Calcium Supplementation and Intake – Benefits Beyond Bones
The significance of calcium for life on Earth is undeniable, as this mineral is essential for various biological processes. Many may not realize that calcium’s role extends beyond the health of bones and teeth; it ranges from reproduction to the functioning of nerve and muscle cells, and even to communication between cells. It is crucial for the human body to obtain an adequate amount of calcium, as a deficiency can lead to various health problems.
Calcium intake, determined by our diet, has been decreasing over the years, which is a concerning trend. Due to modern lifestyles and dietary changes, many people do not get enough calcium, thus increasing the necessity for calcium supplementation. Ensuring a healthy calcium intake is key to long-term health maintenance, yet many are unaware of how much calcium they actually need.
Calcium Requirements and Intake
The normal level of calcium in the blood is strictly regulated and ranges between 2.2-2.6 mmol/l. If this value falls below or exceeds the specified limits, it can cause serious health issues. The body can maintain calcium levels, but it requires an adequate amount of calcium from food. Terrestrial organisms obtain calcium through their diet, while marine organisms absorb it through their skin.
Due to modern dietary habits, calcium intake has significantly decreased. Those who do not consume enough vegetables, fruits, or dairy products often have to take calcium-rich dietary supplements. The average Hungarian consumes 400-600 mg of calcium daily, while the required amount ranges between 1000-1500 mg, depending on the individual’s age and gender. Pregnant women, in particular, require higher calcium intake, as this mineral is essential for fetal development.
Calcium deficiency negatively impacts not only bone health but also other functions in the body. Low calcium intake affects cardiovascular health as well, making it important for everyone to ensure an adequate amount of calcium in their diet.
The Role of Calcium in Cardiovascular Health
Numerous studies support that adequate calcium intake contributes to bone health, but it also plays a key role in preventing cardiovascular problems. Consuming 1-1.5 grams of calcium daily positively affects cardiovascular health by helping to reduce high blood pressure and easing the heart’s workload. An Australian study spanning over a decade found that postmenopausal women who consumed enough calcium experienced half the rate of cardiovascular complications compared to those who did not receive adequate calcium supplementation.
It is important to note that the positive correlation between calcium intake and cardiovascular mortality has long been misinterpreted. A New Zealand study, based on a specific methodology, reached erroneous conclusions, as many participants did not follow medical instructions, rendering the data unreliable. Péter Lakatos, an endocrinologist at Semmelweis University, pointed out that cardiovascular diseases likely developed more as a consequence of calcium deficiency.
Overall, calcium is essential not only for bone health but also for maintaining cardiovascular health. Adequate calcium intake is crucial for long-term health preservation, which is why it is important to consciously pay attention to our diet and, if necessary, to calcium supplementation.
