Russel J. Reiter, an international authority on melatonin, answers
the 10 most common questions about this antioxidant/hormone.

Also, I thought this group might be interested in some facts about
caffeine's effect on melatonin.  A group of 25 volunteers who were
given caffeine tablets equivalent to two cups of coffee had
a significant reduction in blood levels of melatonin for the next
eight hours. (a peak level of 14 pg/ml of melatonin when taking
caffeine; 25 when not.)
        [Sleep Research 1995; 24:458  "Effects of caffeine, bright
lights, and their combination on nighttime melatonin..." Wright,K.P
et al.]
        If you drink coffee and are under bright lights, you will
get an even greater reduction in melatonin levels.  Taking 
supplemental melatonin will offset this effect.
