This foundation's mission is to reduce malnutrition through food fortification. It focuses on providing supplements — such as iodised salt — and healthy food to malnourished populations. The website includes downloadable fact sheets of GAIN's programmes around the world and overviews of vitamins and nutrient deficiencies.

The organisation targets vulnerable groups such as young children, pregnant women, people with infectious diseases, remote rural populations, or refugees. GAIN takes a business-minded approach to funding better nutrition, pooling its money with financial institutions, not-for-profit global venture funds and venture capitalists to encourage local businesses to develop new products, distribution channels and marketing approaches.

The Global Forum for Health Research provides evidence, tools and discussion forums for decision-makers in research funding and policy to improve the health of the poor. Although it covers issues for both infectious and non-communicable diseases, the agency recognises that mental health problems are severely neglected in developing countries. As well as links to various publications and reports, the website also hosts RealHealthNews, which aims to share news on research and interventions that can improve the health of those in developing countries.
