1 Why is butyrate often described as the “currency” of gut health?
- It directly comes from food like vitamins and minerals
- It replaces calories as the body’s main energy source
- It rewards gut bacteria by protecting the gut lining
Butyrate is made when microbes ferment fiber and, in return, fuels and protects the gut lining, strengthening the entire digestive system. Learn more.
- It reduces the need for dietary fiber once produced
2 What is butyrate and how is it formed in your body?
- A short-chain fatty acid (SCFA) created when gut bacteria ferment dietary fiber
Butyrate is an SCFA produced by your gut bacteria as they break down dietary fiber. Learn more.
- It is a long-chain fatty acid produced as the pancreas digests protein-rich foods
- A sugar created by the liver during fasting and low-carb diets
- It is an essential amino acid supplied directly by eating animal protein
3 What unintended effect does a typical ketogenic diet have on colonic butyrate production?
- It triggers the body to make more butyrate through fasting and ketosis alone
- It raises butyrate output by boosting healthy fats and protein in the gut
- It makes no noticeable difference to butyrate, leaving gut health unchanged long term
- It lowers butyrate levels by reducing fiber and butyrate-producing gut bacteria
Cutting out fiber on a ketogenic diet lowers colonic butyrate, since the gut bacteria that make butyrate rely on fiber as fuel. Learn more.
4 Which cellular process is most directly supported by urolithin A supplementation?
