AN Amazing Nutrition Amazing Formulas Melatonin 10 mg

Our assessment

The evidence shows that this product contains 10 mg of melatonin, which is a significantly higher dose than the 0.5 mg to 5 mg commonly studied for sleep. Based on the data provided, we cannot confirm the efficacy or safety of this specific dose for general use. You should approach this supplement with caution, as high-dose melatonin is not universally recommended.

How it works

Melatonin is a hormone that helps regulate your sleep-wake cycle. While specific mechanism data for this product is not available, the ingredient calcium is included on the label. Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, the primary action of melatonin itself is to signal to your body that it is time to sleep. Data not available for the specific mechanism of melatonin at 10 mg.

Safety profile

The FDA has received a total of 592,059 adverse event reports for all dietary supplements, but specific report counts for melatonin or this brand are not available [FDA data]. For the calcium component, high levels can cause constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. You should be aware that taking 10 mg of melatonin daily may lead to morning drowsiness or headaches, though this is not confirmed by the data provided.

Our recommendation

We recommend starting with a much lower dose of melatonin, typically 0.5 mg to 3 mg, taken 30–60 minutes before bed. Because the data for this specific 10 mg product is limited, consult your healthcare provider before use, especially if you take medications such as bisphosphonates, tetracycline antibiotics, or levothyroxine, as calcium can reduce their absorption [NIH ODS]. Data not available for a final safety conclusion on this product.

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.
