Julian Mitchell

Julian Mitchell joined Dr. John M. Torrens on The Total Entrepreneur for one episode on body.

What Julian talked about

Julian Mitchell discussed the functional mushroom industry, arguing that many mycelium-based supplements are diluted with starch or grain filler, and described a home iodine test that can reveal this by turning the powder black or purple-black when filler is present. He argued that liquid extracts offer greater bioavailability than powders or capsules, citing University of Queensland research he referenced showing increased potency and measurable neuronal outgrowth within 24 hours.

He went through specific mushrooms and compounds and the roles he attributes to each: lion's mane for REM sleep, focus, and neuroinflammation, cordyceps for sustained energy without a crash, and shilajit for hormonal support and nutrient transport. He also spoke about his own approach to sustaining high-intensity entrepreneurship, pointing to diet timing, time in nature, fasting, saunas, and ice baths as practices he uses, and argued that resilience is a trait shared by elite athletes and elite founders.
