Seasonal Affective Disorder

Nobody has to put up with mild cases of Seasonal Affective Disorder in MY practice! A double-blind, placebo-controlled study that enrolled 20 U.S. Marines suggests that tyrosine can improve mental alertness during periods of sleep deprivation. In this study, the participants were deprived of sleep for a night and then tested frequently for their alertness throughout the day as they worked. Compared to placebo, 10 to 15 grams of tyrosine given twice daily seemed to provide a “pick-up” for about 2 hours.
