Sundown Naturals Melatonin 3 mg
Brand: Sundown Naturals · Form: TABLET [E0155]
Our assessment
The evidence shows that Sundown Naturals Melatonin 3 mg contains one key active ingredient: calcium. As a clinical pharmacist, I want to be direct with you: this product is not a standard melatonin supplement, and the data provided does not allow us to evaluate it as a sleep aid. Our assessment focuses solely on the calcium content, as that is the only ingredient data available.
How it works
Calcium plays two primary roles in your body. First, it supports bone mineralization, helping maintain bone density and mineral deposition. Second, it aids neuromuscular relaxation, which means it helps your muscles relax and supports nerve signaling [NIH ODS]. Without data on melatonin itself, we cannot comment on how this product might affect your sleep cycle.
Safety profile
Data not available for melatonin-specific adverse events from this product. For calcium, high intakes may 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]. The total adverse event reports across all FDA-tracked products is 592,059, but this number is not specific to this supplement [FDA data].
Our recommendation
Because the provided data only includes calcium information and no melatonin-specific studies, I cannot recommend Sundown Naturals Melatonin 3 mg for sleep support. If you are considering this for insomnia or jet lag, please consult your healthcare provider first. Calcium can reduce absorption of medications including bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Always check with a pharmacist before starting any new supplement.
