B15 (pangamic acid) WHAT IS VITAMIN B15 PANGAMIC ACID? Pangamic acid or pangamate is often referred to as vitamin B15, though it isn’t officially recognized as a vitamin because it does not meet the qualifications for one and no deficiency profile has been established. Originally, the name pangamic acid was used to reference a substance called “D-gluconodimethyl aminoacetic acid”, which is naturally present in apricot kernel seeds, sesame seeds, pumpkin seeds, brewer's yeast, and brown rice.
