MegaFood Vegan B12
Brand: MegaFood · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that MegaFood Vegan B12 is a straightforward supplement designed to address vitamin B12 needs. However, the data provided focuses primarily on calcium, not B12. For the specific ingredient calcium, the data supports its role in bone health, but we must be clear that this analysis is based on the calcium data available, not on B12-specific research [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. This mechanism is relevant if the product contains calcium, but for B12 specifically, data on mechanism is not available in the provided information.
Safety profile
Data not available for B12-specific adverse events from the provided FDA data. The total FDA adverse event reports across all supplements is 592,059, but this number is not specific to this product [FDA data]. For calcium, side effects at high intakes include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High calcium levels can also cause poor muscle tone and poor kidney function [NIH ODS].
Our recommendation
You should consult your healthcare provider before starting any supplement. The available data does not provide enough B12-specific evidence to make a confident recommendation for MegaFood Vegan B12. If you are considering this for B12, the data on calcium interactions is important to note: calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Always discuss potential interactions with your doctor.
