Our assessment

Our assessment: Based on the data provided, this product contains the mineral calcium. The evidence shows that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, the data does not specify the exact dosage of calcium in Jarrow Formulas Melatonin Sustain, so you should refer to the product label for precise intake levels.

How it works

Think of calcium as a structural foundation for your bones and a signal regulator for your nerves and muscles. It works by supporting bone density and mineral deposition, and it also helps facilitate muscle relaxation and nerve signaling throughout your body [NIH ODS].

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplement categories [FDA data]. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our recommendation: Check the product label for the exact calcium content per serving. If you take calcium, be aware of potential interactions with medications like thyroid hormone or certain antibiotics. Data not available on specific side effect counts for this product from the FDA data provided. Always consult your healthcare provider before starting a new supplement, especially if you have kidney issues or take prescription medications [NIH ODS].
