Your body is your most priceless possession... so take care of it.
The optimal level of vitamin D in the blood is considered to be higher than 75 nmol/l. If vitamin D is below normal in the blood test, then we recommend an injection of 200 000 IU, and an injection of 100 000 IU every few months is enough to maintain its optimal level.
Overdose of vitamin D in the sun is not possible because the body regulates its production, but care must be taken not to get sunstroke or burn on the body. The supply of vitamin D obtained on sunny summer days is depleted within two months, just in time for the onset of the disease season, which is when Vitamin D is most needed by our immune system for normal functioning.
Vitamin D performs a number of important functions in our body, such as regulating calcium levels. The base level of calcium absorption is only about 10-15%. Vitamin D increases the absorption of calcium by almost 80%, thus strengthening our bones. Older people naturally produce nearly 75% less vitamin D than younger people.
Enough vitamin D in the body also helps prevent certain forms of cancer, since this vitamin is involved in regulating the immune system and reduces the production of inflammatory cytokines in the body. Cytokines - produced by immune cells in the area of infection and are very dangerous when their blood levels are too high, they can provoke an increased inflammatory response and disrupt a number of bodily functions.
Research published at Boston University suggests the dangerous effect of vitamin D deficiency when vitamin D levels are below normal (75 nmol/l) is associated with an increased risk of schizophrenia, depression, cancer and autoimmune disease.
An undesirably high level of vitamin D in the blood is considered to be from 250 nmol/l, and toxic from 375 nmol/l.
Vitamin D helps prevent weight gain, for example, it can reduce the formation of new fat cells. Vitamin D has been found to help control appetite that reduces overall calorie intake. In addition, vitamin D increases testosterone levels in men, which speeds up the metabolism and helps with weight loss.
Vitamin D deficiency is associated with both headaches and migraines, and levels below 75 nmol/l can cause fibromyalgia, back pain, arthritis, and other health problems.
Low vitamin D levels can decrease sexual desire in both women and men. Erectile dysfunction is more common in men with vitamin D deficiency, sufficient vitamin D intake increases sperm motility and regulates the production of sex hormones. With higher vitamin D levels, IVF (in vitro fertilization) success rates are better.
Vitamin D plays a key role in maintaining brain serotonin levels, and increasing blood levels of vitamin D (for example, after an injection) reduces both anxiety and depression.
By regulating the action of a protein that kills pathogens (cathelicidin), vitamin D strengthens the immune system and helps prevent bacterial and viral infections.
Vitamin D stimulates the production of osteocalcin (a non-collagenous protein in bone), which regulates bone growth. Vitamin D deficiency depletes minerals (calcium and phosphorus) from bones, making them more brittle.
Lack of energy or fatigue is usually associated with vitamin D deficiency. It helps the mitochondria (energy-producing cell) use oxygen and provide energy to various parts of the body.
