Our assessment
The evidence shows that calcium is an essential mineral for bone health, but supplementation requires careful consideration. Our assessment: If you are not getting enough calcium from food, a supplement can help, but you must be mindful of the total amount you take daily. Data on your specific product, Jarrow Formulas Melatonin Sustain, is not available regarding its calcium content or claims. We are analyzing the ingredient calcium based on available data.
How it works
Think of calcium as the structural building block for your bones and teeth. It supports bone mineralization and density, and it also plays a critical role in neuromuscular relaxation and nerve signaling [NIH ODS]. Your body needs a steady supply to keep these systems running smoothly.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for calcium alone are not provided. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels in the blood or urine can cause poor muscle tone, poor kidney function, 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 medications such as bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
First, assess your dietary calcium intake from foods like dairy, leafy greens, and fortified products. If you need a supplement, choose one that provides no more than 500-600 mg of elemental calcium per dose for better absorption. Be aware of total daily intake from all sources (food and supplements). If you take any of the medications listed, separate your calcium supplement by at least two hours [NIH ODS]. Consult your doctor before starting any new regimen.
