Hello. I want to start using brewers yeast as supplement since it has amazing nutritional value. Brewers yeast earned a lot of attention for it’s high complete protein content up to 48%, vitamin B and mineral content. In particular it is interesting in my opinion for it’s high amounts of choline which is cognitive enhancer, as well niacin and other precursors for production of NAD+ - most promising antiaging compound and energizer. Taking them in tablet form is not worth it since doses are low. I want to order 25kg bag and plan to take 30 grams daily. But before that I want to know if there are any side effects of taking it at high doses everyday and what is it's shelf life. Read in one papper that it's better not to take more than 30g because not overdose on purines. Other than yeast was reported to be not so tasty so it would good idea to mix it into food such as soup.
