Bio-Tech Pharmacal B12-Methyl
Brand: Bio-Tech Pharmacal · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that the active ingredient in Bio-Tech Pharmacal B12-Methyl is calcium, not vitamin B12 as the product name suggests. Based on the data provided, this is a calcium supplement. Our assessment is that calcium is essential for bone health, but the product name may be misleading because the data does not list B12 as an ingredient. You should verify the label carefully before use.
How it works
Calcium acts as a master regulator for your bones and muscles. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling [NIH ODS]. Think of calcium as the key that helps your muscles relax after contracting and keeps your skeleton strong and dense.
Safety profile
FDA received 592,059 total adverse event reports across all products. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels in the blood and urine include 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]. Data not available on specific side effect report counts for calcium alone from the FDA data provided.
Our recommendation
Our recommendation is to confirm the label of Bio-Tech Pharmacal B12-Methyl, as the data shows the ingredient is calcium, not B12. If you are seeking a calcium supplement, be cautious with high doses. Avoid exceeding 2,500 mg daily from all sources to reduce risks of heart disease and kidney problems [NIH ODS]. Take calcium separately from the listed medications by at least two hours to prevent absorption issues [NIH ODS]. If you are looking for vitamin B12, this product may not be appropriate — data not available on B12 content.
