Specialty Pharmacy Melatonin 0.5 mg

Our assessment

The evidence shows that this product contains melatonin 0.5 mg, but the data available for review pertains to calcium, not melatonin. Based on the information provided, we cannot assess the benefits or risks of this specific melatonin product. The data on calcium, however, is well-documented. Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. You should be aware that high calcium intakes may increase the risk of heart disease and prostate cancer [NIH ODS].

How it works

Calcium acts as a master regulator for bone health, aiding in bone density and mineral deposition. It also supports muscle relaxation and nerve signaling [NIH ODS]. For the melatonin in this product, specific data on its mechanism of action is not available in the provided information.

Safety profile

FDA received 592,059 total adverse event reports across all supplements in the dataset, but specific report counts for this melatonin product are not provided. For calcium, side effects from high intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. High levels of calcium in the blood and urine can also cause poor muscle tone, poor kidney function, and a high risk of death from heart disease [NIH ODS]. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Data not available for a recommendation specific to melatonin 0.5 mg. If you are considering a calcium supplement, consult your healthcare provider to determine the appropriate dosage for your needs and to check for potential interactions with your medications [NIH ODS].
