Autophagy is your cells' natural cleanup system, recycling damaged parts to keep them healthy and functional. Activating autophagy is linked to slowing aging, improving brain and heart health, and reducing risks of diseases like cancer and diabetes. While fasting can trigger autophagy, certain natural compounds make it easier to support this process without drastic lifestyle changes.
Here are the top compounds that activate autophagy and how they work:
- Spermidine: Found in foods like mushrooms and green peas, it promotes autophagy by targeting acetylation processes.
- Resveratrol: Found in grapes and red wine, it activates SIRT1 and AMPK, enhancing energy metabolism and cellular health.
- Curcumin: Found in turmeric, it supports autophagy and provides anti-inflammatory and brain health benefits.
- Fisetin: Found in strawberries and apples, it clears damaged cells and supports cognitive function.
These compounds work through pathways like mTOR, AMPK, and PI3K/AKT to mimic the effects of fasting, helping your cells stay clean and efficient as you age. Supplements can help achieve therapeutic levels when dietary intake isn’t enough.
| Compound | Key Benefits | Sources |
|---|---|---|
| Spermidine | Longevity, brain health | Mushrooms, green peas |
| Resveratrol | Mitochondrial health, neuroprotection | Grapes, red wine |
| Curcumin | Anti-inflammatory, brain health | Turmeric |
| Fisetin | Clears damaged cells, cognitive support | Strawberries, apples |
AUTOPHAGY & MITOPHAGY - 6 NATURAL Compounds & Lifestyles To Activate
How Natural Compounds Activate Autophagy
To understand how natural compounds activate autophagy, it’s essential to look at the cellular systems that regulate this process. These compounds interact with specific molecular pathways, acting as switches that either turn autophagy on or off, depending on the cell's needs.
Key Cellular Pathways
Autophagy is primarily regulated by three major signaling pathways: mTOR, AMPK, and PI3K/AKT. Each pathway responds differently to natural compounds, providing multiple ways to initiate the cell's cleanup process.
- mTOR Pathway: Think of mTOR (mechanistic Target of Rapamycin) as a brake on autophagy. When nutrients are abundant, mTOR is active and suppresses autophagy by phosphorylating proteins like ULK1 and ATG13. However, when mTORC1 is inhibited - such as during nutrient scarcity - these proteins are freed to kickstart autophagy. Studies link nutrient-induced mTOR activation to reduced autophagy [2].
- AMPK Pathway: AMPK (AMP-activated protein kinase) acts as an accelerator. This energy sensor gets activated when cellular energy levels are low, such as during fasting. It works to restore ATP levels by halting energy-consuming processes and promoting catabolism. AMPK also boosts autophagy by phosphorylating ULK1, counteracting the inhibitory effects of mTOR [3].
- PI3K/AKT Pathway: This pathway's role in autophagy is more flexible - it can either enhance or suppress autophagy depending on the specific natural compounds and cellular context.
These pathways allow natural compounds to mimic stress signals, effectively flipping the switch to activate autophagy.
Autophagy Activation Triggers
Natural compounds activate autophagy by simulating conditions like nutrient scarcity or mild oxidative stress. For example, fasting or calorie restriction naturally triggers autophagy, and certain compounds replicate these effects. Additionally, some compounds induce mild oxidative stress, which activates the cell's defense systems, making it more resilient to future challenges.
Another key mechanism involves changes in protein acetylation. Resveratrol, for instance, activates SIRT1, a NAD⁺-dependent deacetylase that removes acetyl groups from proteins, thereby promoting autophagy. On the other hand, spermidine inhibits acetyltransferases, shifting the balance toward deacetylation [4].
Research shows that combining resveratrol and spermidine alters the acetylation status of 560 lysine-containing motifs across 375 proteins, with 170 of these proteins being central to the autophagy process [4]. Interestingly, higher doses of these compounds together don’t amplify autophagy further, suggesting they work through overlapping mechanisms.
These compounds also influence acetylation and deacetylation in different parts of the cell. They promote deacetylation in the cytosol while encouraging acetylation in the nucleus, aligning autophagy activation with changes in gene expression [4].
