Grifola frondosa
Maitake, also known as “hen of the woods,” is a medicinal mushroom traditionally used in Japanese and Chinese medicine. It has gained scientific interest for its potential effects on immune function, metabolic health, and inflammation.
Maitake is particularly rich in beta-glucans, a class of polysaccharides known to interact with the immune system and influence metabolic pathways. While human evidence is more limited than for some ingredients, a growing body of research supports its role in supporting cardiometabolic and immune health.
Maitake contains several key bioactive compounds:
- Beta-glucans — immune-modulating polysaccharides
- Polysaccharides (D-fraction) — linked to immune and metabolic effects
- Antioxidants — helping reduce oxidative stress
- Vitamins and minerals — including B vitamins and potassium
These compounds underpin Maitake’s effects on immune and metabolic systems.
