Jarrow Formulas Vitamin D3 is a dietary supplement that includes vitamin D in the form of cholecalciferol. Each capsule contains as much as 2,500 IU of vitamin D3, which is the optimal dose, effectively protecting the body against deficiencies.
The preparation is recommended for the prevention of vitamin D3 deficiencies. They especially affect residents of regions with little sunlight (UVB rays are necessary for the natural production of vitamin D3 in the body), the elderly and obese people. Supplementation is also recommended for people complaining of weak bones and immunity problems.
Vitamin D is a term used to refer to a group of chemical compounds with similar structure and biological activity. Due to its functions, it is often referred to as a prohormone. The human body has the ability to synthesize vitamin D, but UVB rays are required for this process. In supplementation, the most common form of vitamin D is cholecalciferol, or so-called vitamin D3. It is fat-soluble and has the ability to accumulate in the body. In the body, it has a pleiotropic effect.
Action within the skeletal system
The most well-known function performed by vitamin D3 is the regulation of calcium and phosphate metabolism. It is essential for the proper absorption of calcium. It affects osteocalcin, the basic protein of bone, and calbindin, which is responsible for binding calcium. Thus, vitamin D3 contributes to maintaining proper mineralization of bones, ensuring their health, adequate flexibility and strength. Too low levels of vitamin D3 often accompany osteomalacia. This is a dangerous disease that causes weakening and demineralization of bones and degradation of muscle tissue.
Immunomodulating properties
Vitamin D3 modulates the work of the immune system. It inhibits its excessive activity, which is important for protection against autoimmune diseases. In addition, it suppresses chronic inflammation by lowering the level of pro-inflammatory cytokines and raising the level of anti-inflammatory cytokines.
Vitamin D3 contributes to the activation of T lymphocytes, which play a key role in the immune system. It also promotes the synthesis of cathelicidin, a peptide found in the human body that acts as a natural antibiotic.
Neuroprotective properties
Vitamin D3 contributes to increasing intracellular glutathione levels, thus protecting nerve cells from the neurotoxic effects of oxidation reactions. It also delays the unfavorable changes in the density of neurons within the hippocampus that progress with age, which increase the risk of dementia and memory problems.
Scientists have proven that high levels of vitamin D3 protect brain cells from death in the event of a stroke, thus dramatically reducing its negative consequences.
Benefits for athletes
Vitamin D3 may have some benefits for physically active people - supplementing deficiencies increases muscle strength. In numerous tests, it has been proven that workouts performed by people with normal vitamin D3 levels are much more effective than those with hypovitaminosis. Some studies suggest that testosterone levels are raised due to Vitamin D3, mainly by reducing the level of globulin responsible for binding sex hormones.
In conclusion, Vitamin D3 is the best way to deal with vitamin D3 deficiency. The product is recommended especially for sun avoiders, in whom the natural synthesis of vitamin D3 is inhibited. Properly selected dose and form of the vitamin guarantees excellent bioavailability and highest effectiveness.
