Resveratrol and Cyanidin 3-Glucoside
Certain compounds improve body composition on their own, but work even better with exercise. Here’s the science.
Exercise mimetics are a hot topic in the research world. Broadly speaking, they’re drugs or supplements that activate some of the chemical pathways activated by exercise.
Colloquially, these exercise mimetics are called “exercise pills” because the hope is that they could eventually replace people having to get all sweaty in the gym. Theoretically, you could just sit at home, take some of these exercise mimetics, and get leaner and stronger. More likely, though, is that these exercise pills would work in conjunction with exercise, giving you better results that training alone.
The good news is that there’s increasing evidence that there are at least two effective “exercise pills” already available.
AMPK Activators
Notable among exercise mimetics are a class of chemicals known as “AMPK activators.” AMPK is the master metabolic sensor that kicks in as a result of the stress of exercise and it increases insulin sensitivity and the mitochondrial production of energy. It’s also involved in skeletal muscle metabolism.
Interestingly, some of the most potent AMPK regulators come from the plant world in the form of polyphenols, which are plant chemicals that have amazing effects on the human body ranging from improved blood sugar to the prevention of Alzheimer’s.
Chief among these AMPK-modulating polyphenols are resveratrol and cyanidin 3-glucoside. One study appears to bolster the exercise-mimetic capabilities of these AMPK regulators and polyphenols in general.
The Study
Scientists divided young rats into four groups. One group ate high-calorie feed with added fat. Call it the “Doritos diet.” Accordingly, the rats developed insulin resistance. The second group also went on this Dorito-style diet, too, only they got to wash them down with grape juice, a rich source of polyphenols.
The third group of rats got similarly fattened up, but they had to run on a treadmill for an hour 5 days a week. The last group was also fattened up, and in addition to running on the treadmill, they got to drink the polyphenol-rich grape juice.
What Happened?
The combination of exercise and polyphenol-rich grape juice had a synergistic effect on the rats. They had better systemic and skeletal muscle insulin sensitivity than the other groups, including, most importantly, the other exercise group that didn’t get the polyphenol-rich grape juice.
Their fatty livers ditched their fatty deposits and replaced them with glycogen. Their exercise capacity went up. Body composition improved.
All this happened on a dose of 32-33 mg/kg/day of polyphenol-rich grape juice, which contains far less resveratrol or cyanidin 3-glucoside than a human would get in just one capsule of either supplement.
And another study done specifically with cyanidin 3-glucoside found that the exercise mimetic, in addition to improving endurance in swimming mice, also increased muscle weight and protein content, while significantly increasing the population of mitochondria (which led to greater energy production) in their cells.
“Exercise Pills” Available Today
No one’s suggesting you start drinking gallons of grape juice to get leaner, bigger, and increase endurance. But you should augment your health by drinking/eating as many polyphenols as you can from diverse sources. However, two specific polyphenols definitely act synergistically with exercise. They’re the aforementioned resveratrol and cyanidin 3-glycoside.
Cyanadin 3-glucoside’s reputation for burning fat and building muscle is well known. There’s a ream of research (rat and human) showing it burns fat, increases insulin sensitivity, and shuttles nutrients preferentially to muscle. It’s sold as Indigo-3G (Buy at Amazon).
Resveratrol, sold as Rez-V (on Amazon), is an estrogen blocker and life extender, but more recent studies show that it also improves insulin sensitivity and increases testosterone levels, in addition to making muscle fibers grow. Now we can add fat burning and increased endurance to its resume, as the study described above explains.
