🌿 Quercetin, Fisetin and Luteolin: The Triad of Natural Senolytic Therapy
Three flavonoids studied against "zombie cells" - let's look at what works
Quercetin, fisetin and luteolin are natural flavonoids studied as senolytics - substances that help remove "senescent" cells. This is one of the promising topics in longevity.
Senescent cells accumulate with age and release substances that accelerate aging. Senolytics aim to remove them. Let's look at what is known about three natural candidates.
What are senolytics
Senolytics are substances aimed at selectively removing senescent cells. This is a new direction in anti-aging medicine.
Senescent cells
Senescent cells stop dividing but do not die. They release substances (SASP) that increase inflammation and affect neighboring cells.
Quercetin
Quercetin is a common flavonoid from apples, onions and berries. It is one of the most studied natural senolytics.
Fisetin
Fisetin is a flavonoid from strawberries, apples and persimmon. It is considered one of the strongest natural senolytics.
Luteolin
Luteolin is a flavonoid from parsley, celery and chamomile. It is also studied as a senolytic and anti-inflammatory.
Research
What research shows about the three flavonoids.
| Substance | Level of data |
|---|---|
| Quercetin | Cells/animals, some human studies |
| Fisetin | Cells/animals, promising |
| Luteolin | Cells/animals, early stage |
What matters
How to sensibly approach senolytic flavonoids.
Understand the status
This is a promising but early field. Not a "proven anti-aging medicine".
Get them from food
Quercetin, fisetin and luteolin are in vegetables and fruits. This is a safe basis.
Supplements - cautiously
High flavonoid doses are being studied. Taking large doses - consciously and as prescribed.
Lifestyle is the foundation
Sleep, nutrition and activity remain the main levers of longevity. More in the material on sirtuins.
What are senolytics?
Substances aimed at selectively removing senescent cells.
What are senescent cells?
Cells that stopped dividing but did not die; they release inflammatory substances.
How does quercetin act?
Studied for its ability to affect senescent cells; often combined with dasatinib.
Does fisetin help with aging?
In mice, fisetin reduced senescent cells and extended healthy life. Human data are limited.
What is luteolin?
A flavonoid from parsley, celery and chamomile. Studied as a senolytic and anti-inflammatory.
Where is quercetin found?
Onions, apples, capers, berries, green tea. This is an accessible source of flavonoids.
Are senolytics proven for humans?
No, effects in humans are still being studied. Most data are from cell and animal models.
Are flavonoid supplements safe?
At food doses yes. High doses in supplements are studied; caution is needed.
What matters more - senolytics or lifestyle?
Lifestyle (sleep, nutrition, activity) remains the main lever. Senolytics are an early field.
