Four Sigmatic vs Om Mushrooms: Which Is Actually Worth Buying?
Two of the most recognized mushroom supplement brands go head to head. We compare the ingredients, the dosing, and the price so you don't have to.
Two brands come up constantly in mushroom supplement conversations: Four Sigmatic and Om Mushrooms. Both are wildly popular. Both have strong branding. And both get recommended constantly — often by people who've never actually compared their labels side by side.
We did. Here's the honest breakdown.
🏆 The Short Answer
Om Mushrooms wins on ingredient quality and value. Four Sigmatic wins on taste and convenience. Which is right for you depends entirely on what you're optimizing for — and we'll walk you through exactly that.
Who Are These Brands?
Four Sigmatic launched in 2012 out of Finland, built around the idea of making medicinal mushrooms accessible by blending them into coffee and hot cocoa mixes. They grew fast on the back of influencer marketing, sleek packaging, and a genuinely good product concept. Today they're probably the most recognizable mushroom brand in the world.
Om Mushrooms launched in 2014 in California with a more science-first approach. They grow their mushrooms in-house in climate-controlled facilities, use the full mushroom (fruiting body plus mycelium), and publish more detailed product specs than most brands in the space. Less Instagram-famous, more quietly respected.
⚠️ What To Watch Out For
Many mushroom coffee blends — including some from both brands — contain much less actual mushroom than you'd expect. A 250mg dose of lion's mane extract in a coffee blend is not the same as 1,000mg in a dedicated supplement. Keep this in mind when comparing products across categories.

Four Sigmatic — What We Actually Think
Think Coffee with Lion's Mane & Chaga
Let's give Four Sigmatic credit where it's due: they made functional mushrooms mainstream. Their mushroom coffee products are genuinely good — well-formulated, great tasting, and easy to build into a daily routine. If you're a coffee drinker, that's a real advantage.
The issue is dosing. Their flagship Think coffee contains 250mg of lion's mane and 250mg of chaga per serving. That's a reasonable amount for a daily maintenance dose, but it's well below the 750mg–1,000mg used in most cognitive studies. You're getting real mushroom benefit — just not a therapeutic amount.
Their transparency on sourcing and beta-glucan content has also been inconsistent. When you're spending $15+ for 10 servings, you should know exactly what you're getting.
Om Mushrooms — What We Actually Think
Lion's Mane Organic Mushroom Capsules
Om wins this comparison on the fundamentals. They grow their mushrooms in certified organic conditions in Carlsbad, California. They use the full mushroom — fruiting body and mycelium — and they're transparent about what's in each capsule. Their lion's mane capsules deliver 667mg per serving, which you can stack to hit 1,000mg+ if you're serious about results.
The price is also significantly better. At roughly $0.28 per capsule, you can take a meaningful dose every day without doing math on your supplement budget. That consistency is what actually produces results — not one heroic dose a week because the product is too expensive to take properly.
The downside is obvious: it's a capsule, not a coffee. If you need your supplements to taste like something, Om isn't going to excite you. But if you want the best mushroom per dollar you can reliably put in your body, Om is the answer.
Can You Use Both?
Yes — and honestly, this is what we'd do. Start your morning with Four Sigmatic coffee for the ritual and the taste. Take two Om capsules alongside it for the actual therapeutic dose. You get the experience of Four Sigmatic and the efficacy of Om for about $2 a day combined.
It's not the cheapest approach, but it's probably the most enjoyable way to hit a meaningful daily dose consistently.
The Bottom Line
If you're choosing one: Om Mushrooms. Better ingredients, better dosing, better value, and more transparency about what's in the bottle. Four Sigmatic is a great product if you're a coffee person who wants something over nothing — but it's not where you'd go if results are the priority.
If you're new to mushroom supplements and just want to start somewhere, either works. Just don't confuse great branding with great formulation. Those are two different things.
