**Short answer:** Jo Calder is the pen name of the editor who runs Lion's Mane Mushroom UK. Jo is not a doctor, pharmacist or mycologist and does not give medical advice. Every page is written from the cited research, every health claim is graded, and mistakes are corrected openly.

## Why use a pen name?

The editor prefers to keep the site separate from their private life. A single, consistent pen name lets readers see that the same person stands behind every page and is answerable for it. We say so plainly here rather than inventing a biography.

## What does Jo do?

Jo decides what the site covers, reads the studies behind each page, writes and edits the articles, assigns the [evidence grades](/about/evidence-grades/) and handles corrections. Jo has no financial links to any company that sells lion's mane.

## Is Jo qualified to give medical advice?

No, and nothing on this site is medical advice. That is why each claim links to its source, so you can check it, and why we are looking for a qualified reviewer for the health pages. Research and drafting are helped by AI tools, and every figure is checked against its source before a page goes live.

## How can you contact Jo?

Email [hello@lionsmanemushroom.uk](mailto:hello@lionsmanemushroom.uk). If you think something is wrong, a link to the evidence helps us check it quickly.
