancer promotes healthy eating and maintaining a healthy weight, research shows that vitamin D may also be important. A 2007 study at the University of California San Diego noted a reduction of 50% of breast cancer in women vitamin D levels in the blood which amounted to more than 52 ng/ml (125 nmol/l). According to another study, women who live in areas with more intense sunlight, decrease breast cancer at 25-65%.

Numerous studies have shown benefits of vitamin D in reducing breast cancer. In July 2017 the study, which involved nearly 51,000 women, showed that supplementation with vitamin D reduces the risk of developing breast cancer by 21% in postmenopausal women (who already stopped the monthly menstrual cycle).

Colon cancer and stomach cancer

According to the American cancer society the death rate from colon cancer is 8% of all cancer deaths in men and 9% of all cancer deaths in women. In 2016, the world has registered more than 1.3 million cases of colon cancer. Fortunately, most cases of morbidity can be prevented.

In addition to a healthy diet high in fiber vitamin D may help prevent colon cancer. Scientists have shown that the inhabitants of Sunny regions have lower rates of colon cancer. Two studies published in 2005 and 2007, showed that people with higher levels of vitamin D in the blood, the risk of developing colon cancer could be reduced by 50%. The authors of another study concluded that elevated levels of vitamin D reduces cancer by 60%.

A study in 2014 showed that patients who have been diagnosed with cancer of the colon and a higher level of vitamin D in the blood were less likely to die from the disease than those whose vitamin D levels were lower. Similarly, according to a 2016 research, stomach cancer is almost five times more common in patients with a deficiency of vitamin D.

Other diseases associated with vitamin D deficiency

Numerous other studies show that people with lower vitamin D levels often observed following diseases:

  • dementia
  • strokes
  • of peripheral artery disease
  • prostate cancer
  • ovarian cancer
  • pancreatic cancer
  • fibromyalgia
  • epilepsy
  • fractures
  • multiple sclerosis
  • lupus
  • rheumatoid arthritis
  • asthma
  • autism
  • psoriasis

The importance of vitamin D is obvious, and supplementation is crucial to your health.

How about the toxicity of vitamin D?

There is no such thing as true “vitamin D toxicity”. However, a daily intake of over 10,000 IU of vitamin D over time can lead to the absorption of too much calcium, which causes an increase of calcium in the blood and growth of kidney stones. Patients suffering from chronic kidney disease, lymphoma, or having a high level of calcium in the blood, you should consult with your doctor before taking supplements with vitamin D.

Find out your vitamin D level

Ask the doctor to check the level of vitamin D in your blood. The physician must write a referral for a blood test for vitamin D 25-OH. Most laboratories measure standards — from 30 ng/ml (75 nmol/l), 100 ng/ml (250 mmol/l). The optimal level of vitamin D in the blood should be between 50 ng/ml to 100 ng/ml (125-250 nmol/l).

Taking supplements

Adults with greater vitamin D deficiency you need to take it in the dose of 2000-5000 IU of vitamin D (cholecalciferol). Someone may need and more. Pregnant and lactating women should also consider supplementation with vitamin D at a dosage of 5000 IU per day. Vitamin D can take healthy children aged 1 to 18 years. The usual dose is 1000-2000 IU per day.

Vitamin D supplementation needed by the body all year round. However, intake of vitamin D is particularly helpful in those seasons when there is little sun. Sometimes doctors prescribe vitamin D2 (ergocalciferol) in dosages of 50,000 IU once a week. Based on these studies, vitamin D3 is clinically more effective and preferred Supplement.

You can also increase your vitamin D levels, spending 15 minutes in the sun every day without sunscreen, with open face, arms and legs. Regular exercise in the fresh air is also very healthy.

Prevention of chronic disease is key to longevity and improving quality of life. Inclusion in the daily diet supplementation with only vitamin D can actually help us achieve this goal
