Our assessment
The evidence shows that calcium, a key mineral in Nutrina CalMac with Melatonin, plays a well-documented role in bone health. However, you should be aware of important safety considerations before taking this supplement. The FDA has received a total of 592,059 adverse event reports related to products in this category, though specific report counts for each potential side effect are not broken out in that total [FDA data].
How it works
Calcium acts as a master regulator for your body's structural and signaling systems. It supports bone density through bone mineralization and promotes neuromuscular relaxation by aiding muscle relaxation and nerve signaling [NIH ODS]. This makes it essential for maintaining strong bones and a properly functioning nervous system.
Safety profile
High calcium intakes might increase the risk of heart disease and prostate cancer. 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for the specific side effects of melatonin in this product.
Our recommendation
Start by discussing your calcium needs with your healthcare provider, especially if you take any of the medications listed above. Do not exceed the recommended dose on the label, and be cautious about combining this supplement with other calcium-containing products, as high intakes carry significant risks [NIH ODS].
