For preserving good health and preventing many diseases, anti-inflammatory and antioxidant qualities are essential. Anti-inflammatory traits assist in controlling how the body reacts to injury or illness, minimizing chronic inflammation that can result in dangerous diseases like diabetes and heart disease. Antioxidants, on the other hand, are essential in preventing aging and diseases like cancer by scavenging dangerous free radicals that can harm DNA and cells.

Pterostilbene, found in fruits like blueberries and grapes, is an excellent natural source of these essential properties. Strong anti-inflammatory and antioxidant properties are displayed by pterostilbene. By efficiently scavenging free radicals, it successfully combats oxidative stress, demonstrating its potential to improve overall health and reduce the risk of chronic diseases linked to inflammation and oxidative damage.

What is Pterostilbene?

Pterostilbene, chemically known as 3,5-dimethoxy-4′-hydroxy-trans-stilbene, is a natural dietary compound belonging to the stilbenoid class. It is a dimethyl ether analog of resveratrol, sharing a similar chemical structure with the addition of two methoxy (CH3O) groups and exhibiting better bioavailability. Pterostilbene is found in various plants, particularly in fruits like blueberries, grapes, and almonds. [R] [R] [R]

The pterostilbene molecule can be considered a derivative of resveratrol due to its similar chemical structure, with the only difference being the addition of two methoxy groups that replace hydroxyl groups on the resveratrol. These structural modifications, specifically the presence of methyl groups, can enhance pterostilbene’s bioavailability and metabolic stability compared to the resveratrol molecule. Despite their resemblance, pterostilbene may offer distinct health benefits, potentially being more potent in aspects such as antioxidant and anti-inflammatory effects due to its altered structure. [R]

Pterostilbene is sometimes referred to as a “calorie-restriction mimetic” because of its capacity to activate sirtuin enzymes. Sirtuins are a class of proteins linked to various biological processes, including cellular health, metabolism, and aging. Calorie restriction is known to activate sirtuins, leading to enhanced metabolic efficiency and potentially extending lifespan. Pterostilbene, by activating sirtuin enzymes similarly to how calorie restriction does, may replicate these effects, promoting improved cellular function, and energy metabolism, and potentially contributing to a longer, healthier life. [R] [R]

Pterostilbene is also to trans-pterostilbene. Isomers are chemically similar compounds that differ in structure or spatial orientation. The molecular formulas of pterostilbene and trans-pterostilbene are the same (C16H16O3), but the arrangement of atoms or groups around a double bond alters, resulting in distinct chemical and physical properties. [R]

Potential Benefits of Pterostilbene

Heart Wellness

Pterostilbene may have the potential to support heart health by lowering cholesterol levels, enhancing blood pressure, and avoiding the development of arterial plaque. A lower risk of heart disease is a result of these impacts.  [R]

A 2005 study by Rimando AM and colleagues titled “Pterostilbene, a Dimethyl Ether Derivative of Resveratrol, Reduces Fat Accumulation in Cholesterol-Fed Rats” looked into the impact of pterostilbene on fat storage in rats fed a diet high in cholesterol. The animal studies sought to comprehend the effects of pterostilbene, a substance chemically related to resveratrol, on fat storage. The results demonstrated that pterostilbene had the potential to reduce fat formation, which may have consequences for heart health. This implies that pterostilbene might provide a natural way to treat issues with fat, aiding in the promotion of a healthy cardiovascular system. [R]

Cognitive Ability

The neuroprotective qualities of pterostilbene may lower the risk of cognitive decline and promote brain health. It might improve one’s memory, learning, and general cognitive abilities. [R]

The 2013 study, “Pterostilbene Decreases Alzheimer’s Disease-Related Pathologies in Neurons of Triple Transgenic Mice” by Joseph JA and colleagues, delved into the potential effects of pterostilbene on Alzheimer’s disease-related pathologies in mice. By examining the impact of pterostilbene on neuron health and disease markers, the research revealed promising results, suggesting that pterostilbene could play a positive role in reducing these pathologies. This signifies its potential to support cognitive function, particularly in the context of Alzheimer’s disease. [R]

Anti-cancer Properties

According to research, pterostilbene may prevent the proliferation of cancer cells and trigger apoptosis to have anti-cancer effects. Different types of cancer may be prevented or have their progression slowed by it. [R] [R]

The 2017 study, “Pterostilbene Inhibits Breast Cancer in Vitro through Mitochondrial Depolarization and Induction of Caspase-Dependent Apoptosis” conducted by Kostin SF and team, focused on investigating the potential anticancer properties of pterostilbene specifically against breast cancer cells. The research findings revealed that pterostilbene demonstrated the ability to impede the growth of breast cancer cells and initiate apoptosis, a natural process of programmed cell death. These results suggest that pterostilbene holds promise as a natural anticancer agent, particularly in the context of breast cancer. [R]

Blood Sugar Control

For patients with diabetes or at risk of getting the disease, pterostilbene may help in controlling blood sugar levels and enhancing insulin sensitivity. [R]

Understanding how pterostilbene affects glucose and lipid balance in rats was the main goal of the 2009 study by Rimando AM and colleagues, titled “Pterostilbene, a Natural Analog of Resveratrol, Improves Glucose and Lipid Homeostasis in Rats”. The study’s findings suggested that pterostilbene can improve the regulation of glucose and lipids, indicating its potential for efficiently controlling blood sugar levels and lipid metabolism. This emphasizes the idea that pterostilbene could be a useful natural component in blood sugar management techniques. [R]
