Red wine has 1.5 to 3 mg of resveratrol per liter

The compound resveratrol, believed to benefit longevity and heart health for its antioxidant properties, seemed to undermine the cardiovascular benefits of exercise in a small study.
When some plants (like grape vines) are under stress, they produce a polyphenol known as resveratrol, which you may have heard of as the "anti-aging" chemical. Resveratrol has been shown to improve cardiovascular performance and extend the lives of non-mammals and mice -- specifically improving the lipid profiles and longevity of mice who ate a lot of fat. We believe that's because of its work as an antioxidant.
The mice in that study got a boatload of resveratrol, though. Red wine has 1.5 to 3 mg of resveratrol per liter, so an average person would need to drink 1,000 liters of red wine daily to get that much. Resveratrol does come in supplement form, but is that good for humans? Some believe that a certain amount of oxidative stress is necessary, so we shouldn't drown ourselves in antioxidants.
METHODOLOGY: Twenty-seven healthy but physically inactive men (all 65 and older) undertook intense eight-week regimens of CrossFit and circuit training. Some took 250 mg of resveratrol as well, and some took a placebo. The researchers monitored multiple metrics of cardiovascular fitness throughout the course of the exercise program.
RESULTS: By the end of the exercise program, the placebo group had a 45 percent greater increase in maximal oxygen uptake than the resveratrol group. The placebo group also saw a decrease in blood pressure, but the resveratrol group did not. Levels of a vasodilator prostacyclin (a good thing) were also lower in the resveratrol group, and the resveratrol group did not experience the positive effects on cholesterol and triglycerides that the placebo group did.

Maybe it just means that if you’re taking resveratrol that you don’t need to exercise to live longer?
Just don’t take too much.
Salute!
Damn, I take that stuff.
That will undo the effects of exercise too.
Oh good!! This sounds like a challenge.
I can’t afford. Will cheap Tequila work as well? It’s made from plants, cactus IIRC.
What are we to make of this?
This study is complete BS! The benefits of exercise are not static and exercise, although very beneficial does create free radicals and increased oxidation. How the human responds to the stresses of exercise is dependent on many factors and are individual not general. In fact, as far as blood pressure goes, normal blood pressure ranges are not the only parameters to monitor, it is the difference between your systolic and diastolic pressures that are very important, as well. As for lipid levels, the powers that be have been wrong about cholesterol for decades. If you could afford it, it would do your body good to consume 250 to 500 mg. Of trans-resveratrol daily. Soon it will be in the form of anti-aging prescription medicine, slightly altered in the lab.
In Great Health.
Don’t put too much faith into 1 study
The government has funded thousands of fake global warming studies. all of them FAKE, bogus, pure lies .the Earth is not even warming but the studies say that our cars are destroying the planet by emitting C02 which warms the Earth and so will destroy the EArth. Lol pure communist bs
a lot of studies and “science” are bs.
