I can carry a Four Sigma Foods sachet with me in my bag and have one of the best cups of tea in the world, any time, any place. Good for you, delicious, and easy to use – what more could you ask for?

I’m not sure that I could choose my favourite Four Sigma tea because I love them all! Having a cup of the Chaga, Cordyceps or stamina tea each day will make a difference to your health- just try them!

I am not usually a big fan of supplements and also use maca, cacao and coconut rather for culinary pleasure. However, Instant Lion’s Mane REALLY works, at least on me!

My active lifestyle that combines work, training, and socializing is often very demanding. Instant Cordyceps gives me much needed extra energy, and it tastes really good.

I train at least 4 times per week. After introducing Instant Reishi on my daily alimentation I realized that they lifted up my energy level allowing me to achieve more at the end of every day. That´s why I love it!
