Be Proactive About Your Health—ProC3G™ from Black Rice Extract Provides Total-Body Antioxidant Benefits

As Seen on TV!

Swanson Ultra ProC3G from Black Rice Extract
Lee Swanson

Lee Swanson, President of Swanson Health Products®

First there was vitamin C, the antioxidant vitamin that changed the way we think about nutritional supplementation. Then came resveratrol, the "secret" free-radical fighter in red wine that excited our imaginations and altered our understanding of antioxidants altogether. Now C3G (Cyanidin-3-glucoside) emerges as the cutting-edge nutraceutical at the forefront of our scientific quest for natural solutions to help us live longer, healthier lives.

What is C3G?

C3G belongs to the same class of phytonutrients as other popular antioxidants found in fruits, vegetables, herbs and grains. Known as anthocyanins, these water-soluble nutrients are analogs of the plant pigments responsible for blue, red, orange and purple coloring. Many anthocyanins have been isolated, researched and found to be beneficial for human health. C3G is one of the most predominant anthocyanins found in nature. It's also one of the most bioactive nutrients in its class and one of the most clinically researched.

What does C3G do?

According to published research, anthocyanins (particularly C3G) nourish the body by supporting a variety of fundamental mechanisms. C3G may defend against free radicals generated by oxidative stress and has been shown to support healthy cellular aging through its powerful antioxidant activity. In addition, studies demonstrate distinct benefits for specific organs and systems:

C3G for Healthy Eyes: A 2011 study found that C3G defends the retina from the potentially harmful effects of light by supporting the healthy structure and function of photoreceptors. Scientists also theorize that C3G may promote healthy blood vessel function within the eyes.1

C3G for a Healthy Heart: A 2009 study conducted with 120 participants suggests that C3G may support healthy cholesterol levels already within the normal range through its influence on a key marker of cholesterol metabolism known as cholesteryl ester transfer protein (CETP). A 2011 study with 150 individuals demonstrated that C3G supports healthy blood flow and vasodilation (widening of the blood vessels) by promoting healthy activity of the nitric oxide/cyclic GMP pathway, a key mechanism in the maintenance of healthy blood vessels and healthy blood flow.2,3

C3G for Healthy Glucose Metabolism: In a preliminary study using animal models, C3G was shown to support the maintenance of healthy blood sugar levels through vascular mechanisms and the promotion of superoxide dismutase (SOD) activity.4 Further trials to confirm these benefits in human subjects are underway.

C3G for Weight Management: Another preliminary trial comparing the effects of C3G supplementation in animals fed high fat vs. normal diets found that supplementation resulted in significantly less weight gain in those consuming high fat diets.5 In vitro research suggests that anthocyanins may influence gene expression for fat metabolism, signaling the body to burn rather than store fat.6

What makes ProC3G the ultimate C3G supplement?

ProC3G is a highly concentrated, natural source C3G supplement derived from Oryza sativa black rice. With a 35% C3G content, it delivers 10 times more C3G than the best-selling anthocyanin extracts on the market today. Each capsule of Swanson Ultra® ProC3G delivers 100 mg of C3G. You would have to eat about five cups of black rice to get the same amount of C3G found in just one of our capsules! ProC3G is the pure, natural, easy way to put the power of the world's most exciting anthocyanin to work for your good health.
