(1) I have no 'dog in the fight'. Meaning I buy this stuff at retail. Who
out there has a dog in the fight that has commented? Do you currently sell,
distribute, or are sponsored by a nutritional product?
(2) Attached are the original sites for the clinical data with Vitargo.
http://www.vitargo.com/ You'll see that they were published in substantial
journals. Are they substantial enough for you? Maybe not, but again what
nutritional product are you currently using and what data do they have.
Right...nothing. Only Vitargo and Cytomax have any published clinical data.
Also, what product do you currently use, do you actually know what's in it?
Some don't and actually have false blood tests for banned substances!
Nutritional supplements are not monitored by the FDA and any of these
companies can claim ANYTHING without backing it up. I find it interesting
that the above companies actually have published data and others
don't....why....because they don't have to and again can make any claims
they want. Buyer beware....
(3) Let's dumb this thing down a little...
This particular carb molecule is simply larger than any carb type currently
being used in sports drinks. The molecular weight (MW) is 500,000-700,000 vs
maltodextrine 1000-10,000 and dextrose 180. Therefore, it is 70% quicker at
replenishing glycogen and 80% quicker passing through the stomach. The
published data they have supports this information. Simple. +++MW therefore
absorbed differently....that's it.
(4) My point....
I simply was introducing you to what I have found to be a very cool carb
source that has helped me with my training and racing. If your happy with
what ya got etc. That's cool. There are a lot of great products out there
that might work well for you. This might be another one to consider...being
that most of you probably have not heard of it because the various brands
aren't sold everywere.
That's it for me on this subject....
Best Regards,
