[Functional Food with Proven Results] Enhanced absorption by approximately 20 times through Phytosome technology. Anti-allergy, removal of aging cells, sports, response to COVID-19, etc.
"Kersefit" is a high-absorption type of quercetin derived from the Enju plant, currently under patent application. Thanks to Indena's unique phytosome technology, its bioavailability has been significantly improved by about 20 times, making it a highly regarded quercetin material that supports overall health. It has been adopted in over 50 products worldwide, with more than 10 products already utilizing it in Japan, and its track record is gradually increasing. The mechanisms of action of quercetin can be broadly divided into four categories: 1. Powerful antioxidant properties 2. Strong anti-inflammatory effects 3. Broad immune-modulating effects 4. Extensive antiviral effects Indena's clinical trials on Kersefit in humans: ◆ Accepted as a functional food for "nasal discomfort" due to pollen allergies. ◆ Anti-aging effects through the removal of senescent cells (senolytics). ◆ Histamine inhibition effects on the skin in healthy individuals. ◆ Performance enhancement effects for triathletes. ◆ Relief of symptoms in asthma patients. ◆ Treatment effects and infection prevention effects in mild COVID-19 patients (3 reports). ◆ NEW Treatment for corneal/conjunctival injuries (case report). *For more details, please refer to the PDF materials or feel free to contact us.

Applications/Examples of results
The most notable application is the ability of quercetin to remove senescent cells (senolytics), which are aging (zombie) cells that accumulate in the human body as we age. As a true "anti-aging" material for the era of 120-year lifespans, senolytics is a rapidly advancing field that has garnered the attention of medical researchers worldwide, and quercetin is progressing in human clinical trials as a senescent cell removal drug. Examples of adoption in Japan: ◆ Combined with NMN, resveratrol, and CoQ-10 as an anti-aging supplement ingredient. ◆ Used in functional foods labeled for "nasal discomfort" for products targeting pollen allergies and year-round allergies. ◆ In sports supplements for muscle and endurance, combined with protein, various amino acids, and CBD. ◆ As a supplement for medical institutions (for the prevention and adjunctive treatment of COVID-19). *For more details, please refer to the PDF document or feel free to contact us.
