Does anyone here use brewers yeast as a natural source of B vitamins? If so have you had any reactions particularly if trying gluten-free?
I took it for a while once and it could have been placebo effect but I did start to feel more energetic, but stopped taking as this was around the time my immune system went haywire with urticaria. I take synthetic methylated B vits already, but keep hearing natural sources if vits are better absorbed.
