Bluebonnet Calcium Plus Magnesium
Brand: Bluebonnet · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Bluebonnet Calcium Plus Magnesium is a straightforward supplement for supporting bone health, but it requires careful use. The data confirms that calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as the structural building block for your bones and a signal regulator for your nerves. It supports bone density through mineral deposition and helps your muscles relax after contracting [NIH ODS]. This product combines calcium with magnesium, which often works alongside calcium for muscle and nerve function.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements in this category. For calcium specifically, high levels 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 [FDA data] [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by evaluating your total daily calcium intake from food and other supplements. Do not exceed the tolerable upper intake level without medical supervision. Take this supplement with food to improve absorption, and separate it from any thyroid medication or antibiotics by at least 4 hours [NIH ODS].
