This is a pilot clinical study designed to evaluate the effects of a dietary supplement on selected blood-based nutritional biomarkers in healthy children aged 4 to 15 years. Approximately 24 children will be screened and enrolled to account for potential dropouts, with a target of 20 participants completing the study. Eligible participants will attend a screening and baseline visit, followed by daily intake of the study supplement for 4 weeks. After the supplementation period, participants will return to the clinic for an end-of-study visit. Blood samples will be collected at baseline and after 4 weeks to measure nutritional biomarkers, including vitamin D, vitamin B12, folate, omega-3 fatty acids, and standard blood count parameters. Additional assessments include height, weight, body mass index (BMI), and a socioeconomic questionnaire. Throughout the study, participants or their caregivers will record daily supplement intake, any medications taken, and any adverse events in a study diary. The results of this pilot study will provide preliminary data on the effects of the dietary supplement on serum biomarkers in children.
