The limits are published alongside the reasoning.
- Evidence tiers
Every article carries an explicit evidence tier, so established biology is never presented as if it were clinical proof.
Read the claim ledger - What this does not prove
Mechanistic pieces are required to state their own limits and the competing explanations that would fit the same data.
See the counterarguments - Published corrections
Where the reasoning has been revised, the revision is recorded rather than quietly edited away.
Review the standards
Pick the sentence that sounds like your situation.
- Why does my SIBO keep coming back?
- Are SIBO breath tests actually reliable?
- Why don't antihistamines settle my symptoms?
- Can I have mast cell activation with normal tryptase?
- Why won't my Long COVID symptoms resolve?
- Why did COVID trigger this in me and not others?
- Why are my labs normal when I feel terrible?
- Why doesn't my stool test match my symptoms?
- Why does every protocol stop working after two weeks?
- Why did butyrate or probiotics make me worse?
- What do bile acids have to do with my gut symptoms?
- Can gut health affect my hormones and egg quality?

The Gut–Catecholamine Connection in POTS: How HPHPA May Disrupt Norepinephrine, Vascular Tone, and Methylation
A mechanistic reading of why a microbial aromatic metabolite (HPHPA) may sit upstream of catecholamine handling, vascular tone and methylation load in POTS and dysautonomia. Hypothesis-generating, anchored in organic-acid and microbiome patterns seen in complex cases.

The Microbial Metabolites That May Be Rewiring the Brain: The Hidden Link Between SIBO, IBS, MCAS, Autism, ADHD, Glutamate, and Catecholamine Dysfunction
HPHPA, hydrogen sulfide, D-lactate and ammonia are microbial metabolites that may pressure catecholamine regulation through dopamine β-hydroxylase, COMT and mitochondrial ATP. A case-anchored look at the hidden link between SIBO, IBS, MCAS, POTS, ADHD-like symptoms and autism-spectrum features — a metabolite-driven mechanism rather than a purely compositional dysbiosis.

What a Two-Decade Steroid-Dependent IBD Case Revealed About Redox Collapse, Malabsorption, Microbial Instability, and Host Capacity
A man in his forties with two decades of steroid-dependent inflammatory bowel disease was taking four grams of vitamin C daily — and his ascorbate marker sat near the bottom of the range. That contradiction opened a full mechanistic case analysis of redox collapse, fat malabsorption, microbial instability, and host capacity.

The Gut Is Wiring the Brain: The Biomarker Pattern I Keep Finding in Autism and ADHD
Over the last several years, while reviewing complex pediatric cases involving autism spectrum disorder, ADHD, developmental regression, sensory dysfunction, hyperactivity, and mixed neurodevelopmental presentations, I have repeatedly observed a similar biological pattern emer…
