Carefully balanced nutrient combination for bones*
Ostavit takes into account the various nutrients the body uses for optimal bone metabolism*. Calcium is generally known as the key element for maintaining bone structure*. However, besides this essential mineral, the body requires many additional nutrients for the skeleton. That is why we have combined the most important vitamins and minerals in this formula.
Partners in bone health: calcium and vitamin D
Calcium accounts for nearly two percent of total body weight, mainly because it is primarily stored in our relatively heavy bones (99 percent). Here, calcium plays an important role in bone formation and contributes to bone composition*.
Improved calcium absorption through vitamin D3*
This versatile mineral also supports normal muscle function*. Unfortunately, calcium alone is poorly absorbed by the body. That is why Ostavit combines calcium with vitamin D3. The sunshine vitamin helps the body absorb calcium more efficiently*.
Best absorbable forms: D3 and K2 MK-7
However, increased calcium absorption may become problematic when high doses of vitamin D supplementation (from 75 mcg and higher) are required to achieve certain health effects*. Vitamin D increases calcium absorption but does not regulate where this extra calcium is deposited. This can lead to unwanted calcium accumulation in kidneys and blood vessels.
Vitamin K2 supports the maintenance of strong bones*
This is where vitamin K2 comes into play. This calcium distributor helps ensure that absorbed calcium is directed to functional locations such as bones and teeth. As with all our supplements, we use the most bioavailable forms, which is why this product includes vitamin K2.
