Vitamin D and its role in the human body is currently an important and widely studied topic in many countries. In Lithuania, a study of vitamin D levels in the blood of young men found that 95% of the subjects were deficient in this trace element. Vitamin D is associated with good bone, dental and muscle health, immunomodulatory and anti-inflammatory effects, as well as an influence on autoimmune processes.
Vitamin D and its role
Compared to other micronutrients needed by our bodies, this vitamin is found only in a narrow range of foods: oily fish, eggs, mushrooms. 90% of vitamin D is produced in the skin by exposure to the sun’s ultraviolet beta (UVB) rays and only about 10% is absorbed from food in the small intestine. However, the amount of vitamin D in the body is determined by individual characteristics, skin pigmentation, place of residence, exposure to the hot sun, food intake, lifestyle and other factors.
It has long been shown that vitamin D deficiency leads to disturbances in calcium and phosphorus metabolism, which in turn lead to the development of bone diseases such as rickets, osteomalacia and osteoporosis. However, new evidence suggests that vitamin D deficiency affects the onset or progression of most diseases. Vitamin D deficiency has been linked to the development of autoimmune, oncological, endocrine, neuro-psychological, cardiovascular, infectious and other diseases.
Signs of vitamin D deficiency:
women with low blood levels of vitamin D deficiency are twice as likely to suffer from depression.
High blood pressure –
Vitamin D is essential for the cardiovascular system. It helps regulate blood pressure, so when it is deficient, blood pressure can become unbalanced.
Increased sensitivity to pain –
vitamin D deficiency can be associated with chronic pain.
Fatigue and drowsiness.
vitamin D has an effect on serotonin produced in the brain. A deficiency of this happiness hormone can contribute to mood swings.
Muscle weakness –
reduced muscle volume or perceived muscle weakness can be a consequence of a vitamin deficiency.
Reduced stamina –
studies suggest that reduced stamina may be related to vitamin D deficiency.
If you are considering a vitamin D supplement, read these facts:
The intensity of the product is determined by the number of International Units (IU) per serving.
Before choosing a product, it would be best to have a bioresonance test to find out if you are deficient in vitamin D.
The most easily absorbed liquid and active form of this supplement is vitamin D3.
If vitamin D levels are within the normal range, it is suggested that adults should take 800-2000 IU and people over 60 should take 2000-4000 IU also check witamina d3 20 000 + k2 if you looking for bigger options.
The orthomolecular daily intake of vitamin D is 5000 IU per day.
About the vitamin and its forms
Vitamin D is a fat-soluble vitamin. Only a small proportion of foods are fortified with this vitamin. The main natural source of vitamin D is production in the skin (exposure to UV radiation signals synthesis).
Vitamin D obtained from food, supplements or sun exposure is not biologically active – further metabolism (hydroxylation) must take place in the liver and kidneys. This produces the fully active forms 1,25-dihydroxyvitamin D2 and 1,25-dihydroxyvitamin D3 (calcitriol), which are involved in further metabolic reactions within the body.
