§ Published milligrams

Every ingredient. Every milligram. Every citation.

Most mushroom-coffee brands hide dosages behind "proprietary blends." We publish every number. If the math doesn't work, you'll see it before you spend a dollar.

Below: the six functional ingredients in one serving, the research behind each, and an honest read on where our dose sits relative to clinical trials. No disease claims. No overclaims.


Lion's mane

1,000 mg
Hericium erinaceus · 100% fruiting body · 8:1 dual-extract · ≥25% β-glucans

The focus workhorse. Lion's mane has the largest clinical-research base of any functional mushroom in the cognitive-function space. The most-cited trial (Mori 2009, Japan) used 3 g/day over 16 weeks in older adults with mild cognitive impairment — their scores improved significantly and declined again after stopping.

We dose 1 g per serving. That sits at the upper end of common consumer products (most competitors use 500 mg) but is below the Mori clinical-trial dose. That's an honest trade-off: one cup per day is the product promise. Multi-gram daily dosing would mean three cups, which isn't the format.

Research: Mori et al. 2009, Phytotherapy ResearchPubMed 18844328. Acute healthy-adult trial: Docherty et al. 2025 — PMC12018234. Alzheimer's Drug Discovery Foundation rating: "promising, not yet definitive."

Cordyceps militaris

750 mg
100% fruiting body · 10:1 extract

Cordyceps is the mushroom most associated with athletic performance and exercise tolerance. Hirsch et al. 2017 saw VO₂ max improve +4.8 ml·kg⁻¹·min⁻¹ after 3 weeks of a mushroom blend containing cordyceps. The blend was dosed at 4 g/day. Our 750 mg is below that.

We include it because the cordyceps-and-focus folk-wisdom predates the athletic literature — it's the ingredient people who "need a cup to get going" tend to notice first. Fruiting-body-only (never mycelium-on-grain) per the Nammex methodology.

Reishi

500 mg
Ganoderma lucidum · 100% fruiting body · 10:1 extract · ≥25% β-glucans

Reishi is the balance ingredient. Mechanistic studies (Yao et al. 2021, Scientific Reports) show a sleep-promoting effect through gut-microbiota and serotonin pathways in mice. Human trials are smaller pilots at 6 g/day. Our 500 mg is a fraction of trial doses — we include it for traditional balance, not as a sleep claim.

L-theanine

200 mg
Green-tea-derived amino acid · pharmaceutical-grade

The non-mushroom anchor of Solin, and the one with the most directly-applicable research. Haskell et al. 2008 (Biological Psychology) showed that 250 mg L-theanine + 150 mg caffeine improved attention and reaction time beyond caffeine alone. Our 200 mg sits near that trial dose, paired with ~90 mg caffeine — the L-theanine-to-caffeine ratio matches the published synergy direction while keeping absolute caffeine low.

Research: Haskell et al. 2008 — PubMed 18006208. Follow-up: Kahathuduwa et al. — PMC4480845.

Caffeine

~90 mg
Green tea + coffee fruit · natural sources only

Roughly equivalent to a single drip-coffee serving. Deliberately under-dosed relative to most energy drinks or Keurig pods. The L-theanine pairing is what gives the focus without the jitters; dumping more caffeine into the blend would undermine the no-crash positioning.

Cacao + MCT powder

taste + mouthfeel
Functional vehicle · not active

Natural cacao for flavor. MCT powder for mouthfeel and as a fat vehicle for extract absorption. No sweeteners, no stevia, no artificial flavors.
