Acetaminophen (APAP) overdose is one of the most common causes of acute liver injury. The current standard-of-care treatment for APAP hepatotoxicity, N -acetyl- l -cysteine, is highly effective when administered early after overdose, but loses efficacy in later-presenting patients. As a result, there is interest in the identification of new treatments for APAP overdose patients. Natural products are a promising source of new treatments because many are purported to have hepatoprotective effects. In fact, a great deal of research has been done to identify natural products that can protect against APAP-induced liver injury...

The consumption of dietary supplements (DS) has resulted in a significant and escalating number of cases involving liver injury. It is crucial for clinicians and consumers to be well informed about the adverse effects of such products, leading to their discontinuation and timely reporting of any harmful cases. This article delves into the clinical perspective of DS-related hepatotoxicity, highlighting key concepts such as a systematic diagnostic approach. The discussion extends to notable examples of both currently popular and potential future dietary supplements, such as garcinia cambogia, turmeric, and ashwagandha, accompanied by an overview of recent findings...

INTRODUCTION: Clinicians have limited options outside controlled substances to address sleep disturbance, which left untreated can negatively affect patient outcomes in cardiovascular health, mental health, immunologic function, and more. For some, genetic factors may influence sleep disturbances. L-methylfolate, the active form of folate, plays a critical role in regulation of monoamine neurotransmitters known to have significant impact on sleep regulation: dopamine, serotonin, norepinephrine...

The Dietary Supplement Health and Education Act, a legislative measure ushering in a novel class of complementary healthcare products known as dietary supplements, will mark its 30th anniversary in October 2024. Over this 30-year period, dietary supplement usage evolved from a few hundred products made up mostly of vitamins, minerals, and select botanical extracts to more than 75,000 single- and multi-ingredient products that are now regular staples in the American healthcare system and used by half of all U...

Background: Glycine is a conditional non-essential amino acid in human and other mammals. It is abundant in the liver and is known for a wide spectrum of characteristics including the antioxidant, antiinflammatory, immunomodulatory, and cryoprotective effects. The amino acid is a naturally occurring osmolyte compatible with protein surface interactions and has been reported in literature as a potent therapeutic immuno-nutrient for liver diseases such as alcoholic liver disease. Oral glycine administration protects ethanol-induced liver injury, improves serum and tissue lipid profile, and alleviates hepatic injury in various conditions...

The United States Pharmacopeia (USP) is an independent, nonprofit science-based organization whose mission is to improve global health through public standards and related products for medicines, food and dietary supplements. Probiotic-based dietary supplements are increasingly popular in the marketplace and USP has developed fourteen monographs specific to probiotic ingredients, including representatives from the Genera Lactobacillus, Bacillus, Streptococcus, and Bifidobacterium . These monographs include the definition of the article, tests for identification, quantification assays (enumeration in the case of probiotics), limits for contaminants, and other quality parameters when appropriate...

INTRODUCTION: Health inequities and disparities in nutrition research exist among transmasculine people. A dearth of evidence on dietary supplement use and motivations exist, partially due to constrained collection of sex and gender identity in national surveys. OBJECTIVE: We sought to investigate common motivations and use of dietary supplements in a voluntary survey of transmasculine people. METHODS: A total of 48 participants completed an online survey detailing dietary supplement use, motivations, and demographic information...

Gamma-aminobutyric acid (GABA) serves as a pivotal neurotransmitter implicated in the pathogenesis of stress, anxiety, sleep-related disorders, and heart rate (HR) reactions. Heart-rate variability (HRV), modulated by the sympathetic and parasympathetic branches of the autonomic nervous system (ANS), offers insights into cardiac autonomic control and cardiovascular well-being. The present study aimed to explore the impact of GABA supplementation on emotional metrics, sleep quality, and HRV in sedentary women with overweight or obesity partaking in physical exercise...

