Puritan's Pride Melatonin 3 mg
Brand: Puritan's Pride · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Puritan's Pride Melatonin 3 mg is a supplement intended to support sleep, but its primary active ingredient is melatonin. However, based on the data provided, the core nutritional ingredient is calcium, which plays a distinct role in the body. Our assessment: You should understand that this product contains a dose of melatonin that may help with sleep timing, but the data we have focuses on calcium, not melatonin. For calcium, the RDA is not specified in this data, but it is a critical mineral for bone health and nerve function [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone mineralization and density, and it also helps your muscles relax and your nerves send signals properly [NIH ODS]. If you are taking this product for sleep, melatonin's role is to signal your body that it is time to rest, though specific data on melatonin's mechanism is not available here. The calcium in this supplement works by supporting neuromuscular relaxation, which may indirectly promote a calm state [NIH ODS].
Safety profile
Data not available for melatonin-specific adverse events. However, the FDA has received a total of 592,059 adverse event reports across all supplements in the database [FDA data]. For calcium specifically, safety concerns include that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. You should be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Start by consulting your healthcare provider before taking this supplement, especially if you take any of the medications listed above. For sleep, 3 mg of melatonin is a common starting dose, but data on its specific benefits and risks is not provided. For calcium, ensure you are not exceeding recommended levels from diet and other supplements combined. Choose a product that clearly lists all ingredients and dosages on the label, as this product's label is not specified [See label].
