Life Extension Melatonin 300 mcg
Brand: Life Extension · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but our assessment is that this product, Life Extension Melatonin 300 mcg, does not contain calcium as an active ingredient. Data for calcium is provided for general context, not for this specific supplement. For this product, you are considering melatonin at a low dose of 300 mcg. Data on the specific benefits of melatonin at this dose is not available in the provided data.
How it works
Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, this function is not relevant to the melatonin product you are asking about. For calcium specifically, think of it as a structural building block for your skeleton and a signal conductor for your nerves and muscles [NIH ODS].
Safety profile
The FDA received 592,059 total adverse event reports across all dietary supplements, but specific report counts for this melatonin product are not available [FDA data]. For calcium, safety data shows that high intakes might increase the risk of heart disease and prostate cancer, and can cause side effects like constipation, nausea, and abnormal heart rhythms [NIH ODS].
Our recommendation
Our recommendation is that you focus on the product’s actual ingredient: melatonin. Since specific data for 300 mcg melatonin is not available here, we cannot make a definitive statement about its efficacy or safety. For general calcium guidance, the data shows it can reduce absorption of medications like bisphosphonates and levothyroxine, so take calcium separately from those drugs [NIH ODS]. For this melatonin product, consult your healthcare provider for personalized advice.
