What is Spermidine?
Spermidine is a naturally-occurring polyamine that induces autophagy, your body's cellular "clean up" and recycling process. It also targets 9 of the 12 root causes of aging, known as the "Hallmarks of Aging".
When you are young, you produce 2/3 of your spermidine content needs in your gut biome and body tissues. The final 1/3 comes from your diet.
As you age, your body's ability to produce it declines and you become much more reliant on food-derived, supplemental sources.

Spermidine supplementation in humans has been shown to have several positive effects including protecting brain and heart health, improving hair growth and fullness, and strengthening nails.
Epidemiological studies associate spermidine intake with a longer life.

According to a landmark paper by Lopez-Otin et al, aging is driven by 12 “hallmarks”. Among them are impaired autophagy, stem cell and mitochondrial dysfunction, inflammation, and gut dysbiosis, which all are known to be reduced by spermidine supplementation.
Spermidine is one of few known compounds thought to reduce or reverse the effects of multiple hallmarks; through its induction of autophagy, in particular, it is thought to impact 9 of the 12 hallmarks.

Autophagy is a Greek word that translates to mean "self eating". It refers to a vital cellular "clean up" and recycling process that clears out old cellular debris to make way for new, healthy ones.
It is so ground-breaking that the Japanese scientist, Yoshinori Ohsumi, who discovered its mechanism of action won the Nobel Prize (and we are the only non-Japanese company to work with him and his team!)

Professor Denis Noble
World-Renowned Physiologist & Emeritus Professor of Physiology, University of Oxford (Oxford)
Professor Denis Noble is a globally-recognized British biologist who developed the first mathematical model of cardiac cells in 1960. He held the Burdon Sanderson Chair of Cardiovascular Physiology at the University of Oxford from 1984 to 2004 and was then appointed Professor Emeritus and Co-Director of Computational Physiology.
On an international scale, he was elected President of the International Union of Physiological Sciences (IUPS) at its Congress in Kyoto in 2009, and then elected for a second term at the 2013 Congress in Birmingham, UK. As a pioneer in the field of systems biology, he is the author of the first popular book on Systems Biology, The Music of Life. His book, Dance to the Tune of Life, Biological Relativity, extends the systems approach to biology, including evolutionary biology. Denis Noble has published more than 600 papers and 11 books. Together with Leslie Kenny, Dr. Paul Ch'en and Sir Christopher Ball, he is a co-founder of the non-profit organization, Oxford Longevity Project.
Dr. Ghada Alsaleh
Principal Investigator in Immunology and Autophagy & Leader of the UK's First Space Innovation Lab, University of Oxford (Oxford)
Dr. Ghada Alsaleh moved to Oxford in 2017 to pursue her career as a scientist and to join Professor Katja Simon’s group at the University of Oxford's Kennedy Institute for Rheumatology, where she developed a growing curiosity about aging and the regulation of biological processes that are disturbed during the aging process. In her research, she showed that autophagy is specifically reduced in older human lymphoid cells, which contributes to compromised memory T and B cell responses in the elderly. This work has uncovered novel targets and biomarkers for the development of anti-aging drugs for human T cells.
Dr. Ghada was awarded funding for her proposal “Targeting autophagy for the treatment of osteoarthritis”. Osteoarthritis (OA) is the most common form of arthritis worldwide but lacks effective therapy. In this proposal, she aims to design a genetic screen using TFEB protein expression as a read-out to identify new potential targets for the treatment of Osteoarthritis and various age-related diseases. She has recently become leader of the UK's first Space Innovation Lab, which aims to understand the effect of space microgravity on the aging process.
Dr. Katja Simon
Oxford University Professor of Immunology & Head of the "Autophagy in the Immune System" laboratory, Max Delbruck Center (Berlin)
Dr. Katja Simon began her autophagy research as Professor of the Immunology at the Kennedy Institute for Rheumatology, University of Oxford. As a principal investigator, she set up an independent line of enquiry investigating autophagy, another cellular process determining cell fate, in the hemato-immune system. Her group discovered that autophagy, the main conserved cellular bulk degradation pathway, maintains healthy red blood cells, stem cells and memory T cells and promotes differentiation while preventing aging of the hematopoietic system. She has since been appointed to Head of the "Autophagy in the Immune System" laboratory at the Max Delbruch Center in Berlin as part of an initiative to attract outstanding female scientists from abroad. She and her team are continuing her research on autophagy in the immune system there.

Dr. Olivia Lesslar
Celebrity Longevity Doctor, TEDx Speaker & NYC Journal 50 Under 50 (Global)
Dr. Olivia Ly Lesslar is an Australian medical doctor who specializes in complex chronic conditions including neurodegeneration, "mystery illnesses", atopy, cancer, and psychoneuroendoimmunology - the intersection of psychology, hormones, the nervous system, and the immune system. After her medical residency in Australia, she worked across the USA: First with double-board certified neurologist and psychiatrist Dr. Jay Lombard at the Neuroimmunology Associates of New York and currently, with Dr. Chris Renna at LifeSpan Medicine, Los Angeles. Since 2020 she has spent more time in her home country of Australia, and now works with internationally renowned Professors - neurosurgeon Charlie Teo and immunologist allergist Pete Smith at their respective clinics. In 2022, she was featured in the NYC Journal 50 under 50 as a distruptor in her industry.
