Histamine intolerance can be worsened by probiotics - or helped.
It all depends on the probiotic strains used.
If you use probiotic strains which are known to increase or stimulate histamine, then your histamine intolerance will get worse.
If you use probiotic strains which are known to not produce histamine or to help modulate histamine release, then your histamine intolerance may improve.
