Tested Vitamin D by Tested Nutrition presents itself in the form of vitamin D3 to support a better quality of life. Vitamin D3 acquires a hormone important function when the cholecalciferol (Vitamin D3) is converted into 1.25-dihydroxy Vitamin D3 (calcitriol) by the liver and kidneys. As a hormone, Calcitriol controls the absorption of phosphorus, calcium, bone metabolism and neuromuscular function. Vitamin D deficiency in the body has been linked to bone and joint problems, kidney problems, impaired respiratory function, and tooth decay.
The lack of vitamin D may also increase susceptibility to several chronic diseases, such as cancer. The ideal level of vitamin D protects both the immune system and the thyroid function, and supports a better sports performance throughout the year.
Vitamin D is produced naturally by the body when exposed to direct sunlight. However, UV exposure and the synthesis of vitamin D are dependent on many factors (seasons, time, location, age, atmospheric pollution, the darkness of the skin, etc)
There is evidence that people with vitamin D deficiency are at increased risk of developing health problems like psoriasis, obesity, osteoporosis, kidney stones, high blood pressure and chronic fatigue. It is therefore necessary to ensure that maintains optimal levels of vitamin D in the body.
