Synthetic vs Natural

Guanjie produces natural resveratrol powder. Currently there are two main ways to obtain resveratrol, pure natural extraction and chemical synthesis. So what is the difference between natural resveratrol and synthetic resveratrol?

Polygonum Cuspidatum Extract

● Edibility

High-purity natural resveratrol is extracted in a complex way with many processes, but its nutritional value is extremely high and it has a variety of effects on human health and wellness. Synthetic resveratrol, which is synthesized using chemical methods, has a lower nutritional value but cannot be consumed as a health product or dietary supplement.

● Price distinction

Since the extraction of natural resveratrol with high purity requires a lot of labor and time, the price of natural resveratrol is naturally higher in the market. However, if the resveratrol is suitable for chemical synthesis, its manufacturing process is obtained through chemical reagent blending reaction. Therefore, the price is also cheaper.

● Effects on the human body

Polygonum Cuspidatum Extract Powder exerts its effects on a cellular basis. When natural resveratrol acts on the human body, it has a positive effect in general. It also has multiple beneficial effects, making it a highly valued health product. Synthetic resveratrol, on the other hand, is more stable and can act on the body, but it has adverse effects on the body and can even have the opposite effect of natural resveratrol.

Dosage:

The appropriate dosage may vary depending on various factors such as age, health condition and purpose of use. However, a general guideline suggests a dosage of 500-1500 mg per day for adults.

Application:

Polygonum cuspidatum extract powder is widely used in the food and cosmetics industry due to its many potential health benefits.

● Cosmetic grade

One of the most popular applications of Polygonum cuspidatum bulk extract powder is in skincare products. This plant extract is rich in resveratrol, a type of polyphenol that has been shown to have antioxidant and anti-inflammatory properties. These properties help protect the skin against environmental stressors, including pollution, UV radiation, and free radicals, which can cause premature aging and skin damage.

When applied topically, Polydatin powder can help improve the appearance of fine lines, wrinkles, and other signs of aging by promoting collagen production. Collagen is a protein that gives the skin its elasticity and firmness, but it naturally decreases as we age. By boosting collagen production, Resveratrol powder can help improve the skin's texture and reduce the appearance of wrinkles.

In addition to its anti-aging benefits, it also has anti-inflammatory and antimicrobial properties that can help soothe irritated or acne-prone skin. It can help calm redness, reduce inflammation, and clear blemishes, making it a popular ingredient in acne-fighting skincare products.

● Food grade

In addition to its use in skincare products, it is also commonly used as a natural food additive or ingredient in dietary supplements. This plant extract is particularly rich in resveratrol, a powerful antioxidant that has been shown to have myriad health benefits.

One of the most well-known benefits of resveratrol is its potential to promote cardiovascular health. Research has shown that resveratrol can help improve cholesterol levels by reducing LDL (low-density lipoprotein, or "bad") cholesterol and increasing HDL (high-density cholesterol, or "good") cholesterol. It can also help reduce inflammation in the body, which is a key factor in heart disease.
