Natural Factors B12 Methylcobalamin 1000 mcg
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that this product provides 1000 mcg of methylcobalamin, a form of vitamin B12. However, the data provided is for calcium, not vitamin B12. Because of this mismatch, we cannot offer a specific assessment of the Natural Factors B12 Methylcobalamin 1000 mcg supplement based on the data you have supplied. Data not available.
How it works
Data not available to explain how this specific product works. The data provided describes calcium's mechanism, which includes bone mineralization and neuromuscular relaxation [NIH ODS]. This information does not apply to the B12 supplement you are asking about.
Safety profile
Data not available for the safety profile of this B12 product. The total number of adverse event reports in the FDA system is 592,059 [FDA data], but these reports cover all supplements and medications, not this specific product. The calcium data mentions side effects like constipation, nausea, and abnormal heart rhythms at high levels [NIH ODS], but this information is not relevant to methylcobalamin.
Our recommendation
Data not available to make a recommendation for this specific product. To get a reliable assessment, you would need to provide data specifically for vitamin B12 (methylcobalamin) from sources like the NIH Office of Dietary Supplements (ODS) or the FDA. Without that information, we cannot offer guidance on dosage, benefits, or risks.
