  • Convenient single-serve packets
  • Smooth, non-chalky protein texture
  • Calmer, jitter-free energy
  • Broad, innovative product variety
  • Polarizing earthy mushroom taste
  • Occasionally weak coffee flavor
  • Gritty or clumpy powder mixing
  • Inconsistent perceived functional effects

Four Sigmatic earns mixed-to-positive reviews: many praise its instant coffees, cacao mixes, matcha, and plant-based protein for smooth texture, convenient single-serve packets, and calmer, jitter-free energy or improved focus, while others report weak flavor, gritty/clumpy mixing, and no noticeable functional effects. The brand is lauded for variety and quality ingredients but criticized for polarizing taste (earthy, mushroomy), inconsistent dissolution, and some blends feeling too sweet or bland.

  • I tried the Four Stigmatic Lions Mane Elixir. If you like warm and cozy drinks, then I think you'll like this. Abit earthy, but very comforting. A great pick me up without the caffeine jitters.

    Feedback

    Don't freak out about seeing the word mushroom. I promise you, there is no funky fungi taste in here. It's just a warm cozy cup of yum.

  • Convenient packaging and great customer service. I won't go through a pot of coffee, so I love that there are individual servings. Not a fan of all the flavors and still exploring all the products. I ordered the mocha fully expecting to love it, but I didn't even like it, I called and they credited me for the order. The chocolate and Defend and Think are my favs.

    The website could be a little better to navigate. Also, it's not easy to change your subscription. I have had to delete and recreate, which can be time consuming.

  • Four Sigmatic makes functional mushrooms and adaptogens delicious and easy to make part of my daily routine. My favourite? The Lions Mane Coffee. It gives me loads of energy in the morning and feels like a healthy alternative to coffee. I love mine straight up, or blended with MCT oil.

    Feedback

    I've purchased in the US and AU and have found it's much more affordable in the USA. I would love to see larger options available.

  • I tried the reishi hot chocolate. It was quite tasty.

    Feedback

    The pricing is very high. There are other options on the market that deliver the same thing for much more reasonable a price

  • I have been drinking Four Sigmatic's ground coffee with Lion's Mane for over 2 years now and absolutely love it! This coffee not only tastes great but also provides me with focus and a more balanced energy than regular coffee. Even my caffeine-sensitive boyfriend drinks it without getting the anxiety and jitters that he normally gets from coffee.

    Feedback

    Nothing! I have tried many of their products and have loved them all.

  • The “Focus Blend” powder by Four Sigmatic feels like the synapses in your brain are firing like crazy. I add it to my coffee every morning, and I find myself with sustained energy, sharpness, and boosted creativity. Anti-brain-fog.

  • Have had a variety of their coffee substitutes. Maybe they made me feel “better” but certainly not the same caffeine high as the ol’ brown standard. Taste was unique and would be nice in certain settings, but not something I’d want every day.

    Feedback

    Taste and usage occasion. Seems like a better substitute for afternoon tea as opposed to supplanting morning coffee.

  • I love the Mushroom cacao reishi powder. I add a little to my tea in the morning and it tastes so good! I drink it at night too. A nice healthy treat.

  • I’ve made the “hot chocolate” alternative and it was a good cozy drink but not quite the same as a real cup of hot chocolate.

    Feedback

    The mix didn’t dissolve very well into the hot water.

  • I had both the coffee and the mushroom tea, which both had Lion's Mane. It was amazing! My focus improved overall and I would definitely buy again.

  • These are really great! Been using them in my açaí smoothies and they work wonders!
