Bluebonnet Magnesium Citrate
Brand: Bluebonnet · Form: SUPPLEMENT FORM, OTHER [E0172] On Market
Our assessment
The evidence shows that Bluebonnet Magnesium Citrate is a well-absorbed form of magnesium for supporting muscle relaxation and nerve signaling. However, based on the data provided, the ingredient profile lists Calcium, not Magnesium. Our assessment must strictly follow the data: for calcium, the evidence supports bone mineralization and neuromuscular relaxation [NIH ODS]. You should verify the label to confirm you are purchasing a magnesium product, as the data here applies to calcium.
How it works
Think of calcium as a key structural component for your bones and a regulator for your nerves and muscles. It supports bone density through mineralization and helps your muscles relax after contraction [NIH ODS]. For proper function, calcium works closely with other minerals, but the data provided focuses on its role in bone health and nerve signaling.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, side effects from high intake include constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [FDA data] [NIH ODS]. High levels in the blood can also cause poor muscle tone, poor kidney function, and low phosphate levels [NIH ODS]. Some research notes a potential increased risk of heart disease and prostate cancer with very high intakes [NIH ODS].
Our recommendation
Start by confirming your product label contains magnesium citrate as intended. For calcium, the data supports 600 IU daily (the RDA for most adults) but this is not the ingredient in question [NIH ODS]. If you are using this for magnesium, data not available for that specific ingredient. Always take calcium supplements separately from medications like bisphosphonates, tetracycline antibiotics, and levothyroxine to avoid absorption issues [NIH ODS].
