I have not tried caffeine pills myself, but I have found caffeine in general to be slightly beneficial, but with coffee having the most pronounced effect on my symptoms.
Likely an effect of MAO inhibitors in coffee. Caffeine itself is also a MAO inhibitor (in addition to its primary effect of adenosine receptor antagonism), but there are dozens of others in the brew.
