Mushroom Coffee Review
The brand that made mushroom coffee mainstream. Five years later, is the original still the best — or have upstarts like Ryze and Everyday Dose overtaken it?
Four Sigmatic remains excellent — the Think Coffee instant packets are the easiest entry into mushroom coffee, and the ground coffee offers real value. Not the best value per mushroom dose, but the most accessible and widely available.
Four Sigmatic was founded in Finland in 2012 by Tero Isokauppila, who grew up harvesting wild mushrooms and had a background in food science. The brand launched in the US in 2015 and was the first to popularise mushroom coffee as a mainstream wellness product.
Before Four Sigmatic, functional mushrooms were confined to supplements and traditional medicine. The brand made the concept accessible by blending mushroom extracts into instant coffee packets — a format people already understood. Every competitor (Ryze, Everyday Dose, MUD\WTR) exists partly because Four Sigmatic proved the market.
The instant Think Coffee packets taste like lightly earthy, medium-bodied instant coffee. The mushroom flavour is present but subtle — less pronounced than Ryze's powder, which is more earthy and oat-like.
The ground coffee bags taste closest to regular coffee — the mushroom note is barely detectable, which makes it the easiest transition for people sceptical of functional coffee.

| Brand | Price | Mushroom dose | Best for |
|---|---|---|---|

| Ryze | ~$30/bag | 6 types, higher dose | Value, mushroom variety |

| MUD\WTR | ~$40/bag | 4 types | Coffee replacement, ayurvedic herbs |
It depends what you want. Four Sigmatic offers more product variety — instant single-serve packets, ground coffee bags, and cacao blends — and is widely available on Amazon. Ryze has more mushroom types per serving (6 vs 2) and is better value per serving. For convenience and variety, Four Sigmatic. For mushroom density and value, Ryze.
Lion's Mane mushroom has the strongest research support of any functional mushroom for cognitive performance — it promotes nerve growth factor (NGF) production. Four Sigmatic's Think blend contains a meaningful 250mg dose of Lion's Mane extract. Most users report subtle improvements in focus and mental clarity, not a dramatic stimulant effect.
Four Sigmatic is widely available on Amazon, at Whole Foods, Target, and directly from foursigmatic.com. Amazon typically has the best prices on multi-packs. The single-serve instant packets are the easiest entry point.
