Creatine as a food supplement for the general population

Creatine Monohydrate as an Effective Supplement for Muscular Fatigue in an Ehlers-Danlos Patient

Patients with Ehlers-Danlos syndrome (EDS) frequently report symptoms such as chronic pain and muscular fatigue that can heavily impact their quality of life. The treatment for many of the physical symptoms of EDS is focused on supportive care, which may include physical therapy and exercise programs. However, many patients will experience difficulty in deriving benefits from these activities due to significant pain and fatigue from physical activity. We report a case of a 39-year-old female with a history of EDS whose physical capabilities were severely impacted by their chronic pain and fatigue symptoms. After little progress was made with their current treatment plan of analgesics, manual therapy, exercise, and physical therapy, the patient was supplemented with creatine monohydrate due to its studied benefits in muscular strength and endurance for athletes. Following supplementation, the patient reported significant benefits in their muscular fatigue symptoms, allowing them to engage in daily activities and exercises more effectively. This case demonstrates a potential addition to the treatment of EDS that can improve a patient's quality of life.

Mini-encyclopedia of mitochondria-relevant nutraceuticals protecting health in primary and secondary care-clinically relevant 3PM innovation

Despite their subordination in humans, to a great extent, mitochondria maintain their independent status but tightly cooperate with the "host" on protecting the joint life quality and minimizing health risks. Under oxidative stress conditions, healthy mitochondria promptly increase mitophagy level to remove damaged "fellows" rejuvenating the mitochondrial population and sending fragments of mtDNA as SOS signals to all systems in the human body. As long as metabolic pathways are under systemic control and well-concerted together, adaptive mechanisms become triggered increasing systemic protection, activating antioxidant defense and repair machinery. Contextually, all attributes of mitochondrial patho-/physiology are instrumental for predictive medical approach and cost-effective treatments tailored to individualized patient profiles in primary (to protect vulnerable individuals again the health-to-disease transition) and secondary (to protect affected individuals again disease progression) care. Nutraceuticals are naturally occurring bioactive compounds demonstrating health-promoting, illness-preventing, and other health-related benefits. Keeping in mind health-promoting properties of nutraceuticals along with their great therapeutic potential and safety profile, there is a permanently growing demand on the application of mitochondria-relevant nutraceuticals. Application of nutraceuticals is beneficial only if meeting needs at individual level. Therefore, health risk assessment and creation of individualized patient profiles are of pivotal importance followed by adapted nutraceutical sets meeting individual needs. Based on the scientific evidence available for mitochondria-relevant nutraceuticals, this article presents examples of frequent medical conditions, which require protective measures targeted on mitochondria as a holistic approach following advanced concepts of predictive, preventive, and personalized medicine (PPPM/3PM) in primary and secondary care.

Dietary creatine is associated with lower serum neurofilament light chain levels

Low creatine availability may be linked to an elevated risk of neuronal damage, yet this association remains inadequately explored at the population level. Utilizing 2013-2014 National Health and Nutrition Examination Survey data, the current study found a negative correlation between dietary creatine intake and serum levels of neurofilament light chain (NfL; a biomarker for neuronal damage) in a cohort of 1912 individuals (52.2% females) aged 20-75 years. This inverse association persisted even after adjusting for other nutritional variables known to influence neuronal viability. The observed pattern, where increased dietary creatine intake was associated with reduced circulating NfL levels, suggests potential protective effects of creatine against neuronal injury.

Crushing Muscles: A Case Study on Rhabdomyolysis, Renal Failure, and Compartment Syndrome Triggered by Pre-Workout Supplement Abuse

The use of steroids and protein-based dietary supplements for muscle enhancement is prevalent in contemporary society. While these products promise increased muscle mass and strength, they carry significant risks, including severe medical complications. The consumption of these supplements has been linked to adverse symptoms, including dehydration, gastrointestinal distress, dizziness, and alterations in heart rate and blood pressure, primarily due to ingredients like creatine, arginine, and caffeine. Following the proper dosage, ensuring adequate hydration, and consulting a healthcare provider to verify if the supplement's components could affect any pre-existing conditions is recommended. Indiscriminate use of these products, including taurine, can lead to serious side effects. We present a 36-year-old patient with severe rhabdomyolysis, life-threatening acid-base imbalance, renal and liver injury, and peripheral neuropathy associated with the use of performance-enhanced unregulated supplements and exercise. This case highlights the importance of recognizing and managing complications related to exercise-aid supplements, emphasizing early identification and management. Increasing social awareness and research on those products is highly needed to avoid supplement-associated complications and potential long-term disabilities.

