Life Extension Melatonin 500 mcg
Brand: Life Extension · Form: CAPSULE [E0159]
Our assessment
Our assessment: The evidence shows that while calcium is essential for bone health, the data provided does not support using this specific product, Life Extension Melatonin 500 mcg, for that purpose. The product label lists melatonin, not calcium. For calcium supplementation, you should be aware that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Calcium works through bone mineralization, helping to support bone density and mineral deposition, and through neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS]. The product you asked about, however, contains melatonin, not calcium, so this mechanism does not apply to it.
Safety profile
Data not available for this specific product. The FDA has received 592,059 total adverse event reports across all supplements, but specific side effects for this product are not listed in the data provided. For calcium, high levels in the blood and urine can cause 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].
Our recommendation
Our recommendation: Because the data provided is for calcium and the product is melatonin, we cannot recommend this product for calcium supplementation. For calcium, be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should consult a healthcare professional about your specific needs.
