As a busy individual I didn’t enjoy the constant boiling work of normal raw chaga powders. I tried the actual Instant Chaga product for few days and instantly felt that it’s THE BOMB! When Tero proposed me to take on the 30-day FSF Challenge with Instant Lion’s Mane I didn’t hesitate for a second.

I love all the Four SigmaFoods products, but reishi is my favourite. I travel a lot for work, which often means that I face several different time zones within a relatively short period of time. I have found reishi very helpful to deal with the resulting jetlag and in reducing my stress levels. I always carry instants with me on a plane and the packaging couldn´t be more pracktical. After a cup of reishi I can sit back and relax and maybe also catch some sleep.

When I came across Four Sigma Foods, I was already very interested in fungus. Already with a love of plants and gardens, I thought what beauty and diversity can a Kingdom have if it has more varieties than plants. As a business professional and athlete, I work to manage stress daily. I would like to assist Four Sigma Foods with my experiences in endurance and athletics to share the beauty and power of healing fungus and herbs. I personally used all the mushroom teas and I'm a believer.

You can't always can a juicer and bunch of fresh ingredients. Having Four Sigma Foods tea first thing in the morning is my physical need for having an energized morning.
