Where it started
It began with my grandmother
When my grandmother was diagnosed with dementia, our family started looking everywhere for hope. That's how I first heard about fisetin — a natural flavonoid found in strawberries, apples, and cucumbers that researchers are studying in preclinical models for cognitive health, neuroinflammation, and pathways linked to neurodegeneration.
She started taking it. And out of caution — and love — I started taking it too, as a preventative measure. I figured the science was interesting enough to be worth a closer look. I had no idea what was coming next.
"I learned the skin and health benefits later. What happened in between surprised everyone — including my doctors."
The science
What the research actually says
Fisetin is what's called a senolytic — a compound that induces apoptosis (programmed cell death) in senescent cells: damaged cells that have stopped dividing but refuse to die. These "zombie cells" accumulate with age and pump out inflammatory signals (the SASP — senescence-associated secretory phenotype) that damage the healthy tissue around them.
Landmark study · 2018
Fisetin: the most potent of 10 flavonoids
Mayo Clinic & Scripps researchers screened 10 flavonoid polyphenols for senolytic activity. Fisetin was the most potent. In aged mice, it reduced senescence markers across multiple tissues, restored tissue homeostasis, and extended both median and maximum lifespan — even when treatment started late in life. It also reduced senescence in human adipose tissue explants.
Brain study · 2024
Resveratrol + fisetin + exercise in Alzheimer's mice
Mice with Alzheimer's-like brain changes received resveratrol + fisetin, aerobic exercise, or both. The combination boosted BDNF ~4.9×, VEGF ~3.5×, and FGF7 ~2.5× — key genes for neuron growth, blood-vessel support, and communication between brain cells. The researchers called the combined effect synergistic.
Human trials
Now being tested in people
Most fisetin evidence so far comes from animal and cell studies. Human clinical trials are now underway to test whether fisetin can safely reduce senescent cell burden in older adults. The science is early — but it's moving fast.
What's inside the bottle
Every ingredient, explained
This is the exact formula I take — Nextdia's liposomal fisetin + resveratrol complex in a liquid-filled gummy. Here's what each ingredient does, with the skin and collagen angle front and center:
200 mg · 98% pure · liposomal
Fisetin
The star of the show. The senolytic flavonoid from the Mayo/Scripps research — the most potent of 10 flavonoids tested at clearing senescent cells.
- Skin: studied for reducing senescent fibroblasts and supporting collagen density
- Brain: studied alongside resveratrol for neuroprotective signaling (BDNF)
- Longevity: extended healthspan and lifespan in aged mice
- Cellular: included in the formula to help maintain glutathione levels and healthy mitochondrial function
500 mg vitality blend · trans-resveratrol
Resveratrol Complex
The famous red-wine polyphenol — here it leads a 500 mg proprietary vitality blend alongside quercetin and luteolin. In the Alzheimer's mouse study, resveratrol + fisetin together outperformed either alone — a true synergy.
- Skin: potent antioxidant; studied for protecting collagen from oxidative breakdown
- Brain: combined with fisetin, boosted BDNF ~4.9× in the 2024 study
- Cellular: researched for supporting sirtuin pathways tied to healthy aging
In the 500 mg blend · 98% pure
Quercetin
Another senolytic flavonoid — in fact, the original one studied alongside dasatinib at Mayo Clinic before fisetin proved even more potent. The two are a classic pairing.
- Skin: antioxidant support against environmental stressors that degrade collagen
- Senolytic stack: complements fisetin's senescent-cell-clearing activity
In the 500 mg blend · 98% pure
Luteolin
A calming flavonoid found in celery, parsley, and chamomile — researched for its neuroprotective and anti-inflammatory properties.
- Skin: studied for soothing inflammatory pathways in skin tissue
- Brain: researched for supporting healthy microglia (the brain's immune cells)
90 mg · 100% daily value
Vitamin C
Not just immune support — vitamin C is a required cofactor for collagen synthesis. Your body literally cannot build stable collagen without it.
- Skin: essential for collagen production; brightens and defends against oxidative stress
- Synergy: recycles vitamin E, keeping the antioxidant network running
15 mg · 100% daily value
Vitamin E
The skin's frontline fat-soluble antioxidant — it lives in your cell membranes and takes the hit from free radicals so your cells don't have to.
- Skin: protects cell membranes and supports the skin barrier
- Synergy: works as a team with vitamin C for full-spectrum antioxidant coverage
5 mg · 95% piperine
Black Pepper Extract
The bioavailability booster. Piperine helps your body actually absorb the flavonoids instead of passing them through — so the 200 mg of fisetin does more work.
- Absorption: added specifically for maximum bioavailability
- Delivery: pairs with the liquid-filled liposomal design
Plus: liquid-filled gummy technology — a liquid center that locks in the nutrients, designed for better absorption — natural peach flavor, 0g cane sugar, vegan, gelatin-free, gluten-free, non-GMO, lab tested, made in GMP-certified facilities. Serving size is 1 gummy; 60 servings per bottle.
Why this combo works
Supporting longevity at the cellular level
This is how I think about what the formula is designed to do — four jobs, one gummy:
01Clear senescent cells
Fisetin is the formula's senolytic — it targets the "zombie" cells that stop dividing but refuse to die, the ones linked to aging and chronic inflammation.
02Promote youthful cell activity
Quercetin supports the body's natural cell renewal and recycling processes — helping clear out the old so the new can thrive.
03Defend against oxidative damage
Vitamins C and E plus luteolin form an antioxidant network that helps shield cells — and the collagen they build — from oxidative stress.
04Support a sharp mind
Resveratrol and fisetin are being researched for neuroprotective signaling — in one mouse study, the combination boosted BDNF, a key brain-health protein.
The gummies use a liquid-filled liposomal design — nutrients suspended in the center rather than baked into the chew — which the brand says improves absorption. Just one a day, per the label.
