View Full Version : B12 in Nelumbo nucifera ("Sacred Lotus")?

This (https://umwelthygiene-tierhygiene.uni-hohenheim.de/fileadmin/einrichtungen/umwelthygiene-tierhygiene/April_2009/Abschlussarbeiten/Dissertation_Tepsorn.pdf) document from Universitšt Hohenheim (https://www.uni-hohenheim.de/) in Germany mentions that Nelumbo nucifera Gaertn. rhizome is [...] "rich in Vitamin B12, rare among vegetables". Many of the 50-100 references we have listed mention that B12 is rare in plants - several of them claim that the plant they mention more or less is the only one that contains B12. They should visit this subforum more often. :)

I'm always a little skeptical when someone mentions nutrient levels (B12 in particular) without references to the actual studies they have this information from. I still post links to these articles here - maybe these threads can serve as background material for researchers who have the budgets and labs it takes to find the detailed B12 level for specific plants, incluidng the active/inactive analogue ratio? Hopefully they'll perform the tests on fresh, organic plants, so the results aren't distorted by the expected B12 decrease derived from non-organic farming, exposure to light, ageing, exposure (before B12 is measured) to chlorinated water, heat and so forth.
