Our assessment
The evidence shows that GNC Calcium Plus With Magnesium is a well-formulated supplement for supporting bone health. Our assessment is that the calcium content is the primary active ingredient, and it is effective for maintaining bone density when used correctly [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation by helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for products like this one. Specific risks from high calcium intake include constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms. High levels in the blood and urine can also lead to poor muscle tone, poor kidney function, and a high risk of death from heart disease [FDA data] [NIH ODS].
Our recommendation
We recommend taking this supplement with food to improve absorption. Be aware that calcium can reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, and levothyroxine, so take it at a different time of day [NIH ODS]. Start with the labeled dose and monitor for any digestive discomfort.
