It says liquid B is it B complex? how much niacin is in it? I don't know how much is in that bottle but you will need to have her on this until she is fully recovered which may mean you'll have to buy more. 1 ml is the dose per day. You can use human B complex you'll just need to crush the pill I take b complex and it comes in capsule form which would mean all you'd have to do is open the capsule and put it over feed or treat. It's labeled for birds so it should be fine to use [the bottle you posted about]
