Bluebonnet Calcium Citrate plus Magnesium
Brand: Bluebonnet · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that Bluebonnet Calcium Citrate plus Magnesium is a supplement with a well-established role in bone health, primarily due to its calcium content. For most adults, calcium is essential for maintaining bone density and proper nerve signaling [NIH ODS]. However, you should be aware that the total number of FDA adverse event reports for all products is 592,059, which is a very broad figure and does not specifically reflect the safety of this particular product [FDA data].
How it works
Think of calcium as a key structural component for your skeleton. It supports bone mineralization and density, and it also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves send signals correctly [NIH ODS]. The "citrate" form in this product may be easier for some people to absorb, especially those with lower stomach acid.
Safety profile
Data not available on side effects specifically for this product. However, general safety data for calcium indicates that very high intakes can lead to risks. 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Start by assessing your total calcium intake from food and other supplements. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take this supplement at a different time than those medications. Do not exceed the recommended dose on the label without consulting your doctor, as the long-term safety of very high calcium intake is not fully established [NIH ODS].
