Of course I also realize that human lifespans are much longer than mice, so perhaps we'd have to wait 30 years before any of us knew the resveratrol supplements were working. however if anyone reports endurance gains, that's a good sign!

I'd have to say I've had real endurance gains but nothing like that seen by untrained mice. Maybe those in better shape will see less dramatic results. I just did a 100 mile bike ride today with three friends and averaged just under 21 mph. (I'm 46) The last ten miles I was close to bonking and I'm feeling the pain now. I am no doubt stronger then I was in November when I upped my resv. to about 500mg. Now I'm up to about 1.2 g (99% resv) mixed with Miralax. I have no idea how much the miralax is helping absorption. I'm beyond any personnel doubt that the resv. is helping my stamina but I can't give a number by how much.

What type of Resv do you use?

[steelheader]

I've experienced a gain in endurance since starting taking resveratrol in November. (Now at a gram of 98%.) With a more upbeat and energetic approach to life my workouts go better. Is the resveratrol increasing my endurance directly or do I have increased endurance because my workouts have been going better? I don't know.

[efosse]

Thanks velo and steelheader!

Yes, there are obviously possible confounding factors with exercise, other supplements, diet, etc. but i like what you've said

But just to clairfy: are the apparent endurance gains ONLY from 500mg+ of powdered resveratrol mixed with miralax/everclear? Or have you experienced gains from taking resveratrol pills?

Much thanks,
efosse

P.S. I have not started taking resveratrol but I def will now...

I saw the endurance effects from pills I used in November. (Longevinex, NSI and Natures Way). In January I started using 99% synthetic resv. and added Miralax (no ethanol) about 3 weeks ago. I'm still using up all the pills I bought in November but at a lower rate to reduce the emodin effects. If you start taking resv for endurance please try to do a controlled power and/or stamina test before you start supplementing. I'm kicking myself for not hooking up my power meter on my bike prior to November. Tell us if you see any results. [thumb]

[efosse]

hey velo,

what's your intake of 99 percent resveratrol with miralax (i.e., how many milligrams)? (and why don't you use ethanol?)

and if you can give me an idea of an endurance test, PLEASE let me know. i just have access to a gym with the usual fitness equipment.

cheers,

[Ghostrider]

How do we rule out placebo effects?

[efosse]

You really can't... unless we have a double-blind random clinical trial!

BUT: a before/after test is better than nothing...

[quarter]

I have been using the country life brand at a minimum of 500mgs (5 caps) a day (and have experimented up to 1g (10 caps) a day) with quercetin. I am a club level 400meter runner. I have noticed zero endurence enhancement (or anthying else for that matter - including no laxative effect) - my training and race times have matched previous seasons.

When the country life runs out and provided personal funds are sufficient I am considering purchacing the higher purity powder in the hope that it may provide some noticable effects, placebo or otherwise.

If you have the money and a testing center near you, I'd recommend a VO2 test similar to this: http://www.washingto...5053000517.html I would also try to use the same test operator for the before and after tests.

I would also keep your current exercise program and not ramp up to a higher workout level. It is possible that I think I am getting stronger so I work harder therefore I get better workout so I am actually getting stronger the old fashioned way, by suffering. Until somebody does a double-blind random study with humans I'm just providing a single anecdotal data point that is not worth much.

I am not impressed with Country Life. No noticeable effect. Let me know if the synthetic stuff works better. I think Country Life became popular on this board a half-year ago because it offered the most quantity for the dollar.

[electric buddha]

Country life, 400mg, no noticeable effect on endurance. And I'm pretty heavy on workouts. Though, on the other hand, I'm becoming tempted to think that there is an effect on mood after stopping it for a while where before I would have said there was none at all.

In short though, too much potential for a placebo effect to really judge without hard numbers.

[maxwatt]

I use a bicycle ergonometer (computrainer) regularly through the winter. I began taking Orchid 99%+ resveratrol at 400 mg daily. I saw a 15% improvement in sustained power output, over what I obtained with a similar level of training the year before.

I am currently at 2 grams per day in two one-gram doses, either with food or using a Miralax suspension. When I began using Miralax (about 50% of the time) a saw an improvement in my ability to spin uphill at a high cadence. I don't have numbers to put on this, but I've never been able to sustain such a high cadence with any power before.

This is consistent with the papers showing increased number and quality of mitochondria in rat muscle with high doses of resveratrol, though it does not meet the gold standard of a double blind study.

