Adolescents' diets are key to breaking the intergenerational cycle of malnutrition. This study will guide policies and programs on the adequacy, acceptability, and feasibility of implementing balanced energy protein and multiple micronutrient supplementations to fill nutrient gaps in adolescent girls. Using a trial, the study will assess dietary intake and nutrient gaps, acceptability of balanced energy protein and multiple micronutrient supplementations. In addition to the trial, the study will the assess willingness to pay for the supplements and the most effective delivery platform and model to reach vulnerable adolescent girls. The most effective delivery platform and model to reach vulnerable adolescent girls cost-effectively will also be assessed through interviews with (inter)national experts, producers, and the donor community.

In low- and middle-income countries, it is estimated that each year, 21 million adolescent girls become mothers. Infants of adolescent mothers are at increased risk of delivering babies preterm, with low birth weight or length. Targeting nutrition interventions to improve adolescent girls' diet and nutrition is crucial to breaking the intergenerational cycle of poor growth and development. There is a specific need to assess how a balanced energy protein (BEP) and multiple micronutrient (MMN) supplement interventions can be tailored to adolescent girls and women of reproductive age.

This study aims to assess the adequacy, acceptability, and feasibility of implementing nutritional supplementations to fill nutrient gaps in adolescent girls in resource-limited settings. A trial will specifically:

1. assess the short-term acceptability of BEP and MMN supplements
2. assess how nutrition supplements increase nutrient adequacy of diets adolescent girls in resources-limited settings;

Using a qualitative component, the study explores the food agency of adolescents and the most effective delivery platform to reach vulnerable adolescent girls cost-effectively. The overall aim is to guide policies and programs on new formulations of nutritional supplements for adolescent girls in resource-limited settings.

The data will be transferred to the donor in a pseudo-anonymised way. After preparing a data-sharing agreement, the investigators will also share food intake data with the Food and Agriculture Organization and World Health Organization (FAO/WHO) of the United Nations Global Individual Food Consumption Data Tool. All research output generated by the project is open access as part of the Grant Agreement with the funder. Given the personal nature of the data, individual data will only be shared after a data transfer agreement with third parties. The informed consent form mentions that data can be shared outside the study team.

Individual participant data will be shared after data cleaning and quality checks are completed. All study other study materials will be shared after the finalization of the data collection.

Personal data will only be shared under a data sharing agreement, subject to approval by the relevant authorities. The transfer will only be performed in the public interest, which means that it will increase knowledge and insight to society's direct or indirect benefit.
