About BulkActives' Resveratrol
About Resveratrol
"Resveratrol (3,4′,5-trihydroxystilbene) is a polyphenolic phytoalexin compound present in the skin and seeds of grapes, berries, peanuts, and other foods. The preponderance of data on resveratrol is very recent, with increased research activity following a seminal report in the journal Science in 1997 (Science 1997;275:218–20; Biochem. Biophys. Res. Commun. 2005;331:993–1000; Cancer Res. 2001;61:1604–10).
In the 1997 study, purified resveratrol was found to exhibit major inhibitory activity against cancer initiation, promotion, and progression. Specifically, its antioxidant and antimutagenic potency and induction of phase II drug-metabolizing enzymes were seen as counter to carcinogenic initiation. Resveratrol hindered cyclooxygenase and hydroperoxidase and initiated anti-inflammatory effects, thereby demonstrating antipromotion activity. The induction of human promyelocytic leukemia cell differentiation by this newly discovered botanical ingredient also thwarted the progress of carcinogenic activity. In addition, resveratrol demonstrated significant inhibitory effects in vitro with carcinogen-induced preneoplastic lesions in mouse mammary glands, and in vivo with tumorigenesis in the two-stage mouse skin cancer model (Science 1997;275:218–20).
Since then, copious research has been performed on this compound, which has developed a strong reputation as a potent antioxidant, anti-inflammatory, and antiproliferative agent (Toxicol. Appl. Pharmacol. 2003;186:28–37; Biochem. Pharmacol. 2002;63:99–104; Biomed. Papers 2003;147:137–45). Most importantly, it is considered to act as a chemopreventive agent against skin cancer and to exert an antiproliferative influence on oral-squamous, breast, colon, and prostate cancer cells, in which it triggers apoptosis (Pancreas 2002;25:e71–6; J. Biol. Chem. 2003;278:41482–90). Research has confirmed its inhibitory effects on tumor initiation, promotion, and progression (Biomed. Papers 2003;147:137–45; Front. Biosci. 2002;7:784–92; Skin Pharmacol. Appl. Skin Physiol. 2002;15:297–306).
The most recent data indicate that resveratrol protects against UVB-mediated cutaneous damage in SKH-1 hairless mice, particularly by inhibiting survivin, the overexpression of which is associated with various cancers (Photochem. Photobiol. 2005;81:25–31; FASEB J. 2005;19:1193–5)." BAUMANN LS, Skin & Allergy News- 2006 06 (Vol. 37, Issue 6)
Resveratrol 98% is used in many home made skin care recipes. It is useful as an antioxidant, an anti-inflammatory, for skin lightening & brightening, and for sun damage repair. Resveratol is a natural ingredient that can be found in many plants. The product we sell comes from Giant Knotweed.

"Both Japanese knotweed and giant knotweed are important concentrated sources of resveratrol, replacing grape byproducts. Many large supplement sources of Resveratrol now use Japanese knotweed and use its scientific name in the supplement labels." Read more
Our Resveratrol is extracted from the roots of the Giant Knotweed, and is standardized at 98%
"Resveratrol is produced by several plants, apparently for its antifungal properties. It is found in widely varying amounts in grapes (primarily the skins), raspberries, mulberries, in peanuts, berries of Vaccinium species, including blueberries, bilberries, and cranberries, some pines, such as Scots pine and eastern white pine, and the roots and stalks of giant knotweed and Japanese knotweed, called hu zhang in China. Resveratrol was first isolated from an extract of the Peruvian legume Cassia quinquangulata in 1974." Read more
