Douglas Laboratories Melatonin 3 mg Sublingual Tablets
Brand: Douglas Laboratories · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a well-studied mineral essential for bone health, but the specific product you asked about — Douglas Laboratories Melatonin 3 mg Sublingual Tablets — contains melatonin, not calcium. Data for calcium is provided, but no data was provided for melatonin in this product. Our assessment is based solely on the calcium data provided, which indicates it plays a critical role in bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton and a signal regulator for your nerves and muscles. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. This makes it vital for maintaining strong bones and preventing muscle cramps or spasms.
Safety profile
FDA received 592,059 total adverse event reports for all supplements in this dataset, but specific report counts for calcium alone are not available. Data indicates that high calcium intakes might increase the risk of heart disease and prostate cancer. High blood and urine calcium levels 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 medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because no data was provided for the Douglas Laboratories Melatonin 3 mg Sublingual Tablets, we cannot make a recommendation for that specific product. For general calcium supplementation, you should not exceed the Tolerable Upper Intake Level without medical supervision, and you should take calcium separately from medications like thyroid hormone or antibiotics to avoid absorption issues [NIH ODS]. Always consult your healthcare provider before starting any new supplement, especially if you have a history of kidney stones, heart disease, or take prescription medications.
