A lot of people carry gut irritation and leaky gut, and the thing that helps most is cheaper than anything in the supplement aisle.
The evening routine
Psyllium fiber dissolved in a large glass of warm water, about 30 minutes before bed. Start with one tablespoon. Some people work up to two. Some do none at all and are fine — this is a dial, not a prescription.
Two things to change first
If you use a creamer, use a full-fat one — whole milk or actual cream — rather than a dried powdered creamer. And no caffeine after 3pm.
None of this is dramatic. It is the kind of change that shows up over weeks in how your gut behaves overnight.
