"This antioxidant has so many more benefits than my normal antioxidant! I really am impressed with this product. ... It's a good value and very effective. ..." ~product review by Hailey

  • ProC3G™ black rice extract delivers high-powered, total-body antioxidant benefits

  • One of the most bioactive and clinically studied anthocyanins

  • Promotes anti-aging by defending the body against free radicals

In the discussion of high-powered antioxidants, there have historically been two main contenders: vitamin C and resveratrol. Careful and extensive research has demonstrated that these two nutrients deliver antioxidant protection against free radicals, thus helping us live longer, healthier lives. Now comes C3G (Cyanidin-3-glucoside), the next generation in cutting-edge, anti-aging nutraceuticals.

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 35 mg of C3G.

Anthocyanins (particularly C3G) have been found to 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, published studies reveal benefits for specific parts of the body:

Vision & Eye Health—a 2011 study found that C3G defends the retina from the potentially harmful effects of light.

Cardiovascular Health—a 2009 study suggests that C3G may support healthy cholesterol levels already within the normal range; a 2011 study demonstrated that C3G supports healthy blood flow and vasodilation (widening of the blood vessels).

Glucose Metabolism—C3G was shown in preliminary models to support the maintenance of healthy blood sugar levels through vascular mechanisms and the promotion of superoxide dismutase (SOD) activity.

Weight Loss—in vitro research suggests that anthocyanins may influence gene expression for fat metabolism, signaling the body to burn rather than store fat.

ProC3G from Black Rice Extract 4.4 5 8 8
Likely good enough to aid vision health... Likely good enough to aid vision health, but for potential help with "nutrient repartitioning" (via Glut4-RBP4 system), this product is a little too expensive for the amount of C3G needed to do the job. I buy 99% of my supplements from Swanson Vitamins, but this is one in that remaining 1% that does not currently compete at the price level of it's competition for what I use C3G for. I would still recommend it for other uses. January 15, 2014
good new product A more effective anitoxident product December 9, 2013
yes I saw this stuff on Dr. Oz and decided to try it, seems to be working. November 13, 2013
great C3G potency C3G is one of the most powerful anthocyanin antioxidants, and the 35mg potency is the best there is on the market, and with the discounted price, it is unbeatable on both counts (potency and price). September 5, 2013
The Power of AntiOxidants One of the most effective and powerful in its class. June 30, 2013
so far so good I haven't lost weight and no signs of anti-aging yet...but it's too soon to tell. I wish there would be overnight alleviation of these problems, but what I like is it's formula for free radical suppression so it's possible! I'm going for another bottle! June 13, 2013
from positive research some supplements,like ginseng provide noticeable results. others like this one are hard to tell because you don't necessarily feel anything from it. so I rely on the research studies, and trust that its a beneficial thing worth taking. a bit pricey ,but maybe will get cheaper as time passes. June 9, 2013
Very effective antioxidant This antioxidant has so many more benefits than my normal antioxidant! I really am impressed with this product. I am glad that Swanson came up with this one. It's a good value and very effective. I will continue to take ProC3G instead of my previous one. May 28, 2013
