Numerical efficacy endpoints were formally tested for significance between groups by analysis of covariance (ANCOVA). The dependent variable was the value at end-of-study (day 60); the factor was the product group, and the value at baseline (day 0) was the covariate. When the omnibus ANCOVA and ANOVA p-values suggested at least one mean difference was present, pairwise comparisons using the Tukey-Kramer procedure were run. Significant efficacy of NRPT, relative to placebo, was inferred if the pairwise comparisons were significantly different from zero ( p ≤ 0.05). Intractably non-normal data was formally tested for Some supplements are labeled with “trans-pterostilbene” rather than just “pterostilbene.” This compound actually has many names, one of which is trans-3,5-dimethoxy-4′-hydroxystilbene [ 8]. Vascular endothelial cell (VEC) apoptosis is considered to be a primary event which occurs during the formation of atherosclerosis. Two different studies involving mice and mice brain cultures suggest that this stilbene compound might help to reduce damage: Pterostilbene’s most promising application against cancer may be in combination with other substances. Two cell studies have identified strong interactions between pterostilbene and two other drugs: sertraline (an antidepressant under investigation as a brain cancer drug) and gefitinib [ 13, 52].
pTeroPure is the proprietary synthesized form owned by ChromaDex. They do not sell the product to consumers but rather, they sell the ingredient to supplement manufacturers. The photos you see on the right are from a study the University of Wisconsin has been running since 1989 and those photos were taken in 2009.

Also in the hippocampus, pterostilbene increases a protein called Nrf2, which in turn increases the expression of antioxidant proteins [ 25]. Pulmonary heart disease, or cor pulmonale, is a condition wherein the right side of the heart is enlarged, resulting in an abnormal heartbeat, wheezing, discolored skin, and other symptoms. The body of research on pterostilbene is much smaller than on resveratrol, even though pterostilbene is likely to be much more potent and bioavailable. The first thing that comes to your mind as to why that is probably involves the science and it not being up to par. In some regards, that’s a correct assumption to make. We are dedicated to providing the most scientifically valid, unbiased, and comprehensive information on any given topic.
In one rat study, pterostilbene restored normal antioxidant balance and reduced symptoms of cor pulmonale in the heart. A cell study supported these findings: heart cells and tissues exposed to pterostilbene had an improved antioxidant response in the face of oxidative damage [ 40, 41]. Unlike most other vitamins and minerals, where the quality can differ dramatically among brands, the decision here is fairly straightforward. Pterostilbene for sale, regardless of which brand you’re referencing, is almost certainly getting their active ingredient from the same supplier. Pterostilbene may interact with some medications, including anticoagulants, antiplatelet drugs, and drugs metabolized by the liver. It is important to talk to your healthcare provider before taking pterostilbene supplements if you are taking any medications. Allergic reactions Pterostilbene is chemically and structurally related to resveratrol and quercetin. Despite being a structural analog of resveratrol and having structural similarities with quercetin, pterostilbene is touted to be more efficient due to its superior chemical properties. In combination, pterostilbene, resveratrol, pterostilbene, and quercetin are shown to produce more potent health effects experimentally. Further research is needed to explore the therapeutic range of pterostilbene. How does pterostilbene work?Researchers have studied pterostilbene’s ability to fight breast, esophageal, stomach, colon, pancreatic, prostate, blood, lung, and skin cancer cells. It has become a hot topic of cancer research in recent years [ 1, 47, 48]. R esearchers are actively investigating the potential connection between pterostilbene and lon gevity . Pterostilbene has been found to have anti-aging effects by combating oxidative stress, promoting optimal mitochondrial functions, and supporting growth of new mitochondria. This ensures that cells have sufficient energy stores to maintain cellular processes during healthy aging. Pterostilbene may also improve cellular stress resistance, which can promote long-term longevity. Fights infections This same rat study found that pterostilbene was a more powerful antioxidant than its close relative resveratrol. Multiple studies have confirmed that pterostilbene protects against oxidative stress in brain cells [ 23, 25]. So the same two basic facts about quercetin and pterostilbene prevent you from getting sufficient amounts: Whatever the case, you should speak with your doctor before taking a pterostilbene supplement or any other dietary supplement for that matter. Safety should not be assumed just because something is sold over the counter. Miracle or hoax?
Strangely, despite decreasing endoplasmic reticulum stress in the blood vessel lining, pterostilbene actually increases ER stress in throat cancer cells. It may protect healthy cells and selectively damage cancerous cells [ 59]. Apart from its antioxidant and anti-inflammatory properties, pterostilbene has been studied for several other potential health benefits. Supports cognitive health
Pterostilbene health benefits
In a cell study, pterostilbene also protected neurons against a specific type of damage associated with Alzheimer’s disease [ 29]. 3) Blood Sugar One way you can get the most out of Quercetin and Pterostilbene Advanced is by combining it with one or more of our other formulas: Combining pterostilbene with caffeine creates a pterostilbene-caffeine hybrid, which may lead to a slower absorption rate of caffeine, thereby reducing the associated "caffeine crash" symptoms.
