E=MC2; Energy = Mushrooms Coffee2

Mushroom Coffee is specifically designed to boost your energy levels gently – the perfect way to keep you going for hours.

Surprisingly, the brain uses 20% of our energy even though it’s only 2% of our body weight. This explains mood changes and why productivity levels decrease when your energy levels are low.

Mushroom Coffee’s intriguing combination of high-quality organic coffee, as an instant stimulant, and superfood mushrooms optimize and nurture your body for high efficiency, help you effectively seize the day, every day.

Delicious organic Arabica coffee, from the high altitudes of South America.


WildMediterranean chanterelles collected from pristine Croatian forests.
This nourishing bomb (A+ score), delivers the highest known natural concentrations of vitamins D and B. These wild wonders are also extremely rich in essential minerals including iron, copper, potassium, and manganese.
Using chanterelles in every cup of Mushroom Coffee, gives you a high dose of nutrients responsible for:

  • converting food into energy
  • serotonin production
  • triggering enzymes involved in neurotransmitter synthesis and nerve growth

Chanterelles are an indispensable ingredient giving you the right amount of energy and helping you stay productive – keeping you in a good mood for hours.

An ancient Tibetan cognitive and physical performance booster. Cordyceps is a go-to mushroom for storming through an exhausting day and it is also widely accepted in professional athletes’ circles as a great natural remedy used to:

  • increase cellular bio-energy (the ATP/IP ratio) by 28% to 55%
  • improve oxygen uptake/aerobic capacity and ventilation function together with resistance to fatigue
  • make their immune systems smarter and highly adaptable to ongoing threats (bidirectional modulator).
  • fight diseases and infections (a powerful antioxidant with ORAC score-12,328)

    Cordyceps works really well before my workouts and this showed to be terrific combination to lift me up. Bit pricey though, and I already have a pile of boxes I feel bad throwing away. Some refill option would be nice.

    Great for energy and focus boost when you loose concetration.
    Go Sharp exceed my expectations. I’m trying to drink coffee only when I really need to. So far I have finished 2 boxes and it feels great to nurture my body instead of overstimulating it when I feel tired.

    It has become part of my mourning routine. Fast to prepare, a lot of fantastic mushrooms and delicious foamy finish with chocolate aftertaste.

  6. Rated 3 out of 5


    Too pricey for my budget

    My secret is to use almond or soy milk with this. Tastes divine

    Love mushrooms and this is the best tasting instant coffee I have tried.

    I have been drinking Go Sharp for 3 months now. Packaging is beautiful but impractical in a long run as I have bunch of boxes now all over my home, which I feel sorry to throw away.
    Beverage by itself makes significant upgrade from regular coffee. My focus periods last for much longer and in overall it is powerful and steady energy experience.

    Inace ne pijem nikakvu kavu, nikad ni nisam, niti bilo kakve varijante i izvedenice (cappucino i sl.) no ovdje me privuklo to sto ima gljiva i odlucio sam probati, ne dodajem secer ni nista drugo, prelijem obicnom kavom i lagano pijuckam tokom cijelog dana i bas sam zadovoljan proizvodom. Lijepi pozdrav

    Beta Glucans are super powerful. Please make cocoa :))), I like much better than coffee.

    I bought the product on webshop but it came from Amazon, for some reason.
    Delivery fast fast. Packaging is nice and the boost the coffee gives is decent.

    I meet mushroom cups team in Berlin and I tried the sample. I liked the test but also the team, their enthusiasm and science oriented approach for creating the product. Now I start my every day with Go Sharp!!

  14. Rated 5 out of 5


    Delicious. The beverage has a healthy vibe and puts you in a great place.
    When I purchased it I somehow skipped the part it is instant coffee.
    I never liked any instant coffee I tried, so I was shocked by how delicious it is.

    I will buy again. I started taking Gosharp with me on weekends for my hiking trips.
    It is convenient and does the job for me. I’m not a morning person so the coffee is a must have. I’m happy i found this one.

    One of the sachets was damaged in transport and the company sent me the whole new box.

    Fine product. I’m a big guy and sometimes I need two packets to get me going which can get pricey.
