Our assessment
The evidence shows that this product contains 1 mg of methylcobalamin, a form of vitamin B12. For a general audience, this is a high dose, but the data on its specific benefits and risks is limited to what is provided. We cannot verify claims beyond the ingredient listed on the label.
How it works
While data on methylcobalamin specifically is not available in the provided materials, the ingredient calcium is noted to support bone mineralization and neuromuscular relaxation [NIH ODS]. For vitamin B12, its general role in nerve function and red blood cell formation is well known, but specific mechanism data for this product is not provided.
Safety profile
Data not available for methylcobalamin side effects from the provided FDA data. The total FDA adverse event reports across all supplements is 592,059, but no specific report count for this product is given [FDA data]. For the ingredient calcium, high intakes are linked to risks including constipation, nausea, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].
Our recommendation
Because specific data on methylcobalamin is missing from the provided sources, we cannot make a definitive recommendation on this product. If you are considering this supplement, consult your healthcare provider to determine if a 1 mg dose of B12 is appropriate for your needs, especially given the potential risks associated with high calcium intake if this product contains calcium [NIH ODS].
