Protein Problems

Has anyone here ever experienced a feeling of dizziness/tiredness about 20 minutes after taking ON 100% whey?

So far in my internet research it could be a reaction to the a) lactose b) sucralose or c) glutamic acid...

Anyone have any experience with this?

When does this happen? during exercise? after? or just any time you drink the shake?

I would be very surprised if the whey was causing this, it sounds like you just need some carbs, if this is after exercise then that is certainly the case.

Being the experimental type i've tried it in a variety of situations. Before exercise, after exercise, during the day, in the morning, late at night. From what I've read ON 100% is meant to be low in lactose (and besides I can eat a bowl of icecream without feeling dizzy). Therefore I can probably rule out the lactose causing the issue.

This would lead me to think the issues aren't blood sugar related or blood pressure related and are actually being triggered by whatever's in the shake.

I'm trying to narrow the ingredient down so that I can establish what products I can use before I waste money on them. Promatrix, for example, doesn't seem to cause the same dizziness.

Yes, I experience this after taking progain. I presume it's because you're so full after it? I'd be absolutely stuffed after a progain shake and my head would be spinning, the same used to happen to me when I was taking whey, but to a lesser degree I think.

how long have you been taking whey?

when i first started i felt dizzy after drinking my shake but that went away after a week and havnt felt it since.

I suppose on and off for about 2 years. I've always treated it as a recovery tool to make it easier to get up for work after a tough night's training.

I had no problems with choc or sberry ProMatrix or RAM that I'd bought off Jon. I've never tried the ProX or Big Whey.

Ashamedly in the past, ive had the worst of the worst H&B junk whey while living in Scotland and even that didn't seem to have any detrimental effect (apart from being rank obviously). Now having had the misfortune to also try the H&B Protoplex MRP I had a similar dizzy reaction to my fun with ON 100%.

I could guess that the added glutamine in both could have contributed to and MSG reaction but even then I've never noticed headaches after eating too much poor quality signapore noodles or pringles. So really I'm not sure what it is. Maybe sucralose again?

I would be reluctant to ignore what is a very pronounced dizziness/lethargy etc. and I'd love to get to the bottom of it so that I can inform my future purchasing...

Anyone know where I can buy some trial packs of a variety of brands?

EDIT: I should say I've read many similar tales from bodybuilding.com forums etc. but never any enlightenment. Always dizziness 20 minutes after shake (like myself).

Update:

My girlfriend proposed a test. Buy some Splenda (sucralose). Take some Splenda. See what happens. Rightly enough the same thing happened - dizziness, lack of focus, brain fog etc.

So now I have to avoid any supplement with sucralose in it. Which is most of them. Funnily enough ProMatrix has sucralose in it so I wonder is it just in lower quantities than ON 100%.
