Life Extension Melatonin 3 mg
Brand: Life Extension · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that calcium is essential for bone health and nerve function, but the data does not support using a melatonin 3 mg product as a source of calcium. Our assessment: for calcium needs, you should rely on dietary sources or dedicated calcium supplements, not this melatonin product. The data for calcium is robust, but it is not relevant to this specific supplement [NIH ODS].
How it works
Calcium acts as a master regulator for your body's structure and signaling. It supports bone mineralization, helping to deposit minerals into your bone density, and it also supports neuromuscular relaxation, which is critical for muscle and nerve function [NIH ODS]. However, this product is formulated with melatonin, not calcium, so these mechanisms do not apply here.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes can increase the risk of heart disease and prostate cancer. High levels in the blood and urine may cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Data on side effects for this specific melatonin product are not available.
Our recommendation
Our recommendation: Do not use this melatonin 3 mg product for calcium supplementation. If you need calcium, choose a dedicated calcium supplement and be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For melatonin, consult your healthcare provider for appropriate dosing. Data not available for this product's specific benefits or risks.
