If you’re tired of sleepless nights, Four Sigmatic says they can help. They’re not messing around this 3-ingredient combo. They’ve included 1500mg of Reishi, Tulsi, and Field mint and Rose Hip extracts in their Four Sigmatic Reishi Elixir Mix. All of their ingredients are USDA-certified organic and tested for potency. The Reishi powder is extracted from fruiting bodies that are grown on linden logs. This is important since the medicinal benefits are found in this fruiting body, not the mycelium. Some mushroom products use both, which is not nearly as potent as the fruiting body extract. But Four Sigmatics knows better. 

Reishi, an immunomodulating adaptogen, is known as a sleep and stress ally. With 1500mg of Reishi in one serving, this elixir contains a therapeutic amount to produce results. But, it won’t taste like a hot chocolate or latte. If I had to add a score for taste, it wouldn’t be very high. FS describes this elixir as “bitter,” which won’t appeal to everyone. Swap out your usual nightcap for this concentrated elixir to get a better night’s sleep.  – Kelsey Lorencz, RDN

WHAT IS THIS Four Sigmatic Reishi Elixir Mix?

This is a superfood beverage infused with Reishi, a medicinal mushroom and adaptogen. As well as a handful of other botanicals and plant extracts all to help you get a better night’s sleep. Four Sigmatic recommends mixing this with some hot water, nut milk, or milk alternative before bed. We’re pretty sure the FDA has not confirmed that these extracts and adaptogens will help you sleep. But there has been centuries of anecdotal evidence from Chinese and Eastern European cultures.

Does this Use Fruiting Bodies or Mycelium? 

This is all about those fruiting bodies. Four Sigmatic uses the fruiting bodies of any medicinal mushrooms they infuse into their products. The fruiting body is the part of the mushroom you see. The cap, if you will. (Will you?) Some brands use the mycelium, which is the root. It’s cheaper because it has less of the antioxidants and adaptogens that are in the fruiting part of the mushroom. Anytime you ever consider purchasing a mushroom-infused product, always make sure it uses the fruiting body. And then you get to quote Mrs. Doubtfire and yell, “It was a run-by fruiting!” to anyone who will listen. Sidenote: we will always listen.

There’s 1500mgs of the Reishi mushroom in one of these packets. Which is a nice little amount. Not a ton, but a nice amount.

WILL THIS Four Sigmatic Reishi Elixir Mix GET YOU HIGH?

No! These are regular mushrooms like you would buy at the grocery store. These aren’t the magic mushrooms.


Try just drinking one of these at first. Then see how you feel. If it helps you sleep then awesome. Keep drinking one for a while to see how it works into your system. Then take it from there. It’s all up to you at the end of the day. But we do recommend taking it easy at first just in case you are extra sensitive to Reishi or rose hip or any of the other plant extracts.

Plant extract and botanical elixirs like these can vary in how they effect someone. We all know that everyone is different. So some people may take a few sips of this elixir and immediately feel the effects. Others may not. We do always recommend trying just one

Yes it is! It kind of bums us out that we even have to bring this up. But since medicinal mushrooms sometimes get confused with “magic mushrooms” we feel the need to clarify that THESE ARE NOT MAGIC MUSHROOMS. Sorry for yelling, but we just want to make sure everyone’s on the same page.

IS THIS Four Sigmatic Reishi Elixir Mix TESTED AND CERTIFIED?

It’s probably pretty obvious already, but yes. Our good friends at Four Sigmatic tests all their products. (If we’re being honest, we’re technically not “good friends” with anyone at FS. We wouldn’t mind being friends with them. But they have yet to return any of our emails.) In fact, they even wrote half a book about it on their site.
