Quercetin, Fisetin, and Berberine are three vital active ingredients in longevity medicine that primarily target cellular cleansing and cell metabolism. While Quercetin and Fisetin act predominantly as senolytics (meaning they eliminate aged, so-called senescent “zombie cells”), Berberine mimics the effects of fasting in the body. Another essential factor for biological cellular rejuvenation is the molecular strengthening of mitochondria.
Fisetin: The Cellular Cleansing Molecule
Fisetin is a flavonoid found in strawberries, among other sources, and is considered in aging research to be one of the most powerful natural senolytics:
Elimination of “Zombie Cells”: In old age, some cells persist in a state of senescence. They no longer divide but do not die off either. Instead, they secrete inflammatory substances that damage healthy tissue. Fisetin stimulates the immune system to neutralize these harmful cells.
Anti-inflammation: By eliminating senescent cells, the chronic inflammation level throughout the entire body (often called inflammaging) decreases.
Cognitive Protection: Studies also indicate that Fisetin can cross the blood-brain barrier and protect nerve cells in the brain from age-related decline.
Quercetin: The Cell Protector and Enhancer
Quercetin, found in onions and apples, is structurally closely related to Fisetin, but acts more broadly on the immune system and blood vessels:
Combined Senolytic: Quercetin enhances the flushing out of senescent cells. In science, it is often combined with other substances for maximum effects.
Vascular and Heart Protection: Quercetin promotes the elasticity of blood vessels, supports blood circulation, and can help regulate blood pressure.
Antioxidant Power: Quercetin efficiently neutralizes free radicals and protects cells from oxidative stress.
Berberine: Activator of Cellular Fasting Processes
Berberine is an alkaloid derived from plants like barberry. In contrast to the other two substances, its focus is not on cell elimination, but on controlling cellular energy. It is often referred to as the natural equivalent to the medication Metformin, which acts very similarly but is less well tolerated by quite a few people:
AMPK Activation: Berberine activates the enzyme AMPK (adenosine monophosphate-activated protein kinase). This is the body’s central “fuel sensor,” which normally kicks in through calorie restriction (fasting) or intense exercise.
Autophagy Starter: AMPK activation initiates autophagy—the internal cellular recycling program where defective proteins and cell components are broken down and reused.
Blood Sugar and Lipid Metabolism: Berberine improves the insulin sensitivity of cells. It helps transport glucose more effectively from the blood into the cells, which is why it is often compared to the diabetes medication Metformin in studies. It also aids in weight loss.
The Interplay at a Glance
| Substance | Main Mode of Action | Primary Goal in Longevity |
|---|---|---|
| Berberine | AMPK Activation (fasting mimicry) | Blood sugar regulation and cell recycling (autophagy) |
| Fisetin | Senolytic (elimination of zombie cells) | Tissue rejuvenation and reduction of inflammation |
| Quercetin | Antioxidant and senolytic | Vascular protection, immune system, and cell protection |
Note on Therapeutic Application
These substances are not common dietary supplements like collagen or vitamin C. They remain the subject of scientific and clinical investigation and are available neither as standard dietary supplements nor as approved medications. Furthermore, there are no official dosage guidelines yet.
To utilize these substances in the required purity and quality for therapeutic purposes, one should not purchase them from questionable sources on the internet and dose them in self-experiments. Instead, treatment should only be undergone under the supervision of an experienced physician. The doctor understands the effects of these substances, knows the individuality of the patient, and can assess potential side effects or interactions with other medications being taken.
Strengthening the Mitochondria
With increasing age, the efficiency of the cell powerhouses, the so-called mitochondria, declines. Those affected report fatigue and a loss of vitality. Strengthening the mitochondria can help counteract this decline in physical performance. Modern longevity medicine relies on a combination of administering specific active ingredients and other innovative therapies.
Infusions with NAD+ and the intake of NMN can stimulate the formation of new mitochondria (biogenesis) and help protect mitochondrial DNA (mtDNA). By taking the postbiotic Spermidine, the cleansing of cells from cellular waste and damaged proteins can be promoted, supporting the body’s own autophagy. Cellular rejuvenation is supplemented by Hyperbaric Oxygen Therapy (HBOT). Inhaling oxygen under increased pressure followed by a drop in pressure improves cell respiration and strengthens the mitochondria.
Frequently Asked Questions About Biological Cell Rejuvenation
What do biological cellular rejuvenation and autophagy mean?
Biological cellular rejuvenation aims to slow down or reverse the aging process at a molecular level. Through the targeted use of senolytics like Fisetin and Quercetin, aged “zombie cells” are broken down. Additionally, longevity therapy uses active ingredients like Berberine to boost autophagy—the cellular self-cleansing program that breaks down damaged cell components and replaces them with new ones.
What exactly do Fisetin and Quercetin do in the body?
Quercetin and Fisetin belong to the group of polyphenols (secondary plant substances) and act as senolytics. They help the body detect and break down cells that are no longer capable of dividing, which would otherwise promote inflammation (so-called inflammaging) in the tissue. Quercetin protects cells from oxidative stress and assists the body in removing old cell structures. Fisetin penetrates deep into tissues, such as the brain, and promotes the breakdown of cellular waste products, which in turn supports regeneration.
What role does Berberine play in longevity therapy?
Berberine is a natural plant alkaloid that regulates cellular energy metabolism and directly intervenes in the metabolic pathways responsible for longevity. It activates the so-called AMPK kinase, an important enzyme that signals the body to conserve energy and ramp up cellular renewal processes (autophagy). Furthermore, Berberine can improve the insulin sensitivity of cells, allowing glucose to be channeled out of the blood more effectively. Due to this metabolic effect, it is frequently compared to the well-known diabetes drug Metformin in scientific studies and can also assist in weight loss.
What is meant by molecular strengthening of the mitochondria?
Mitochondria are the powerhouses of our cells. With increasing age or due to chronic stress, their function declines, leading to fatigue and poor performance. Specific longevity treatments aim to repair damaged mitochondria and stimulate the formation of new ones.
Why is induced autophagy so important?
Autophagy is the body’s own “recycling process”. It ensures that damaged proteins, defective cell components, and even harmful pathogens are broken down and converted into new, healthy building blocks. Since this vital process declines with increasing age, it is induced in our clinic through targeted micronutrient combinations to cleanse and renew the cells from the inside out.
Are these therapies suitable for everyone?
Fundamentally, these treatments are aimed at individuals who want to act preventatively, increase their performance, or slow down age-related degradation processes. However, since high-dose active ingredients like Quercetin and Fisetin can interfere with the body’s own metabolism of medications, they are only recommended for pregnant women, breastfeeding mothers, or individuals taking certain medications regularly after strict medical consultation.
How does a treatment session work in the clinic?
Therapy always begins with a comprehensive analysis in our clinic. Based on your individual health status and your therapy goals, we create a customized treatment plan tailored to your needs. The active ingredients are mostly administered in the form of oral preparations.
