I've been reading about hamsters having yeast for B12 added to their diet, about once a week.
To help with stress and fur loss associated with it.
I was curious if my nutritional yeast flakes, this brand I use in my meals.

Would be appropriate, it says the only ingredient is dry inactive yeast.
It doesn't taste bitter really, I use it as a substitute for cheese mostly and hamsters do like that flavour.
