Vitamin D-3 & K-2 Vitamin D-3 & K-2

Now Foods Vitamin D3 & K2 is a dietary supplement that contains three synergistic vitamins in one capsule: vitamin C, D3 and K2. The correct proportion of ingredients provides a safe and effective action.

Vitamin C (ascorbic acid) is a chemical compound, belonging to the group of unsaturated polyhydroxy alcohols. It's necessary for the functioning of living organisms. It must be supplied in the diet because our body cannot synthesise or store this element. It has many health benefits. It helps to reduce a feeling of fatigue. It supports the proper functioning of the immune and nervous system and helps protect cells from oxidative stress.

In addition, ascorbic acid contributes to the healthy synthesis of collagen which is aimed at the normal function of the teeth, gums, skin, bones, cartilages and blood vessels. It also contributes positively to the maintenance of proper energy metabolism and psychological functions. It has an impact on the muscular system by lowering cortisol levels in the body.

Vitamin D3 (cholecalciferol) is an organic chemical compound, steroid-like and fat-soluble. It's found naturally in animals. In the human body, it acts as a prohormone. It works with vitamin K2, vitamin A and calcium. It's called often the sunshine vitamin because it's synthesised in the skin by the conversion of cholesterol under the action of UVB light (the exposure to sun must last at least 15 minutes).

As a result of photosynthesis, lumisterol is formed which consequently undergoes the thermal conversion in animal organisms to cholecalciferol. When sunlight is weak, the vitamin should be included in the diet. It promotes the proper absorption of calcium in the body and its transport to bones. It's beneficial to the skeletal system. This element also supports the body's immune and nervous system.

Vitamin K2 (menaquinone) is found in animal products and fermented plant foods. It affects many biological functions in the body, primarily calcium balance. Its primary role is the modification of proteins so that they can bind calcium. It also contributes to the maintenance of normal bone health, is responsible for the correct  calcium distribution to bones. It has also a positive effect on the circulatory system, ensuring proper blood clotting. In addition, it also reduces the risk of calcium deposits in the arteries.

Why the combination of D3 with K2?
The blend of vitamin D3 and K3 is not random. Vitamin D3 is responsible for regulating calcium-phosphate balance in the body. This action is complemented by vitamin K2 which directs these  substances to the right areas.  Too much vitamin D3 can lead to calcium deposition in soft tissues, e.g. in the kidneys and arteries, but when it's combined with vitamin K2, it will help avoid these problems.

To sum up, Now Foods Vitamin D3&K2 is a dietary supplement designed mainly for athletes and physically active people. Furthermore, the product is intended for everyone due to insufficient sunlight throughout the year to achieve the optimal level of vitamin D3. The product also provides vitamin K2 which is necessary in this combination.

Vitamin C

Information


Vitamin C (ascorbic acid) it is a vitamin soluble in body fluids, can be taken from foods (fruits and vegetables), or as drug derived synthetically. The largest of its resources can be found in broccoli, Brussels sprout, kale, black currant fruit and hawthorn, citrus fruits, tomatoes, Savoy cabbage, potatoes. In fact, intake of vitamin C of the food products does not limit the absorbed quantity. Vitamin C (ascorbic acid) is a potent antioxidant, it is an antitoxic, increasing the immune system due to the elimination of risk of bacterial contamination. Vitamin C prevents rupture of blood vessels, affects the blood cholesterol level. It substantially increases the absorption of iron. Inhibits the growth of cancer cells. Lowers stress levels.
Vitamin C deficiency causes abnormal development of connective tissue, cracking capillaries, abnormal calcification of bone tissue, impaired
absorption of iron, scorbutus. With the lack of vitamin C, all kinds of injuries do not heal up properly. Vitamin C deficiency can be caused by smoking; each cigarette is destroying up to 100 mg of vitamin C.
Dosage: The demand is 60-80 mg daily. It does not limit the ability to consume higher doses. Some side effects may occur only with longer
taking of synthetic vitamin C.

Vitamin D

Information

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.
Dosage: 400 IU units during the day.


 

Cholecalciferol

Information

Cholecalciferol, or vitamin D3, is an organic chemical that belongs to the family of D vitamins. It is naturally found in fatty fish, fish oil, egg yolks, milk and dairy products. It is also synthesized in the human body. It is formed from 7-dehydrocholesterol present in the keratinocytes of the spinous and the basal layers of the epidermis, and a pre-requisite for initiating this process is the action of 290-315 nm wavelength UVB radiation on the skin.

Cholecalciferol is a biologically inactive compound. In the body, it undergoes enzymatic hydroxylation – first in the liver, with the participation of 25-hydroxylase, when calcidiol is formed and secondly in the kidneys, where under the influence of 1-α-hydroxylase, calcidiol is converted into the final active form – calcitriol.

The most important role of vitamin D3 in the body is the regulation of calcium-phosphate metabolism, which directly affects normal skeletal mineralization. In addition, it is involved in cell proliferation and differentiation, insulin secretion, as well as in some functions of the nervous, endocrine and immune systems.

Cholecalciferol is the most popular form of vitamin D used in dietary supplements. Studies show that supplementation with vitamin D in this form most effectively and rapidly raises the level of 25 (OH) D3 – a metabolite that is a marker of the level of vitamin D in the body.

Dosage: according to RDI standards for individual age groups.

Lanolin

Information

Lanolin is obtained in the process of cleaning of raw sheep wool from the so-called wool fat, protecting it from getting wet and unbeneficial weather conditions.

Lanolin is commonly used for the production of ointments and creams with lubricating and softening effect, however, it also found application in the production of dietary supplements and more precisely vitamin D3.

In order to obtain vitamin D3 from lanolin, it undergoes cleaning and crystallization and then proper chemical processes, as a result of which 7-dehydrocholesterol is produced - a precursor of vitamin D3, the same which is produced in skin under the influence of UV radiation. 7-dehydrorocholesterol obtained from lanolin is then subjected to the above mentioned radiation, being transformed to vitamin D3.

Vitamin K2

Information

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

Menaquinone

Information

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.
