Calcium

Calcium is potentially the thing that causes all of the problems—allergies, cancer, heart attacks—but when calcium is regulated properly, it protects against all of those things 1. The regulation of calcium is central to the organism's function, with the parathyroid hormone (PTH) playing a key role in maintaining proper blood calcium levels 2. When calcium intake is deficient, PTH increases to maintain blood calcium levels, but this can lead to the removal of calcium from bones 2. Conversely, excessive calcium intake can suppress PTH, leading to potential problems 2.

Calcium is a powerful stimulant to metabolism, increasing the body's requirement for nutrients such as Vitamin A 2. This can lead to acne in some individuals, particularly those who consume dairy products 2. The relationship between calcium, PTH, and metabolism is complex, and further research is needed to fully understand its implications 2.

The distribution of calcium in the body is unique, with high concentrations found in both hard and soft tissues 2. This is in contrast to other minerals, which tend to be more concentrated in specific tissues 2. The regulation of calcium is also closely tied to the parathyroid glands, which produce PTH to maintain proper blood calcium levels 2.

In terms of blood tests, a low PTH level can indicate high calcium levels, while a high PTH level can indicate low calcium levels 8. This highlights the complex relationship between calcium and PTH, and the need for careful regulation of both to maintain proper bodily function 2.
