Harmonized Micronutrient Project

This study has been completed.
Information provided by (Responsible Party):
Nestlé Identifier:
First received: March 26, 2013
Last updated: August 4, 2014
Last verified: August 2014
The purpose of this trial is to better define how individuals with different genetic make-ups will require different interventions to improve their methylation potential and nutrient status.

Condition Intervention
Dietary Supplement: micronutrient supplementation

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: A New Strategy to Analyze Gene-Nutrient Interaction in Children and Adolescents

Further study details as provided by Nestlé:

Primary Outcome Measures:
  • SAM/SAH ratio [ Time Frame: baseline and after 6 weeks of product intake ]
    Change from baseline in the correlation between the SAM/SAH ratio in erythrocytes, dietary intakes and, polymorphisms in genes associated with micronutrients

Secondary Outcome Measures:
  • SNP arrays, proteomics, metabolomics, micronutrient levels [ Time Frame: baseline, after 6 weeks of product intake and after 6 weeks of follow up ]
    Composite secondary outome: extensive "omic" analysis and correlation of the data over the 3 timepoints

  • SAM/SAH ratio [ Time Frame: after 6 weeks product intake and after 6 weeks of follow up ]
    Change between 6 weeks after product intake and 6 weeks of follow up in the correlation between the SAM/SAH ratio in erythrocytes, dietary intakes and, polymorphisms in genes associated with micronutrients

Enrollment: 146
Study Start Date: March 2013
Study Completion Date: June 2014
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: micronutrient supplementation

All the enrolled subjects will recieve orally, onca a day, during school days a chocolate bar including vitamins and minerals.

The micronitrient supplementation will be consumed over 6 weeks, 5 days/week.

Dietary Supplement: micronutrient supplementation
Other Name: Nestrovit: white chocolate bar with vitamins and minerals

Detailed Description:

Despite the increasing incidence of overweight and obesity among children, nutritional deficiencies are still a concern.

A low intake of vitamins and minerals is associated with a reduction in the antioxidant capacity. Some vitamins are associated with chronic diseases including overweight and obesity.

S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) are the substrate and product of essential reactions; the SAM:SAH ratio has been associated with health and is an indicator of cellular DNA methylation potential.

Low level of this ratio may affect short and long term health. In this explorative knowledge building open interventional study, subject to be enrolled are children or adolescents 9 to 13 years of age per year (n=180 per year, over 2 years). The study consists of 6 weeks nutritional intervention followed by a 6 weeks follow up.

In this study, genomics, proteomics, lipidomics analysis will be performed, in addition to biochemistry, hematology and vitamins analysis.
