Swanson Vitamin D-3 4000 IU is a unique dietary supplement containing a high dose of cholecalciferol - a form of vitamin D found in animal products. In the body, it is directly converted to 25 - hydroxycholecalciferol in the liver and then in the kidneys to the most potent form - calcitriol.
Until recently, it was claimed that the only action of vitamin D was its regulatory effect on calcium metabolism and bone mineralization. However, the development of medicine has allowed the discovery of quite new and revolutionary functions of this wonderful substance.
Supporting bone mineralization
A function of vitamin D that has been known for years is its positive effect on bone mineralization processes. This action is made possible by three mechanisms. The first is the stimulation of the synthesis of a specific protein that enhances calcium absorption in the small intestine.
Another is to regulate the absorption of phosphorus, which naturally competes with calcium in the body. Calcitriol also enhances the retention of calcium in the body and promotes its incorporation into bone cells. All of this ensures that the bones stay in good shape for years to come and prevents such a serious disease as osteoporosis.
Fighting germs
A relatively recently discovered effect of vitamin D is its stimulating effect on the immune system. Numerous studies confirm that by stimulating the production of specific cytokines, it causes an increased defense response of the body against pathogenic bacterial invasions.
In addition, it has been discovered that it initiates the synthesis of a unique protein with potent bactericidal activity. These mechanisms significantly contribute to strengthening the body in the fight against microorganisms, especially during the autumn and winter.
Regulation of the immune response
In recent years, there has been a significant increase in the incidence of so-called autoimmune diseases. This is a huge group of serious conditions, which include multiple sclerosis, Hashimoto's disease, inflammatory bowel disease or type 1 diabetes, among others.
Studies have confirmed that immune-active cells such as Th and B lymphocytes are equipped with receptors for vitamin D. Thus, it interacts with them directly, inhibiting their excessive pathological activity. It also regulates their effects on the body, which underlies the development of the aforementioned diseases.
Fighting cancer
Another revolutionary discovery in the action of this vitamin was the finding of its protective effect in the development of cancer. Research confirms that it has a huge impact in counteracting the formation of about 17 types of cancer, including breast, uterine, prostate or stomach cancer.
Vitamin D significantly reduces the accumulation of mutations in the human genome, which is the primary factor in tumorigenesis processes. It also has a growth-limiting effect on cancer cells and can limit the formation of metastases.
Healthy circulatory system
Hypertension is one of the most common diseases of the circulatory system, significantly increasing the risk of atherosclerosis and myocardial infarction. Research in recent years confirms that vitamin D has the ability to regulate blood pressure and counteract ischemic heart disease.
Increase muscle strength
A little-known effect of vitamin D is its influence on the proper functioning of skeletal muscles. Even slight deficiencies of this vitamin result in a significant decrease in muscle strength, and proper supplementation helps counteract this phenomenon. In addition, the researchers noted that in people with normal levels of calcitriol, exercise produces much better results.
In conclusion, Swanson Vitamin D-3 4000 IU, is a supplement with a very broad spectrum of action. In addition to protecting the skeletal system, it also supports the body in the fight against microorganisms, cancer and autoimmune diseases. In addition, it also has applications for athletes looking to optimize the results of their training.
