Dietary supplements should not replace a varied diet.

What is Bio-Calcium+D3+K

Bio-Calcium+D3+K contains important nutrients for the bones. The combination of calcium, vitamin D3 and vitamin K helps the maintenance of normal bones. The calcium is ionized in the stomach, and the calcium ions are absorbed in the intestine with help from the vitamin D3. Vitamin K is absorbed in the small intestine where it helps maintaining healthy bone and is also part of the ability of the blood to coagulate. Bio-Calcium+D3+K is also suitable as a chewable tablet.

What is calcium?

Calcium is an element and also the most abundant mineral in the human body. The most prominent function of calcium is its need in the maintenance of normal teeth and bones. Bone tissue also functions as the body's calcium storage facility. If the body gets too little calcium, it breaks down calcium from bone tissue to cover its needs.

The percent of the body's calcium which is not channeled into teeth and bones supports different body functions. For instance, calcium contributes to:

  • Normal maintenance of muscle function 
  • Normal neurotransmission
  • Normal blood clotting
  • Normal energy metabolism
  • Normal function of digestive enzymes

Calcium and bones

The bones consist of living tissue that is constantly being replaced. The bone-forming cells are called osteoblasts and the bone-degrading cells are called osteoclasts. As bone tissue also functions as the body's calcium storage facility, it is particularly important that we absorb sufficient calcium in the bones. If the body gets too little calcium, the osteoclasts are activated, which breaks down bone tissue to cover the body's need for calcium.

Children increase their bone mass because the osteoblasts are more active than osteoclasts up to the point where the bones reach their maximum mass, which is usually around 35 years. After that the degradation of bone tissue exceed the amount being build-up. For men, this represents a net loss of bone mass about 0.5% per year and for women around 1% per year.

An active lifestyle also helps to prevent bone loss.

As shown in the following illustration, women are more exposed to bone tissue loss than men. Research shows that women who are treated with estrogen are not necessarily in less need of calcium.

Graph showing that women from 30 years of age loses more calcium from the bones than men.

Where do we get calcium?

  • dairy products       
  • grain and seeds         
  • almonds nuts                       
  • vegetables                 
  • fruit

What is vitamin D?

Vitamin D is a fat-soluble vitamin that is available in several forms, of which D2 and D3 are the most important. D3 is the form of vitamin D that is absorbed most easily in the body. Vitamin D is in fact a pro-vitamin, as we are able to synthesize it in our skin when we get exposed to sufficient amounts of sunshine. Vitamin D is necessary for the body to metabolize calcium and for the function of bones and muscles.

Vitamin D:

Two generations of women

  • Has a role in the process of cell division and specialization
  • Contributes to the maintenance of normal bones,teeth and muscle function
  • Plays a role in the absorption and utilization of calcium and phosphorus
  • Contributes to normal blood calcium levels
  • Supports a normal and well-functioning immune system

In recent years, scientists have focused on our need for vitamin D. Health authorities recommend Vitamin D supplements to children, pregnant women, dark-skinned children/adults, veiled women (and others who wear garments that cover most of the body), and to individuals who rarely or never get exposed to sunlight. In addition, nursing home residents and people over the age of 70 are advised to take vitamin D as a means of protection against brittle bones.

Calcium with vitamin D is necessary for normal bone formation in children.

What is vitamin K?

K-vitamin is a fat-soluble vitamin that supports the ability for blood to coagulate. It is also important for the maintenance of normal bone tissue, as K-vitamin contributes the maintenance of normal bones, through supporting the production of a protein called osteocalcin.

Vitamin K is found in two natural forms: K1 (phylloquinone) and K2 (menaquinone), and a variety of synthetic forms, wherein the water-soluble form called K3 (menadione) is the best known.

A natural source of vitamin K1 are dark green vegetables. Vitamin K2 is produced by our intestinal bacteria. These bacteria can also transform K1 to different variants of K2. Infants can not form vitamin K. We usually get equal amounts of K1 and K2.

K-vitamin and medicine

People who receive blood-thinning medication should realize that an increased intake of vitamin K may reduce the effect of their medicine. However, the vitamin K doses that are known to neutralize the effect of blood-thinning drugs are 70-285 times higher than what is supplied from one Bio-Calcium+D3+K tablet.