Top Natural Compounds That Activate Autophagy
Let’s dive into some of the most effective natural compounds known to kickstart autophagy - a process vital for cellular renewal and overall health.
Spermidine
Spermidine stands out as one of the most studied polyamines for its role in activating autophagy. It works by inhibiting EP300, which prevents the acetylation of autophagy-related proteins, and blocking α-tubulin acetyltransferase 1 (aTAT1), promoting tubulin deacetylation - both critical for autophagy to function effectively [6]. On top of that, spermidine influences epigenetic regulation by targeting enzymes like E1A-binding protein p300 and other histone acetyltransferases (HATs) [6]. Unfortunately, levels of spermidine naturally decline as we age, making supplementation a practical option [6].
Studies show that oral spermidine supplements, often paired with spermine, can promote autophagy in the hippocampus, delay brain aging, and support cognitive health in mice. In older rats, it’s been linked to heart health benefits, such as reducing myocardial fibrosis and other age-related cardiac issues [8][5]. While spermidine is found in foods like mushrooms, green peppers, green peas, and citrus fruits [5], getting therapeutic amounts solely through diet can be difficult.
Now, let’s explore another compound that not only activates autophagy but also boosts energy metabolism.
Resveratrol
Resveratrol takes a different route to enhance autophagy. It activates SIRT1 and AMPK, two key players in improving mitochondrial efficiency and promoting cellular cleanup [4]. Research highlights how resveratrol increases citrate synthase activity, boosts oxygen consumption, and enhances mitochondrial ATP production [5]. In one study with Wistar rats, combining resveratrol with donepezil increased astrocyte numbers while reducing microglia, suggesting potential protection against neurodegenerative conditions [8].
Curcumin
Adding to the list, curcumin supports autophagy by targeting specific cellular pathways. In diabetic rats with heart damage, combining curcumin with high-intensity interval training enhanced the expression of autophagy-related proteins like ATG-5 and Beclin-1 [5]. Another study involving mice with doxorubicin-induced cardiomyopathy found that curcumin restored autophagy by boosting Beclin-1 levels and the LC3II/LC3I ratio while regulating the AKT/mTOR pathway [5].
Fisetin and Other Flavonoids
Fisetin, a flavonoid found in cucumbers, onions, apples, and strawberries, activates autophagy by engaging p8-dependent pathways and regulating ER stress through PERK, ATF4, and ATF6. It also stimulates the AMPK pathway, further supporting cellular renewal [7]. Other flavonoids, like quercetin and apigenin, work in similar ways by influencing pathways such as mTOR, FoxO1/3, AMPK, and SIRT1. These actions increase autophagy-related proteins like Beclin-1 and LC3 while reducing p62 levels [5]. These compounds have shown neuroprotective effects, including improved memory and cognitive function, and may help clear proteins linked to neurodegenerative diseases [8].

FAQs
How do natural compounds like spermidine and resveratrol compare to fasting for activating autophagy?
Natural compounds such as spermidine and resveratrol play a role in activating autophagy - our body’s natural cellular cleanup system - through specific pathways. Spermidine achieves this by inhibiting histone acetylases, while resveratrol works by activating Sirtuin 1. Both mechanisms contribute to better cellular health and may even support longevity. Unlike fasting, these compounds offer a more focused way to promote autophagy.
Fasting, however, is widely recognized as one of the most effective natural methods for triggering autophagy. It initiates a systemic response throughout the body, promoting cellular repair and renewal. Interestingly, studies suggest that spermidine can replicate some of fasting’s benefits by encouraging autophagy and aiding healthy aging. This makes it an appealing alternative for individuals looking for similar effects without the difficulty of extended fasting.
While fasting delivers a comprehensive, whole-body effect, supplements like spermidine and resveratrol provide a more precise and convenient option for supporting cellular health and longevity.
Can I get enough autophagy-boosting compounds from food, or do I need supplements?
While foods like mushrooms, turmeric, and green tea naturally contain compounds that can support autophagy, relying solely on diet to reach effective levels can be challenging.
