The Gut Health Guide
The Stretch Board targets the root cause by rebuilding the strength and flexibility your feet have lost.
How your gut actually works, and why it goes wrong at both ends.
Most gut advice starts at what to eat. This starts one step earlier, at what your colon is actually doing all day. Once that part makes sense, the advice stops being a list of rules to remember and starts being obvious.
A 12 page guide in plain English. No jargon, no diagnosis, no scare stories.
What is inside
- Your colon has one job, and why how long things take decides everything
- Why constipation and diarrhea are the same machine at the wrong speed, not two conditions
- What actually sets that speed
- Soluble and insoluble fiber, and why the difference decides whether it helps
- Why fixing one end so often throws you to the other
- Five habits that cost nothing: water, consistency, chewing, walking, sleep
- Why fiber without enough water does not work
- What the first two weeks feel like, and how to climb slowly enough to stick with it
Delivered as a PDF you can read on a phone, a tablet or a laptop, or print out and leave on the counter.
Pairs with 12 Ways To Take It, the recipe book, which is the practical half.
General information about how digestion works. It is not medical advice, and it is not a claim that any product diagnoses, treats or cures any condition. If something is new, severe, or does not settle, that is a conversation for your doctor.

3 Problems. 1 Insole.
Most insoles only fix one thing. That's why they don't work.
After 45, your feet need all three: arch support to stop collapse, cushioning to replace what you've lost, and massage points to boost circulation so your feet can actually heal.
Thriv delivers all three — in every step.

Slip In. Walk Out. Done.
Trim to fit. Slip them in. That's it. No special shoes, no complicated setup — just real support in the shoes you already wear.
