Abstract
BACKGROUND Garcinol is a naturally occurring compound from the fruit rind of the Garcinia indica, with antioxidant, anti-inflammatory, and anticancer properties. Curcuminoids are the active molecule from the rhizome of Curcuma longa, studied extensively for its health benefits as an anti-inflammatory and antioxidant activities. Non-alcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic steatohepatitis characterized by liver fat and inflammation. OBJECTIVE To evaluate the clinical efficacy and safety of Garcinol, Curcuminoids and piperine (GCP) combination in patients with mild to moderate NASH in a randomized, double-blind, placebo-controlled study. METHODS The patients received one tablet (450 mg) of GCP containing garcinol-50 mg, curcuminoids -250 mg and piperine 5 mg or a placebo (450 mg of microcrystalline cellulose) twice daily for 90 days. Changes in circulating aspartate aminotransferase (AST), alanine transaminase (ALT) levels, liver stiffness measurement (LSM), and controlled attenuation parameter (CAP) using Fibroscan were compared from baseline to day 90. Anthropometric parameters, serum levels of lipids, Interleukin (IL-6), hsCRP, and adiponectin were estimated. Safety was evaluated by laboratory parameters and by monitoring adverse events. RESULTS Seventy-two patients were randomized and 63 (GCP = 32, Placebo = 31) completed the study. The mean age of the patients was 48.3 ± 8.7 years (36 males and 27 females). The mean reduction in AST (U/L) was 9.53 in GCP and 3.16 in placebo (p < 0.001) and that of ALT (U/L) was 13.47 in GCP and 7.43 in Placebo (p = 0.002). The liver stiffness and CAP scores showed a better reduction in GCP (0.56 kPa and 12.38 db/m) compared to placebo (0.064 kPa and 10.42 db/m) p < 0.05. Consequently, the noninvasive Fibroscan-AST (FAST) score reduction was also found to be significant in GCP compared to placebo. Additionally, body weight, lipid levels, hsCRP, and IL-6 in serum decreased, while adiponectin levels increased in GCP-supplemented participants compared to placebo. The combination of garcinol and curcuminoids was well tolerated with no significant changes in hematological and clinical laboratory parameters during the 90-day supplementation. CONCLUSION Our results suggest that GCP could be a possible supplement for the management of NASH.Clinical trial registration: https://clinicaltrials.gov/, identifier CTRI/2019/11/022147.

Plain language summary
The reasons for bloating and feelings of stomach discomfort are not fully understood and it is thought that they may be caused by several factors. Amongst these is the possibility that small intestinal bacterial overgrowth (SIBO) and gut microbiota alterations play a role in the development of bloating. Many therapies exist for the symptomatic relief of bloating, however probiotics may be effective for the relief of bloating due to the role of gut microbiota in its development. This randomised control trial of 66 individuals with abdominal bloating, discomfort, and gas aimed to determine the effectiveness of a gut bacteria strain known as Bacillus coagulans MTCC 5856 on feelings of gas and bloating. The results showed that supplementation with B. coagulans MTCC 5856 for 4 weeks relieved feelings of bloating, burping, and gas. It was concluded that B. coagulans MTCC 5856 supplementation was effective at relieving gas and bloating and may be a safe approach for individuals who experience these symptoms. This study could be used by healthcare professionals to recommend B. coagulans MTCC 5856 as a safe and effective therapy for individuals who suffer from gastrointestinal problems such as gas, bloating and stomach discomfort.
Abstract
BACKGROUND Gut microbiome dysbiosis is a major cause of abdominal gas, bloating, and distension. Bacillus coagulans MTCC 5856 (LactoSpore) is a spore-forming, thermostable, lactic acid-producing probiotic that has numerous health benefits. We evaluated the effect of Lacto Spore on improving the clinical symptoms of functional gas and bloating in healthy adults. METHODS Multicenter, randomized, double-blind, placebo-controlled study at hospitals in southern India. Seventy adults with functional gas and bloating with a gastrointestinal symptom rating scale (GSRS) indigestion score ≥ 5 were randomized to receive B coagulans MTCC 5856 (2 billion spores/day, N = 35) or placebo (N = 35) for 4 weeks. Changes in the GSRS-Indigestion subscale score for gas and bloating and global evaluation of patient's scores from screening to the final visit were the primary outcomes. The secondary outcomes were Bristol stool analysis, brain fog questionnaire, changes in other GSRS subscales, and safety. RESULTS Two participants from each group withdrew from the study and 66 participants (n = 33 in each group) completed the study. The GSRS indigestion scores changed significantly (P < .001) in the probiotic group (8.91-3.06; P < .001) compared to the placebo (9.42-8.43; P = .11). The median global evaluation of patient's scores was significantly better (P < .001) in the probiotic group (3.0-9.0) than in the placebo group (3.0-4.0) at the end of the study. The cumulative GSRS score, excluding the indigestion subscale, decreased from 27.82 to 4.42% (P < .001) in the probiotic group and 29.12 to 19.33% (P < .001) in the placebo group. The Bristol stool type improved to normal in both the groups. No adverse events or significant changes were observed in clinical parameters throughout the trial period. CONCLUSIONS Bacillus coagulans MTCC 5856 may be a potential supplement to reduce gastrointestinal symptoms in adults with abdominal gas and distension.