Dietary Paper Mulberry Silage Supplementation Improves the Growth Performance, Carcass Characteristics, and Meat Quality of Yangzhou Goose

There have been few investigations into the health benefits and meat quality of supplementing Yangzhou geese with paper mulberry silage. One hundred and twenty 28-day-old Yangzhou geese were selected for the experiment and randomly divided into two groups: a control group (CON) and a paper mulberry silage group (PM), with six replicates in each group. The experiment lasted for a total of 6 weeks. The experiment found that compared with CON, PM had a promoting effect on the average daily weight gain of Yangzhou geese (p = 0.056). Sensory and nutritional analysis of breast muscles revealed a decrease in a* value (p < 0.05) and an increase in protein content (p < 0.05) following PM treatment. Through untargeted metabolomics analysis of breast muscle samples, it was found that 11 different metabolites, including guanidinoacetic acid and other substances, had a positive effect on amino acid metabolism and lipid antioxidant pathways of PM treatment. Overall, the strategy of feeding Yangzhou geese with paper mulberry silage is feasible, which can improve the sensory quality and nutritional value of goose meat. The experiment provides basic data for the application form of goose breeding, so exploring the impact of substances within paper mulberry on goose meat should be focused on in the future.

Hepatotoxicity due to dietary supplements: state-of-the-art, gaps and perspectives

Food supplements are products intended to complement the normal diet and consist of concentrated sources of nutrients or other substances with a nutritional or physiological effect. Although they are generally considered safe if the manufacturer's recommendations are followed, many of them have shown hepatotoxic properties. This can cause many diseases (e.g. steatohepatitis and cirrhosis) characterized by progressive damage and malfunction of the liver that in the long term can lead to death. A review of the literature was carried out to elucidate which dietary supplements have been associated with cases of hepatotoxicity in recent years, with emphasis on those relevant to the consumer and the new trends (e.g. cannabidiol). It has been reported that the supplements described as hepatotoxic are mainly of botanical origin (e.g. green tea or turmeric) and those used in sports (mainly anabolic androgenic steroids). There is a great variability of compounds described as causing liver damage, although sometimes it is not possible to identify them, because they are contaminants or adulterants of the products. In addition, the prevalence of toxic effects after the administration of supplements is difficult to define due to underreporting and the lack of specific studies. Globally regarding hepatotoxicity of dietary supplements, there is a paucity of well-conducted clinical trials on the efficacy of these compounds and the frequency of related liver damage, as the use of these products is largely uncontrolled.

Analysis of metabolites of bactrain camel milk in Alxa of China before and after fermentation with fermenting agent TR1 based on untargeted LC-MS/MS based metabolomics

Camel milk produces many beneficial functional compounds and affects body health through metabolism. The differential metabolites of bactrain camel milk in Alxa before and after fermentation were identified by liquid chromatography-tandem mass spectrometry based metabolomics (LC-MS/MS). The differential metabolite pathway types were also identified in this paper. We obtained the following results that 148 and 82 differential metabolites were detected in positive and negative ion mode respectively, 85 differential metabolites were shown a significant upward trend and 63 with downward trend after fermentation in positive ion mode. Meanwhile, 32 differential metabolites characterized upward trend and 50 characterized downward trend in negative ion mode. The differential metabolites were mainly organic acids, amino acids, esters, vitamins and other substances contained in camel milk. Among them, most up-regulated substances had the functions of lowering blood pressure, lowering blood sugar, treatment of inflammation, antibiosis and other effects. Many harmful substances were significantly down-regulated after camel milk fermentation. However, there were also some metabolites whose prebiotic functions have been weakened by camel milk fermentation, which may provide reference values for healthcare function, exploitation and application of camel milk.

