Brand: Spring Valley · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market
Our assessment
The evidence shows that this product provides 5 mg of melatonin per serving, which is a common dosage for sleep support. However, data on the specific ingredient calcium is provided in the data set. For this product, the active ingredient is melatonin, and the data for calcium does not apply here. Our assessment: Data not available for melatonin-specific effects from the provided data.
How it works
Think of melatonin as your body's natural sleep signal. While the data provided does not include a mechanism for melatonin, the data set does include calcium, which works through bone mineralization to support bone density and neuromuscular relaxation to support muscle relaxation and nerve signaling [NIH ODS]. For melatonin, data not available.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, side effects include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS] [FDA data]. For melatonin-specific side effects, data not available.
Our recommendation
Start with the lowest effective dose, which may be lower than 5 mg. Be aware that calcium supplements can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For this specific melatonin product, data not available for a targeted recommendation. Consult your healthcare provider before starting any new supplement.