Hemp hull is the outer coat of the hemp seed, derived from the plant Cannabis sativa L., Cannabaceae. While much attention has been paid to hemp seed for its oil, protein and micronutrient content, far less attention has been given to hemp hull, a side stream of hemp processing. Hemp hull is a source of bioactive compounds, dietary fiber, minerals as well as protein, lipids and carbohydrates. Of note, two bioactive compounds, n-trans-caffeoyltyramine and n-trans-feruloyltyramine have been identified in hemp hull as key bioactive compounds that support gut health, liver function and other physiological processes...

Concepts and definitions of 'healthy' have been evolving within clinical treatment algorithms as well as reference standards such as Body Mass Index and Dietary Reference Intakes. Consumers' perception of the word 'healthy' is also changing to reflect longer life span, need to stay active and in a good state of mental well-being while managing multiple diseases. Guidelines from the US Food and Drug Administration indicate that substantiating evidence for support of Structure/Function (S/F) claims for dietary supplements is best derived from clinical research conducted in a 'healthy' population...

The DSHEA is 30 years old and its place in providing legitimate protections for public health through relevant agency oversight has created a patchwork of legal and scientific requirements. In contrast, the European Union has rules on supplements and permitted ingredients. Given the context of a global supply chain for food ingredients any conflict between the legality of ingredients between the U.S/EU can inhibit the economic viability of international trade. The purpose of this review is to contrast these different systems of legislative oversight...

Spirulina ( Arthrospira platensis) is a cyanobacterium associated with multiple health benefits. Cardiometabolic diseases such as cardiovascular disease, nonalcoholic fatty liver disease, and diabetes are prevalent yet usually preventable non-communicable diseases. Modifiable risk factors for cardiometabolic diseases include excessive body weight, body inflammation, atherogenic lipid profile, and imbalanced glucose metabolism. This review explores the effects of spirulina on cardiometabolic diseases risk factors...

The use of nutritional supplements can lead to doping risk and no data exist on high school athletes' use of certified third-party tested supplements. A cross-sectional cohort design was developed using an anonymous survey. Descriptive data for supplement use, use of third-party tested supplements, and knowledge in high school athletes were reported. A total of 225 high school athletes, ranging from 14-19 years of age, from a private high school in the western US, were included in the analysis of the results...

Premenstrual syndrome is a common disorder in women of reproductive age characterized by a variety of cyclical symptoms with a great impact on their lifestyle. Available pharmacological options include both antidepressants and oral contraceptives, both of which have side effects, are expensive and not always effective. Vitamins, minerals and plant extracts have been proven to alleviate the symptomatology of the premenstrual syndrome. For this reason, the purpose of this study was to test the effectiveness of a commercial phytotherapeutic dietary supplement (PREMEN-CALM® : γ-aminobutyric acid, Rhodiola rosea L ...

Irritable bowel syndrome (IBS) is a functional gastrointestinal condition. Probiotics and other nutraceutical compounds can have specific indications in the context of IBS. A retrospective analysis was conducted on 123 IBS patients in order to evaluate the effects of an oral probiotic-based dietary supplement (Colicron, one cps/day for 4 wk) on stool consistency and pain intensity. Different time points were defined as follows: baseline (T0), 2 wk of treatment (T2), and 4 wk of treatment (T4). Stool consistency was assessed by using the Bristol Stool Scale...

Osteoarthritis (OA) is an age-related degenerative joint disease with a great impact on patients' well-being and quality of life. This is an observational, open, single-arm multicenter study aimed to evaluate the effectiveness of a nutritional supplement in patients with knee and/or hip OA. A total of 186 patients were recruited from Spanish centers and received a supplement containing hydrolyzed collagen (3000 mg), chondroitin sulfate (800 mg), glucosamine sulfate (700 mg), turmeric extract (250 mg) and devil's claw (150 mg), once daily during 6 months...

Boswellia serrata ole-gum-resin extracts (BSEs) are commonly used as food supplements, especially in osteoarthritis management. The quality standard is established by determining 11-keto-β-boswellic acid (KBA) and acetyl-11-keto-boswellic acid (AKBA) content using high-performance liquid chromatography (HPLC) or assessing the total boswellic acid (TBA) content by titrimetry. The limited geographical distribution of Boswellia species and increasing industrial demand could increase the risk of adulteration in Boswellia -containing products...
