Four Sigmatic vs BrewLune: The Two Most Transparent Labels Compared
In one line
Four Sigmatic vs BrewLune: BrewLune states three times the mushroom extract of Four Sigmatic Think per cup and tastes better, but Four Sigmatic is certified organic, publicly tested, available in ground and pods, and stocked in stores. Until BrewLune publishes a COA, Four Sigmatic remains the safer buy of the two.

The short version
These are the two labels on this site you can actually read. Four Sigmatic invented the category in 2012 and still prints its doses; BrewLune launched in 2025 and prints more of them. The difference is what surrounds the label: Four Sigmatic has certification, public testing, three formats and retail distribution. BrewLune has a better cup, a lower price and small direct-only batches.

Four Sigmatic
Four Sigmatic mushroom coffee (Think) is the most transparent mushroom coffee on the market: 250 mg lion's mane and 250 mg chaga fruiting-body extract, disclosed per cup, with 50 mg caffeine and third-party testing. The trade-off is price, at a premium $1.90 per serving for the instant packets, and only two mushrooms, with no cordyceps in the Think line.

Frequently asked questions
Which discloses more, Four Sigmatic or BrewLune?
Both print per-mushroom milligrams and fruiting body — the two clearest labels we cover. BrewLune adds minimum beta-glucan percentages per extract; Four Sigmatic adds a public third-party testing claim and organic certification. Call disclosure a draw and testing a Four Sigmatic win.
Which has more lion's mane?
BrewLune, with 500 mg per serving against Four Sigmatic Think's 250 mg. BrewLune also adds 400 mg cordyceps and 300 mg reishi that Four Sigmatic's Think line doesn't include. Neither approaches the 3 g per day used in the main cognition trial.
Which tastes better?
BrewLune, in our tasting — a cleaner medium-roast flavour with no chaga note. Four Sigmatic is a close second among instants and is the better-tasting of the two if you want real ground coffee, since BrewLune only sells instant.
Which is cheaper?
BrewLune at $1.13 per cup versus $1.90 for Four Sigmatic's instant packets. Four Sigmatic's 12 oz ground bag is cheaper per cup than its packets and closes most of the gap if you brew at home.
