Cyanidin-3-Glucoside: A Compound Showing Great Potential

For years, epidemiological data has consistently shown that people who eat fruits have lower rates of cardiovascular disease, cancer, and are less likely to suffer from obesity and diabetes. Even before epidemiology was a scientific discipline, mothers, shamans, and healers of ancient times have always spoken of the inherent therapeutic power of fruits. In the modern age of biology, scientists and physicians have slowly been unraveling the underlying biochemical answers behind these mysteries. One very powerful resulting discovery are cyanidins. Cyanidins are pigments found in many red berries including but not limited to grapes, bilberry, blackberry, blueberry, cranberry, lingonberry, and raspberry in addition to being found in black rice.
Over the last ten years, scientists have become increasingly excited about one particular cyanidin, called cyanidin-3-glucoside (C-3-G). C-3-G is predominantly found in blueberries, blackberries, blackcurrant, and black rice. Like other cyanidins, C-3-G at the biochemical level is a potent antioxidant and displays free radical scavenging activities. This is important, as most modern theories of aging and disease have shown that oxidation of molecular cellular structures and free radical accumulation are two very potent biochemical mechanisms underlying the cellular damage that causes us to become ill and grow old.*
In order to fight against these destructive cellular mechanisms, our bodies employ the power of antioxidants, both those occurring within its cellular structure in addition to those found in nutritional sources. C-3-G has shown great antioxidant activities. In fact, compared to other similar anthocyanins, it has shown the highest oxygen radical absorbing capacity (a laboratory test used to measure antioxidant power). Not surprisingly then, C-3-G has now been shown to potentially play a role in fighting and preventing diabetes and obesity, cardiovascular disease, cancer, and improving eye function.*
Clinical studies involving C-3-G have shown various improvements in ocular function. Specifically, people ingesting C-3-G have said that the compound reduces eye pain, fatigue, can lead to improvements in night vision, and even reduce occurrence of blood shot eyes.* Additionally, animal and cell culture studies have shown that C-3-G can reduce the size of atherosclerotic plaques (this buildup of plaque formation in your arteries is what leads to heart attacks), as well as reduce total cholesterol levels, prevent excessive weight gain on a high fat western style diet, and maintain proper serum levels of glucose, insulin, and leptin preventing diabetes.* Finally, C-3-G has shown great promise as potentially playing a role in cancer therapy as it has shown the ability to decrease cancer cell motility and adhesion.* Clearly, much more work needs to be done to fully elucidate the various biochemical mechanisms and potential clinical applications of C-3-G in human disease and health, but in the meantime, nutritional supplementation with C-3-G can be incorporated with any healthy lifestyle regimen.
