Why does my whey protein make me feel so awful?
I have been taking a simple whey protein suplement after weight training recently, but I am having a strong reaction to it. Every time I eat/drink it I start to feel amped like I've had too much caffeine and I get an annoying headache.
Just to be clear, the only ingredients appear to be milk whey and soy products. There is no listing of caffeine or creatine or anything similar. Also, I only eat/drink about 100 calories worth at one time and I drink cow's milk every day without any problems.
If it matters, the full name of the product is "Dymatize Nutrition ISO 100 Hydrolyzed 100% Whey Protein Isolate".

Have you increased your water intake since you've started using protein supps? Protein can build up in your liver and can possibly reach toxic levels - this probably isn't causing your headaches, but it's good to know anyway.
A lot of protein powders have contain Aspartate, which can cause migraines and headaches. Aspartate is a sweetener that's many many times stronger than sugar, (100 times or more) it excites the neurons in your brain to the point that it can actually kill cells.
