Standard Vitamins Melatonin 3 mg
Brand: Standard Vitamins · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product contains 3 mg of melatonin, but the key ingredient for which we have data is calcium. Our assessment is that calcium is essential for bone health, but you should be aware of the specific risks and interactions associated with this mineral [NIH ODS].
How it works
Think of calcium as a structural builder and a calming signal. It supports bone density and mineral deposition, which is critical for maintaining strong bones. It also plays a role in neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though specific report counts for calcium alone are not available. High calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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] [FDA data].
Our recommendation
Data not available for melatonin-specific dosing recommendations. For calcium, you should be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these, separate your calcium dose by at least two hours. We recommend you consult your healthcare provider before starting this supplement, especially given the potential for serious side effects at high intakes [NIH ODS].
