NIH Extends Dietary Supplements Contract with AOAC;
Call for Methods: Turmeric, Black Cohosh, Vitamins B6 and B12

The National Institutes of Health (NIH), with the U.S. Food and Drug Administration acting as the officiating body, has renewed its contract with AOAC to determine the best methods for turmeric, black cohosh, and vitamins B6 and B12. Under a previous NIH contract, AOAC had assembled a network of experts to identify the best methods for development and validation of some 15 dietary supplement ingredients. AOAC will now engage this same network of experts to study these additional ingredients of interest.

As part of the new contract, AOAC is issuing an urgent call for validated methods for:

  • turmeric (for curcuminoids)
  • black cohosh (for phenolic acids and glycosides)
  • vitamin B6
  • vitamin B12

Turmeric, black cohosh, and vitamins B6 and B12 had been prioritized for study by the AOAC Presidential Task Force on Dietary Supplements’ Ingredients Ranking Subgroup because of the lack of validated methods for both their raw materials and finished products for dietary supplements. Dietary supplement ingredients are ranked in order of priority for methods validation, and source of funding is a major driving factor in decisions. Earlier studies have included method development on beta-carotene, chondroitin, CoQ10, ginkgo, ginseng, SAMe, saw palmetto, lycopene, and others.

AOAC welcomes methods from the dietary supplements industry, government, and academia. Please send the reference, the paper itself, or electronic copy of the method, as well as any available validation data, and please indicate whether reference standards are available and their source.

Interested parties are invited to submit methods by November 1, 2008. For more information, or to submit your methods, contact Bob Rathbone, Senior Director of Publications & Method Validation, at rrathbone@aoac.org".
