Sundown Naturals Maximum Strength Melatonin 10 mg
Brand: Sundown Naturals · Form: CAPSULE [E0159]
Our assessment
Our assessment: The evidence shows that Sundown Naturals Maximum Strength Melatonin 10 mg is a high-dose melatonin supplement. Melatonin is a hormone that helps regulate your sleep-wake cycle. For this specific product, the key data relates to the calcium it contains, not the melatonin itself. The data for melatonin-specific benefits and risks is limited in the provided information.
How it works
Melatonin works by signaling to your body that it is time to sleep. The calcium in this supplement plays a separate role. It supports bone mineralization and neuromuscular relaxation [NIH ODS]. Think of calcium as a structural builder for your bones and a signal regulator for your nerves and muscles [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific data for melatonin is not available here. For calcium, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels can cause constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Start with a lower dose of melatonin (1-3 mg) before using a 10 mg product. Be aware that calcium supplements can interact with other medications. If you take any of the listed medications, take them at least 2 hours apart from this supplement [NIH ODS]. Consult your doctor before starting, especially if you have a history of kidney problems or heart disease.
