NCT ID: NCT06067477 Recruiting - Clinical trials for Vitamin D Deficiency

Estimation of the Dietary Requirement for Vitamin D in Ethnic Groups

Start date: October 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06012669 Completed - Immune Health Clinical Trials

Effects of Lactoferrin at Two Doses vs. Active Control on Markers of Immune Function

Start date: September 6, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05595980 Completed - Clinical trials for Gastrointestinal Health

The Effects of a Novel Probiotic on Gastrointestinal Health in Generally Healthy Adults

Start date: September 19, 2022
Phase: N/A
Study type: Interventional

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).

NCT ID: NCT05059639 Active, not recruiting - Immune Health Clinical Trials

Exploring the Role of Almonds in Enhancing Immune Strength

Start date: November 15, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05004454 Completed - Clinical trials for Cardiovascular Health

Effect of Bacillus Subtilis BS50 Supplementation on Gastrointestinal Symptoms in Healthy Adults

Start date: July 19, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04780867 Completed - Stress Clinical Trials

Psychological and Lifestyle Factors on Health Outcomes

Start date: October 19, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04733924 Completed - Immune Health Clinical Trials

Efficacy and Tolerability of Sensoril® in Improving Immunity and Thereby Reducing Incidence of Upper Respiratory Tract Infections

Start date: January 21, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04713735 Completed - Immune Health Clinical Trials

Impact of Lactoferrin, a Dietary Supplement, vs. Placebo on Respiratory Tract Infections

Start date: February 8, 2021
Phase: N/A
Study type: Interventional

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.
