Biomarker-based nutrition has demonstrated superior efficacy compared to population-level approaches in improving health outcomes. Biofrequency analysis, a non-invasive technique based on the detection of electromagnetic vibrational patterns in hair follicles, offers a promising avenue for rapid functional assessment of nutritional status and epigenetic signals without reliance on blood or urine sampling. First, to evaluate the effect of a 90-day biofrequency-guided nutritional intervention on functional epigenetic status, as reflected in changes in the optimization report generated by the S-Drive system; second, to assess changes in adherence to the Mediterranean diet, anthropometric indicators, movement behaviors, and psychological well-being. Methods: In this randomized controlled trial, adults from a Sport Team from Region of Murcia (Spain) will be allocated to an experimental group receiving individualized lifestyle recommendations based on S-Drive biofrequency analysis and to a control group with no intervention. Participants in the experimental arm will apply tailored dietary guidance over 90 days. Conclusion: This study will generate foundational evidence on the utility of biofrequency technology for precision nutrition. If positive, the findings may inform scalable, low-risk strategies for personalized dietary interventions in preventive and community health settings.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants in this group receive a genetic hair analysis and a personalized nutritional follow-up based on the results. The aim is to assess whether the nutritional intervention modifies relevant genetic or biochemical markers after the intervention period.
Behavioral: Personalized Nutritional Follow-Up
Participants in this group receive a genetic hair analysis and are provided with the results only, without any nutritional follow-up. This group serves as a comparison to evaluate the effect of the nutritional intervention in the experimental group.
Participants in the experimental arm will receive a individual nutritional follow-up based on their epigenetic hair analysis results. This includes dietary guidance, recommendations tailored to genetic markers, and periodic consultations with a nutritionist over 4 weeks and continuous availability to clarify doubts via email . The aim is to evaluate changes in genetic expression or health biomarkers after the intervention period.
Change in biofrequency-derived epigenetic markers related to nutritional metabolism
This outcome evaluates the correlation between the nutritional intervention and functional epigenetic status, assessed through the S-Drive optimization report. The measurement tool is the S-Drive system (Cell Wellbeing, Germany), a non-invasive device that analyzes resonance frequency patterns from hair follicle samples using proprietary bioinformatic algorithms. The report classifies physiological function into 12 domains related to nutritional metabolism (e.g., micronutrients, oxidative stress, circulatory function), assigning ordinal values to each: "not flagged" (0), "to be considered" (1), "advisable" (2), or "priority" (3). Two derived quantitative variables will be analyzed: (1) the number of domains classified as "priority" (unit: count, range: 0-12), and (2) the cumulative optimization score summing the ordinal ratings (unit: score, range: 0-36). These biofrequency will be used to assess within-subject changes and between group correlations from baseline to 90-day follow-up.
Time frame: baseline and after 12-weeks post-intervention
Adherence to the Mediterranean Diet measured by the 14-item PREDIMED questionnaire
This outcome assesses adherence to the Mediterranean dietary pattern using the validated 14-item PREDIMED questionnaire (PREvención con DIeta MEDiterránea). Each item is scored as 0 (non-compliance) or 1 (compliance), for a total score ranging from 0 to 14. Higher scores indicate better adherence. The unit of measurement is the total PREDIMED score. A score ≥9 is considered high adherence. This variable will be measured at baseline and after the 90-day intervention to evaluate correlations between the individualized nutritional guidance and improvement in diet quality in the experimental group compared to the control group.
Time frame: Baseline and after 12 weeks of intervention
