Source of validity: Scientific
Rating (out of 5): 3

Calcium supplementation for the management of menstrual cramps (dysmenorrhea) is supported by a moderate level of scientific evidence. Several studies suggest that women with calcium deficiencies are more likely to experience severe menstrual cramps, and that calcium supplementation can reduce the intensity of these symptoms. The proposed mechanism is that calcium plays a key role in muscle contraction and nerve transmission; low calcium levels may lead to increased muscle spasms, including those of the uterine muscles during menstruation.

Randomized controlled trials have found that women who took daily calcium supplements reported a significant reduction in menstrual pain compared to those receiving a placebo. For example, a study published in "Obstetrics & Gynecology" (1999) found that women supplementing with 1,200 mg of calcium daily experienced fewer symptoms of premenstrual syndrome, including cramps, over a three-month period. Another study in the "American Journal of Obstetrics and Gynecology" (2000) observed similar benefits.

While calcium supplementation is not universally endorsed as a first-line treatment for menstrual cramps, it is recognized as a supportive therapy, especially in individuals with low dietary calcium intake. Major health organizations, such as the American College of Obstetricians and Gynecologists, acknowledge its potential benefit, although they often recommend it alongside other management strategies. Overall, calcium's use for menstrual cramps is grounded in scientific research, but more large-scale studies could strengthen the evidence base.
