Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Calcium plays a well-established physiological role in muscle function, including maintaining normal muscle tone. Muscle contraction is initiated by the release of calcium ions within muscle cells, which interact with the contractile proteins actin and myosin. Inadequate calcium levels (hypocalcemia) can lead to neuromuscular irritability, resulting in muscle cramps, spasms, or tetany—a sustained increase in muscle tone. Numerous clinical studies and medical textbooks document that correcting calcium deficiency can resolve these symptoms and restore normal muscle tone. Thus, in individuals with low muscle tone due to calcium deficiency, supplementation is scientifically validated as an effective treatment. However, it is important to note that calcium supplementation will not benefit muscle tone in individuals with normal calcium levels or those whose muscle hypotonia is due to other causes (e.g., neurological disorders or muscle disease). Guidelines from reputable medical organizations, such as the Endocrine Society and the National Institutes of Health, recommend calcium supplementation in cases of hypocalcemia to prevent or treat neuromuscular symptoms. In summary, there is robust scientific evidence supporting the use of calcium to treat lack of muscle tone specifically when it is caused by calcium deficiency, but not for all causes of hypotonia.
