Deadline: 28-Apr-2026
The Grand Challenges Addressing Physiological Barriers to Micronutrient Absorption from Fortified Foods provides up to $250,000 USD over 18 months for innovative solutions that improve the effectiveness of fortified foods. The initiative seeks proposals targeting biological constraints such as inflammation, gut dysbiosis, or metabolic conditions, emphasizing scalable, cost-effective, and measurable interventions for global populations.
Overview
This initiative supports innovative approaches to understand, measure, and overcome biological constraints that limit the absorption and utilization of micronutrients from fortified foods. It focuses on enhancing nutritional impact in populations where conventional fortification programs are insufficient due to physiological barriers.
Program Objectives
Proposals should:
- Identify how inflammation, infection, environmental enteric dysfunction, metabolic conditions, or gut dysbiosis limit micronutrient absorption.
- Define target populations and contexts where fortification is constrained.
- Provide a biological rationale and mechanistic understanding of absorption barriers.
- Offer innovative, testable solutions, such as novel fortificant formulations, adjunctive therapies, microbiome-modulating strategies, anti-inflammatory interventions, or gut-repair approaches.
- Develop or validate practical biomarkers for identifying or stratifying affected populations.
- Demonstrate feasibility, scalability, and integration into existing fortification platforms.
- Ensure cost-effectiveness suitable for low-resource settings.
- Include regulatory, supply chain, measurement, and evaluation considerations.
- Address equity and context relevance for high-burden populations.
- Present a capable multidisciplinary team able to translate discovery into scalable impact.
Eligibility and Scope
- Funding Amount: Up to $250,000 USD per project over 18 months.
- Eligible Applicants: Nonprofit organizations, for-profit companies, international organizations, government agencies, academic institutions; multi-stakeholder collaborations encouraged.
- Scope: Projects can be at any stage, including early-stage discovery, proof-of-concept, or new product ideas.
- Exclusions: Proposals focused solely on agricultural research, live biotherapeutics, public health data collection, policy, or marketing.
Targeted Physiological Barriers
The initiative seeks solutions addressing:
- Hepcidin-mediated iron blockade.
- Impaired fat-soluble vitamin absorption.
- Microbiome–nutrient interactions.
- Other inflammation or metabolic barriers limiting micronutrient uptake.
Why This Initiative Matters
Addressing physiological barriers is essential to:
- Unlock the full potential of fortification programs.
- Improve micronutrient status and nutritional outcomes.
- Accelerate equitable gains in global nutrition and health.
- Ensure fortified foods deliver intended benefits effectively, even in populations with high burdens of infection or undernutrition.
How to Apply
- Develop Proposal
- Include objectives, biological rationale, proposed solutions, target populations, and context relevance.

Common Mistakes to Avoid
- Proposing projects that focus solely on agriculture, marketing, policy, or live biotherapeutics.
- Neglecting to address biological constraints or provide mechanistic rationale.
- Failing to demonstrate feasibility, scalability, or integration with fortification platforms.
- Submitting budgets that do not include indirect costs or realistic cost estimates.
- Ignoring target population context and equity considerations.
