Caffeine depends mostly on the dose, and of course if you drink it with certain medications (like those against asthma or emphysema). The compound itself is the same in all sources. The effect of caffeine on blood pressure is usually short-lived, and so is not an automatic no-no for people with problems. Coffee and tea both yield antioxidants, which also have benefits, though if they are not organic can sometimes yield toxins; they also have tanins, which can drain vitamins and minerals out of the body. The recommended daily upper limit is 500 mg for adults, 100 mg for children (less than 18 years of age). The average content per 8 fl oz of coffee is 100 mg (though it can get up to 200 mg), and tea is in the 20s, though it can get up to 60 mg.
Best bet: organic tea or coffee, no more than 3 cups per day; note that rooibos tea (from South Africa, also known as “red” tea) has no caffeine, but is still antioxidant-rich.

Well, it depends on how are you taking it? I think that coffee is “worse” than tea (some of which also contain its variant of caffeine)… but I’m hardly an expert. Caffeine can help if you have an occasional low blood pressure, and likewise, you should avoid caffeine if you have high blood pressure or accelerated pulse.

Is it really that bad for us?
