Paul Stamets's Supplement Protocol: The Mycology Stack, Available at X-Optimum

Editorial forest-lab still of medicinal mushroom specimens, flask, and tea, no celebrity likeness

Paul Stamets is a mycologist, author of Mycelium Running and Fantastic Fungi adjacent public work, and founder of Fungi Perfecti / Host Defense. On The Joe Rogan Experience, in Host Defense materials, and in interviews, he has described a daily medicinal-mushroom protocol that is simpler than most longevity stacks and more species-specific.

This article is an educational cross-reference of publicly discussed compounds, not an endorsement, not a claim that Stamets uses X-Optimum, and not medical advice. Psilocybin remains a Schedule I substance in the United States. We cover the legal, catalog-overlapping species and the niacin mechanism he has described. We do not sell or recommend illegal compounds.

Search interest in a Paul Stamets supplement stack or Paul Stamets supplement protocol usually clusters around lion's mane, turkey tail, reishi, chaga, and the "Stamets Stack" idea (lion's mane + niacin, with psilocybin discussed only as research). Those are the biological jobs below.

1. Lion's Mane: NGF, hericenones, and erinacines

Stamets has said he takes lion's mane daily and has attributed late-life cognitive sharpness, in interviews, partly to that habit. The mechanism is not "mushroom energy." Hericium erinaceus contains hericenones (typically fruiting-body associated) and erinacines (typically mycelium associated). Both classes have been studied for stimulating nerve growth factor (NGF) synthesis. NGF maintains cholinergic neurons. That is hardware for attention and memory, not a stimulant buzz.

Hot-water extraction improves recovery of beta-glucans. Alcohol or dual extraction is more relevant if you care about the smaller terpenoids. A coffee that includes lion's mane is a delivery vehicle, not a replacement for a dedicated extract if cognitive output is the job.

At X-Optimum, map lion's mane to multi-species formulas rather than a single-species SKU:

Honest gap: X-Optimum does not currently list a standalone lion's mane isolate. Use the 10X / 6X formulas plus the coffee if you want Hericium in the mix.

2. Turkey Tail: PSK, PSP, and immune tone

Turkey tail (Trametes versicolor) is the species Stamets has discussed for immune surveillance, including PSK (krestin) and PSP, protein-bound beta-glucans studied in oncology-adjacent research. The useful claim for a healthy professional is more modest: beta-glucans engage pattern-recognition receptors (Dectin-1, CR3) on innate immune cells. That is a training signal, not a steroid for the immune system.

He has described turkey tail as a morning capsule in public stack roundups tied to Host Defense. Pair it with gut hardware if your limiter is barrier function rather than "immunity" as a vibe.

X-Optimum overlap:

Honest gap: no turkey-tail-only SKU.

3. Reishi: triterpenes and HPA downshift

Reishi (Ganoderma lucidum) is the evening-leaning mushroom in many of Stamets' public lists: AM and PM capsules in compiled routines, with triterpenes (ganoderic acids) as the non-beta-glucan story. Practically, people use reishi for sleep onset and stress load. Mechanistically you are looking at modest GABAergic and HPA effects in animal and small human data, plus polysaccharide immune signaling.

If cortisol magnitude is the limiter, a dedicated adaptogen is a cleaner tool than hoping reishi covers it.

X-Optimum overlap:

Stamets is not a sleep-strip spokesperson. The map is biological: if you are stacking reishi for downshift, you still need adenosine pressure, darkness, and a formula that actually hits GABA/theanine/magnesium pathways.

4. Chaga: melanin, betulinic acid, antioxidant load

Stamets and Host Defense materials treat chaga (Inonotus obliquus) as tea or capsule, often as a daily antioxidant and immune adjunct. Chaga is a sclerotium, not a classic mushroom cap. It concentrates melanin, polyphenols, and, when grown on birch, betulin-related compounds. The job is redox buffering and innate immune tone, not NGF.

X-Optimum has a dedicated SKU here:

Do not confuse this with removed birch-chaga truffle SKUs. Use the live chaga product handle only.

5. Niacin in the research stack (flush form)

The phrase Stamets Stack in public discussion is lion's mane + niacin, with psilocybin as a research concept he has patented around and discussed on Rogan. He has described niacin's peripheral flush as a way to "drive" compounds toward nerve endings. That is a hypothesis, not a completed human protocol you should copy with illegal drugs.

What you can do legally: use flush niacin only under clinician guidance (it hits lipids, glucose, and can be poorly tolerated), and treat lion's mane as the NGF layer. X-Optimum does not sell standalone niacin. B-vitamin coverage lives in:

We will not invent a niacin product. If lipids or flushing protocols are the goal, that is a physician conversation, not a cart add.

Psilocybin is omitted from the shopping list on purpose.

6. Vitamin D3 and omega-3 (support, not the mushroom story)

Compiled public routines also list vitamin D3 with fat in the morning and omega-3 with meals. Stamets is a mycologist first. These are standard foundation nutrients, not fungal IP.

X-Optimum does not currently list a standalone fish-oil or D3 isolate in the verified catalog used for this article. Use Optimized Multivitamin ($17.99) as the micronutrient floor, and food or a separate D3/omega product if labs say you are low.

Cross-reference table

Publicly discussed item Biological job X-Optimum product
Lion's mane NGF (hericenones/erinacines) Mushroom 10X, Fermented 6X, Lion's Mane + Chaga coffee, Brain & Focus
Turkey tail Beta-glucan / PSK-PSP immune tone Mushroom 10X, Fermented 6X, Super Probiotic
Reishi Triterpenes, downshift Mushroom 10X/6X, Ashwagandha complex, Sleep Formula
Chaga Redox / innate immune Optimized Chaga, mushroom coffee
Niacin (flush) Research stack, not a cart item Multivitamin B-complex only; no isolate
Vitamin D3 / omega-3 Foundation Multivitamin floor; no dedicated D3/omega SKU

How to run this without copying a brand you do not own

Stamets built Host Defense. X-Optimum is a different manufacturer. Match compounds and jobs, not bottles.

A practical weekday setup:

  1. Morning: mushroom coffee or 10X/6X capsules, plus multivitamin.
  2. If cognition is the limiter, add Brain & Focus, not a second coffee.
  3. If stress is the limiter, add ashwagandha/shilajit, not more reishi hoping it is KSM-66.
  4. If sleep is the limiter, Sleep Formula or Better Sleep Strips at night.
  5. Keep chaga in the stack if antioxidant/immune tone is the reason you wanted the tea.

Skip anything that requires a controlled substance. Skip invented doses. Titrate with a clinician if you have autoimmune disease, are on immunosuppressants, or have mushroom allergies.

Build Your Mycology Stack at X-Optimum

Stamets' public philosophy is species-level fungi as biological tools: NGF from lion's mane, innate immune training from turkey tail, triterpene downshift from reishi, sclerotial antioxidants from chaga. X-Optimum's catalog overlaps on multi-species mushroom formulas, dedicated chaga, lion's mane + chaga coffee, cognitive formulas, adaptogens, and sleep hardware.
