Resveratrol, a primary bioactive ingredient present in two Isagenix products—CytoActives™ and IsaGenesis®—is a fascinating molecule with an equally fascinating history. Even its name is cloaked in mystery with speculation the word derives from the collective of resorcinols, the class of molecules where resveratrol belongs plus veratr, the plant type where it was first isolated, and ol,indicative that the molecule has hydroxyl (alcohol) groups.
The “French Paradox”
Resveratrol was first mentioned in an article published in 1939 by Japanese researcher Michio Takoaka (1). According to varying accounts, experiments on the exotic, but poisonous plant Veratrum grandiflorum allowed researchers to chemically isolate resveratrol. Later in 1963, the molecule was isolated from Polygonum cupsidatum (Japanese knotweed), a common source for traditional Chinese and Japanese medicine. Resveratrol has since been identified in more than 70 different plant species such as grapevines, legumes, and pines (2) with its synthesis increased in response to stressors such as injury, ultraviolet radiation, and fungal infections.
Other dietary sources of resveratrol include chocolate, peanuts, soybeans, pomegranates, and, of course, red grapes, particularly the skin of the grape. Interestingly, since grape skins are not fermented during the production of white wine only red wine contains resveratrol and is indeed the richest source of the substance in most human diets (approximately 0.5-1.0 mg per glass of red wine).
There would be scant scientific interest in resveratrol until 1992 when French scientists Serge Renaud and Michel de Lorgeril concluded from epidemiological data that, despite a diet rich in saturated fat and other poor lifestyle habits (such as a high rate of smoking), the French had a low incidence of cardiovascular problems (3). The duo coined this seemingly contradictory observation the “French Paradox” in which they hypothesized one primary cardio-protective factor responsible was the moderate consumption of red wine in the French diet.
A Healthy Aging Molecule
Despite the numerous biologically active components potentially contributing to the heart-healthy benefits of red wine the primary target of intense investigations has focused on resveratrol.
A decade after the French Paradox was proposed, resveratrol made yet another significant impact upon the scientific community. In 2003, a pioneering study found that resveratrol extended the life span of yeast by 70 percent through a mechanism involving activation of the protein SIRT1 (Sirtuin 1) (4). Subsequent studies found similar life-extending effects in other organisms such as worms, flies, and some fish. (See reference 5 for additional information.) Evidence of life span extension in higher mammalian species, however, such as rats have yielded more equivocal results although even in many of those studies, resveratrol offered metabolic and cardiovascular benefits.
Besides potentially activating SIRT1, resveratrol may also positively affect health via activation of another protein, AMPK (6). Through this modulation resveratrol may influence mitochondrial biogenesis (creation of newer, healthier mitochondria), stress responses, energy metabolism, and other critical functional cellular pathways.
Other potential mechanisms attributing to reseveratrol’s biological benefits include protection against platelet aggregation thereby reducing their susceptibility to “stick” and clump in arteries as well as its antioxidant properties (7,8).
Antioxidant and Heart-Healthy Benefits
While resveratrol’s mechanisms of action remain of significant interest to scientists there have also been numerous clinical studies investigating the polyphenol. For example, some studies have reported heart-healthy and metabolic benefits of resveratrol supplementation (8,9) while others have reported improved cerebral blood flow (10). Additionally, Ghanin et al. (11,12) found six-week supplementation with 40 mg resveratrol offered significant antioxidant protection.
Combined with its excellent safety profile (13), the resveratrol contained in both CytoActives™ or IsaGenesis® allow for an easy, convenient route for obtaining significant doses of this potent plant-based substance.
Resveratrol & CytoActives
The metabolic and cardiovascular benefits of resveratrol are just one of several cellular-protecting substances present in CytoActives. Along with 50 mg resveratrol, one serving of CytoActives also contains 100 mg of highly bioavailable Coenzyme Q10, 4000 IU of vitamin D3, 40 mg of palm tocotrienols, and a proprietary blend of other healthy bioactives. Collectively, this healthy-aging formulation exhibits significant metabolic and cellular benefits to the major organs and systems of the body.
