Uff-Da,

Maybe it's just me but I always bristle at the thought of needing to take normal foods in pill form so that vitamin companies can get richer selling useless products. If we don't eat our coffee, eggs and chicken in pill form why take tea that way?

Perhaps on an extended voyage to one of the moons of Jupiter, green tea pills might be a good idea, but on Earth I think a cupful at a time is the better way to get it. After all why forgo the pleasure of a tasty beverage? :D

How much caffeine is in one of those Rexall's 315 mg. tea-caps? Do they mention theophylline?

Lenin,

There is no mention on the label of caffeine or theophylline content. I imagine that if the healthful polyphenols are concentrated in the caps, though, it is entirely possible that the caffeine and theophylline content may be also. I read somewhere that the antioxidants in these extracts could be as much as 27 times as high as just drinking a cup of tea. If that is correct, maybe the caffeine might also be 27 times as high, in which case it is no wonder my BP soared. I also read somewhere that some of these caps use decaffeinated tea, but have no idea what brands. I don't recall the source now and frankly, don't have enough interest to pursue it. I bought the green tea extract caps on a whim, thinking that would be one way to get the benefits of green tea during periods I go through a kick of drinking herbal teas instead of green tea. But since the first try didn't work, it isn't a big enough deal for me to look at other brands or spend time reading up any more on it. I'll just have to plan on getting my antioxidants elsewhere. I did think, though, that others might be interested in knowing how much this particular extract caused my BP to soar.
