Potential Benefits of C3G 20% Extract Tablets

The existing animal and cell-based studies are summarized below; they should guide future research efforts but should not be interpreted as supporting any health benefit.

Ameliorates Hyperglycemia

In laboratory experiments, cyanidin 3-glucoside (C3G) has shown the ability to reduce fat tissue and cells in mice fed a high-fat diet and exhibiting elevated blood fat levels. C3G was found to enhance fat cell differentiation, which is typically impaired in diabetes. This suggests a potential role for C3G in managing obesity-related aspects of diabetes and reducing hepatic steatosis. [R]

Research involving diabetic mice revealed that C3G led to a decrease in fasting blood glucose levels. Additionally, it appeared to mitigate diabetic complications by protecting the kidneys, liver, and pancreas from damage. [R]

A statistical analysis of various rodent studies indicated that C3G supplementation could enhance insulin sensitivity, increase insulin secretion, and reduce post-meal blood glucose levels in treated groups. These findings highlight C3G’s potential to improve blood sugar regulation. [R]

Vascular Failure Prevention

Preclinical research has suggested that C3G can lower cholesterol levels, potentially contributing to improved heart health. Berry extracts containing C3G were found to reduce cholesterol levels in rats subjected to a high-cholesterol diet while increasing high-density lipoprotein (HDL) cholesterol, considered beneficial. [R]

Studies involving diabetic rats indicated that those treated with cyanidin 3-glucoside experienced less heart damage that could lead to heart disease compared to the control group. This suggests a potential cardioprotective role for C3G in participants with diabetes. [R]

C3G was also observed to have an inhibitory effect in the process of platelet aggregation when applied to human blood platelets from both healthy men and women. This anti-platelet effect may contribute to the prevention of atherosclerotic plaque formation. [R]

Metabolic Syndrome

Research conducted on rats demonstrated that C3G could reverse symptoms associated with metabolic syndrome, including excess belly fat, elevated glucose levels, and high blood pressure. This suggests that C3G may be beneficial for participants at risk of health issues related to metabolic syndrome. [R][R]

Liver Protection

Dietary supplementation with cyanidin 3-glucoside was shown to reverse signs of liver damage in mice with liver injuries over an eight-week period. This protective effect was attributed to the reduction of inflammation and cell death in the liver, indicating the potential for C3G in liver health. [R]

H. Pylori Infection

In a study involving human stomach cells affected by Helicobacter pylori (H. pylori) infection, cyanidin 3-glucoside demonstrated the ability to reduce cell death by blocking the release of toxins. This suggests a potential role for C3G in protecting against the harmful effects of H. pylori infection in the digestive system. [R]

Weight Management

C3G-rich extracts from black rice have demonstrated effects on body weight and food intake in animal studies, raising the possibility of its utility in obesity management. While many of these effects were observed in animal models, the consumption of anthocyanin-rich foods containing C3G has been associated with potential health benefits in humans. [R]

Potential Anticancer Properties

Emerging research has hinted at the potential anticancer properties of C3G, although further investigations are necessary to substantiate these claims. Preliminary studies have suggested that C3G may inhibit the growth of certain cancer cells and reduce the risk of cancer development, but this research is still in its early stages. [R]

Heart Disease Prevention

A certain study found that supplementing with cyanidin-3-O-β-glucoside (Cy-3-G) offers a potential protection against endothelial dysfunction caused by high cholesterol levels in apolipoprotein E-deficient mice. Additionally, it may help reduce the development of atherosclerosis. One noteworthy discovery was that a metabolite called PCA, which originates from Cy-3-G, effectively inhibits the infiltration of monocytes in these ApoE-deficient mice. [R]

This finding suggests that the antiatherogenic (atherosclerosis-preventing) effect of foods or extracts rich in Cy-3-G may be due, in part, to PCA. Therefore, future research should focus on exploring the biological properties of polyphenol metabolites, not just the polyphenols themselves. [R]

To summarize, this study demonstrated that Cy-3-G is efficiently converted into PCA within the ApoE-deficient mice. It also showed that both Cy-3-G and PCA treatments may reduce monocyte/macrophage infiltration, both in laboratory settings and in living organisms, by negatively influencing the expression of CCR2. [R]

This suggests that Cy-3-G and its metabolite PCA may hold potential clinical significance in reducing the severity of atherosclerosis, a condition characterized by the buildup of plaque in arteries. [R]

How It Works

The mechanism of action of cyanidin 3-glucoside (C3G) is an active area of human studies, offering promising insights into its positive effects. Preliminary experiments suggest that C3G exerts its inhibitory effects through powerful antioxidant activity, mitigating oxidative stress in the body and thereby potentially protecting the heart and blood vessels.

Furthermore, C3G-containing anthocyanin extracts have been shown to increase the activity of proteins involved in fat tissue regulation, with UCP-2 being of particular interest as a potential genetic marker and treatment target for type II diabetes.

C3G may also play a role in immune system modulation, potentially reducing Th2-dominant immune responses associated with hyperactive allergic reactions. It’s important to note that C3G’s activation in the body requires specific enzymes to convert it from its precursor, cyanidin 3-rutinoside, and its digestion and absorption remain areas of investigation.

Studies suggest that less than 1% of C3G may be utilized, and it may undergo further conversion into active compounds yet to be identified. Interestingly, the presence of human gut bacteria may enhance C3G digestion, underscoring the role of the intestinal environment in its utilization.

Ongoing research, including clinical trials and studies on bioavailability, will provide a deeper understanding of C3G’s mechanisms of action and potential health benefits.
