Your probiotic is making your gut worse.

You started it because the internet said gut health is everything. And it is. But the capsule you're taking contains Lactobacillus casei, Lactobacillus reuteri, or Streptococcus thermophilus — strains that produce histamine as a metabolic byproduct. For a woman with healthy histamine clearance, that's fine. For a woman whose DAO enzyme is already overwhelmed — from estrogen dominance, gut inflammation, or chronic stress — those strains are pouring gasoline on a fire she didn't know was burning.

More bloating. More brain fog. Skin reactions. Headaches after meals. She doubled the dose because she assumed die-off was happening. It wasn't die-off. It was histamine accumulating faster than her body could break it down — manufactured by the exact supplement she took to fix the problem.

You didn't choose the wrong brand. You chose the wrong strains for your current hormonal and histamine status.

Lactobacillus rhamnosus, Bifidobacterium infantis, Bifidobacterium longum — these are histamine-degrading strains that lower the load instead of adding to it. Check your label. If it's making you worse within two weeks, your gut isn't rejecting healing. It's rejecting histamine from a source it can't metabolize.
