These extracts could explain why some with candida are sensitive to some types of foods/supplements that are sulphur derived. Perhaps certain types of sulphur accelerate growth rate/metabolism of yeast.
Its interesting that yeast flakes/brewers yeast are high in sulphur. Seems like sulphur is highly utilized by yeast for growth. Maybe certain strains of yeast utilize sulphur more than other types of yeast strains...?
