Fourteen symptom-guided supplement tracks for gut health, each with a typical range, what the published evidence actually shows, and Dr. Mike Hauman's clinical experience side by side. Includes a four-week start-low-and-slow sequence, safety screens, and the red flags that mean you need a clinician rather than another supplement.
Most supplement guides tell you what to take. This one also tells you how well it has been tested.
Fourteen tracks, matched to the pattern you actually have — loose stool, slow motility, cramping, bloating, barrier irritation, meal-related discomfort. Each track carries a goal, a common product, a typical range, and two separate columns that are worth reading against each other.
Published evidence
What has been formally tested, in whom, at what dose. Where the research is strong, it says so. Where it is limited, preliminary, or mixed, it says that too. Peppermint oil has a meta-analysis of ten trials behind it. Omega-3 has two large trials that came back negative for gut outcomes. Both facts are in the table.
Clinical experience
What I observe in practice, labeled separately so you always know which one you are reading. Research lags practice, and one formulation is not another — where the direct evidence is limited, this document says so rather than implying more certainty than exists.
Selected sources
Every effect size in the table is cited, so you can check the work rather than take my word for it.
A four-week start-low-and-slow sequence
Fix the basics, then add one thing at a time with a defined review date. Week one is a symptom log, not a purchase.
Safety screens and product-matching notes
Which cautions apply before starting anything, what to look for on a label, and the specific labeling trap where a magnesium product listing 400 mg delivers more elemental magnesium than the supplemental upper limit.
When to stop and see a clinician
Bleeding, black stool, persistent fever, progressive weight loss, repeated vomiting, nighttime symptoms. Some patterns are not a supplement problem, and the guide names them plainly.
