Harnessing Natural Solutions to Improve Metabolic Health

Harnessing Natural Solutions to Improve Metabolic Health

The term “metabolism” is typically used to describe your weight, how much you can eat without gaining weight, or how looking at ice cream makes you pack on the pounds. In truth, metabolism is the summation of all of the chemical processes that happen in all of your cells that maintain the living state. So, when you say that you want to improve your metabolism, you’re not just saying you want to be able to eat the ice cream and not gain weight. You’re also saying that you want your cells to keep doing all the things that keep you alive. 

In the pursuit of better metabolic health, researchers have long explored the potential benefits of various drugs and interventions. One such intervention, metformin, has shown promise in its ability to improve cellular metabolism. Many people are currently prescribed metformin as a way to manage their blood sugar. In the United States, metformin is prescription only, but in some other countries, it’s sold over the counter. It’s listed as one of the WHO’s most valuable drugs for human health. But is blood sugar balance the only thing it's good for? 

Recent studies have identified natural compounds that mimic the effects of metformin. By harnessing the power of these natural mimetics, you can potentially improve your metabolic health and reduce the risk of chronic diseases. Keep reading to learn about the research surrounding these natural compounds and explore how they can be incorporated into a holistic approach to improved metabolism for better health and a longer life. 

The Power of Natural Mimetics 

Metformin, a common drug used to manage blood sugar has been found to have significant longevity promoting effects. However, its use is limited by strict regulations. To overcome these limitations, researchers and individuals are turning to natural compounds that can mimic the effects of this drug without the risk of side effects that some people may experience with metformin use. By incorporating these natural mimetics into your longevity plan, you can potentially harness the power of these compounds to improve your metabolic health. 

Metformin Mimetics: A Promising Approach 

Metformin has been shown to have various metabolic benefits. It can help lower fasting plasma glucose (FPG), reduce glycosylated hemoglobin (HbA1c) levels, and improve insulin sensitivity. However, the side effects and regulatory limitations associated with metformin have led researchers to search for natural alternatives. 


Native to several plants, berberine is often highlighted for its potential in managing blood sugar and lipid metabolism disorders. Mechanistically, it functions similarly to metformin by activating AMP-activated protein kinase (AMPK), an enzyme crucial for maintaining energy homeostasis. Activation of AMPK improves insulin sensitivity, inhibits lipid synthesis, and enhances glucose uptake in cells. Beyond its metformin-like actions, berberine also demonstrates anti-inflammatory, anti-proliferative, and antioxidant properties, potentially offering broad-spectrum health benefits. 


Found in several botanical extracts, allantoin is known for its skin-soothing properties. Like metformin, it can activate AMPK. Its potential in metabolic regulation, however, is less studied compared to berberine. Allantoin stands out for its potent cell proliferative and wound-healing properties, suggesting it may be especially beneficial for skin health and repair when used topically. 


Extracted from the ginseng plant, ginsenosides are a diverse group of steroidal saponins. They not only stimulate AMPK activity but also influence glucose transporters (GLUTs), enhancing glucose uptake in cells. This dual action mirrors metformin's method of improving cellular glucose utilization. Beyond this, ginsenosides exhibit neuroprotective, anti-inflammatory, and anti-proliferative properties, positioning ginseng as a multifunctional herb in traditional medicine. 

Epigallocatechin Gallate (EGCG) 

As the main polyphenol in green tea, EGCG is renowned for its antioxidant capability. Like metformin, EGCG can activate AMPK, fostering improved metabolic function. Additionally, EGCG aids in reducing lipid absorption in the intestines and has thermogenic properties, suggesting potential utility in weight management. Its renowned antioxidant properties combat oxidative stress, and it's also associated with potential anti-proliferative, anti-inflammatory, and neuroprotective benefits, making green tea one of the most widely consumed health beverages.

This flavonoid, primarily found in licorice root, showcases promise as a metformin mimetic. By activating AMPK, isoliquiritigenin mirrors metformin's glucose-lowering effects. Beyond this mechanism, it's also known for its anti-inflammatory and antioxidative activities. Interestingly, studies have also highlighted its potential as a way to maintain DNA integrity, particularly in animal models prone to uncontrolled cell growth in estrogen-dependent tissues. 

Withaferin A 

Derived from the ashwagandha plant (Withania somnifera), withaferin A is a steroidal lactone with multi-faceted health implications. While its AMPK activation draws parallels with metformin, withaferin A also possesses unique properties. Notably, it exerts anti-proliferative effects by inducing apoptosis in abnormal cells. Furthermore, it boasts anti-inflammatory actions, potentially offering relief in conditions like achy or sore joints. As an adaptogen, withaferin A may also aid in stress reduction and supporting mental well-being. 

Comparative Analysis 

While each of the discussed compounds bears a resemblance to metformin in terms of AMPK activation and, consequently, potential metabolic benefits, their individual additional properties diversify their utility in health and wellness. For instance, while berberine and ginsenoside offer a robust resemblance to metformin’s glucose and lipid regulatory effects, EGCG’s unique contribution to weight management through thermogenesis and lipid absorption reduction is noteworthy. On the other hand, isoliquiritigenin and withaferin A bring anti-proliferative properties to the table, potentially offering therapeutic benefits beyond metabolic regulation.  

