Our assessment
The evidence shows that while calcium is essential for health, this product's "Melatonin Extra" formula is not directly linked to the calcium data provided. Based on the ingredient list, our assessment is that you should evaluate this supplement based on its intended purpose—sleep support—rather than calcium content. Data for the specific melatonin formulation in this product is not available for a full clinical assessment.
How it works
Calcium plays a key role in bone mineralization, helping support bone density and mineral deposition. It also supports neuromuscular relaxation, which aids muscle relaxation and nerve signaling [NIH ODS]. However, for a melatonin-based product, you should understand that melatonin primarily helps regulate your sleep-wake cycle. The specific mechanism for this product's "Extra" formulation is not detailed in the data.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific reports for this product are not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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]. Side effects from the melatonin component are not specified in the provided data.
Our recommendation
Given that the product is labeled "Melatonin Extra" and no specific data on its exact formulation is available, we recommend you consult your healthcare provider before starting this supplement. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Since full safety data for this specific product is not available, proceed with caution and under medical supervision.