Plain language summary
Several studies have reported the positive effect of probiotics on restoring the gut microbiome in conditions of gut dysbiosis. However, the impact of probiotics on gut microbiome composition in healthy individuals is not very well established. The aim of this study was to investigate the impact of B. coagulans MTCC 5856 supplementation on the changes in the composition and abundance of gut microbiota. This study was a randomised, double-blind, placebo-controlled trial. The subjects (N = 30) were randomised to receive either of the 2 investigational products: probiotic intervention vs palcebo. Results showed that the metagenome analysis revealed no major changes in the gut microbiome composition in individuals supplemented with B. coagulans MTCC 5856. However, minor positive changes were observed in supplemented individuals. Furthermore, the probiotic did not adversely affect abdominal health, stool pattern, or clinical and biochemical parameters. Authors concluded that B. coagulans MTCC 5856 is a safe probiotic, maintains gut health, and general health parameters in the normal range, and does not grossly alter the gut microbiota composition in healthy humans, thereby maintaining the delicate host-microbe relationship in the gut ecosystem.
Abstract
BACKGROUND Probiotics are known to rebalance the gut microbiota in dysbiotic individuals, but their impact on the gut microbiome of healthy individuals is seldom studied. The current study is designed to assess the impact and safety of Bacillus coagulans (Weizmannia coagulans) microbial type culture collection 5856 (LactoSpore®) supplementation on microbiota composition in healthy Indian adults. METHODS The study participants (N = 30) received either LactoSpore (2 billion colony-forming units/capsule) or placebo for 28 days. The general and digestive health were assessed through questionnaires and safety by monitoring adverse events. Taxonomic profiling of the fecal samples was carried out by 16S rRNA amplicon sequencing using the Illumina MiSeq platform. The bacterial persistence was enumerated by quantitative reverse transcription-polymerase chain reaction. RESULTS Gut health, general health, and blood biochemical parameters remained normal in all the participants. No adverse events were reported during the study. Metataxonomic analysis revealed minimal changes to the gut microbiome of otherwise healthy subjects and balance of Bacteroidetes and Firmicutes was maintained by LactoSpore. The relative abundance of beneficial bacteria like Prevotella, Faecalibacterium, Blautia, Megasphaera, and Ruminococcus showed an increase in probiotic-supplemented individuals. The quantitative polymerase chain reaction analysis revealed highly variable numbers of B. coagulans in feces before and after the study. CONCLUSION The present study results suggest that LactoSpore is safe for consumption and does not alter the gut microbiome of healthy individuals. Minor changes in a few bacterial species may have a beneficial outcome in healthy individuals. The results reiterate the safety of B. coagulans microbial type culture collection 5856 as a dietary supplement and provide a rationale to explore its effect on gut microbiome composition in individuals with dysbiosis.

