Nature's Bounty Maximum Strength Melatonin 10 mg
Brand: Nature's Bounty · Form: CAPSULE [E0159]
Our assessment
The evidence shows that while calcium is essential for bone health, the available data does not support the use of a 10 mg melatonin supplement for calcium needs. You are asking about a specific product, but the ingredient data provided is for calcium, not melatonin. Our assessment is that this product label indicates a 10 mg dose of melatonin, which is a very high dose. For the purpose of this analysis, we can only discuss the calcium data provided, and that data does not apply to this product.
How it works
Based on the data provided, calcium works through bone mineralization, supporting bone density and mineral deposition. It also aids in neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS]. This mechanism is specific to calcium and is not how melatonin functions.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes might 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]. Data not available for side effects of the melatonin product itself.
Our recommendation
Data not available to make a recommendation for this specific melatonin product. For calcium, the data shows it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should speak with your healthcare provider before starting any new supplement, especially at a high dose like 10 mg of melatonin.
