Sundown Melatonin 5 mg

Brand: Sundown · Form: TABLET [E0155] On Market

Our assessment

The evidence shows that Sundown Melatonin 5 mg is a supplement used to support sleep, but the data on its primary ingredient, calcium, does not directly address melatonin’s effects. Our assessment: You should be aware that the active ingredient in this product is melatonin, not calcium, and the data provided focuses on calcium’s role in bone and nerve health [NIH ODS]. For melatonin-specific benefits, data is not available in the provided information.

How it works

Think of calcium in this product as a supporting mineral — it aids in bone mineralization and neuromuscular relaxation, which may help with overall relaxation before sleep [NIH ODS]. However, the primary sleep-regulating ingredient, melatonin, is not detailed in the data provided. The mechanism of calcium involves supporting bone density and nerve signaling, which can contribute to muscle relaxation [NIH ODS].

Safety profile

FDA received 592,059 total adverse event reports across all supplements, but specific reports for Sundown Melatonin 5 mg are not available in the data. Based on the calcium data, side effects include constipation, nausea, weight loss, and abnormal heart rhythms at high levels [NIH ODS]. High calcium intake may also increase the risk of heart disease and prostate cancer [NIH ODS]. For melatonin-specific side effects, data is not available.

Our recommendation

Start with one tablet of Sundown Melatonin 5 mg about 30 minutes before bed. Be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. If you take any of these, separate doses by at least 2 hours. For melatonin-specific guidance, data is not available — consult your healthcare provider for personalized advice.
