The everyday use of the preparation is recommended in order to prevent osteoporosis, particularly in the case of seniors as well as menopausal women. Vitamin K and vitamin D work in synergy and significantly help to improve bone structure. Vitamin D also proves excellent as a way to increase the growth of muscle tissue, particularly when used along with leucine. It has been proven that vitamin D and leucine used at the same time help to increase insulin levels and its receptors, thanks to which they are believed to have anabolic properties, particularly desired by those who care about the growth of muscle tissue.
What is Vitamin K2?
Vitamin K2 belongs to fat-soluble vitamins It is an important activator of many enzymes and proteins It shows a positive action on calcium balance by activating MGP protein and osteocalcin. This results in the removal of calcium deposits from blood vessel walls and transport of ions of this element to the area where it fulfills its function – teeth and bones. It reduces therefore the calcification of blood vessels and thus the risk of cardiovascular diseases. Moreover, it is a constituent of coagulation factors and cosequently prevents haemorrhages. It shows a synergistic action in combination with vitamin D and magnesium.
Vitamin K2 in the form of a dietary supplement of renowned brands e.g. Now Foods, Swanson, Life Extension, Jarrow Formulas and Thorne Research) can be found in formulas available at www.muscle-zone.pl
What is menaquinone?
Menaquinone is the term used for vitamin K2. It appears in short- and long-chain forms, the most popular of which are MK-4 and MK-7, containing respectively 4 and 7 isoprene residues in the side chains.
Vitamin K2 exhibits the widest spectrum of its activity by means of osteocalcin, which it has the ability to activate. By means of this hormone produced by bone cells, it may support the state of mineral density of bones and the condition of blood vessels and lower the risk of circulatory diseases. An interesting property of this vitamin is stimulation of Leydig cells to synthesize testosterone, which will be of interest especially to men. K2 also has neuroprotective properties, protecting from excitotoxicity caused by glutamate and oxidative stress from glutathione deficiency. Osteocalcin may also increase adiponectin release from fatty cells, thanks to which it is possible to achieve better insulin sensitivity and decrease inflammations.
Menaquinone is contained in dietary supplements available in the offer of muscle-zone.pl.
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.

Deficiency of vitamin D causes children growth inhibition, and rickets.
For adults - deficiency causes osteomalacia.
