What is Reishi Extract?

Reishi extract is derived from the Reishi mushroom, a mushroom with the scientific name Ganoderma lucidum. It is often referred to as the "Mushroom of Immortality" due to its various longevity-promoting properties; it has been utilized in traditional Asian medicine systems for millennia. Reishi is a decomposer fungus that grows on the stumps and trunks of dead trees. It is often described as having a tough, woody texture and a bitter flavor.

Reishi extract is rich in polysaccharides-believed to support immune function and cellular health, and triterpenes (ganoderic acids), which impart the mushroom's bitter taste and are associated with stress regulation, liver support, and anti-inflammatory effects.

Undersun produces Reishi extract from the mushroom's fruiting bodies using water and ethanol extraction, yielding specifications of ≥20.0% polysaccharides, ≥35.0% beta-glucans, and ≥6.0% triterpene acids. The entire production process involves strict controls regarding microorganisms, heavy metals, and pesticide residues. We maintain a stock of 5,000 kg of Reishi extract powder in our US warehouse, ensuring rapid delivery and the ability to meet your ongoing order requirements.
