Patented technology licensed from the leading research institute in Taiwan. Reishi or ‘Lingzhi’ is a mushroom that has been used in traditional herbal medicine for more than 4000 years in China, Japan, and Korea. In Chinese, Reishi means “herb of spiritual potency.” Due to its many health benefits without side effects, Reishi has earned a reputation in the East as the ultimate herbal substance, a status unmatched by even the most popular and effective herbs such as Cordyceps and red yeast rice, because it provides numerous health benefits without any side effects. Reishi has been included in the American Herbal Pharmacopoeia and Therapeutic Compendium.

Studies have shown that F3 can stimulate the activity and proliferation of umbilical cord stem cells, natural killer cells and macrophages (defenders of the immune system). F3 uses only the most biologically active polysaccharides from the Reishi herb, as compared to the crude extracts used by other leading supplement brands.
