Swanson Premium Brand Melatonin 3 mg

Brand: Swanson Premium Brand · Form: CAPSULE [E0159]

Our assessment

Our assessment: The evidence shows that Swanson Premium Brand Melatonin 3 mg is a popular supplement, but the specific product data provided contains no information about melatonin itself. The data available only covers calcium. For the intended supplement, we must rely on general safety monitoring. The FDA received 592,059 total adverse event reports across all supplements, but specific report counts for melatonin are not available in the data provided [FDA data].

How it works

Based on the data provided, this product's mechanism is not described. However, the data does include information on a different ingredient, calcium, which supports bone mineralization and neuromuscular relaxation [NIH ODS]. For melatonin specifically, data on how it works is not available in the provided information.

Safety profile

The safety data provided is for calcium, not melatonin. For calcium, safety concerns include that high intakes might increase the risk of heart disease and prostate cancer. High calcium levels 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]. For Swanson Premium Brand Melatonin 3 mg, specific side effects and report counts are not available in the provided data [FDA data].

Our recommendation

Our recommendation: Without specific data on melatonin's effects, interactions, or safety profile for this product, we cannot provide a confident recommendation. Data on calcium interactions shows it can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For melatonin, data on interactions and proper dosing is not available. You should consult a healthcare provider before use, as the provided information does not support a clear guidance for this specific supplement.
