PROMOTE YOUTHFUL CELLULAR FUNCTION – Cellular senescence is a natural part of aging when cells no longer function optimally. They can accumulate over time, affecting the daily function of your healthy cells. But new research indicates that black tea theaflavins and quercetin can make it easier for your body to manage senescent cells.

Product Note: Exposure to heat or sunlight may lead to melting/damage of product. Hence customers are expected to be available during the product delivery

EXPERIENCE A REJUVENATION - Senolytic Activator combines black tea theaflavins, the plant-derived flavonoid apigenin and ultra-absorbable forms of quercetin and fisetin to help manage senescent cells and promote systemic rejuvenation in your body.

Helps clear senescent cells—Cellular senescence is a natural part of the aging process in which cells no longer function optimally. Research shows fisetin is a senolytic compound: a nutrient that actively targets senescent cells by encouraging the body’s natural pathways for clearing senescent cells so that newer, healthy cells can flourish.

Healthy cognition and glucose metabolism—Fisetin helps protect the delicate nerve cells in your brain. Fisetin can also help maintain glucose levels within normal range, which is good for everything from your kidneys to your eyes to how you gain or lose weight.

25x more bioavailable than standard formulas—Fisetin is terrific for whole-body health, but it breaks down during digestion. So we combined fisetin with galactomannan fibers from fenugreek seeds to help preserve fisetin through your digestive system, making it up to 25 times more bioavailable than standard fisetin.

SUPPORTS TELOMERE LENGTH FOR HEALTHY AGING: Provides telomere length and anti-aging benefits safely by optimizing the 5 key processes that impact telomere length: (1) Telomerase Activation, (2) DNA Repair, (3) Nitric Oxide Production, (4) Homocysteine Reduction.

POWERED BY HERBAL EXTRACTS, COENZYMATED VITAMINS & ANTI-OXIDANTS: Clinically proven rainforest extract, AC-11, works with Zinc to repair cellular DNA. Essential coenzyme vitamins 5-MTHF (the active form of folate) and Methylcobalamin (the active form of B12) reduce homocysteine. High potency herbal extracts boost telomerase enzyme production, and a resveratrol / L-citrulline combo enhances nitric oxide.

CLINICALLY STUDIED ACTIVE INGREDIENTS: A clinical study on AC-11 shows telomeres lengthened in 9 of 11 participants taking this extract for 1 year. The telomeres of two participants increased dramatically, moving from telomere lengths typical of age 60+ to those typical of age 40s. AC-11 is a proprietary bioactive rainforest extract proven to enhance cell health. This extract is supported by 17+ years of research, 40+ scientific peer-reviewed studies.
