PureFormulas Vitamin B12 2000 mcg
Brand: PureFormulas · Form: LOZENGE [E0174] On Market
Our assessment
The evidence shows that this product provides 2000 mcg of vitamin B12 per serving. For most adults, this is a high dose that exceeds the daily recommended intake, but it is generally considered safe for addressing deficiencies or supporting energy metabolism [NIH ODS]. However, data for this specific ingredient is limited in the provided materials.
How it works
Think of vitamin B12 as a cellular energizer — it helps your body convert food into usable energy and supports the maintenance of your nerve cells and red blood cells [NIH ODS]. This high dose is often used by individuals with absorption issues or those following a strict vegan diet.
Safety profile
Data not available for this specific product. However, for the general category of vitamin B12, FDA has received 592,059 total adverse event reports across all supplements [FDA data]. High levels of vitamin B12 are generally considered safe, but very high intakes from supplements may cause mild side effects in some individuals [NIH ODS].
Our recommendation
Start with 2000 mcg daily if you have a confirmed deficiency or are at risk for low B12 levels. For general wellness, a lower dose may be sufficient. Always consult your healthcare provider before starting a high-dose supplement [NIH ODS].
