As B complex's go, that is a better dose than usual. However, if a person malabsorbs severely, it is barely enough to keep some of them afloat (assuming they aren't deficient and use and store efficiently). Not a safe bet.

Ironically, it's not nearly enough for many to make use of, and for all the rest it is way more than they need.

If you read my website (not a lot to read) you will see the answers to your questions, including why most medical people don't have good information.

Aside from the B12 issue, it is a good idea to take a B complex too because the B vitamins work closely together, and if you are low in any, others may not work as well as they should.