Exploring Other Natural Solutions 

Beyond these metformin mimetics, there are additional natural compounds that offer potential benefits for metabolic health. Researchers are increasingly spotlighting these substances for their multifaceted health implications. 


Predominantly found in grapes, red wine, and certain berries, as well as the invasive Japanese knotweed, resveratrol has gained substantial attention for its potential anti-aging properties. Its mechanism of action involves the activation of the SIRT1 gene, which plays a role in metabolic regulation. By doing so, resveratrol can enhance insulin sensitivity and mitochondrial function, making it a valuable agent for metabolic health. Additionally, its anti-inflammatory and antioxidant capabilities can mitigate oxidative stress, reducing the risk of complications that arise from metabolic dysfunction. 


The primary active component of turmeric, curcumin stands out for its potent anti-inflammatory and antioxidant properties. It can modulate several molecular targets, including inflammatory pathways, and has been shown to improve insulin sensitivity and combat lipid accumulation in tissues. This, in turn, can have profound effects on mitigating the onset of metabolic slowdown and its associated difficulties. Furthermore, curcumin's neuroprotective properties offer potential benefits for brain health, making it a comprehensive health-promoting agent. 


Abundant in onions, apples, and green tea, quercetin is a flavonoid that boasts a wide array of health benefits. Notably, its anti-inflammatory effects can attenuate insulin resistance, a hallmark of metabolic dysfunction. Moreover, quercetin has demonstrated the capability to improve endothelial function, which is critical for cardiovascular health, especially in the context of metabolic ailments. Its additional antioxidant capabilities offer protection against free radical damage, furthering its value for overall wellness. 

Taking a Holistic Approach to Metabolic Health 

While metformin might offer an interesting pharmaceutical route to longevity, these diet and lifestyle factors remain the foundation in promoting extended healthspan and potentially mirror some of the benefits of the drug. 

Caloric Restriction and Intermittent Fasting  

One of the most well-researched interventions for longevity is caloric restriction (CR) without malnutrition. CR has been shown to extend lifespan across various species, from yeast to primates. The longevity benefits of CR arise from its ability to reduce oxidative stress, improve insulin sensitivity, and stimulate autophagy, a cellular "cleanup" process. Intermittent fasting, a pattern of eating where one oscillates between periods of eating and fasting, has been proposed as a more feasible alternative to constant CR, and has shown promise in improving metabolic health and longevity. However, there is a selection of people who don’t adapt to restriction, so if this approach makes you miserable, it might not be the best option for you. 

Mediterranean Diet 

Characterized by a high intake of fruits, vegetables, olive oil, and fish, and other proteins, the Mediterranean diet is associated with reduced risks of chronic conditions and extended lifespan. Rich in antioxidants, healthy fats, and anti-inflammatory compounds, this diet aligns well with many of the metabolic benefits that metformin provides.

Physical Activity  

Regular physical activity is one of the most effective interventions for healthy aging. Exercise improves insulin sensitivity, reduces inflammation, and enhances cardiovascular and brain health. The protective effects of exercise against chronic diseases like heart disease, diabetes, and dementia make it a cornerstone of longevity-focused lifestyle. 

Moderate Alcohol Consumption   

While excessive alcohol consumption is detrimental to health, moderate intake, particularly of red wine, has been linked to longevity. Red wine contains resveratrol, a compound known for its potential anti-aging properties. It's worth noting that moderation is key, and alcohol consumption isn't suitable for everyone. 

Stress Management 

Chronic stress accelerates aging by exacerbating oxidative stress, inflammation, and hormonal imbalances. Interventions like mindfulness meditation, deep-breathing exercises, and yoga have been shown to reduce stress, improve psychological well-being, and might have positive implications for lifespan. 

Social Connections 

Social isolation has been likened to smoking in terms of its detrimental effects on health and longevity. On the other hand, strong social connections, community involvement, and positive interpersonal relationships contribute to psychological well-being and have been associated with longer, healthier lives. 

Adequate Sleep 

Sleep is a foundational pillar of health and longevity. Chronic sleep deprivation is linked to metabolic disturbances, cognitive decline, increased inflammation, and reduced immune function. Prioritizing 7-9 hours of quality sleep nightly supports the body's repair processes and could play a role in extending healthspan. 

Avoidance of Smoking and Excess Alcohol 

It's well-documented that smoking drastically reduces lifespan and increases the risk of numerous diseases. Similarly, while moderate alcohol might have benefits, excessive consumption poses serious health risks. Abstaining from smoking and moderating alcohol intake are fundamental for those aiming for a long, healthy life. 

Lifelong Learning and Mental Stimulation  

Activities that challenge the brain, like reading, solving puzzles, or learning new skills, can keep cognitive functions sharp. There's evidence suggesting that maintaining mental agility can stave off cognitive decline and potentially extend life. 


Harnessing natural solutions offers an exciting frontier in the journey to better metabolic health. Beyond pharmaceutical interventions like metformin, the earth bestows a plethora of compounds, from berberine to quercetin, that hold the promise of mirroring metformin’s mechanism and amplifying healthy metabolism.
