ShopRite Melatonin 3 mg

Our assessment

The evidence shows that while the ShopRite Melatonin 3 mg product is labeled for sleep support, our analysis must focus strictly on the data provided. The primary ingredient listed in the data is Calcium, not Melatonin, which creates a critical discrepancy. Based on the data available, this product appears to be a calcium supplement, not a melatonin supplement. You should verify the label on your specific bottle to confirm the active ingredient.

How it works

If this product contains calcium, it works by supporting bone mineralization and neuromuscular relaxation — helping your bones maintain density and your muscles relax properly [NIH ODS]. For true melatonin function, which regulates your sleep-wake cycle, data is not available for this specific product.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplements, though specific reports for this product are not available [FDA data]. For calcium specifically, high intakes may cause constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce absorption of medications such as tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

First, check the product label to confirm you have melatonin 3 mg — the data provided does not match that claim. If it is calcium, you should take it with food for best absorption and separate it from thyroid medication or antibiotics by at least 2 hours [NIH ODS]. For sleep support, data for melatonin from this specific product is not available. Always consult your pharmacist or doctor before starting any new supplement.

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
