Psyllium Husk Fiber
GI normalizer for GLP-1 users, handles constipation and stabilizes blood sugar.
What it is
Soluble fiber from psyllium plant. Forms a gel in the gut. Slows nutrient absorption (good for glucose stability) and adds bulk to stool (handles GLP-1-induced constipation).
Why peptide users take it
GLP-1s slow gastric emptying, which combined with reduced food (and water) intake makes constipation almost universal. Users report 70%+ improvement on psyllium within a week.

How it actually works
Psyllium is a soluble fiber that absorbs water and forms a gel. In the gut that gel does three things: pulls water into the stool (softens it), bulks it up (triggers normal motility), and slows nutrient release (smoother glucose curve). It's also a prebiotic, the gut bacteria ferment some of it, producing short-chain fatty acids that feed the colon lining.
Dose
When to take
Signs you actually need this
- BMs less frequent than every other day
- Hard, pellet-like stools
- Bloating that doesn't resolve from gas-x or movement
- Hemorrhoid flare-ups from straining
Signs it's working
- Daily BM within 7–10 days of starting
- Stools become softer, easier to pass
- Bloating reduces (week 2+, after the gut adapts)
- Steadier post-meal energy (the glucose-smoothing effect)
Common mistakes
- Taking it dry or under-hydrated, risk of esophageal blockage
- Starting at full dose and getting blasted with gas, ramp from 1 tsp to 1 tbsp over a week
- Taking it at the same time as oral meds, psyllium reduces absorption of many drugs (thyroid, antibiotics, etc.)
- Buying flavored sweet versions while on a GLP-1, sweet taste can trigger nausea
Where to buy

Caveats
- Always with water. Dry fiber can cause esophageal blockage.
- Start at half-dose for a week; sudden fiber load can cause gas.
- Take 2+ hours apart from oral medications, psyllium can reduce absorption.
