Glycemic Identity Marks
A Symbol Of Quality, Commitment, and Integrity.
The Glycemic Identity Mark (GIM) is a symbol of quality and integrity for consumable products, valued by manufactures, retailers, and consumers. The GIM symbol on a product's label validates its claim, indicating independent evaluation by the industry's trusted Scientific Advisory Board with over 30 years of expertise in Glycemic Index and Science Of Sweetness. This ensures that products conform to the strict quality certification standards of the Glycemic Research Institute.

INDEPENDENT
INVESTIGATIONAL REVIEW
BOARD, INC (IIRB)
​
The primary function of the Independent Investigational Review Board, Inc. [IIRB] is to protect the rights and welfare of human subjects involved in clinical investigations.
IIRB activities are conducted in accordance with the Food and Drug Administration regulations (FDA), and the Department of
Health & Human Services.
IIRB RESPONSIBILITIES include:
​
â–ª Swift action for Phase I research
â–ª Comprehensive centralized review of Phase II, III and IV clinical investigations
â–ª Review of Device Studies
â–ª DHHS/OPRR compliance for FEDERALLY-FUNDED studies
â–ª Review of hospital-based studies
â–ª Cooperative research review
â–ª Blood/tissue (minimal risk) research review (in-service and education as needed)
IIRB fulfills its responsibilities through deliberate
consideration of all aspects of the research, including the assessment of the research setting, and the evaluation of the vulnerability of the research study participant.
The IIRB is an institutional review committee structured in compliance with both the regulations of the FDA contained in the Code of Federal Regulations (21 CFR 50 and 56) and in accordance with regulations described in 45 CFR 46 (DHHS).
The IIRB provides Assurance of Compliance with human subjects regulations as required by the DHHS when the research involves human subjects and is conducted by DHHS or supported in whole or in part by DHHS. In addition, the IIRB is in compliance with the regulations outlined in the
ICH/GCP guidelines.
IIRB was last inspected by the FDA December 2002 and was found to be in compliance with all regulations: 2022

LEGAL GLYCEMIC
CLAIMS PER FOOD & DRUG ADMINISTRATION (FDA)
THE FOLLOWING REGULATORY COMPLIANCE GUIDELINES APPLY:
U.S. FDA REGULATORY GUIDELINES REGARDING GLYCEMIC CLAIMS
FOOD & DRUG ADMINISTRATION FDA REGULATORY COMPLIANCE
“Glycemic Statement or Claims regarding the Glycemic Status of a product is only allowed on supplements, nutrients, or products if theGlycemic Index is based on a Clinical Trial of that specific product” FDA Regulatory Compliance
Further, the content and formula of the sweeteners and/or carbohydrates referenced is not required to be revealed by the inventor/formulator or its manufacturer, and can remain proprietary, as the FDA has determined that “Nutrient Content is not defined for said carbohydrates, although the: Glycemic Clinical Trials are still mandatory for any claim or statement on said label. Labels must also still contain mandatory content.
