Interactions with Dietary Supplements
L-tryptophan and
Niacin
Akathisia is an adverse reaction to anti-psychotic drugs, where a person has an uncontrollable
desire to be in constant motion. One preliminary report suggested that 4,000 mg of
L-tryptophan and 25 mg niacin per day taken with benztropine enhances the treatment of
akathisia.1 Controlled studies are necessary to determine whether L-tryptophan and
niacin supplements might benefit most people taking benztropine who experience adverse
reactions to anti-psychotic drugs.
