What is synthetic resveratrol 99%?
Here I am not to inform you of what resveratrol is. I am telling you what synthetic resveratrol is. There are many resveratrol sources to choose from on the market, both synthetic and naturally occurring in dietary supplements and beverages. Natural resveratrol is extracted from Japanese knotweed root, a unique plant native to China with Latin name polygonum cuspidatum. Of course red wine contains resveratrol, The first and most commonly known source is red wine; however, the resveratrol comes from the grapes used to make the wine, contains very low resveratrol and it is relatively expensive comparied with sources from polygonum cuspidatum and other plant sources.

The popular specifications of natural resveratrol are 50% resveratrol and 98% resveratrol while grape source is only 1%, 5% or 10%. There are almost no grape extract resveratrol in China due to high cost and low demand. Many people new to resveratrol may wonder “what’s the rest of the 50% and 2% of resveratrol extract?” Our synthetic resveratrol is the purest form of trans-resveratrol in the world with purity of resveratrol more than 99%.

Why synthetic resveratrol is more popular than natural resveratrol?
Of course, many of you may say that synthetic resveratrol is more potent since it is with higher assay of resveratrol, but is not all. There are cost concern, quality concern, and safe concern.

Cost comparison of fermented resveratrol and natural resveratrol
The natural extracted resveratrol 98% from Japanese knotweed root is about USD260/KG to USD280/KG in general. The price from trading companies and suppliers will be even much higher. While synthetic resveratrol is 99% pure, and the cost is below USD230/KG. There is huge advantage of the fermented resveratrol over the polygonum cuspidatum source. Many nutritional manufacturers want to make their finished supplements competitive in price; they have to cut down the raw material cost by using cheaper source of resveratrol, and the synthetic one is an option.

Quality comparison of synthetic resveratrol and natural resveratrol
There is a problem with natural resveratrol at present. Many Chinese suppliers and manufacturers in order to make their herbal products competitive, and they add synthetic resveratrol into the natural resveratrol and sold as 100% natural resveratrol. Some even sell synthetic resveratrol to buyers as “natural”. This is a kind of adulteration for natural resveratrol. Adulteration is a common phenomenon in herbal supplements. There is a major problem in the global herb and dietary supplement industry in which there appears to be a persistent availability of adulterated herbs, herbal extracts, essential oils and other plant-derived dietary ingredients. Adulteration of botanical ingredients is as old as the herb and spice trade. When buyers create very flexible or weak quality specification requirements, and demand low prices at the same time, they help create a market for adulterated ingredients. Resveratrol is the case. You need to be aware of adulteration when buying natural raw resveratrol ingredient. Of course, you have no worry in buying the synthetic resveratrol. Of course, if you need natural resveratrol 98%, we are able to offer you genuine botanical source.

In addition, synthetic resveratrol is 99% pure, no other ingredients or compounds in it. In natural resveratrol extract, there is abundance of stilbenes, quinines, Anthraquinones, piceids, emodin, and other ingredients. Emodin, according to Wikipedia, is a laxative and can cause diarrhea in high doses. Emodin is what nutritional manufactures do not expect. Natural resveratrol have no such issues.

Standardized extract of resveratrol is subject to seasonal and batch-to-batch variations. The quality of natural resveratrol can be difficult to control, and a significant portion of the extract composition remains entirely uncharacterized. A highly purified, well-characterized Resveratrol is the gold standard used in the most reputable scientific studies that have demonstrated the health benefits of this ingredient.

Herb Nutritionals’ resveratrol is manufactured with a unique and patented fermentation process resulting in a product with over 99% purity and of uncompromised quality.

Safe concern of synthetic resveratrol

Synthetic resveratrol is widely used in bars and beverages, in nutrition supplements, alone or in combination with vitamins and minerals.
