Douglas Laboratories Melatonin 3 mg Sublingual Tablets
Brand: Douglas Laboratories · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it requires careful management. Our assessment is that you should not use this product for melatonin unless a calcium deficiency has been confirmed by a healthcare provider, as the data on calcium carries significant safety considerations [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton and a signal conductor for your nerves and muscles. It supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Start by getting your calcium levels tested before supplementing. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
