Our Science

The Difference

We specialize in immune support that thoughtfully considers your unique health journey. We say no to superfluous ingredients and fillers, and instead turn to nature-derived, science-backed ingredients that put your daily immunity first. Each product undergoes rigorous testing to ensure you’re receiving the cleanest, most effective form of immune support, so you can start living life as your most resilient self.

The Perfect Ingredient

When it comes to prioritizing and supporting your immune health, AHCC® — a cultured extract that’s rich in alpha glucans and sourced from the mycelia of shiitake mushrooms — reigns supreme. It’s the mainstay ingredient in our immune-supporting supplements due to its unique, superior absorption in the body, which helps to modulate both the innate and adaptive immune responses.* AHCC® is backed by more than 30 human clinical trials and used by over 1,000 clinics worldwide.

Before After

Ingredients that make a difference

Life is about stepping back and assessing the whole picture. We share the same sentiment regarding the sourcing of our product. While AHCC® is at the center of why we do what we do, SHII also boasts other active, highly targeted ingredients — such as vitamin C, vitamin D3, zinc, magnesium, and a uniquely tailored blend of mushrooms — to bring forth a natural solution to a compromised immune system.
