Resveratrol Powder

Resveratrol Powder Suppliers​

Resveratrol is a natural polyphenol compound mainly extracted from plants such as Polygonum cuspidatum, grape skins and seeds, and peanuts. It has potential antioxidant, anti-inflammatory, and cardiovascular protective effects, helps to eliminate free radicals, delay cell aging, and may be beneficial in cancer prevention. It is commonly found in health supplements and skincare products.

Resveratrol is a popular product of Healthkintai^®. Kintai is a leading plant extract manufacturer and supplier in China. Our98% Resveratrol comes from Polygonum cuspidatum, as well as chemically synthesized resveratrol. Please feel free to contact us at info@kintaibio.com if you have any needs.

Physical and Chemical Properties of Resveratrol

Trans Resveratrol vs Resveratrol​

Resveratrol is a general term for this type of polyphenol compound, which naturally exists in two geometric isomers: trans- and cis-. The core difference between the two lies in the configuration of the double bonds in their molecules, which directly determines their biological activity.

Trans-Resveratrol is the predominant form found in nature and is the active ingredient whose potent antioxidant, anti-inflammatory, cardiovascular, and neuroprotective effects have been confirmed by almost all scientific studies. Cis-Resveratrol, on the other hand, has very weak biological activity and is usually formed from the trans isomer under light or heat. Therefore, the efficacy of commercially available supplements and skincare products highly depends on the purity and stability of their trans-resveratrol.

In short, "resveratrol" is a general term, and its effectiveness hinges on the content of highly active trans-resveratrol. When purchasing, prioritize products that clearly label themselves as trans-Resveratrol and of high purity. Kintai's polygonum cuspidatum extract resveratrol, rich in trans-resveratrol, is your best choice.

Benefits of Resveratrol Powder

1.Resveratrol Antioxidant&Anti-inflammatory Properties

Resveratrol's chemical structure makes it a potent antioxidant, directly scavenging free radicals and protecting cells from oxidative damage. More importantly, it activates longevity protein pathways such as SIRT1 and inhibits key inflammatory signaling such as NF-κB, downregulating the expression of various pro-inflammatory factors at the gene level. This ability to alleviate chronic low-grade inflammation at its root is considered a common mechanism for preventing various chronic diseases, building a fundamental defense for overall health.

2.Resveratrol Cardiovascular Protection

Resveratrol has multiple protective effects on the heart and blood vessels. It improves vascular endothelial function, promotes nitric oxide release, helps dilate blood vessels, and lowers blood pressure; it inhibits the oxidation of "bad cholesterol" (LDL), slowing the formation of atherosclerotic plaques; and it also has an anti-platelet aggregation effect, reducing the risk of thrombosis. These synergistic effects make it a potential cardiovascular health support ingredient.

3. Resveratrol for Neuroprotection

Resveratrol can cross the blood-brain barrier and act directly on the central nervous system. Its antioxidant and anti-inflammatory properties help protect neurons. Studies show that it can reduce the toxic accumulation of β-amyloid protein (associated with Alzheimer's disease) and may promote new neuronal connections in the hippocampus. It is also believed to enhance brain cell resistance to stress and mitochondrial function by activating the SIRT1 pathway, offering hope for combating neurodegenerative diseases and cognitive decline.

4.Resveratrol for Skin

Resveratrol exhibits numerous positive effects on skin health, making it a highly sought-after active ingredient in skincare products. Its core function stems from its powerful antioxidant capacity, effectively neutralizing free radicals generated by environmental stressors such as UV rays and pollution，thus preventing photoaging and delaying the appearance of wrinkles and sagging.

Simultaneously, it possesses significant anti-inflammatory properties, helping to soothe sensitive skin, reduce redness and swelling, and combat skin problems exacerbated by inflammation (such as acne). Studies have also shown that resveratrol can enhance cellular repair and defense mechanisms by activating the longevity protein SIRT1 in skin cells, promoting vitality.

Uses of Resveratrol Powder

1. Resveratrol Supplements

This is resveratrol's most important and mature application area. Based on its antioxidant, anti-inflammatory, and potential cardiovascular protective effects, resveratrol is widely formulated into capsules, tablets, or liquid supplements for daily consumption to maintain health and delay aging. In addition, it is also added as a functional ingredient to beverages (such as wine-flavored drinks), chocolate, and healthy snacks to enhance product value, emphasizing "antioxidant" and "health maintenance" concepts.

2. Resveratrol for Skincare and Cosmetics

Resveratrol's excellent antioxidant and anti-inflammatory properties make it a star ingredient in skincare products. It is used in serums, creams, lotions, and other products, with main functions including: combating photoaging, neutralizing free radicals, and reducing UV damage; brightening skin tone and inhibiting melanin production; soothing and reducing skin inflammation; and promoting repair and activating skin cell vitality. Its synergistic effect with ingredients such as vitamins C and E is often used to build highly effective anti-aging skincare systems.

3. Animal Nutrition and Farming

This application reflects its economic value. In livestock and aquaculture, resveratrol is used as a green feed additive. Its main purposes are: to improve animal disease resistance, reduce intestinal diseases in farmed animals by utilizing its anti-inflammatory properties; to improve meat quality and antioxidant status, exerting antioxidant effects in the animal body, potentially extending the shelf life and nutritional value of meat; and as a potential antibiotic alternative, serving the growing trend towards healthy farming and food safety.​​​​​​​

FAQ

Q1:Who should avoid resveratrol?

A1:Certain individuals should exercise caution or avoid resveratrol supplements. These include: pregnant or breastfeeding women (due to lack of safety data); people with hormone-sensitive conditions (e.g., certain breast, ovarian, or uterine cancers), as resveratrol may have estrogenic effects; those scheduled for surgery or on anticoagulant/antiplatelet drugs (like warfarin or aspirin), due to increased bleeding risk; and individuals taking medications metabolized by the liver enzyme CYP3A4 (e.g., some statins, calcium channel blockers), as resveratrol may alter their blood levels. Consulting a doctor before use is essential.

Q2:Why use resveratrol at night?

A2:The recommendation to take resveratrol at night is based on two primary biological rationales, though direct human clinical evidence is still emerging.First, it aligns with the body's natural circadian rhythm for repair. Key processes like DNA repair, cellular cleanup (autophagy), and the activity of its target protein, SIRT1, are often heightened during sleep and nighttime fasting. Second, from a practical standpoint, taking a supplement at a consistent time (like bedtime) can improve adherence.
