Bluebonnet Calcium Magnesium Plus Boron

Our assessment

The evidence shows that Bluebonnet Calcium Magnesium Plus Boron is a solid choice for supporting bone health, but you need to be mindful of the total calcium you consume from all sources. The key ingredient, calcium, plays a vital role in bone mineralization, helping to build and maintain strong bones by supporting bone density and mineral deposition [NIH ODS].

How it works

Think of calcium as a structural building block for your skeleton. It works through a process called bone mineralization, where calcium is deposited into the bone matrix to maintain density and strength. Additionally, calcium supports your nervous system by aiding in neuromuscular relaxation and proper nerve signaling [NIH ODS]. This means it not only helps keep your bones sturdy but also supports your muscles' ability to relax after contracting.

Safety profile

Data not available on specific adverse events for this product. However, based on the calcium ingredient, you should be cautious about total intake. Some research suggests that very high calcium intakes might increase the risk of heart disease and prostate cancer. Extremely high levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, and abnormal heart rhythms [NIH ODS]. The total number of adverse event reports across all products in the FDA database is 592,059 [FDA data]. This supplement may also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].

Our recommendation

Our assessment: This product can be a helpful part of your bone health regimen, but you must account for the calcium you get from food and other supplements. To avoid potential risks, take this supplement at a different time than any prescription medications you use. Start with one serving per day and monitor how you feel. If you have a history of kidney stones or heart conditions, consult your healthcare provider before starting this supplement [NIH ODS].
