New Mayo Clinic Human Trial More Than Doubles Fisetin Protocol Dose

One of the hallmarks of aging is the accumulation of senescent or "zombie" cells. Senescent cells are cells which have reached their maximum cellular division (40 to 60 divisions, also known as the "Hayflick limit"), at which time cells normally undergo apoptosis, a type of programmed cellular death.
As we age, though these senescent cells do not always die off and instead continue to hang around, secreting toxins and influencing cells around them to become senescent (hence the nickname "zombie cells"), which cause inflammation in the body. The accumulation of inflammation leads to more rapid aging.
One of the best known senolytics (substances that can kill senescent cells) is Fisetin, a natural flavinoid. In a new study by the Mayo Clinic called "Targeting Cellular Senescence With Senolytics to Improve Skeletal Health in Older Humans", they substantially increased the amount of Fisetin used to eliminate senescent cells from that used in previous studies (called the Mayo Clinic Fisetin protocol).
The new Mayo Clinic protocol for elimination of senescent cells using Fisetin was increased as follows:
20 mg/kg/day (this is equivalent to around 1,800mg per day for an average 180lb person) for 3 consecutive days, resting one month, then repeating this procedure of 3 days on, one month off for 5 months total. This is a substantial increase over their previous protocol of 2 days on, one month off for only 2 months, showing Fisetin is safe and effective at even higher doses than previously known.
