Rating (out of 5): 2

Calcium has traditionally been recommended as a remedy for sleep disturbances, including restless and disturbed sleep. This is primarily based on its role in muscle function, nerve transmission, and the regulation of certain neurotransmitters. Folklore and older medical texts often suggest that calcium, sometimes in combination with magnesium, can help ease nighttime restlessness or muscle cramps that interfere with sleep. It is thought that calcium helps the brain use the amino acid tryptophan to manufacture melatonin, a hormone that induces sleep. However, the direct scientific evidence supporting a significant role for calcium supplementation in improving sleep quality is limited and somewhat inconclusive.

Some small observational studies and older research suggest a link between low calcium intake and sleep disruptions, particularly in populations at risk of deficiency (e.g., postmenopausal women, elderly individuals). Nonetheless, controlled trials specifically investigating calcium supplementation for sleep disorders are scarce, and most have not shown a strong or consistent benefit. The most compelling rationale for calcium’s role comes from its contribution to overall health, which may indirectly support better sleep in deficient individuals. In summary, while traditional wisdom favors calcium for sleep, modern research does not robustly validate its use for this specific purpose.
