Life Extension Melatonin IR/XR
Brand: Life Extension · Form: CAPSULE [E0159]
Our assessment
The evidence shows that the Life Extension Melatonin IR/XR product contains calcium, though the exact amount is not specified on the label provided. Calcium is a well-studied mineral, but we cannot confirm that this product is formulated to deliver meaningful amounts for bone health. You should check the label carefully for the exact calcium content per serving to determine if it meets your needs.
How it works
Think of calcium as a structural builder and signal conductor. It supports bone mineralization by depositing into your bone matrix, and it helps your muscles and nerves relax and communicate properly through neuromuscular relaxation [NIH ODS]. This dual role makes it essential for both skeletal strength and daily physical function.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this exact product are not available in the data. High calcium intakes from supplements may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects of very high calcium levels include 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
Data not available on the specific calcium dose in this product, so we cannot recommend it as a primary calcium source. If you need calcium, choose a product with a known dose and take it separately from medications like thyroid hormone, antibiotics, or osteoporosis drugs to avoid absorption issues [NIH ODS]. For melatonin’s sleep benefits, consult your pharmacist about a standalone melatonin product with clear dosing.
