Trio of vital nutrients for strong bones

The human body is made up of two percent calcium – for a 165 lb person, this corresponds to around 3.3 lb. This makes calcium the mineral that is most strongly represented in the body. The mineral is particularly necessary for forming bones and teeth. Humans absorb calcium through food. This is best achieved by eating dairy products such as yogurt and cheese, and certain vegetables such as broccoli, kale and rocket.2

Menopausalwomen in particular should keep an eye on their calcium requirements, as the hormonal changes accelerate the decalcification process of the bones. The requirement may also increase during pregnancy and breastfeeding. In addition, increased consumption of coffee or alcohol can increase the likelihood of a calcium deficiency. People who eat a vegan diet or are lactose intolerant should also pay special attention to their calcium intake. All these groups of people can benefit from nutritional supplements containing calcium and vitamins D3 and K2.

Studies show that vitamins D3 and K2 play a crucial role in calcium metabolism, as they enable the mineral to be deposited in the bone substance in the first place.3,4

Vitamin D3 also improves calcium absorption. This means that if calcium is absorbed through the diet or a nutritional supplement, vitamin D3 will help a higher proportion of it reaching the bones. This not only has a positive effect on bone density, but at the same time prevents the mineral from circulating in the bloodstream unused, which may increase the likelihood of vascular deposits.

Recommended dosage

For more than just strong bones

Calcium is essential for the formation and growth of teeth and bones. However, the mineral is also required in the blood plasma, for example as part of blood clotting processes or to stabilize cell walls. In addition, calcium is important for healthy muscle function, because it is actively involved in the transmission of stimuli within the cells.

Excellent bioavailability

Special transport proteins are needed to enable calcium to be absorbed into the bone substance. These, in turn, can only be formed with the help of vitamins D3 and K2.
