A Clinical Trial to Evaluate the Effects of a Children's Daily Multivitamin on Perceived Growth, Immune Health, Energy, and Focus in Children

This is a single-group, open-label, fully decentralized (virtual) clinical trial evaluating the effects of the Hiya Kids Daily Multivitamin on parent/caregiver-perceived growth and development, immune health, daily energy, focus, and overall well-being in generally healthy children aged 3-12 years over an eight-week supplementation period. Enrolled children will receive one Hiya Kids Daily Multivitamin chewable tablet administered once daily with the first meal of the day for eight consecutive weeks. Parents or caregivers will complete study-specific questionnaires at Baseline, Week 2, Week 4, Week 6, and Week 8, and a product acceptability assessment at Week 8. All assessments are completed remotely via the study platform. Forty participants will be enrolled.

Psychological and Lifestyle Factors on Health Outcomes

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.

Effectiveness of Microdosed GLP-1 in Improving Health, Quality of Life, and Longevity Measures

The goal of this clinical study has two objectives. The Primary Objective is to evaluate the effectiveness of microdosed GLP-1 receptor agonists in improving measures of health, quality of life, and longevity. The Secondary Objective: To assess the impact of these therapies on weight management practices and metabolic health.

Estimation of the Dietary Requirement for Vitamin D in Ethnic Groups

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.
