Our assessment
The evidence shows that this supplement combines two well-studied ingredients, but the specific brand formulation is not available for review. Our assessment is based on the individual ingredients listed. Melatonin is widely used for sleep support, and magnesium plays a role in muscle relaxation and bone health [NIH ODS]. However, data on this exact product is limited, so we recommend approaching it with informed caution.
How it works
Think of this combination as a dual-action support for rest. Melatonin helps signal your body that it is time to sleep, while magnesium supports neuromuscular relaxation and bone mineralization [NIH ODS]. Together, these ingredients may help you fall asleep more easily and promote deeper muscle relaxation. The magnesium also plays a role in nerve signaling, which can be beneficial for overall calmness [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific counts for this product are not isolated. For the magnesium component, high levels can cause poor muscle tone, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium (if present in the magnesium compound) can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Data on melatonin side effects from the provided information is not available. Always check with your doctor before starting, especially if you take other medications.
Our recommendation
Start by checking your current sleep habits and any medications you take. If you decide to try this supplement, begin with the lowest possible dose. Be aware that magnesium can interact with common antibiotics and thyroid medication [NIH ODS]. For safety, we recommend consulting your healthcare provider if you have kidney issues or take any prescription drugs. Data not available on the optimal dosage for this specific product, so follow the label instructions carefully.
