Creasy and Resveratrol

Discussion in 'Food and nutrition' started by Stuart Cracraft, Jan 29, 2004.

  1. Something I hadn't heard before in 3rd from last paragraph, as regards persistence of the molecule
    and the effect of light.

    Things are looking up.

    "Creasy's tests show that resveratrol is preserved even in open wine, with only a 3 percent
    reduction after 17 days sitting open on a counter at about 70 degrees or refrigerated at about 35
    degrees. He believes that resveratrol lasts longer in wine than in pill form because of the anti-
    oxidant properties in wine. However, wine will lose its resveratrol if it is exposed to light, so
    keep an opened bottle away from a window."

    Oh, but what about storing open bottles of red wine under Ar or N2 and consuming them within 2-3
    days? Lol. It's good to see some real numbers.

    I'd still like to know how certain supplement manufacturers are preparing their Licaps and what
    analytical proof support their claims regarding oxidation, or lack thereof, in their products.

    From a recent thread:
    >Actually I think you are looking at the molecule on the previous page. Compare these instead:

    This article is apparently from the NY times. Sure, *that* structure is correct.

    >http://www.longevinex.com/sdm.asp?pg=molecule

    Yes! Longevinex has the wrong molecule; moreover, they have "RESVERATROL: The Molecule"
    stamped on it.

    It seems as though I've entered half way through a discussion. Sorry, I'm new to the group.

    As for the testing, etc., why not have the company release some GC/MS or HPLC or some other
    analytical data? All it can do is support this apparently wonderful product. Your anecdote
    regarding chronic obstructive pulmonary disease is nice as far as these reports go. Furthermore,
    the reference is good but tells me nothing about the quality of Longevinex Resveratrol over the
    competitors. My university doesn't carry the current 12 months of Thorax so if you have a copy of
    the .pdf, please post it.

    I'm not doubting that it works, I'm doubting that the product you're endorsing is better than the
    competitors.

    Yes, the stuff is much more stable than some people suggest. :)

    In dry powder form it ought to be even more stable.

    > He believes that resveratrol lasts longer in wine than in pill form

    Belief is the domain of religion. Where are the facts (measurements) ?

    You know what? If you have a requirement for specific data, get out your PC and write an email to
    the manufacturer and request lab results.
