Maltodextrin as energy source

[Jaco-fiets]

I see Dischem is selling a new brand called Pro-10. Its well priced and unflavoured. They have a product called Pure Carbohydrated that is only malto dextrin. How is this as a only carb source?

Their Vitago is also dirt cheap so im considering buying the pure carb product and the vitargo and mix them 50/50 in my bottle. What you guys think?

i saw the advert as well. seems they selling the components so anyone can make up their own concoctions in emulation of existing products, without the price penalty..

Been riding on the infamous malto/fructose mix for well over an year now, incl Epic, TB, Attakwas etc. It was the first mix I ever used during proper hard long riding so initially I had nothing to compare it too, but never had a problem. The fear mongering from the 32GI crowd got me try it for a while. I found it to be useless, and I was seriously doubting my cycling abilities as a result. Switched back to Malto, BANG, no problems.

 

I found a bulk supplier on thehub but cannot remember who.. Bugger.. I think I got 9kg of mix (malto + fructose) for less then R150..

 

Oh, Knersis can supply if you are in the Cape, I'm now in JHB, hence the new supplier..

must say, i had a weird experience using 32GI today, ie, it didnt feel like it worked. Then again, the instructions do say to imbibe one serving 30min before the race/activity for best results. sounds like the liquid portion of the last minute carbo-loading regime...

 

Maybe i should try the infamous mix..

[Jaco-fiets]

Think i'll try it as well. I just dont like the formula. 1 cup maltodextrine; 6 tsp fructose; 1 tsp table salt; mix with 1 L water. I like to have specifics. Is one cup = 250grams and 1tsp = 5 grams. If memory serves correctly the study refers to a 2:1 glucose to fructose ratio. 250grams to 30grams is not exactly a 2:1 ratio.

 

Also, can one swop the maltodextrin for Vitargo?

Don't get stuck with the specifics. Just remember your working with volume and not weight. The one cup is a cooking measurement. I got a cheap set of measuring cups & spoons from clicks and works 100%.

Not so sure. I've been using the AJ muti mix (Professor Asker Jeukendrup mix) and even also converted another sports nut that swears by it. Also check out Asker Jeukendrup on the web (I follow his tweets) as he gives a lot of hands on experience.

 

Just keep in mind the many pricey products use AJ muti as its base and then bloat it with marketing hype.

[Jaco-fiets]

Cool i understand the volume thing but what about the ratio issue? If you go onto the Powerbar site they rave about the proven 2:1 concept and its directly derived from Asker's research

I mix it with an old washing detergent scoop (250ml i think..) in a 2:1 volume mix, i.e. Full cup malto, half cup fructose in 750ml bottle. I did a 5h ride on sat on just one bottle. I guess if you want to go all out you'll need a good kitchen scale and go for say 50-60g total mix per hour and set your drinking schedule accordingly..

some advice ;-), instead of the fructose with the MD, try 32Gi mixed with it, as fructose does not peak at all it tapers off, with the isomaltulose carb we use in 32Gi combined with MD you will get a nice peak and it will taper u off for longer than fructose :-) we have a non-flavoured/neutral flavour if u r worried about taste blends. This will also give you a 2 way digestive method.

 

By the way, just so you understand, 32Gi on its own digests two ways :-), thats whats unique about the carb, it releases immediately, but it also does a second pass through the liver, allowing 1000% take up and digestibility, nothing goes to waste. So adding in some MD if you really want to take it up to the 75gram mark is ok, u just need to play with it.

 

One more thing, Maltodextrin on its own is a shocker, it spikes like nothing on this planet, so be wary because when it wears off if you dont feed frequently and miss a feed, u will drop like a bomb from where u will really battle to recover :-)

Ride Mag (April/May 2011) has an interesting article on glycaemic index. Worth a read in above context.

** Edited the original post as refered by you as the 1/2 symbols where corrupted.

 

Thank goodness I keep an online copy of the muti mix:

 

½ cup maltodextrin

6 ½ tsp fructose

¼-½ tsp table salt

Combine in one liter of water, shake, and serve!

 

 

BTW, 1 cup is 48 tsp (teaspoons) so the above ratio is (maltodextrin:fructose:salt) 48:13:1

 

That makes it now easier for us to understand.

 

So here we are using 3,69 to 1 ratio and not 2:1

 

EDIT: The water ratio to the 48:13:1 is 202 ~ (water:maltodextrin:fructose:salt) 202:48:13:1

That is exactly in the lines i am thinking bud! I weigh off everything so that will be my plan with this

I still use 32GI for races. I just wanne play around with formula's in training rides. I see they actually shoot down 32GI in the new ride mag without calling it by name. What is your thoughts on that MDW?

Think i'll even add 5grams of D-Ribose to the mix. Still dont see why you cant substitute the malto with vitargo..............
