SHII: Where nature and science find harmony

It’s time to make room for mushrooms in your medicine cabinet. Our founder, Klaudia Wrobel, Ph.D., believes AHCC®, a proprietary extract naturally sourced from shiitake mushrooms, is the answer to countless immune-related issues. Following a close friend’s health struggle, the clinical psychologist and psychotherapist witnessed the ingredient’s life-enhancing impact first-hand. Provided with this knowledge — which is backed by more than 30 human clinical trials — she vowed to make AHCC® mainstream by launching SHII, a wellness brand that never compromises on sourcing quality ingredients, setting quality standards, and improving your quality of life.
