Jarrow Formulas Melatonin Sustain
Brand: Jarrow Formulas · Form: TABLET [E0155]
Our assessment
The evidence shows that Jarrow Formulas Melatonin Sustain contains calcium, a mineral essential for bone health and nerve function. However, the data provided does not include specific information on the melatonin content or the "sustain" release mechanism of this product. For the calcium component, our assessment is that it supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a building block for your bones and a signal regulator for your nerves. It supports bone density through mineral deposition and helps your muscles relax and nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Signs of excessive calcium include 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]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the melatonin-specific dosing or release characteristics of this product. For the calcium component, ensure your total daily intake from all sources does not exceed safe upper limits. If you take prescription medications such as thyroid hormone or antibiotics, separate your calcium supplement by at least two hours [NIH ODS].
