Our assessment
The evidence shows that while calcium is a well-documented mineral for bone health, the specific product you are looking at, Life Extension Melatonin 300 mcg, does not contain calcium. Our assessment of the data provided is that we can only analyze the ingredient calcium, as no other ingredient data is available for this product. You should be aware that the data for calcium is extensive, but it does not apply to this melatonin supplement.
How it works
Calcium works as a master regulator for your skeleton and nervous system. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for Life Extension Melatonin 300 mcg. For the ingredient calcium, the FDA received a total of 592,059 adverse event reports across all supplements. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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
Since this product is Life Extension Melatonin 300 mcg, and the only data provided is for the mineral calcium, we cannot make a recommendation about this specific supplement. For calcium, the RDA should be met through diet first. If you are considering a calcium supplement, be aware of the potential for high intake to cause serious side effects and drug interactions [NIH ODS]. For the melatonin product, data on its efficacy and safety is not available in the provided information.
