Sundown Naturals Maximum Strength Melatonin 10 mg
Brand: Sundown Naturals · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Sundown Naturals Maximum Strength Melatonin 10 mg is a high-dose supplement. For calcium, which is a key mineral in many supplements, the data confirms it supports bone density and nerve signaling [NIH ODS]. However, you should be aware that high calcium intakes may increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a nerve relaxant. It works through bone mineralization, helping deposit minerals into your skeleton, and it supports neuromuscular relaxation to help your muscles and nerves function properly [NIH ODS].
Safety profile
Data not available for melatonin-specific adverse events for this product. For calcium, side effects from high levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. The FDA received a total of 592,059 adverse event reports across all supplements [FDA data].
Our recommendation
Start by discussing this high-dose melatonin with your healthcare provider, especially if you take other medications. Be cautious with calcium-containing supplements due to the risks of high intake and drug interactions [NIH ODS]. Do not exceed recommended doses without professional guidance.
