Our assessment
The evidence shows that the active ingredient in this product, calcium, is essential for bone health, but the data for this specific product is limited. Our assessment: Based on the available information, we cannot make a specific recommendation for GNC Melatonin 3, as the data provided pertains to calcium, not melatonin. Data not available for melatonin-specific effects from this product.
How it works
Calcium works through bone mineralization, supporting bone density and mineral deposition, and through neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
The FDA adverse event database contains a total of 592,059 reports across all products, but specific report counts for this product are not available. For calcium, safety data shows that high 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Because this product is labeled GNC Melatonin 3 but the ingredient data provided is for calcium, we cannot offer a confident recommendation. Data not available for melatonin dosing or effects. If you are considering calcium supplementation, discuss with your healthcare provider, especially if you take medications that may interact [NIH ODS].
