What Is Polygonum Cuspidatum Extract Powder?

This very strong plant-based substance comes from the dried root and stem of Giant Knotweed. It is the best natural source of Trans-Resveratrol in the pharmaceutical and nutraceutical industries around the world.

The extract solves important problems by giving bioactive compounds that are standardized and concentrated. You won't have to deal with the bad profiles and low bioavailability that come with raw herbal materials.

Our formula provides Resveratrol that does not contain Emodin. This gets rid of the laxative effects that come with using crude preparations, making it perfect for medical and beauty uses that need high cleanliness.

Applications Across Industries

Nutraceutical & Dietary Supplements

Your clients want strong anti-aging products. Our Polygonum Cuspidatum Extract Powder turns on SIRT1 genes that make you live longer and protects your heart by stopping LDL oxidation.

It's clear that the extract works well with lipid carriers in softgel forms. This stops the crystals from recrystallizing and increases absorption, which solves the problem of raw stilbenes not being bioavailable.

Our consistent particle size distribution is good for hard capsule formulations. The doses are all the same, and the dissolution profiles are accurate.

Cosmeceutical Formulations

When applied directly to the face, our white powder variant works better at brightening it. It stops tyrosinase activity better than a lot of synthetic alternatives.

Your creams that fight age get much better at reducing oxidative stress. Because the extract is stable, it keeps white cream bases from turning colours over time.

UV-repair serums use the extract's ability to block UV rays. It mixes easily with complicated water-oil mixtures and doesn't change the look or feel.

Functional Drinks and Foods

People want clean labels, and natural preserving meets that need. Our extract is antimicrobial, which means it can kill germs and fungi without adding any artificial ingredients.

We help with the technical side of nano-encapsulation or cyclodextrin inclusion complexes for use in drinks. Because these don't react with water, they make sure that the particles are spread out evenly.

The extract is stable at high temperatures, which is good for adding to snacks and health bars. It stays active at temperatures normal for processing food.

Nutrition and Performance in Sports

Athletes need better oxygen delivery to muscles and blood flow. By improving capillary function, the extract lessens the tiredness that comes from exercise.

Recovery formulas use its ability to reduce inflammation. You can make sports nutrition items that cover a wide range of performance factors.

The format that works with freeze-drying keeps the bioactivity. This makes sure that your sports supplements always work the same way.

Packaging & Storage

We can package your items in a variety of ways, including 1 kg, 5 kg, 10 kg, or 25 kg aluminium foil bags inside fibre bins. You can get packaging solutions that are made just for your needs.

Keep away from bright light and keep cool and dry. If you store it right, it will stay effective for 24 months from the date it was made.
