▕ Research and Development of LEM & MAK
Recently, fermented foods have been attracting attention as health foods. Fermented foods [LEM][MAK] developed by Noda Shokubutsu Kogyo are packed with unknown power that has yet to be elucidated, with more than 90 patents, 100 papers published, and presentations at domestic academic conferences. We aim to establish a variety of backup systems, including product development by researchers in our own laboratory, sales and support by our sales staff, and the pursuit of evidence through our network of medical institutions and public organizations.
At Noda Shokukin, we place great importance on scientific evidence for our ingredients. We have obtained a number of various patents based on this data and strive to ensure the reliability and certainty of our products through academic papers.

▒ Collaborative Research
We conduct joint research with universities and medical institutions and publish the results in academic papers. We are working to expand the possibilities of functional foods in collaboration with the Japanese Pharmaceutical Society, Complementary and Alternative Medicine (CAM), and the field of integrative medicine.

▕ Evidence: LEM Academic Reports example
•Treatment of HBeAg-positive chronic hepatitis with LEM (Author: Dr.Harada/Dr.Kanetaka)
•Polysaccharides Improve Immunocompetence in HIV-Infected Patients (Dr.Shirahata etc.)
•Treatment of hepatitis B patients with Lentinus edodes mycelium (Dr.Amagase)
LEM may improve immunocompetence in HIV-infected patients, and further studies are expected.
•The study aims to elucidate the antiviral & immunopotentiating effects of LEM against influenza virus.
•Effects of LEM:
•Direct inhibition of the early stages of viral infection (entry and uncoating).
•Promotion of interferon-β (IFN-β) production, thereby activating immune responses.
•Decreased viral load and dramatic reduction in lung inflammation.
•In Vitro Experiments:
•LEM inhibited plaque formation in a dose-dependent manner, achieving over 85% suppression at maximum concentration.
•Minimal cytotoxicity was observed.
•In Vivo Experiments:
•Intranasal administration of LEM improved survival rates in mice.
•Oral administration reduced the severity of pneumonia and decreased pulmonary lesions.
•Early activation of IFN-β production effectively suppressed viral spread.
•Overall Conclusion:
•LEM has the potential to inhibit influenza infection through direct antiviral action and enhancement of immune responses.
