NutriCology Melatonin 20 mg
Brand: NutriCology · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the data does not support using a 20 mg melatonin product for calcium supplementation. This product contains melatonin, not calcium. For calcium, our assessment is that you should focus on getting this mineral from food and standard supplements, as high intakes carry specific risks [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. Your body needs it for strong bones and proper muscle function.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may 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 need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on side effects specific to this 20 mg melatonin product is not available.
Our recommendation
We recommend you do not use this product for calcium needs. The 20 mg melatonin product you asked about does not contain calcium. For calcium supplementation, data on proper dosing is not available from the provided information. Always discuss with your healthcare provider before starting any new supplement, especially at high doses [NIH ODS].
