At this point, most people know that there are microplastics in them, especially in their brains and stomach. But, what harm can they cause? Although the research is still emerging, there’s plenty of data to suggest that microplastics affect energy levels. Specifically, microplastics affect energy levels by disrupting how your body manages, stores, and generates energy by interfering with mitochondrial function, altering metabolism, and inducing oxidative stress. This article breaks down how microplastics affect energy levels at the cellular level, ultimately lowering your energy levels. 

How Microplastics Affect Energy Levels – Metabolic Disruption

Energy homeostasis, the balance between energy intake and energy expenditure, is tightly regulated by metabolic pathways. Many studies have shown that microplastics disrupt these pathways at multiple levels [1]. In animal models, microplastic exposure leads to reduced body and liver weight, irregular lipid metabolism, and impaired hepatic energy processing [1]. These effects point to a direct interference with the body’s ability to manage energy stores.

Microplastics have been shown to alter glycolytic and lipid metabolic gene expression, causing a shift toward anaerobic energy production, as evidenced by elevated lactate dehydrogenase activity and reduced ATP synthesis [1, 4]. This shift suggests a metabolic inefficiency and energy deficits at the cellular level. In zebrafish and other aquatic organisms, microplastics have been shown to disrupt carbohydrate, amino acid, and energy metabolism pathways, reducing overall metabolic adaptability [5].

Additionally, studies have shown that aged polypropylene microplastics further exacerbate the effects, elevating lactate and Fgf21 while reducing pyruvate. Both of these effects are signs of reductive stress and NADH imbalance [6]. These bioenergetic shifts are associated with decreased weight gain and systemic metabolic dysregulation. In parallel, microplastics can induce “food dilution,” reducing caloric and nutrient density by physically occupying digestive space with non-nutritive material [7].

How Microplastics Cause Mitochondrial Dysfunction

The mitochondria, your cells’ power generators, are highly sensitive to microplastic exposure. After being exposed to microplastics and nanoplastics, mitochondria have shown damaged membranes and decreased membrane potential [1, 8]. Since membrane potential drives oxidative phosphorylation, these disruptions mean compromised ATP output and impaired energy storage [8].

Nanoplastics are particularly potent in disrupting mitochondrial structure, leading to swelling, leakage, and ultimately, organelle failure [8]. In mouse Leydig cells, this damage impairs energy production and also hormone regulation [10]. Aged microplastics accelerate this damage by increasing the formation of micro- and nanoscale debris, which trigger NADH/NAD+ imbalance and further disrupt energy transfer within mitochondria [6].

Mitochondrial kinetic homeostasis also declines in the presence of microplastics, reducing the flexibility and responsiveness of energy supply chains at the subcellular level [11].

Oxidative Stress: A Hidden Energy Drain

Microplastic exposure is a well-documented trigger for oxidative stress, a state where the production of reactive oxygen species (ROS) overwhelms antioxidant defenses [12]. This state depletes the cellular machinery needed for efficient energy metabolism.

ROS have been shown to damage DNA, proteins, and lipid membranes, including mitochondrial membranes, further compromising ATP generation [8, 12]. Microplastics amplify this stress via both direct ROS production and immune activation, which raises intracellular oxidant levels [2, 12]. 

Downregulation of antioxidant enzymes, such as superoxide dismutase and catalase, has been observed in microplastic-exposed cells, tilting the redox balance toward dysfunction [15]. The accumulation of ROS may also activate inflammatory complexes like the NLRP3 inflammasome, further interfering with energy-regulating pathways [13, 14].

Additional Variables That Influence Energy Impact

Several variables influence how much microplastics affect cellular energy. These include the particle size and charge, shape, concentration within specific cells and tissues, the duration of exposure, whether or not they particles induce autophagy, and the chemical composition of the particles. [1,8,14,17]. 

Microplastics Affect Energy Processes

There is evidence to show that microplastics do more than accumulate in our bodies, they drain our cells of energy. By disturbing mitochondrial function, warping redox balance, and disrupting nutrient metabolism, microplastic affect energy within our cells. Therefore, for individuals looking to maximize their energy, it’s critical to develop and implement tactics to avoid microplastics. 

While it’s extremely difficult, if not impossible, to avoid microplastics, there are many small, simple actions that you can take each day to lower the amount of microplastics you consume. This is why we developed the Deplasto platform. 

Our platform, consisting of a wellness supplement, an app for measuring daily microplastic intake, and lifestyle recommendations is intended to help you avoid microplastics. Our supplement is formulated to support your body’s natural detoxification defenses, including oxidative stress management, cellular repair, and antioxidant support. Our microplastic intake app is designed to show you an estimate of your daily exposure, with every datapoint backed by scientific studies, to help you understand how you can best avoid microplastics. Lastly, given that it’s nearly impossible to completely avoid microplastic exposure, we have a plethora of lifestyle recommendations designed to help you make small changes for big impacts. 

Overall, we believe that the best way to eliminate microplastics begins with you and the changes you make to your daily life. Over time, collectively, we can make a significant difference in your health and the environment.