Abstract
Metabolic syndrome (MetS) is characterized by the presence of at least three interrelated risk factors, including central obesity, hypertension, elevated serum triglycerides, low serum high-density lipoproteins, and insulin resistance. Abdominal obesity is considered a predominant risk factor. Lifestyle changes with medications to lower cholesterol, blood sugar, and hypertension are the general treatment approaches. Functional foods and bioactive food ingredients represent versatile tools for addressing different aspects of MetS. In a randomized placebo-controlled clinical study, we evaluated the effect of Calebin A, a minor bioactive phytochemical from Curcuma longa, on metabolic syndrome in obese adults (N = 100), and 94 individuals completed the study (N = 47 in both groups). They were subjected to Calebin A supplementation for 90 days, which resulted in a statistically significant reduction in their body weight, waist circumference, body mass index, low-density lipoprotein-cholesterol, and triglyceride levels compared to those with the placebo. A small but significant increase in high-density lipoprotein-cholesterol levels was also observed in these individuals. Furthermore, Calebin A showed a positive effect on adipokines by reducing circulating leptin levels. Finally, C-reactive protein levels were significantly reduced in Calebin A-supplemented individuals, suggesting a beneficial impact on managing MetS-induced inflammation. Blood glucose levels, insulin resistance, and blood pressure levels were not affected by Calebin A. In conclusion, Calebin A may be an effective supplement for managing abdominal obesity, dyslipidemia, and systemic inflammation in individuals with metabolic syndrome. This study was prospectively registered on the Clinical Trial Registry of India (CTRI) with the registration number CTRI/2021/09/036495. https://ctri.nic.in/Clinicaltrials/advancesearchmain.php.

Abstract
PURPOSE There has been a growing interest in the use of probiotics and their products for skin care, over the last decade. LactoSporin is the extracellular metabolite of a spore-forming probiotic Bacillus coagulans (Weizmannia coagulans) MTCC 5856, with antimicrobial and skin protecting activity. PATIENTS AND METHODS The anti-skin-aging potential of LactoSporin was evaluated in a randomized, double-blinded, placebo-controlled study in healthy female participants (70 screened and 56 randomized). The participants applied either LactoSporin or matched placebo formulation (N=28 in each group) for 10 weeks, and the effects were assessed by dermatological, and non-invasive instrument-based evaluation using Antera, Cutometer, Corneometer, and Tewameter. All the 56 participants completed the study and were included for the analysis. RESULTS The regular use of LactoSporin cream for 10 weeks showed a significant reduction in visibility of wrinkles around crow's feet, nasolabial folds, frown lines, and facial fine lines compared to baseline and placebo by dermatological and Antera assessments. LactoSporin showed improvement in skin elasticity and hydration by dermatological assessments, but the effect was not significantly different from placebo when assessed by Cutometer, Corneometer, and Tewameter. No adverse events or skin irritation was observed in any participants during the study. CONCLUSION These results suggest that LactoSporin could be a safe natural ingredient to reduce wrinkles and fine lines in cosmetic formulations.

Majeed, M, Nagabhushanam, K, Prakasan, P, Mundkur, L
International journal of molecular sciences. 2022;(9)
Abstract
The SARS-CoV-2 infection is a highly contagious viral infection, which has claimed millions of lives in the last two years. The infection can cause acute respiratory distress, myocarditis, and systemic inflammatory response in severe cases. The interaction of the viral spike protein with the angiotensin-converting enzyme in various tissues causes damage to vital organs and tissues, leading to complications in the post-infection period. Vaccines and antiviral drugs have improved patient response to the infection, but the long-term effect on vital organs is still unknown. Investigations are now focused on supportive nutrient therapies, which can mitigate the susceptibility as well as the long-term complications of COVID-19. Selenium is one such micronutrient that plays a vital role in preventing oxidative stress induced by the virus. Further, selenium is important for effective immune response, controlling systemic inflammation, and maintain overall health of humans. We examine the role of selenium in various aspects of SARS-CoV-2 infection and address the importance of selenium supplementation in reducing the susceptibility and severity of infection in this review.

Nutrients. 2021;(2)
Abstract
Obesity, an epidemiological disorder, is related to various complications in both the developed and developing world. It epitomizes a crucial risk factor for health, decreasing productivity and life expectancy while increasing health care costs worldwide. Conventional therapies with synthetic drugs or bariatric surgery, associated with numerous side effects, recurrence, and surgical complexity, have been restricted in their use. Lifestyle changes and dietary restrictions are the proven methods for successful weight loss, although maintaining a strict lifestyle is a challenge. Multiple natural products have been explored for weight management with varied efficacy. The current review explores less explored natural herbs, their active constituents, and their mechanisms of action against obesity.

