Our assessment
The evidence shows that MBi Nutraceuticals B12 Booster contains calcium, a mineral essential for bone health and muscle function. While calcium is a well-supported nutrient, our assessment is that you should be cautious about adding this supplement to your routine without first reviewing your current calcium intake from food and other supplements, as high intakes carry significant health risks [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, which helps keep your bones strong. Additionally, calcium plays a role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly after they fire [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all products in its database, though specific report counts for this product are not available. For calcium specifically, the data shows that high intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium in your 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to not start this supplement without first evaluating your total daily calcium intake from all sources. The risks of exceeding the upper limit are serious. If you are taking any prescription medications — especially thyroid medication, antibiotics, or osteoporosis drugs — take this supplement at least 2 hours apart from those medications to avoid absorption issues [NIH ODS]. Consult your healthcare provider before use.
