Our assessment
The evidence shows that a balanced calcium and magnesium supplement like Bluebonnet Calcium Magnesium 1:1 Ratio can support bone density and muscle relaxation [NIH ODS]. However, you need to be cautious with calcium dosing, as high intakes are linked to potential risks including heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a key structural component for your bones, supporting bone mineralization and density [NIH ODS]. Magnesium works alongside it to promote neuromuscular relaxation, helping your muscles and nerves signal effectively [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes can cause constipation, nausea, and poor muscle tone [NIH ODS]. More serious risks from elevated blood and urine calcium include poor kidney function, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Data on magnesium-specific side effects for this product is not available.
Our recommendation
Start by assessing your dietary calcium intake before adding this supplement. Calcium can reduce absorption of medications including bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Take this supplement at least two hours apart from those medications. For most adults, aim to meet but not exceed calcium recommendations through food first [NIH ODS].
