Vitamin D3 in liquid, made by the Thorn company, American supplementation experts, is a perfect way to complement deficiencies of vitamin D3 in diet. Each drop of the product provides 500 mass units of cholecalciferol (vitamin D3).
Vitamin D3 is a supplement which, according to many scientific studies, is used as a basis for supplementation in all people, regardless from their activity, as the amounts of vitamin provided with food are insufficient.
As it is commonly well-known, vitamin D3 can be synthesized in human skin from cholesterol under the influence of sunlight. However, in the period from September to May, the sun angle is unfavourable, which makes it impossible to fully cover the demand for vitamin D3 in this way. Providing it with food (mainly from fishes, eggs and dairy products) is also very ineffective. This is why the supplements with vitamin D3 are gaining popularity.
The symptoms of vitamin D3 deficiency are problems with skeletal system (rickets, osteoporosis) and muscular system (pain and pathological weakening of muscles). Vitamin D3 deficiencies lead also to the increased vulnerability to tooth decay.
Supplementation with vitamin D3 not only protects us from the negative effects of its deficiencies, but also brings many benefits for health and body shape. Numerous studies demonstrate that vitamin D3 increases cognitive skills, positively affects general well-being as well as reduces the risk of diebetes, sclerosis, cardiovascular diseases and cancers.
We should remember that vitamin D3 is a prohormone which is a precursor to 1, 25-dihydroxycholecalciferol, which controls the calcium/phosphate balance of the body system and affects the secretion of parathormone. In case of hormonal regulation, the studies demonstrate a correlation between vitamin D3 and increased insulin sensitivity (and also the secretion of its hormone) as well as increased synthesis of testosterone.
Vitamin D3 shows a beneficial influence on lipid profile as it reduces the level of “bad” LDL cholesterol and the total cholesterol level. The research demonstrated also a decline in the level of triglycerides in blood, which resulted from the supplementation with vitamin D3.
Vitamin D3 has an important influence on the nervous system. Too low concentration of its metabolites in blood is associated with depression, chronic fatigue, weakening of the body system, irritation and lack of motivation. The researchers indicate also a beneficial influence of vitamin D3 on sleep quality.
Vitamin D3 has a wide and multidirectional impact on our health, and its supplementation can help us to fully benefit from its potential. The product offered by the Thorn company is a great solution because of its high purity and its form which allows for convenient and precise dosing. Its great advantage are other components contained in the liquid which maximise the availability of the vitamin.
Vitamin D belongs to fat soluble vitamins, occurs in three forms: calciferol (vitamin D1) ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3), it is formed under the action of sunlight for at least 15 minutes per day. In the absence of sunlight it should be administered in the diet in the form of fish oil (Vitamin A + D3) and fish oils. It is responsible for the absorption of calcium and phosphorus. It is the building substance of bone tissue particularly necessary during pregnancy, childhood, and for athletes. It is a component of dietary supplements and nutrients among competetive athletes. Deficiency of vitamin D causes children growth inhibition, and rickets.
For adults - deficiency causes osteomalacia.
Excess of vitamin D causes headaches, alopecia, nausea, drowsiness, blurred vision, pain in the long bones, the deposition of calcium deposits.
