What is Calcium and Why is it Important?
Calcium is an essential mineral required by the human body for critical functions such as nerve transmission, muscle contraction, blood clotting, and maintaining healthy bones and teeth. It is the most abundant mineral present in the body, accounting for around 2% of our total body weight.
Calcium is primarily stored in our bones and teeth, where it combines with phosphate to form a mineral known as hydroxyapatite, which provides strength and stability to our skeletal system. Proper calcium intake is vital for maximizing bone density and reducing the risk of fractures, especially in older adults.
In addition to bone health, calcium plays a crucial role in muscle function, including heart muscle, by facilitating communication between nerves and muscles. It also helps regulate blood pressure, supports healthy nerve function, and enables proper blood clotting.
Although the body requires only a small amount of calcium to perform these functions, it is important to ensure that we meet our daily calcium requirements for optimal health and wellbeing.
Recommended Calcium Intake
Calcium is an essential mineral that plays a vital role in maintaining healthy bones, muscle function, and nerves. According to the National Institutes of Health (NIH) a recommended calcium intake differs by age and gender and can be presented in the following table:
Age (years) | Recommended Calcium Intake (mg/day) |
0-6 months | 200-260 |
7-12 months | 260 |
1-3 years | 700 |
4-8 years | 1000 |
9-13 years | 1300 |
14-18 years | 1300 |
19-50 years | 1000 |
51-70 years (men) | 1000 |
51-70 years (women) | 1200 |
71+ years | 1200 |
Pregnant or lactating (14-18 years) | 1300 |
Pregnant or lactating (19-50 years) | 1000 |
It is important to note that exceeding the recommended daily calcium intake may not provide additional benefits and could lead to risks associated with excessive calcium intake discussed in the previous section. Consult with your healthcare provider to determine the proper amount of calcium that should be consumed daily.
Excessive Calcium Intake: Dangers and Side Effects
While calcium is an essential mineral for optimal health, consuming too much of it can be harmful. Excessive calcium intake can have a range of detrimental effects on numerous bodily systems, including the cardiovascular, renal, and digestive systems.
The dangers of too much calcium in the body center around its impact on cardiovascular health. Excess calcium can cause arterial plaques to form, increasing the risk of heart disease and stroke. Additionally, excessive calcium intake may lead to renal complications, such as kidney stones and chronic kidney disease, and negatively affect digestive health as well.
Side effects of calcium overdose can present in varying forms. These generally include digestive symptoms, such as constipation, bloating, and nausea, and can gradually evolve into more serious conditions, like hypercalcemia, characterized by high calcium levels in the blood, and hypocalcemia, resulting from low levels of calcium in the blood. The risks associated with overdoing calcium intake are primarily avoidable and stem from a lack of regulation or a misguided assumption that consuming copious amounts of calcium will yield results more quickly.
It is important to ensure that one's calcium intake remains within the recommended limits to prevent the accumulation of excess calcium in the body.
Is "Death by Calcium" Real?
There have been concerns regarding the possibility of "death by calcium" due to excessive intake of calcium. However, this is a myth that has been debunked by scientific research. Calcium toxicity is rare, and severe cases usually stem from underlying conditions or supplement abuse rather than dietary calcium intake alone.
The National Institutes of Health notes that the daily intake of calcium through diet and supplements should not exceed 2,500 mg. This is because excessively high levels of calcium in the blood can lead to hypercalcemia, which can cause kidney stones, irregular heartbeat, and even coma or death in severe cases. Nevertheless, the likelihood of reaching such high levels through dietary calcium alone is low.
Calcium level in blood (mg/dL) | Symptoms |
11-12 | fatigue, headaches, dry mouth, nausea, vomiting, constipation, muscle weakness |
Above 12 | kidney stones, bone pain, depression, memory loss, confusion, coma |
It is important to note that calcium is a vital nutrient for the body and plays a crucial role in various bodily functions. Hence, maintaining adequate levels through a balanced diet and safe supplement use is essential to ensure optimal health.
"Calcium toxicity is a rare condition, and most people can safely consume calcium-rich foods as part of a balanced diet without risk. However, excessive intake of calcium supplements and undiagnosed underlying conditions can lead to toxicity and severe health consequences. Therefore, it is essential to consult healthcare professionals to determine individual calcium needs."
Conditions Associated with Calcium Imbalance
A calcium imbalance, whether too low or too high, can cause various health issues and complications in the body. Hypercalcemia occurs when the calcium level in the blood is too high, while hypocalcemia is a deficiency of calcium in the blood.
Some of the symptoms of hypercalcemia include fatigue, nausea, constipation, excessive thirst, and confusion. It can also lead to kidney stones, bone pain, and even cardiac arrest in severe cases. Hypocalcemia can cause muscle spasms, numbness, and tingling in the hands and feet, and in severe cases, seizures and heart issues.
The causes of these imbalances can vary, ranging from underlying medical conditions such as kidney disease or thyroid issues to certain medications and supplements. Calcium imbalance can also result from an unhealthy diet or over-supplementation.
A comprehensive blood test can detect calcium imbalances in the body. If you suspect that you may have a calcium imbalance, it is essential to consult with a healthcare professional for a proper diagnosis and treatment plan.
