Misinformation about nutrition, the importance of a healthy, balanced diet and nutritional supplements is spreading throughout the media and medical institutions, but they are silent about the fact that the consequences of isolation from sunlight are critical vitamin D deficiency in people of all ages.
Prof. Dr. Jörg Spitz, in his presentation: Vitamin D "Hope oder Hype", discusses the importance of vitamin D. He concludes that there is an epidemic of vitamin D deficiency and that there is nothing that public health officials and health agencies are doing to tackle the problem.

Here are some key takeaways:
- Claims that most people lack vitamin D are not true.
- You cannot "stock up" on the vitamin in the winter, spending time in the sun. This will not work because the sun's rays at higher latitudes are at an angle much lower than 45 °, and the required UV radiation does not reach the surface.
- 88% of Germans have vitamin D levels below 30 nanograms per ml, well below the target range of 40-60 ng.
- Only 6% of German women and 1% of German men make up for the lack of vitamin D.
- In recent years, more and more people, including children, are chronically deficient in vitamin D due to poor nutrition and a sedentary lifestyle.
According to the study, only 10% of children have sufficiently high vitamin D levels in late summer, and only 0.9% in winter! "Disaster," says Spitz.
This problem also exists in sunny, tropical latitudes - there people are indoors all day.
- Sunscreen and work clothes block essential UVB rays from the sun.
- 30,000 Swedish women were followed up for 20 years. The mortality rate among women who avoided the sun was twice as high as among those who spent a lot of time in the sun. "Those who spend time in the sun live longer."
Risks
“Lack of sun, Spitz says, is just as dangerous as smoking.
If your vitamin D level is below 20 nanograms / milliliter, your chances of getting chronic diseases increase 2-3 times.
- You cannot get the vitamin D you need through food alone. You must synthesize it using sunlight absorbed by the roughly 2 square meters of skin that you are endowed with. Don't use sunscreen too often.
- Sunscreen lotion even gets absorbed into the body, reacts with sunlight and leads to the formation of other questionable chemicals in the body.
- Obesity leads to a decrease in vitamin D levels, as it is stored in fat.
- Almost every chronic disease is associated with vitamin D, such as dementia, Alzheimer's, depression and other neurological diseases.
- Athletes with vitamin D deficiency have lower athletic performance - a much higher risk of injury.
- Heart attacks, diabetes, metabolic syndrome, etc. are associated with vitamin D deficiency.
- Vitamin D is extremely important for all organs; all organs have vitamin D receptors.
- Vitamin D is a key factor in the fight against cancer and tumors.
- Diabetes during pregnancy, childbirth complications, and developmental problems are associated with low vitamin D levels.
- Natural biological processes cannot be replaced by medical practices!
- Children's health will continue to deteriorate as vitamin D levels decrease.
- Nine lifestyle factors have been identified as major contributors to heart attacks, each of which increases the likelihood of a heart attack by 2.5 times. The presence of four of these factors increases the likelihood 40 times.
- Only 9% of German adults are successful in maintaining a good weight, not smoking, exercising regularly, and eating a balanced diet.
“Health officials have failed in smart prevention.
“The immune system is highly dependent on vitamin D." Consume it or you get sick, "Spitz says.
- Children with normal vitamin D levels are 70% less likely to get colds.
And as a number of experts point out, low vitamin D levels have been linked to severe cases of COVID-19.
How much vitamin D?
Since vitamin D is a pro-hormone produced by our skin when exposed to UV rays, the skin needs sunlight to produce it. Vitamin D is also present in some foods, but its concentration is significantly lower than the amount of vitamin D produced by the skin in the sun
- Vitamin D levels after sun exposure are significantly lower in older people:

- Recommended supplement = 4000 IU / day for adults (70 kg) - try within 3 months.
- Rule: Supplementing 1000 IU per day increases vitamin D levels by about 10 ng (based on a body weight of 70 kg).
- It is very difficult to achieve "too high" levels of vitamin D, so there is no need to worry about it.
- Three ways to increase your vitamin D levels: 1) supplements, 2) tanning beds 2-3 times a week, 3) 30 minutes at noon 3-4 times a week. Choose what suits you best.
Taking vitamin D is one of the easiest and fastest measures you can take to improve your health.
- Ask your doctor to check your vitamin D level and proceed. If at the end of winter your level is above 30, then everything is in order. If it is less than 30, then you can easily restore its level with the help of supplements. If you are under 20, then you have the opportunity to start significantly improving your physical and mental health.
Be sure to check with your doctor who understands the importance of vitamin D

Lecture by prof. Dr. Jörg Spitz
The professor spoke about this problem back in 2018, but now it is most relevant in terms of what is happening and associated with Covid-19: blockages, self-isolation, quarantine, restrictions, and all this limits the time people spend in the Sun in their natural environment. Therefore, it can be assumed that the problem of vitamin D deficiency has now become even more common. As the professor points out in his speech, a lack of vitamin D is fraught with serious danger for people.
Hardly any medical topic is discussed as controversially as vitamin D. For some it is a miracle drug, but for others it is just a business with a toxic substance! For some it is a miracle drug, while for others it is just a profit on a toxic substance! But it has long been clear that vitamin D is not a vitamin at all, but a precursor to the sun hormone, which, like all other hormones, we need for the proper functioning of our body (and mind!). It doesn't matter if it's about sex hormone, thyroid hormone or sun hormone. Due to lifestyle choices in the 21st century, vitamin D has unfortunately been lost to a large portion of the population - with serious health consequences for those affected.
