Nature Made Melatonin 3 mg
Brand: Nature Made · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Nature Made Melatonin 3 mg contains one active ingredient: Calcium. Our assessment is that this product is not a standard melatonin supplement, but rather a calcium supplement. For a general audience seeking sleep support, this product would not provide the intended effect of melatonin. Data for the ingredient Calcium is robust, but it is not indicated for sleep.
How it works
Calcium works through bone mineralization, supporting bone density and mineral deposition, and through neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS]. It does not function as a sleep hormone. If you are looking for a supplement to help with sleep onset, this product is not designed for that purpose.
Safety profile
FDA received a total of 592,059 adverse event reports across all products in their database. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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 is clear: This product is not appropriate for sleep support. If you need a calcium supplement, it is effective for bone health, but you should be aware of the potential side effects and medication interactions [NIH ODS]. For sleep concerns, look for a product specifically labeled as melatonin. Data not available for the melatonin content of this product, as the ingredient list shows only calcium.
