Complex for bones and muscles

KNOCHENSTARK by Naturtreu is an advanced dietary supplement combining calcium and plant vitamin C derived from the finest camu camu fruit.

This complex offers high doses of calcium in the form of calcium carbonate, which is characterized by exceptional bioavailability and rapid absorption in the body. One daily dose, i.e. three capsules, contains 804 mg of calcium.

Calcium, a vital mineral, is almost 100% found in bones and teeth and is needed to maintain normal bones and teeth and contributes to normal muscle function.

KNOCHENSTARK uses plant vitamin C from hand-picked camu camu berries, which contributes to normal collagen production for normal bone function and calcium-related processes.

A few recommendations that can help your bone health

Once the health of your bones starts to deteriorate, there are still effective ways to care for them. One of the best ways to restore bone density is regular exercise.

Activities that use your own weight, such as weightlifting or brisk walking, are particularly beneficial. These forms of exercise stimulate osteoblasts, the cells responsible for bone formation, which can lead to improved bone density over time.

A healthy and balanced diet is key to building strong bones from an early age and maintaining them throughout life. To strengthen bones, it is also advisable to increase calcium and magnesium intake, which promote bone strength and density.

This can be achieved both through diet and by taking supplements containing these minerals.

They are essential for healthy muscles and bones:
