CFAs: Global Grants for Gut Health Research

Deadline: 14-Jul-2026

The Global Grants for Gut Health is a competitive international funding programme for investigator-led research on the human gut microbiota. It is designed to advance understanding of how the gut microbiome affects human health, especially through the gut–brain axis.

The programme supports both laboratory and clinical research projects, with a strong focus on mechanistic studies and potential therapeutic targets. It is intended for independent researchers at eligible host institutions worldwide.

Key facts

• Funder: Jointly supported by Yakult and Nature Portfolio.

• Grant type: Investigator-led research grant.

• Project duration: Up to 1 year or 12 months.

• Funding level: Up to USD 100,000 in direct research costs.

• Overhead: Up to 10% of direct costs, capped at USD 10,000.

• Geography: Global.

• Eligibility: Researchers worldwide, subject to legal and sanctions restrictions.

• Submission: Through the Nature Portfolio Submittable application system.

What the grant supports

The programme supports research on the human gut microbiota, with emphasis on:

• Gut–brain axis mechanisms.

• Neurotransmitter production.

• Immune signalling.

• Stress responses.

• Cognition and mood.

• Neurological function.

It is especially interested in conditions such as:

• Depression.

• Anxiety.

• Autism spectrum disorder.

• ADHD.

• Parkinson’s disease.

• Alzheimer’s disease.

Both basic and clinical approaches are welcome if they contribute to understanding the biological pathways linking gut microbiota and human health.

Who is eligible

Applicants must generally:

• Hold a doctoral or medical degree such as PhD, MD, or equivalent.

• Have at least five years of postdoctoral research experience.

• Be employed by a university, research institute, or other not-for-profit organisation.

• Be able to lead an independent research project.

• Have a strong record of research excellence.

The principal investigator must be affiliated with an eligible host institution. Applications are open to any nationality, subject to legal and sanctions-related restrictions.

Where projects can be hosted

Eligible host institutions are worldwide, except in:

• Cuba.

• Iran.

• North Korea.

• Russia.

• Belarus.

• Crimea.

• The occupied territories of Ukraine.

• Other locations restricted by law.

What the funds can cover

Eligible direct costs include:

• Salaries.

• Research materials.

• Travel.

• Publication costs.

• Ethical approvals.

• Licences.

• Consultancy fees.

• Subcontracting.

The funding is intended only for research activities. It cannot be used for training, education, networking, or commercial development.

What makes a strong proposal

A competitive application should show:

• A clear scientific question about gut microbiota and human health.

• Strong relevance to the gut–brain axis or a related mechanism.

• Originality and mechanistic insight.

• Feasibility within one year.

• A capable independent PI and suitable host institution.

• Clear methods and measurable outputs.

• A strong case for scientific merit and translational relevance.

How the review works

Applications are reviewed in two main stages:

1. Scientific screening for quality and originality.

2. Final assessment by an international expert panel in gut microbiota research.

The final decision is made independently by the expert panel, based on scientific merit and relevance to human gut microbiota.

Reporting and obligations

Awardees are expected to:

• Submit a mid-term report.

• Acknowledge the funding in publications and outputs.

• Disseminate results through academic channels.

• Retain intellectual property within the host institution.

Why it matters

The gut microbiome is increasingly recognized as a major influence on health, including brain function and mental well-being. This grant matters because it supports short, focused projects that can produce timely and meaningful insight into gut–brain biology.

It is especially valuable for researchers who want to test a precise hypothesis or generate pilot data for larger studies.

Common mistakes and tips

• Mistake: Proposing a project that is too broad for one year.

  • Tip: Focus on one tight, testable question.

• Mistake: Emphasizing general wellness rather than microbiome biology.

  • Tip: Keep the project anchored in gut microbiota mechanisms.

• Mistake: Using the grant for training or networking.

  • Tip: Make sure the budget supports only research activities.

• Mistake: Weak host-institution fit.

  • Tip: Ensure the PI’s affiliation and institutional support are clear.

• Mistake: Vague translational relevance.

  • Tip: Explain how the project advances understanding of human health or disease.

FAQ
