                April 26–27, 2016
                The safety of botanical dietary supplements is an important public health issue. This workshop engaged experts from multiple disciplines to focus on practical approaches for addressing challenges in botannicals such as developing methods and criteria for assessing phytoequivalence of botanicals, identifying active constituent(s) or patterns of biological response of botanicals, and assessing absorption, distribution, metabolism, and elimination of botanicals. Participants discussed the relative merits of dedicating scientific attention to identifying the active constituent(s) in botanicals and identifying biological signatures that are predictive of adverse events (biomarkers of effect). Presentations addressed promising approaches (e.g., high throughput screening, computational tools) and accompanying challenges for using these approaches to advance the understanding of the risks associated with botanical use. This workshop was co-sponsored by the National Institutes of Health (NIH) Office of Dietary Supplements and the National Institute of Environmental Health Sciences National Toxicology Program.


                • Options for Consideration of Chronic Disease Endpoints for Dietary Reference Intakes (DRIs)

                  This intensive workshop brought together experts to provide a forum to consider options for including chronic disease endpoints in the setting of future dietary reference intakes (DRIs).  The DRIs are widely used in the design and evaluation of research studies and results, in planning and monitoring nutrition-related public health programs and initiatives, in assessing the nutritional status of individuals and groups, and in patient and consumer counseling and educational programs.  The information will be used in planning for future DRI reviews.  Panel experts included nutrition scientists, biostatisticians, epidemiologists, clinical trialists, and toxicologists.



                  • Vitamin D Standardization Program (VDSP) Symposium: Tools to Improve Laboratory Measurement
                    November 14, 2013
                    The Office of Dietary Supplements (ODS), National Institutes of Health, established the Vitamin D Standardization Program (VDSP) in November 2010 to standardize the laboratory measurement of vitamin D status worldwide. Standardization is essential to improve the detection, evaluation, and treatment of vitamin D deficiency and insufficiency by making measurements of serum total 25-hydroxyvitamin D [25(OH)D] accurate and comparable over time, location, and laboratory procedure. ODS leads this collaborative effort with the National Institute of Standards and Technology (NIST); the Centers for Disease Control and Prevention (CDC); the Laboratory for Analytical Chemistry of Ghent University, Belgium; and the Vitamin D External Quality Assessment Scheme (DEQAS), U.K.; and the College of American Pathologists (CAP). Key VDSP participants also include the national health surveys from Australia, Canada, Germany, Ireland, Mexico, South Korea, the United Kingdom, and the United States; numerous consultants from around the world also participated.  VDSP is part of the ODS Vitamin D Initiative.
                    • The Use and Biology of Energy Drinks: Current Knowledge and Critical Gaps
                      August 15–16, 2013
                      "Energy" drinks are marketed as promoting alertness, concentration, energy, weight loss, athletic performance or stamina. Products within the scope of this workshop contain caffeine and other ingredients such as amino acids, vitamins, herbal supplements and sugar or other sweeteners. These drinks are the fastest growing component of the U.S. beverage market; half the consumers of these products are under 25. The published data on the biological effects of many of the ingredients in these products, and on their effects when combined, are limited.
                      • Nutrition and Diet in Heart Failure Managementexternal link disclaimer
                        June 5–6, 2013
                        The National Heart, Lung, and Blood Institute (NHLBI) and NIH Office of Dietary Supplements (ODS) convened a working group on June 6 and 7, 2013. Members were asked to: 1) assess the evidence base for dietary and nutritional guidance for heart failure (HF) patients; 2) identify critical evidence gaps regarding the efficacy and clinical utility of dietary interventions for meeting nutritional needs, mitigating symptoms, and potentially arresting or reversing HF progression; and 3) consider how to develop new knowledge in the field and approaches for translation that will optimally use existing or new evidence, including novel study designs and methodological approaches. An important aspect of this working group was the dialogue among experts representing cardiology, nephrology, nutrition science, biostatistics and clinical trials, and basic science. In addition to NHLBI and ODS, representatives from NIDDK, NIA, and NINR participated. These stakeholders considered needs, opportunities, and obstacles regarding medical nutrition therapy (MNT) and HF management.

                                                                      Dietary supplement use is so pervasive in the United States today that it is becoming impossible to obtain estimates of total nutrient intakes without accounting for them. This session at the 2005 American Dietetic Association's Food & Nutrition Conference & Expo presented current data about why people use dietary supplements, how to collect and assess information about them, and some authoritative resources that dietitians can use.
                                                                      • Workshop on Diet, Nutrition, and Dietary Supplement Use in Autism: Evaluation of the Evidence
                                                                        October 6, 2005
                                                                        The workshop provided NIH with an overview of the current state of the science on dietary supplements and related interventions in managing autism; identified specific scientific questions concerning research needs and opportunities; and provided examples of the role of dietary supplements under investigation in management of autism spectrum disoder.
                                                                        • Role of Betaine in the Treatment of Alcoholic Liver Disease
                                                                          October 3, 2005

                                                                          • Omega-3 Fatty Acids and their Role in Cardiac Arrhythmogenesis Workshop
                                                                            August 29–30, 2005
                                                                            The major goals for this workshop were to: (1) review the epidemiological evidence and the data from randomized trials on the role of omega-3 fatty acids in susceptibility to arrhythmias and sudden cardiac death; (2) explore the basic mechanisms by which omega-3 fatty acids affect cardiac excitability at the cellular and organ level; (3) identify the gaps and barriers in basic understanding of the effects of omega-3 fatty acids on cardiac electrical activity at the cellular, tissue, and whole body levels; and (4) provide prioritized recommendations for additional research studies to (a) better understand the basic mechanisms coupling omega-3 fatty acids to cardiac electrical activity and (b) facilitate translation of this knowledge to the treatment and prevention of cardiac arrhythmias.
                                                                            • Use and Misuse of Biomarkers as Indicators of Cancer Risk Reduction Following Dietary Manipulation
                                                                              July 12–13, 2005

The conference goals were to review and discuss the criteria for surrogate endpoints for cancer risk, identify biomarkers that are influenced by diet and determine their relationship to cancer risk and tumor behavior, and explore emerging biomarkers for their relevance to nutrition and cancer prevention.