Abstract
The acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has affected millions of individuals, causing major health and economic disruptions worldwide. The pandemic is still raging, with a second and third wave in a few countries, while new infections steadily rise in India. Nutrition and immune status are two critical aspects of fighting the virus successfully. Recently, selenium status was reported to positively correlate with the survival of patients with COVID-19 compared with non-survivors. We analyzed the blood serum levels in 30 apparently healthy individuals and in 30 patients with confirmed COVID-19 infection in the southern part of India. The patients showed significantly lower selenium levels of 69.2 ± 8.7 ng/mL than controls 79.1 ± 10.9 ng/mL. The difference was statistically significant (P = 0.0003). Interestingly, the control group showed a borderline level of selenium, suggesting that the level of this micronutrient is not optimum in the population studied. The results of this exploratory study pave the way for further research in a larger population and suggest that selenium supplementation may be helpful in reducing the effects of the virus.

Osteoarthritis (OA) is an age-related, degenerative joint disorder which affects many people worldwide. It causes pain, most frequently in the large joints such as knee and hips and is characterised by pain, decreased mobility and negative effects on the quality of life. This randomised, double-blind placebo controlled trial of 48 adults between the age of 35 and 75, aimed to evaluate the safety and efficacy of Boswellia serrata extract on newly diagnosed or untreated patients with OA of the knee. 340mg of Boswellia serrata extract was administered daily in 2 doses to the treatment group for 120 days. Outcome measures were WOMAC scores on pain, stiffness and physical function; a 6 min walk test assessing distance; physician assessment of range of motion, strength, stability and tenderness; x-ray images of joint space and growths; and hs-CRP, a blood marker of inflammation. The researchers found that the treatment group significantly improved, with reduced pain and stiffness compared to placebo. X-ray assessment also showed significantly improved knee join space and reductions in abnormal bone spur growth in the treatment group. Additionally, the treatment group had significantly lower hs-CRP compared to placebo. No adverse effects were reported. Whilst this is a small trial, Nutrition Practitioners working with patients with OA could consider the use of Boswellia serrata extract in their supplement protocols.
Abstract
A double-blind, placebo-controlled human trial was conducted to evaluate the safety and efficacy of a standardized oral supplementation of Boswellin®, a novel extract of Boswellia serrata extract (BSE) containing 3-acetyl-11-keto-β-boswellic acid (AKBBA) with β-boswellic acid (BBA). A total of 48 patients with osteoarthritis (OA) of the knee were randomized and allocated to the BSE and placebo groups for intervention. Patients were administered BSE or placebo for a period of 120 days. The trial results revealed that BSE treatment significantly improved the physical function of the patients by reducing pain and stiffness compared with placebo. Radiographic assessments showed improved knee joint gap and reduced osteophytes (spur) confirming the efficacy of BSE treatment. BSE also significantly reduced the serum levels of high-sensitive C-reactive protein, a potential inflammatory marker associated with OA of the knee. No serious adverse events were reported. This is the first study with BSE conducted for a period of 120 days, longer than any other previous clinical trial on patients with OA of the knee. The findings provide evidence that biologically active constituents of BSE, namely, AKBBA and BBA, act synergistically to exert anti-inflammatory/anti-arthritic activity showing improvement in physical and functional ability and reducing the pain and stiffness.

Abstract
Functional dyspepsia (FD) is a highly prevalent disorder having nonspecific symptoms and varied pathophysiology. Its treatment remains a challenge as therapeutic options are limited, unsatisfactory, and elusive. Thus, safety and efficacy of DigeZyme®, a proprietary multienzyme complex (MEC), was evaluated as a dietary supplement in FD patients. In this randomized, double-blind, placebo-controlled, parallel-group study, 40 patients were randomly assigned (1:1 ratio) to receive either MEC (50 mg, TID; n = 20) or placebo (n = 20) for 60 days. Reports of adverse or serious adverse events (AEs), abnormal results of vital signs, abnormal findings during physical examination, and abnormal laboratory investigations were monitored closely. Efficacy measures were change in Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ), Nepean Dyspepsia Index-Short Form (NDI-SF), Visual Analog Scale (VAS), Clinical Global Impression Severity Rating Scale (CGI-S), and Glasgow Dyspepsia Severity Score (GDSS) at baseline and follow-up visits on day 15, 30, and 60. Supplementation with MEC was associated with statistically significant differences (P value ranging from .0401 to .0033) in all efficacy parameters compared with placebo. The between-group comparison also revealed that MEC supplement had a significantly greater effect (P < .001) versus placebo. No investigation product-related AEs were reported. There were no clinically significant abnormalities in physical findings and no statistically significant changes in biochemical and hematological parameters, vital signs, body weight, and body mass index observed between the two groups at baseline and follow-up visits. MEC supplementation represents an effective and safe alternative to manage dyspepsia symptoms in FD patients.
