Essential cofactor measured as total vitamin B-12, summing the cobalamin vitamers found in food — chiefly adenosylcobalamin and hydroxocobalamin, with methylcobalamin a minor contributor. Required by methionine synthase and methylmalonyl-CoA mutase. Food panels report the total; supplements name the specific vitamer they contain.
Panel measurand rather than a single administered substance. Added when nutrient rows that reported this measurement were found filed under the slug of one specific species.
