Procter & Gamble
Conducts Clinical Trials with Glycemic Research

Procter & Gamble, the world's largest consumer products company, announced that their clinical trials on Metamucil have been completed at the Glycemic Research Institute, and have successfully passed the protocol for “Low Glycemic.”

The Human In Vivo Clinical Trials were conducted under the direction of Dr. Ann de Wees Allen, Chief of Biomedical Research, Glycemic Research Institute. During the clinical trials, human subjects were fed P & G’s Metamucil Berry Burst product to determine its glycemic properties, including blood glucose and insulin responses. Additionally, the product was shown not to stimulate adipose tissue fat-storing.

Metamucil Berry Burst passed all legal protocols for Low Glycemic claims, and did not elevate blood glucose or insulin levels.

P & G is displaying the United States government authorized Seal of Approval Certification owned by the Glycemic Research Institute (GRI) on its Metamucil Berry Burst product in marketing and advertising.

The Glycemic Research Institute Certification is the only glycemic Seal authorized in the United States. GRI’s glycemic Certification is also authorized by government authority in the UK and Canada. The Glycemic Research Institute has been the industry leader in glycemic research for the past 23 years.
