What are the benefits of Pterostilbene Powder?

The active component pterostilbene is present in plant fruits like grapes, bilberries, and blueberries. In plants, it has an anti-toxin function. Pterostilbene is a trans-stilbene molecule that shares structural similarities with resveratrol. It is a methylated derivative of resveratrol. Pterostilbene efficiently raises bioavailability because it has two methoxy groups that facilitate absorption. It possesses a variety of biological properties, including lipid-lowering, antibacterial, anti-tumor, anti-inflammatory, and antioxidant properties. As a result, it is widely employed in many industries, including food, cosmetics, and medicine.

1) Resveratrol and pterostilbene share similar molecular structures and methods of action. Antioxidant resveratrol aids in the defense against damage caused by free radicals. Pterostilbene, which has two methylation derivatives "embedded" in its structure, is a derivative that is more stable, has a better bioavailability, and has a stronger antioxidant impact than resveratrol.

2) Pterostilbene has a higher antifungal action than resveratrol because of its distinct structure. Furthermore, pterostilbene has greater antioxidant and stability in the body than resveratrol.

3) Pterostilbene has two methoxy groups that facilitate absorption, which significantly boosts bioavailability. Its bioavailability in animal tests has been demonstrated to be approximately 80%, whereas that of resveratrol is approximately 20%. Pterostilbene is more soluble in oil thanks to its two methoxy groups, and it dissolves well in polar oils, which makes it a convenient ingredient for oil-phase products.

Benefits to the skin

01 Antioxidant

Pterostilbene powder bulk has strong antioxidant properties. It is the best known plant ingredient for topical skin care products when it comes to antioxidation and whitening.

02 Inhibit tyrosinase

Tyrosinase is the key enzyme in the synthesis of melanin. The half-inhibitory concentration IC50 value of glabridin, known as the "whitening gold", on tyrosinase is the lowest among all products. Pterostilbene is slightly lower than glabridin, but significantly better than other whitening raw materials such as VC and arbutin.

03 Inhibit melanin

It has an extremely potent anti-melanin action, even outperforming "whitening gold" glabridin, and it effectively reduces freckles.

04 Anti-inflammatory

It can inhibit the expression of COX-2, iNOS, PGE2 and NO through the Nrf2 pathway and reduce the degree of inflammation. There are some destructive enzymes in the human body, such as elastase and collagenase, which can destroy the skin structure, causing the skin to sag and age. Pterostilbene has dual inhibitory ability, inhibiting two destructive enzymes at the same time, which can effectively resist wrinkles and delay aging, and improve the situation of loose wrinkles.

05 Anti-ultraviolet

Resist ultraviolet rays and prevent light damage

In the study of "Protective effect of pterostilbene on acute light damage of human fibroblasts caused by long-wave ultraviolet radiation", DNA damage analysis was performed through cell viability detection and comet assay, and it was found that a certain trace concentration of pterostilbene can reduce the damage of ultraviolet rays to HFF cells.

The maximum ultraviolet absorption wavelength of pterostilbene is 306nm, and its absorption peak range covers the 280-320nm band (UVB), with good UVB absorption effect.

06 Anti-glycation

Glycated aging protein (AGE) is the result of free glucose in the body interacting with proteins in a spontaneous way through the Maillard process. Normal protein is destroyed during the creation process of AGE protein, which ends up destroying cell integrity and life. Its polyhydroxyl characteristics enable it to compete with the hydroxyl groups on sugars to produce Schiff bases, preventing the deposition of high molecular weight AGE. It can also efficiently prevent and repair AGE glycated aging proteins.

Health Benefits

01 Support cardiovascular health

Atheroclerosis risk can be decreased by controlling the antioxidant enzyme SOD, vascular endothelial cells, and vascular smooth muscle cells.

02 Support gastrointestinal health

It has a certain inhibitory effect on the growth of harmful cells in the esophagus, stomach and colon, and reduces adverse gastrointestinal inflammatory reactions.

03 Improve carbohydrate metabolism

It moderates unpleasant gastrointestinal inflammatory responses and has a certain inhibitory effect on the proliferation of pathogenic cells in the stomach, colon, and esophagus.

04 Improve fat metabolism

It can decrease fat cell group proliferation and triglyceride buildup in the body in 3T3-L1 preadipocytes.

05 Improve liver health

Blueberry extracts, including pterostilbene, have the ability to upregulate Nrf2 pathways and antioxidant enzyme production. An trial revealed that pterostilbene users had much lower levels of indicators associated with acute liver injury.

06 Delaying brain aging

It can slow down memory and brain deterioration caused by inflammatory reactions, and alleviate brain aging.

07 Cardiovascular care

It can reduce brain aging and inflammation-induced memory loss as well as brain degradation.

08 Liver protection

By altering several antioxidant, anti-inflammatory, and anti-proliferative pathways, pterostilbene can enhance the function of liver cells.

09 Metabolism

Pterostilbene's anti-hyperglycemic and antioxidant properties can help diabetic patients prevent problems by reducing hyperglycemia and the associated damage to their liver and kidneys. By raising antioxidant activity, pterostilbene can enhance glucose metabolism. Additionally, the heightened antioxidant activity it produces may lessen the harm that hyperglycemia's reactive oxygen species-which cause damage to organs-create.

10 Neuroprotection

Aging is closely associated with neurodegenerative disorders, including Parkinson's and Alzheimer's diseases. This results from older people's elevated oxidative stress and declining antioxidant capacity. These illnesses have an aging connection and, once they start, will make aging worse. Antioxidant-rich berries can successfully slow down this neurological degeneration, according to several studies.
