after using Resveratrol for two weeks (one pill a day) I started having daily nose bleeds

Thanks for sharing. What was your daily dose? Did you start with a lower dose ?

If you want you can report your side effects to http://www.resveratrol-side-effects.info/report-side-effects

I'll make sure to notify them too. 

I just want to say that I've had a similar experience. After about 2 weeks taking 200mg/day single-dose Resveratrol I developed very severe nosebleeds.  This has happened to me twice, with about one year between the events.  (I doubted that the Resveratrol was the cause the first time, so I tried taking it again.  I now have no doubts.)

In my case the nosebleeds have been very severe, and I lost about 8 ounces of blood or more with each bleed. Very frightening... Probably some peculiar interaction with my metabolism, but should certainly appear someplace as a possible side-effect.
