Effects
Effects
Calcium
Calcium exists in greater quantities than any other mineral in the human body. 99% of bodily calcium is located in the bones and teeth, where it provides structural stability and strength. Additionally, calcium plays a role in various cellular processes, including energy production, blood clotting, signal transmission between nerve cells, and the excitation of muscles and nerves.
According to the European Food Safety Authority (EFSA):
Calcium contributes to:
- normal blood clotting,
- normal energy metabolism,
- normal muscle function,
- normal signal transmission between nerve cells,
- normal function of digestive enzymes,
- cell division and specialisation
Calcium is needed for the maintenance of normal bones.
Calcium is needed for the maintenance of normal teeth.
Dosage
Dosage
Directions
Take 2 capsules daily with 200ml water with a meal.
Daily Requirements
The German Nutrition Society (DGE) recommends a daily intake of 1000mg calcium for adults (aged 20 and over). These intake recommendations are aimed at healthy people of normal weight; they do not refer to those with illness or in recovery. Individual requirements (e.g., due to diet, consumption of stimulants, long-term medication, etc.) may therefore be higher than the DGE's recommended intake.
The NRV (Nutrient Reference Value) set by the European Food Safety Authority (EFSA), which determines the amount that an average person should consume daily to cover their needs, is 800mg.
Food Supplement
Do not exceed the recommended daily intake. Food supplements are not a substitute for a balanced, varied diet and healthy lifestyle.
Storage
Keep out of reach of young children. Store in a cool, dry place away from direct sunlight and heat.
