⚠️ Regulatory Compliance Notice

Our Mesima extract is no longer available for human consumption under UK Novel Food regulations.

We know this news is frustrating - Mesima has been a core part of so many wellness journeys, and removing it was not a choice we made lightly. While its safety and quality remain exactly the same, the current UK classification restricts its sale for human use.

We’re closely monitoring the situation and remain in ongoing discussions about future review of the Novel Food status for Mesima and other mushroom extracts that matter deeply to our community.

Rest assured, we have put together some great alternative options for you, which you can see below.

Really helped with bloating

I didn’t expect it but after a month I felt less puffy and more comfortable in my body. Premium packaging too.

Great detox support

I noticed after 2 weeks I wasn’t as sluggish after meals. My body feels like it’s clearing things out better.
