Our Story
The mushroom has always been the Teacher.
I just had to become quiet enough to listen.”
Craig Fourie
Founder & Director
32 years of experience.
Many fungal species.
I have been growing all types of mushrooms for 33 years. Long before it was a wellness trend, and certainly before anyone in South Africa was talking about beta-glucans and dual-phase extractions. I grew them because they fascinated me. Organisms that exist at the boundary between kingdoms - between what feeds us and what heals us.
My background is not what you would expect from a mushroom farmer. I trained as a Tool, Jig and Die Maker - precision engineering, CNC metrology, CAD/CAM. I spent seventeen years in the motor industry building things to tolerances measured in microns. That training came in super handy for building Mushroom Guru!
When I turned my full attention to Ganoderma sichuanense thirteen years ago, I brought an engineer's mind to a biological problem. I had to measure and validate everything. I had to trust the data, and question the tradition.
The same precision that put parts into engines and production lines is what put six independent laboratories behind a single extract.
Built over three decades.
Verified over thirteen years.
In 2021 we were accepted into the SAVANT innovation cohort. This was one of South Africa's most selective programmes for science-led businesses. In 2022, with SEDA support, we completed the technology transfer that brought our full dual-phase extraction capability in-house to our Strand facility. In 2025, Inqaba Biotechnical confirmed our source culture as Ganoderma sichuanense Zhao & Zhang by dual-marker genomic sequencing — ITS 99.69%, EF1-alpha 100% - first thought to be Ganoderma lucidum.
Every claim we make about MG-LZ8™ is traceable to an original laboratory document. No marketing language without evidence behind it.
Not more of the same.
Something different entirely.
Most Reishi products on the market are ground fruiting body powder - dried mushroom, milled fine, put in a capsule. The beta-glucan content is modest. The triterpenoid content is marginal. The bioavailability is limited, to say the least.
Antler morphology was the first breakthrough. Ganoderma sichuanense, cultivated under elevated CO ², grows in branched antler formations rather than the flat conk it forms in open air. HPLC analysis confirmed a 12× compound concentration advantage over standard conk morphology. The antlers concentrate the very active ingredients that matter most.
Dual-phase extraction was the second breakthrough - a sequential ethanolic and aqueous cascade that captures both the fat-soluble triterpenoids and the water-soluble polysaccharide beta-glucan fraction in a single process. The result is MG-LZ8™. 348× the potency of standard Reishi powder. Not claimed. Documented. Next is the third high-heat phase to capture more glucans - the upgrade from MG-LZ8 to FS-19.
A single 15mg dose delivers the molecular density equivalent of 5,400mg of standard Reishi powder. The engineer in me needed to know that number was real before I would put it on a label.
None of this exists
without Nikki.
I can build systems. I can optimise processes. I can read a chromatogram and tell you what it means. But running a business and the operations, the relationships, the daily discipline that turns a passion into something real, well, that is Nikki's domain.
We have been married for 19 years. We have been in business together for 14. And we are still in love. "In business and in Love".
Nikki is our Operations Director in title. In practice she is the reason Mushroom Guru functions. Nikki is the reason orders go out on time, the reason why stockists trust us, the reason the facility in Strand runs the way it does. Behind every product that leaves our door is Nikki's quiet insistence on doing it properly. Processed and packed with LOVE.
I get to do the science. Nikki makes sure the science becomes something people can hold in their hands.

Not a supplement company.
A cultivation and research facility
that also makes products. A BioTech company in development.
The distinction matters. Everything we sell is built on what we grow, extract, and verify ourselves. We do not use outsourced raw material, and we do use borrowed science.
For Consumers
The science is on this page and every document saved
Every claim about MG-LZ8™ traces to an original laboratory document. Six independent institutions. Thirteen years of documentation. Please take the time to read it.
