Allergy Research Group B12 Methylcobalamin
Brand: Allergy Research Group · Form: LOZENGE [E0174]
Our assessment
The evidence shows that while the product is labeled as Allergy Research Group B12 Methylcobalamin, the only ingredient data provided is for calcium. For the ingredient calcium, our assessment is that it plays a well-established role in bone health, but the safety profile requires careful attention to dosing and potential interactions. Data not available for B12 methylcobalamin specifically.
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and also aids in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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 [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Given the data provided, we cannot recommend this specific product for B12 supplementation, as no data on B12 methylcobalamin was supplied. If you are considering a calcium supplement, be aware of the potential for serious side effects at high intakes and the significant medication interactions listed above. Always consult your physician before starting a new supplement, especially if you take prescription medications [NIH ODS].
