Natural Factors Stress-Relax Melatonin 10 mg Chewable
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains 10 mg of melatonin per serving, which is a high dose. For most adults, starting with a lower dose is typically recommended. Data on calcium, a separate ingredient, shows it supports bone density and nerve signaling [NIH ODS]. However, for this specific melatonin product, long-term safety data at this dosage level is not available from the provided information.
How it works
Melatonin is a hormone your body naturally produces to regulate your sleep-wake cycle. Think of it as a natural signal that tells your brain it is time to sleep. A 10 mg dose is considered a high dose and may be more than what is needed to achieve this effect for most people. For comparison, calcium works differently, supporting neuromuscular relaxation and bone mineralization [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all dietary supplements, but specific report counts for melatonin or this exact product are not available in the provided data. High calcium intakes can lead to constipation, nausea, and abnormal heart rhythms, but these side effects are not directly linked to melatonin [NIH ODS]. For this product, specific side effect data with report counts is not available.
Our recommendation
Start with a lower dose of melatonin, typically 0.5 mg to 5 mg, before considering 10 mg. Consult your doctor before use, especially if you take medications like blood thinners or have an autoimmune condition. This product is best used for short-term sleep issues, not as a long-term solution. If you have questions about calcium, separate guidance is available [NIH ODS].
