Filter by:The aim of this study is to perform a double-blind, randomised, dose-response trial of vitamin D3 supplementation in United Kingdom (UK)-dwelling adults of white European, South Asian, and black African/Caribbean ethnicity to investigate the distribution of dietary intakes needed to maintain adequate vitamin D status in winter, as indicated by serum 25(OH)D concentrations at ranges of >25 to 50 nmol/L. In addition, this study will investigate the effect of vitamin D3 supplementation on immune health, muscular strength, and overall health.
The purpose of this study is to evaluate the impact of 28-day supplementation with high-dose human recombinant lactoferrin, low-dose human recombinant lactoferrin, and an active control product formulated with bovine lactoferrin on indicators of immunity in healthy males and females.
The primary objective of this study is to investigate the effect of an oral probiotic (Bacillus sp. spore preparation) on abdominal bloating, flatulence, and burping in generally healthy adults. Secondary outcomes include intestinal barrier integrity and fecal microbiome properties (taxonomical structure, diversity, and function).
The COVID-19 pandemic highlights the importance of good nutritional status for immune strength and for reducing comorbidities that increase morbidity and mortality of infections. The major aim of this study is test if almond consumption can improve immune function.
The primary objective of this study is to investigate the effect of a novel Bacillus subtilis spore preparation on abdominal bloating, flatulence, and burping in healthy adults.
Psychosocial and lifestyle factors in Army recruits likely contribute to increased susceptibility to infection and injury during basic Army training. The primary aim of this study is to assess the influence of psychosocial and lifestyle factors at the start of basic Army training on immune health (e.g. respiratory infection and antibody response to influenza vaccination) and injury during training, in an observational design. A secondary aim is to establish whether changes in psychosocial and lifestyle factors during training impact immune health (e.g. response to hepatitis B vaccination). Using an interventional design, participants will be randomly allocated into two experimental groups: (i) Routine vaccination group: to receive first hepatitis B vaccination at initial medical assessment upon entry to basic training and second hepatitis B vaccination 1 month later; (ii) Delayed vaccination group: to receive first hepatitis B vaccination during week 5 of training and second hepatitis B vaccination 1 month later.
to assess the efficacy and safety of a standardized Withania somnifera extract (Sensoril®) as an immunomodulator in individuals suffering from recurrent URTIs. The study population will be administered with this unique blend of WS extract for 12 weeks and will be assessed as per the study designated efficacy and safety variables.
This is a randomized, double-blind, placebo-controlled study to evaluate the impact of bovine Lactoferrin (bLf) on respiratory tract infections (RTIs) in an elderly population in the United States.
