The preparation contains easily assimilable, ionized calcium compounds derived from calf bones. It is worth remembering that calcium is naturally found in the ionic form. Upon entry into the body, it is converted to a molecular form (an insoluble calcium salt). Such a molecule cannot enter the cell, because only for ions can get across the cell membrane. Thus, it is better to use supplements containing ionized calcium, not calcium carbonate (derived from oyster shells, for instance), which is less digestible and may neutralize gastric juices. Vitamins help the body absorb calcium, hence their presence in the preparation. Vitamin D regulates homeostasis of calcium and phosphate in the body, which means the amount of calcium and phosphorus, absorbed in the intestine from food into the bloodstream, depends to a great extent on this vitamin. Vitamin D deficiency reduces calcium absorption, even when the diet is rich in this micro-element. This may finally result in bone demineralization. Additionally, vitamin D regulates the metabolism and the function of the body’s natural defense mechanisms, hence its deficiency increases the risk of infection. In contrast, vitamin K plays an important role in blood clotting and has a significant impact on calcium metabolism and proper bone calcification. An additional ingredient contained in the product – vitamin C – is a powerful antioxidant, protecting against free radicals. In addition, it accelerates lipid metabolism and is essential for collagen synthesis. It also ensures the proper development of cartilage, bones, teeth and keeps the capillary walls in a healthy condition. Another powerful antioxidant is vitamin E. Besides the antioxidant properties, it inhibits oxidation of the so-called bad cholesterol (LDL) preventing atherosclerotic plaque formation. It also prevents clot formation inside blood vessels. This TIENS preparation also contains vitamin A, which is a potent antioxidant neutralizing free radicals responsible for aging. This vitamin stimulates collagen production, which prevents loss of skin firmness, and accelerates the metabolism of the cells. Vitamin A is also known to affect the dark adaptation of our eyes. Its deficiency can cause thickening of the cornea, the transparent front part of the eye. In turn, the B group vitamins, are known to affect the metabolism and proper functioning of the digestive and nervous systems. Moreover, they are essential to maintaining healthy hair, skin, and nails.
The product compounds exhibit a broad spectrum of activity:
calcium, vitamin D and K – help maintain the proper levels of calcium in the body, which strengthens the bones, prevents osteoporosis and positively affects teeth condition,
calcium, vitamin D – have a beneficial effect on the function of muscles,
calcium and vitamin K – ensure proper blood clotting,
calcium relieves the symptoms of allergies,
calcium supports the proper functioning of the nervous system,
vitamins E, A, C – keep the skin, hair, and nails in healthy condition and prevent aging
vitamin D – enhances the body’s natural defense mechanisms.
The preparation should not be used by children under 12 years. In case a doctor prescribes an antibiotic, inform them of taking calcium, as this may decrease antibiotic absorption.
Excess calcium is equally disadvantageous as its deficiency. Calcium supplementation should be consulted with the doctor, as for instance in patients suffering from kidney stones, excessive calcium intake may increase kidney stone formation. Excess calcium may also limit the absorption of other minerals such as zinc, magnesium, iron or fluorine. It is hence recommended to keep a three-hour break between supplements containing these elements.
