Chaga Ingredients

DEFEND

Defend with Chaga

We know now more than ever how important your immune system is for overall health. Getting enough sleep, reducing stress, and eating healthy all contribute to a strong immune system. Once you have that strong foundation, a daily functional mushroom routine can help to defend your immune system. 

Chaga (Inonotus obliquussupports immune function, and has been used for hundreds of years. Chaga mushroom has beta-glucans, polyphenols, polysaccharides, and antioxidant properties that all support your immune system

We recommend starting your day with the King of Mushrooms, because with everything you have going on, there’s no time for a timeout. It’s your daily bodyguard to keep you well. Try a 1-month routine of either Chaga Elixir or Mushroom Ground Coffee, or both for double immune system support. We guarantee you won’t look back. If you do, we’ll give you your money back!

Founder of Four Sigmatic - Tero

MEET TERO

Whose idea was this?

Meet our founder, Tero. He grew up in Finland on a family farm that’s 13 generations old (and the 14th generation is growing up fast). There he learned to respect Mother Nature and started Four Sigmatic with a bunch of other Funguys. Now we’re in over 65 countries, bringing feel-good Nordic traditions to the world.

The World's 100 Top Foods

We grew up in nature, foraging Chaga in our backyards, and eating all kinds of mushrooms for their benefits. Apparently most of the world doesn’t use mushrooms (or their mobile phones) in this way. So we decided to spread the word.

Four Sigmatic foods are the 100 most nutrient dense, most studied foods on the planet. And now they’re easy to add to your daily routines. We’re making these foods as easy as possible to eat and use and talk about. Because the world is asking more of you. Of everyone. We’d all feel a lot better doing that work if we got off the hamster wheel of coffee jitters and hangovers and sugar highs.

HIGHEST QUALITY INGREDIENTS

Rigorously researched and lab tested

We don’t take ourselves too seriously. But our products are no joke. We only use the most studied ingredients from the most trusted sources. We geek out about our formulas and purity levels from our 3rd party testers so you don’t have to think about the science. Unless you want to. In which case, stop by our FAQs.
