Evidence
B
HONEST CORRECTION: the common vegan claim that tempeh supplies B12 does not hold up. Any B12 present comes from contaminating bacteria, not the Rhizopus culture, and is not a reliable source.
Study dose vs. serving
A modest plant source of vitamin K2 (menaquinones); natto is far richer in MK-7.
Sato T, Schurgers LJ, Uenishi K. Nutr J. 2012;11:93. PMC3502319 (MK-7 bioavailability). B12 assessment per VeganHealth review of Areekul et al. / Albert et al.
Use caution if
