I have no idea what b6 does.
I just know that most seniors are low B12. B12 is made in cobalt rich soils. Grazing animals pull up grass contain it ( cobalamin) . Us seniors have less stomach acid. The B12 molecules gets separated and goes thru intestine wall into bloodstream. Seniors have less acid. Trouble is, most seniors have also damaged their 20 ft small intestine wall by drinking alcohol .
