What is Polygonum Cuspidatum Extract Polydatin?

Polydatin, also known as piceid, is a glucoside of resveratrol, which means that the resveratrol is joined to a sugar molecule. It seems that in scientific documentations, scientists prefer to using piceid, while in supplements or daily life, polydatin is more popular. Therefore, we will use polydatin more often in the rest of the article.

Once the polydatin enters the bloodstream the sugar molecule is cleaved off, leaving the resveratrol. This in turn means that the glucoside of resveratrol is absorbed at a different rate to standard trans-resveratrol, thereby effectively increasing the half-life and the potency of the resveratrol.

Health Benefits of Polygonum Cuspidatum Extract Polydatin

1) lipid-lowering and lipid peroxidation

Polydatin can improve lipid membrane stability, significant inhibition of lipid peroxidation effect. Show that regulation of polydatin Hyperlipidemia rat serum lipid metabolism and rectify free radical metabolic disorder, which anti-atherosclerosis effect.

2) on vascular smooth muscle cells in vitro

Polydatin on rat vascular smooth muscle cells and effects of human umbilical arterial smooth muscle cells study: polydatin on intracellular calcium bi-directional regulation of PH value.

3) on myocardial cells in vitro

Reports on the study on myocardial cells in rats showed that cardiotonic effect may be achieved by increasing free calcium ion concentration in single cells and directly enhance myocardial contractility.

4) on platelet aggregation and microcirculation

Studies have found that polydatin in vitro and in vivo inhibition of arachidonic acid, adenosine diphosphate and epinephrine-induced platelet aggregation in rabbits, stronger than aspirin, indicating polydatin antithrombotic role is closely linked to strong anti-platelet aggregation.

5) antioxidant protective effect

Multiple organ failure caused by oxygen free radicals are an important mechanism, polydatin has significant antioxidant protection of the liver, inhibit the accumulation of lipid peroxidation in the liver of a class action.
