Functional mushrooms are a category of fungi with documented bioactive properties beyond their nutritional value. Unlike common culinary mushrooms, functional varieties contain high concentrations of polysaccharides (beta-glucans), triterpenes and other compounds that actively interact with the body's systems: immune, nervous, cardiovascular and endocrine.
Demand for functional mushrooms in the US has grown rapidly — driven by consumers looking for natural alternatives for cognitive performance, stress management and preventive health. Zengii formulates a premium Lion's Mane supplement standardized to 30% beta-glucans, shipping to the US and Panama.
