What is Blueberry Extract?

Blueberries are grown in Europe, Canada and the U. S. And extracts of the ripe berry are known to contain flavonoid pigments known as anthocyanins - which act as powerful antioxidants.
Modern laboratory studies on pterostilbene have confirmed a number of activities including antioxidant effects, an ability to inhibit aggregation of blood platelets (reduce stickiness, hence a tendency to clotting of blood cells), produce a slight relaxation effect on vascular smooth muscles, and a possible role in reducing factors associated with chronic inflammatory diseases.

Main Function:


Like resveratrol, it belongs to a class of compounds called phytoalexins, which are naturally produced by plants when under attack by pathogens such as bacteria or fungi, but now it is available by chemical synthesis.


And like resveratrol, there are animal studies showing it's efficacy at improving heart health, most notably by correcting the dyslipidemia that leads to atherosclerosis and coronary heart.
2-4 Pterostilbene is one of several stilbenes found in certain berries (e. G., blueberries, cranberries, sparkleberries, lingonberries, and grapes), thus, consumption of these small fruits may help improve health.

Benefits of Pterostilbene:


Potent Antioxidant

Experiments suggest pterostilbene has several important benefits. First and foremost, the compound acts as a powerful antioxidant. It also appears to bind to PPAR receptors, stimulating production of the compound. PPAR plays an important role regulating cholesterol and lipids in the blood. One study using animal models reported its success promoting normal triglyceride levels. 


Supports Normal Blood Sugar

Numerous studies have found blueberry consumption, particularly pterostilbene ingestion, supports already healthy blood sugar. In one study, 97 adults took a pterostilbene supplement for 12 weeks. At the end of the study, 67% of the participants had normal glucose levels. 


Rejuvenates Brain Cells

The antioxidant and soothing properties of pterostilbene helps brain cell health. Multiple studies have demonstrated pterostilbene supports motor function and cognitive abilities in adults suffering from memory changes. 


Like Red Wine, Pterostilbene Promotes Longevity

Trans-pterostilbene is a bioactive chemical which has been shown to support cognitive health, normal blood sugar, and soothe irritation. In vitro and in vivo studies support pterostilbene's therapeutic effects. The compound also acts as a caloric restrictionmimetic, triggering the human body to release biochemicals such as adiponectin which promotes healing.
