"Scientific journals and three independent American scientists have raised
questions about the validity of Dr. Chandra's findings, saying the study,
published in September 2001 in the journal Nutrition, has statistical
irregularities and inconsistencies, and is characterized by improbable
research methods.
The study purported to demonstrate striking cognitive benefits for people
over 65 who took a daily multivitamin-mineral supplement that Dr. Chandra
formulated and has since patented. He licensed the rights to the supplement
to the Javaan Corporation, founded by his daughter, Amrita Chandra Gagnon.
The company, in Somerville, Mass., sells the supplement as Javaan 50."
