A Plant-Based Dietary Supplement Improves Measures of Metabolic Detoxification and the Quality of Life: A Phase II Multicenter Randomized, Blinded, Placebo-Controlled Clinical Trial.

Background: Persistent accumulation and hindered clearance of toxins from tissues over time may promote the development and exacerbation of several diseases. Hepatic metabolic detoxification is a key physiological process responsible for the clearance of toxic substances from the body. A healthy diet with nutritional dietary supplementation may support metabolic detoxification and help mitigate the negative effects of toxin burden. Methods: A multicenter, randomized, single-blind, controlled trial was conducted to test the effects of a dietary detoxification product (detox; n = 20) versus an active dietary control product (active control; n = 20) on selected biomarkers of metabolic detoxification, general health, and well-being following 28 days of dietary supplementation. Study participants displayed multiple symptoms commonly associated with elevated toxin burden, but otherwise healthy. Results: The detox group displayed significantly decreased levels of red blood cell total toxic metals, decreased urine total porphyrins, and decreased urine mutagenicity potency compared with baseline. Both the detox and active control groups showed improvements in the symptoms attributed to elevated toxin burden. Fatigue and sleep disruption scores were significantly reduced in the detox group compared with baseline. No significant differences in anthropometric measures and vital signs, and no adverse events or side effects were detected in either group over the study period. Conclusions: This study demonstrates the benefit of nutritional intervention for supporting metabolic detoxification, evidenced by significant changes in multiple detoxification biomarkers and improvement in questionnaire scores related to quality of life, general health, and well-being.

The Opioid Crisis and the Future of Addiction and Pain Therapeutics.

Opioid misuse and addiction are a public health crisis resulting in debilitation, deaths, and significant social and economic impact. Curbing this crisis requires collaboration among academic, government, and industrial partners toward the development of effective nonaddictive pain medications, interventions for opioid overdose, and addiction treatments. A 2-day meeting, The Opioid Crisis and the Future of Addiction and Pain Therapeutics: Opportunities, Tools, and Technologies Symposium, was held at the National Institutes of Health (NIH) to address these concerns and to chart a collaborative path forward. The meeting was supported by the NIH Helping to End Addiction Long-TermSM (HEAL) Initiative, an aggressive, trans-agency effort to speed scientific solutions to stem the national opioid crisis. The event was unique in bringing together two research disciplines, addiction and pain, in order to create a forum for crosscommunication and collaboration. The output from the symposium will be considered by the HEAL Initiative; this article summarizes the scientific presentations and key takeaways. Improved understanding of the etiology of acute and chronic pain will enable the discovery of novel targets and regulatable pain circuits for safe and effective therapeutics, as well as relevant biomarkers to ensure adequate testing in clinical trials. Applications of improved technologies including reagents, assays, model systems, and validated probe compounds will likely increase the delivery of testable hypotheses and therapeutics to enable better health outcomes for patients. The symposium goals were achieved by increasing interdisciplinary collaboration to accelerate solutions for this pressing public health challenge and provide a framework for focused efforts within the research community. SIGNIFICANCE STATEMENT: This article summarizes key messages and discussions resulting from a 2-day symposium focused on challenges and opportunities in developing addiction- and pain-related medications. Speakers and attendees came from 40 states in the United States and 15 countries, bringing perspectives from academia, industry, government, and healthcare by researchers, clinicians, regulatory experts, and patient advocates.

Do specific dietary constituents and supplements affect mental energy? Review of the evidence.

The numbers of marketing claims and food, beverage, and drug products claiming to increase mental energy have risen rapidly, thus increasing the need for scientific specificity in marketing and food label claims. Mental energy is a three-dimensional construct consisting of mood (transient feelings about the presence of fatigue or energy), motivation (determination and enthusiasm), and cognition (sustained attention and vigilance). The present review focuses on four dietary constituents/supplements (Ginkgo biloba, ginseng, glucose, and omega-3 polyunsaturated fatty acids) to illustrate the current state of the literature on dietary constituents and mental energy. The strongest evidence suggests effects of Ginkgo biloba on certain aspects of mood and on attention in healthy subjects, as well as associations between omega-3 polyunsaturated fatty acids and reduced risk of age-related cognitive decline. Limitations of the current data and challenges for future research are discussed.
