RESVERATROL

What is Polygonum Cuspidatum Extract Resveratrol?

Polygonum Cuspidatum Extract Resveratrol has two structures, cis and trans. It mainly exists in trans conformation in nature. The two structures can be combined with glucose to form cis and trans-resveratrol glycosides. The cis- and trans-resveratrol bulk powder can release resveratrol under the action of glycosidases in the gut. Under UV light irradiation, trans-resveratrol can be converted to the cis-isomer.

Polygonum cuspidatum resveratrol is our most powerful product. We have four resveratrol products,Revsratol ,Granualr Resveratrol ,micronized resveratrol, Liposome Resveratrol and water-soluble resveratrol. We can make Micronized Resveratrol be micronized to<3μm (D50), even <5μm (D90). It is micronized by a machine named the high-frequency vibration machine, which is used to grind gunpowder for the war industry. And water-soluble resveratrol uses Hydroxypropyl-β-Cyclodextrin to embed resveratrol. The assay of water-soluble resveratrol is about 10%. It is fit for making melting tablets.

Advantages of Resveratrol ,Micronized Resveratrol, Granular Resveratol Liposome Resveratrol And Water Soluble Resveratrol:

1,Resveratrol

We have different specification of Reveratrol from 10% to 98%, each specification has a large stock and welcome to inquiry. we have own GPM palnting base of polygonum cuspidatum,our factory has good mature technical of producing resveratrol for over 13years. all the goods have a good feedback from our customer.we can customized capsule

and tablets to our customer.

2.Customized Micronized Resveratrol

The most power technique for our resveratrol is Micronized Resveratrol Powder. We can make it to micronized to<3μm (D50).It is micronized by amachine named-high-frequency vibration machine,which is used for grind gun powder for the war industry. Usually, most of high purity ingredientfrom herbs can be micronized easily, some kind of ingredient can be micronized to <5um (D90), such as resveratrol, but if you do Particles sizeanalysis,the data is not good, some Particles has static electricity, and they come together again, but we can test by electron microscope again.

3.Granular Resveratrol

Granular Resveratol specification is 98%, the particle size is 20mesh , the advantage is soveing the low density,grain weight while filling in capsules,.about the mesh, we can sutomized as your requierment.

4.Liposome Resveratrol

Liposome Revsratrol is one of our advanced product, Liposome Resveratrol refers to a form of resveratrol, This formulation enhances the bioavailability and absorption of resveratrol in the body, as the liposomes protect the compound from degradation and facilitate its transport through cell membranes.

5.Water-Soluble Resveratrol

The water soluble resveratrol specification is 10%,Water-Soluble Resveratrol refers to a modified form of resveratrol that has been specially processed or formulated to dissolve in water, as opposed to the typical fat-soluble version.To overcome this challenge, water-soluble resveratrol is created through various techniques, such as complexing it with cyclodextrins, nanoencapsulation, or using other solubilizing agents. These methods enhance the compound's bioavailability, allowing for more efficient absorption in the digestive tract and increased delivery to tissues where it can exert its beneficial effects.
