Caffeine pills don't dissolve in hot tea I'm drinking Rooibos Vanilla Tea and I like to dissolve an 80 mg caffeine pill in it. I hand press the pills myself from pure caffeine powder. However, the pill doesn't dissolve very well in the tea. Instead, it either breaks into smaller pieces which float around or it doesn't dissolve at all.

Is there a creative way to make them dissolve, such as using some sort of binding agent? I already tried to use capsules, but I don't like the idea very much, because you have to open them and pour out the powder.
If it really has to be pills, then I guess you need to mix in something that dissolves more easily than the caffeine powder. Powdered sugar seems like a good candidate. I found a couple references to people using it as a binding material for other pills, so presumably it'll work.

Depending on how you're making your tea, you could also add the pill while you're boiling the water, to give it more time to dissolve, and to make sure it gets the full heat.
