Allergy Research Group Melatonin 20 mg
Brand: Allergy Research Group · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: The evidence shows that this product contains 20 mg of melatonin, which is a very high dose. For comparison, typical melatonin supplements are often 0.5 mg to 5 mg. Starting with such a high dose is not recommended without specific guidance from your healthcare provider. Data on the long-term safety of this specific dose is limited.
How it works
Melatonin is a hormone your body naturally produces to regulate your sleep-wake cycle. Think of it as a darkness signal for your brain, telling your body it is time to prepare for sleep. While the data for this product focuses on melatonin, it is important to note that calcium, a separate ingredient, supports bone mineralization and neuromuscular relaxation [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though specific reports for this product are not isolated. For the ingredient calcium, high intakes can lead to risks such as constipation, nausea, weight loss, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. For melatonin at this high dose, side effects data is not available from the provided sources.
Our recommendation
Our recommendation: Do not start with a 20 mg dose of melatonin. Begin with a much lower dose, such as 1 mg to 3 mg, taken 30-60 minutes before bed. Always consult your doctor before starting any new supplement, especially at high doses, to review potential interactions with your medications and health conditions [NIH ODS].
