About our writers

Shumi's journal is written by our own team. We work hands-on with functional mushroom sourcing, extraction and testing, and we write about it in plain, evidence-informed language. We are specialists and enthusiasts in functional mushroom extracts, not medical professionals, so our articles are for general information and are not medical advice.

Hannes Unt

Founder, Shumi Biotech. Hannes founded Shumi and leads on sourcing and extraction quality. He works directly with the fruiting-body material and the ultrasonic dual-extraction process behind every Shumi extract, and writes about the practical side of functional mushrooms.

Jens Pold

Collin Srivaratonbul

Writer, Shumi Biotech. Collin writes for Shumi on functional mushrooms and everyday wellbeing, aiming for clear, honest explanations of what these extracts are and are not.

Accuracy and review

We cite peer-reviewed research where we can and aim to represent the evidence honestly, including its limits. Our articles are for general information, not medical advice; where an article has been reviewed by a qualified professional, that is noted on the article itself. If you have a health condition, are pregnant or breastfeeding, or take medication, speak to a healthcare professional before starting any new supplement.
