I just ordered some off of amazon and it's "NOW" brand @Miss Lydia, correct me if I'm wrong, but it should be "fortified" right? I think that is the whole point. I just got 10lbs of it too and I've been putting it in soup, popcorn and everyday in the duck bucket food.I order off Amazon but if you want go to TSC and pick up liquid BComplex and start her on it. It’s like liquid gold for waterfowl that are having leg problems. It’s in the cattle dept. it will say injectable but just peel off the foil use a dropper pull out a couple ml and put it over something yummy. Then you can order the Nutritional yeast it’s not Nutritional brewers yeast I buy NOW brand because I can get it in bulk.
I'd still get the liquid B-complex first and start that right away. I think it's a miracle supplement.
