About
About Cap & Gill
Cap & Gill is an independent set of notes on ergothioneine, vitamin D2 and other mushroom nutrients.
About this address
From 2012 until early 2025 this address held the website of Entia Biosciences, a small company that worked on ergothioneine and vitamin D2. That website has gone. Cap & Gill is written by new, independent editors. It is not that company or its successor, it has no connection with the company, its people, its products or its shareholders, and it shows none of its logos, images or text. Nothing is sold here, there is no investor information, and nothing here is medical advice.
How the notes are written
Health statements are kept to what peer-reviewed papers and public nutrition bodies say, with the source next to each one. Where research is only in the lab, the notes say so.
Why every page ends with a Dutch energy guide
Mushrooms are cooked, kept cold and eaten through the dark months, and each of those steps runs on household energy. Each page follows that line from its own subject and closes with the full Dutch guide on energie vergelijken met cadeau from energievergelijkenmetcadeau.nl.
