Nutricost Melatonin 5 mg
Brand: Nutricost · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that a 5 mg dose of melatonin is a common starting point for sleep support, but it is not without important considerations. Based on the data available, calcium is listed as the primary ingredient in the provided product information, not melatonin. This discrepancy means we must be cautious. Our assessment: the product label you referenced does not match the ingredient data provided, so we will analyze the ingredient listed—calcium—at the 5 mg dose level. For general sleep concerns, 5 mg of melatonin is a moderate dose, but the data provided does not confirm this product contains melatonin.
How it works
Calcium functions as a master regulator for bone mineralization, supporting bone density and mineral deposition, and it also aids neuromuscular relaxation, which supports muscle relaxation and nerve signaling [NIH ODS]. This mechanism is critical for maintaining strong bones and proper muscle function. Think of calcium as a key player in your body's structural and signaling systems, not a direct sleep aid.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this exact product are not available. For calcium, safety concerns include that 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you verify the exact product label, as the data provided lists calcium, not melatonin, as the active ingredient. If you are seeking a calcium supplement, a 5 mg dose is far below the RDA for calcium (1,000-1,200 mg daily for most adults) and would be ineffective for bone health. Data not available on the appropriate dose for melatonin from this product. Start by confirming the ingredient list on your bottle. If the product contains calcium, do not rely on it for sleep support. Always consult a healthcare professional before starting any new supplement, especially if you take medications that interact with calcium [NIH ODS].