Incidentally, I've seen references to unpublished industrial studies, showing resveratrol extracts from P. cuspidatum increase the number of chloroplasts in the leaves of plants when an alcohol extract is spayed on the leaves.

[malbecman]

I will contribute my anecdotal evidence too:

I'm taking ~1gram of 99% for the last month, starting first on NSI and Nature's Way capsules back in January. I definitely notice an improvement in long term endurance. I can now easily run 6-7 miles and not feel bonked anymore or tired later. Also, on a bike with my HR monitor, I can keep my HR and power output at much higher maximums for longer periods without feeling overtired later.

But, as Steelheader said so well " Is the resveratrol increasing my endurance directly or do I have increased endurance because my workouts have been going better? I don't know". Thats a good question!

I am thinking of waiting a couple of months and giving resv. another try w/ a different brand.

Suggest using a 98% or better powder, possibly solubulizing with lecithin or Miralax as described in another thread.

There seem to be a lot of people using high quality powder. I've been somewhat out of the loop for a while, where is this coming from? Did that bulk purchase from 2006 go through with someone becoming a reseller?

[tintinet]

It's everywhere!

1. See the terrific page comparing pricing Anthony Loera of RevGenetics has postsed: Here!

2. Yes, several large shipments of high purity t-resv. have been received by some individuals posting here relatively recently.

3. Ya. You are out of the loop!

[nozza]

Anecdotal evidence like this is pretty worthless though isn't it? I've read a number of bodybuilding forum threads with people proclaiming evidnece of their latest substance which a while later is proven to be worthless.

Also people who have been doing endurance exercise getting better at that endurance exercise is not limited to those taking a supplement.

[Anthony_Loera]

I agree, it's pretty difficult to see if rsv increases endurance without studying it with a control group.

having said that, I do believe it has increased my endurance. I am an office worker mostly, and go home, watch TV and play with my son. That's really my extent of exercise in the day, but I have noticed an increase in endurance while in Las Vegas this past weekend.

(Well it could have also stemmed from the fact I had some good times at the crap tables and could not really sleep Sunday night after the end of the Natural Products Association conference.)

Bump, any updates on endurance?

[edward]

I mentioned this when I first started taking resveratrol. I had a big increases in endurance , lowered heart rate, increased capacity (upped treadmill running by if I remember correctly by about 2 mph and I hadn't done this in a very long time) I also play tennis and my endurance there has also improved. Everything leveled off though and I don't notice it much anymore.

[VP.]

Everything leveled off though and I don't notice it much anymore.

I've notice the same. Rapid increase in endurance but than a leveling off that has not improved even though I've doubled my dose and used Miralax to boost the effect. A strange thing happened to me after I got back from Bali. I did not take any Resveratrol for 9 days while in Bali (Indonesia has the death penalty for drug trafficking so taking a zip lock bag of white power didn't seem prudent) Two days after getting back I caught a cold (a very rare occurrence for me). After I recovered from my cold I went on my usual group bike rides. I had my worst performances since I started talking higher doses of resveratrol. Poor power and endurance. I was easily dropped by the group. I thought it could be recovery from my cold or maybe the the after effects of some bad Bali water (even though I felt fine). Now I believe it might have been due to not taking resveratrol for 9 days. Is it possible? I'm back to my pre-Bali endurance so it's a possibility. Anyone else gone cold turkey off high doses of resveratrol (>1 gram a day)?

I'm beyond any personnel doubt that the resv. is helping my stamina but I can't give a number by how much.

Resveratrol is an aromatase inhibitor and this is probably why people experience gains in strength and stamina, as well as fat loss.

[valjean]

I'm an office worker and I do not practice any kind of exercies
except playing with my children.

I started taking resveratrol in December 06 and my swimmin performance
was around 600m at this time and I felt totally exahusted after that.

Last month I swam 4000m and my feeling was that I could have gone
much further but it simply starts boring me and I was very very
hungry so I decided to stop.

My level of resveratrol intake has increased since 2006 from 80 mg
to 800mg and 1500-1800 (sometimes 2000mg) a day for the last
3 month.

Furthermore I've noticed that the growth of my thumbnails has regenerated.
About 20 years ago I've injured both thumbs by squeezing them in a window
frame. And it was around 2 moth ago that the nail of my left thumb starts
to grow flat and glossy again (before it looks like a riffled potato chip). And
currently with my right thumbnail the same thing happens, the lower half
inch appears now smooth whereas the upper part shows a clearly riffled
profile.

If this is related to resveratrol I don't know, but it seems to coincide with
increasing my dose beyond 1500 mg.
