Higher tea intake showed similar results, while decaffeinated coffee did not โ€” suggesting that caffeine may be the active factor producing these neuroprotective results, though further research is needed to validate the responsible factors and mechanisms.

I have caffeine sensitivity and only drink decaf so uhhhh fuck me I guess ๐Ÿ˜”

I feel that!

Decaf is pretty comparable to some kinds of tea in terms of caffeine content. I know when I make decaf it has way more caffeine than when I make black tea.

Decaf coffee has less than 1mg/ floz

Black tea is generally over 5mg/floz

Are you basing this on how alert you feel or do you have some very weak tea and some super strong decaf?

I make decaf stronger because I like the taste but I also leave teabags in. I wonder how much variance there is between different decafs in reality. This is based on my own experience in my own body but I do suspect that not all decafs are made equal.
