Hi-D

Hi-D is an Australian, family-owned wellness brand redefining how people access Vitamin D. Based in the Northern Rivers region of New South Wales, the company specialises in creating plant-based, whole-food Vitamin D using 100% organic shiitake mushrooms.

By combining nature with innovation, Hi-D uses bespoke UV technology to activate Vitamin D directly within the mushroom—preserving its full nutritional profile without the need for chemical extraction, fillers, or additives.
