Anxiety and Caffeine

[peacemaker]

I made an interesting observation. Its probably not the caffeine alone which makes the anxiety and heart rate up. It has to be done by the other substances in coffee, tea and so on. Because (it does not true every time) if I take too much coffee, or even tea, I start feeling sometimes very bad. But a pure caffeine pill, or cola with an equal or twice of amount of caffeine does not produce those effects. What do you think about this theory?

That`s a good point you make especially with the cola.  When i drink a nice cold cola with caffeine i certainly don`t get worse anxiety but i have no idea about the ratio of caffeine in a can of cola compared to a pod coffee made from a machine.  Although lately i have been having diet fizzy drinks so it wouldn`t make a difference.

I would like to look into that ingredient (Theobromine) in the above post from Richard or maybe some other ingredient, actually i wonder if there is a similar ingredient other than caffeine in those energy drinks.  I really hate the feeling i get after drinking energy drinks..
