Immune health – Quercetin is a flavonoid found in plants like apples. It promotes a healthy immune response in the face of seasonal immune challenges, which makes it the perfect addition to your stay-healthy regimen. Quercetin also helps inhibit oxidative stress.

Cardiovascular health – This ability to inhibit oxidative stress (as well as promote a healthy inflammatory response) makes quercetin good for your cardiovascular system. It encourages endothelial health and with it, helps maintain healthy blood pressure already in normal range.

Superior absorption – So why is it that quercetin isn’t more popular. It’s because this nutrient is difficult for your body to absorb. Our Bio-Quercetin formula integrates quercetin into a phytosome—a tiny sphere made out of plant-based lipids (think sunflower seed oil). This makes our quercetin up to 50 times more bioavailable than standard quercetin.

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.

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.
