June 1, 2004 Toronto, ON – Researchers at the University of Toronto, reporting in the Canadian Journal of Dietetic Practice and Research (Spring 2004, Vol 65 No.1), note that participants that took greens+ showed statistically significant increases in energy and vitality, as compared to those that took the placebo product. While a trend toward greater improvement in the greens+ group was noted in perception of wellbeing, overall mental health and decreased incidence of colds and flus, it did not reach statistical significance.
The prospective, randomized, double-blind, placebo-controlled clinical trial, analyzed 105 healthy women aged 25-55 who had never taken a green food product. The study period was 12 weeks with participants checking in every 4 weeks.
The women studied were asked to drink one serving of green food supplement or placebo mixed in 8oz of apple juice each morning. Neither the participants nor researchers knew which product (greens+ or placebo) participants received throughout the study. A taste test was done to confirm that placebo and green food supplement were indistinguishable in taste and texture.
"Patients increasingly are asking health care practitioners about the validity of these claims. In most cases, no research studies have been conducted on these products, which makes providing objective, accurate guidance difficult. This is one of the first studies to provide preliminary evidence that may enable both health care providers and consumers to make informed choices about natural health products."
