Our assessment
Our assessment is that this specific product, Douglas Laboratories Melatonin 3 mg, contains calcium based on the label information provided. Calcium is a critical mineral for bone health, but the data shows that taking this supplement without careful consideration of your total intake may carry risks. You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a builder and regulator for your body. It supports bone mineralization by helping deposit minerals into your bone structure, and it also plays a key role in neuromuscular relaxation, which helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports for products in this category. Specific risks from high calcium levels in the blood and urine include 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you do not take this supplement without first evaluating your total daily calcium intake from all sources, including food and other supplements. Because high levels carry significant risks, you should consult your healthcare provider to check if calcium supplementation is right for you, especially if you take any of the medications listed above [NIH ODS].
