Oh, we have done a lot of research on this and our conclusion is cyanocobalamin is the superior form.
There are studies that indicate that methylcobalamin is better absorbed than cyanocobalamin; however, methylcobalamin is not stable in food products over shelf-life and it’s also not permitted for use in food fortification in the EU because of its stability (it’s only permitted for use in supplements). Also, whilst methylcobalamin is more bioactive once it’s been absorbed, cyanocobalamin is absorbed by the body more readily.
Therefore cyanocobalamin is the most suitable choice. In addition we have added an amount of B12 that’s higher than the Nutrient Reference Value (NRV).
