Kal D3 - 30 tablets

Calcium is the most abundant mineral in the human body: it accounts for 1 to 2% of body weight (1 to 1.5 kg) and 99% is found in bones and teeth
In addition to its obvious role in the structure and strength of these tissues, calcium also participates in muscle contraction, nerve cell activity, and blood clotting
Despite its strength and rigidity, bone tissue is not static but rather a dynamic structure: old bone tissue is constantly being replaced by new bone. This is achieved through the active breakdown of bone the release of calcium into the circulation, and its reabsorption into the newly formed bone matrix
Several factors can negatively affect circulating calcium levels: unbalanced diet, age, lactation, menopause, and the use of glucocorticoids and laxatives. A small portion of calcium is also naturally excreted in the urine. To compensate for low blood calcium levels, bone is broken down to release calcium. This is why a consistent supply of calcium through the diet is essential.
Not only is the total amount of calcium consumed important for maintaining strong bones, muscles, and nerves: From food to bones, calcium follows a complex pathway. Without the help of two vitamins, this would not be possible
From food to blood: Dietary calcium is absorbed in the intestine by a specific transporter stimulated by vitamin D3. This vitamin is also responsible for the calcium and phosphate balance in the blood, which is essential for bone formation
From blood to bones: Circulating calcium is transported to the bone matrix by proteins such as osteocalcin. This is only possible if osteocalcin is activated through a vitamin K-dependent reaction.
The right combination!
The calcium, vitamin D3, and vitamin K in Doppelherz® aktiv KalD3 tablets form the ideal combination for reaching the recommended daily calcium intake and ensuring optimal calcium integration into the bones
