What Is Pterostilbene? Benefits, Risks, and How It Compares to Resveratrol

You may have heard about resveratrol—the antioxidant compound found in red wine and grapes that’s often associated with heart health and anti-aging. But there’s another compound quietly gaining attention in health and longevity circles: pterostilbene (pronounced tero-still-bean). It’s a natural compound similar to resveratrol but believed by some researchers to be more potent and effective, especially when it comes to fighting inflammation, boosting brain health, and slowing aging.

So what is pterostilbene, really? And is it something worth paying attention to—or even supplementing with?

In this article, we’ll break it all down in plain, simple terms. You’ll learn what pterostilbene is, where it comes from, how it works in your body, its benefits, its risks, how it compares to resveratrol, and whether or not it’s worth trying. Let’s dive in.

What Is Pterostilbene, Really?

Pterostilbene is a natural antioxidant compound found in small amounts in blueberries, grapes, and even the heartwood of trees like Indian kino and red sandalwood. It’s part of a group of compounds called stilbenes, which are known for their protective effects against stress, inflammation, and aging.

If the name reminds you of “resveratrol,” that’s because they’re chemical cousins. In fact, pterostilbene is structurally similar to resveratrol, just with a few small differences that make it more fat-soluble, more absorbable, and possibly more long-lasting in your body. Scientists say that because of these changes, pterostilbene may be four times more bioavailable than resveratrol, meaning your body can use it more efficiently.

While pterostilbene occurs naturally in some foods, the amounts are pretty tiny. A cup of blueberries may contain only a few micrograms. That’s why, if people are trying to get measurable health effects, they usually turn to supplements, where the dose is much higher and standardized.

What Makes Pterostilbene So Special?

To understand why pterostilbene is getting so much attention, it helps to look at what antioxidants actually do. Every day, your body deals with damage from things like pollution, stress, processed food, or even normal aging. This damage is often caused by unstable molecules called free radicals, which can harm cells, proteins, and even your DNA.

Antioxidants like pterostilbene help fight this damage by neutralizing free radicals. But pterostilbene doesn’t stop there. Research has shown that it may also help regulate inflammation, support brain function, protect against age-related decline, and more. It works in multiple ways, and that’s part of what makes it so promising.

Let’s look closer at what science says pterostilbene may actually help with.

The Top Health Benefits of Pterostilbene

1. It May Protect Your Brain and Boost Mental Clarity

One of the most exciting benefits of pterostilbene is how it may support brain health—especially as we age. In animal studies, pterostilbene has been shown to improve memory, reduce oxidative stress in the brain, and protect brain cells from damage. Some studies even suggest it may help reduce the risk of neurodegenerative diseases like Alzheimer’s, though more human research is needed.

Pterostilbene’s brain benefits are thought to come from its ability to cross the blood-brain barrier, which many other antioxidants can't easily do. This means it can actually get into the brain and go to work where it’s needed.

It also seems to reduce brain inflammation, which scientists believe is a major cause of cognitive decline and mental fog as we age. By calming inflammation and protecting neurons, pterostilbene may help you stay sharper for longer.

2. It Supports Cellular Health and Longevity

Pterostilbene is also linked to cellular longevity—that is, helping your cells function better for longer periods of time. Research suggests that it can activate certain longevity genes known as sirtuins, especially SIRT1, which play a key role in how our bodies respond to stress, aging, and DNA damage.

Some scientists believe that activating sirtuins may slow aspects of biological aging and improve how our bodies repair themselves. This is part of why pterostilbene is often included in anti-aging supplements and NAD+ booster formulas (like those containing nicotinamide riboside or NMN).

In short, pterostilbene may help protect your cells from stress and extend their lifespan—keeping your tissues and organs healthier for longer.

3. It Helps Fight Inflammation

Chronic inflammation is a silent contributor to many modern health problems—from heart disease to diabetes, obesity, and even cancer. And one of pterostilbene’s best-known effects is its ability to calm inflammation at the cellular level.

Studies have shown that pterostilbene can reduce levels of inflammatory markers in the body, including NF-kB and cytokines like TNF-alpha. While more human studies are needed, these early results suggest that it could be a useful natural tool for managing low-grade inflammation and promoting long-term health.

4. It May Improve Heart and Metabolic Health

There’s also growing evidence that pterostilbene may benefit your heart and metabolism. In some clinical trials, it has been shown to help reduce blood pressure in adults with high blood pressure. It may also help improve cholesterol balance by reducing LDL (bad cholesterol) and raising HDL (good cholesterol), though the effects seem to vary depending on the person and the dosage.

Additionally, pterostilbene has been studied for its potential to support blood sugar balance and insulin sensitivity. That’s important because better metabolic function is closely tied to better overall health and longevity.

5. It Might Have Anti-Cancer Properties

Although it’s still early, some lab studies suggest that pterostilbene may help slow the growth of certain cancer cells, especially in the breast, colon, and pancreas. It appears to do this by reducing oxidative stress, calming inflammation, and influencing gene expression in cancer cells.

However, these studies are preliminary and mostly done in petri dishes or on animals. While promising, it’s too soon to say whether pterostilbene can prevent or treat cancer in humans. Still, it adds to the list of ways this compound may support the body’s natural defenses.

Pterostilbene vs. Resveratrol: What’s the Difference?

Since pterostilbene and resveratrol are closely related, it’s natural to wonder which one is better—or whether you need both.

The main difference comes down to bioavailability. Resveratrol is harder for the body to absorb and breaks down quickly once it’s inside you. Pterostilbene, on the other hand, is more fat-soluble, which helps it stay in the body longer and do its work more effectively.

This makes pterostilbene more potent milligram for milligram. In other words, you may need much less pterostilbene to get similar or better results than you would from resveratrol.

Some experts suggest that while resveratrol is useful for short bursts of antioxidant protection, pterostilbene may be better for long-term support, especially for brain and metabolic health.

And yes, you can take them together. In fact, some supplements stack the two to get the best of both worlds.

Is Pterostilbene Safe?

Overall, pterostilbene appears to be safe for most people when taken at reasonable doses. In clinical trials, people have taken up to 250 mg per day without serious side effects.

That said, some studies have found that very high doses—especially above 250 mg—might raise LDL cholesterol levels in some people. While this hasn’t been a consistent finding across all studies, it’s something to be aware of if you already have cholesterol concerns or take statins.

Other potential side effects are rare but could include stomach upset, dizziness, or headache, especially if taken on an empty stomach or in combination with other supplements.

If you’re pregnant, breastfeeding, or taking medication for blood pressure, cholesterol, or blood sugar, it’s smart to talk to your doctor before adding pterostilbene to your routine.

How to Take Pterostilbene for Best Results

Most people take pterostilbene in capsule form, often as a standalone supplement or combined with other ingredients like NAD+ precursors or resveratrol.

The most common dose range in human studies is 50 to 150 mg per day, though some supplements offer up to 250 mg per capsule.

For best absorption, pterostilbene can be taken with food, especially a meal that contains some healthy fats, since it’s fat-soluble. It’s generally taken once or twice per day, depending on the formula.

If you're new to it, starting with a lower dose and gradually increasing based on how you feel is a safe and reasonable approach.