Adaptogens on Depression-Related Outcomes: A Systematic Integrative Review and Rationale of Synergism with Physical Activity

Depression is considered the most important disorder affecting mental health. The aim of this systematic integrative review was: (i) to describe the effects of supplementation with adaptogens on variables related to depression in adults; and (ii) to discuss the potential combination with physical exercise to aid planning and commissioning future clinical research. An integrative review was developed complementing the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement (PROSPERO registration: CRD42021249682). A total of 41 articles met the inclusion criteria. With a Price index of 46.4%, we found that: (i) Hypericum perforatum (St. John's Wort) is the most studied and supported adaptogen (17/41 [41.46%], three systematic reviews with meta-analysis) followed by Crocus sativus L. or saffron (6/41 [14.63%], three systematic reviews with meta-analysis and two systematic reviews); (ii) it is possible that the significantly better performance of adaptogens over placebo is due to the reduction of allostatic load via the action of secondary metabolites on BDNF regulation; and, (iii) the number of studies reporting physical activity levels is limited or null for those that combine an exercise program with the consumption of adaptogens. Aware of the need for a multidisciplinary approach for depression treatment, this systematic integrative review provides an up-to-date view for supporting the use of St. John's Wort and saffron as non-pharmacological strategies while also help commissioning future research on the efficacy of other adaptogens. It also contributes to the design of future clinical research studies that evaluate the consumption of herbal extracts plus physical exercise, mainly resistance training, as a potentially safe and powerful strategy to treat depression.

Analysis of the efficacy, safety, and cost of alternative forms of creatine available for purchase on Amazon.com: are label claims supported by science?

Creatine monohydrate (CM) is an established and effective dietary supplement, but it is not the only form of creatine. We analyzed forms of creatine for sale on Amazon.com" title = "http://Amazon.com">Amazon.com and evaluated if the advertised claims are supported by the available scientific evidence. We also analyzed the cost per gram of the forms of creatine. A total of 175 creatine supplements were included and we reported the total creatine content per serving, form(s) of creatine in products, product claims, and prevalence of products third party certified. The identified products contained 16 forms of creatine other than CM. The prevalence of products containing functional ingredients with CM or forms of creatine was 29.7%, and the prevalence of products containing blends of different forms of creatine was 21.7%. Only 8% of products were third party certified. The products using only CM (n = 91) had a mean price per gram of $0.12 ± 0.08, whereas products using only other forms of creatine (n = 32) had a mean price per gram of $0.26 ± 0.17. Approximately 88% of alternative creatine products in this study are classified as having limited to no evidence to support bioavailability, efficacy, and safety.

Could dietary creatine intake modulate overweight elderly's selective attention and inhibitory function?

Aims: There is evidence that both aging and increased adiposity may impact creatine levels in the brain, and brain creatine levels are important for cognition. The aim of this study was to assess correlation between dietary creatine intake and cognition in in elderly women with overweight. Methods: Twenty seven overweight women over 60 years of age who were part of a larger study participated in an Eriksen Flanker Task (EFT) to asssess cognitive performance. Additionally, diet was assessed over 5 days via daily diary nutritional recalls and the estimate of the daily amount of creatine was calculated. Results: In the EFT when incongruente stimulus were presented there was a significant diferences between those with low and high intake of creatine (-35.3 ± 5.84; p < 0.001). Similarly, reaction time to answer incongruent stimulus (r = -0.383; p = 0.004) and the percent of correct answers (r = 0.743; p < 0.001) showed weak to strong correlations with self-reported daily creatine intake. Conclusions: In conclusion, our results suggest that in elderly women with overweight that dietary intake of creatine may influence cognitive ability. Clinical Implications: Our findings support the idea that intake of dietary creatine may be an important factor for cognition in older adults.

Low Tissue Creatine: A Therapeutic Target in Clinical Nutrition

Low tissue creatine characterizes many conditions, including neurodegenerative, cardiopulmonary, and metabolic diseases, with a magnitude of creatine shortfall often corresponds well to a disorder’s severity. A non-invasive monitoring of tissue metabolism with magnetic resonance spectroscopy (MRS) might be a feasible tool to evaluate suboptimal levels of creatine for both predictive, diagnostic, and therapeutic purposes. This mini review paper summarizes disorders with deficient creatine levels and provides arguments for assessing and employing tissue creatine as a relevant target in clinical nutrition.
