Omega-3 DHA Deficiency – An Underrecognized Public Health Challenge in Saudi Arabia
Omega-3 fatty acids, particularly docosahexaenoic acid (DHA), are crucial for maintaining brain function, cardiovascular health, and reducing risks of depression and dementia later in life. However, despite the known benefits, many populations worldwide, including those in Saudi Arabia, suffer from inadequate omega-3 intake. This insufficiency primarily arises from low consumption of fish and other omega-3-rich foods.
In Saudi Arabia, the prevalence of omega-3 deficiency is exacerbated by dietary habits and the limited availability of diverse food sources rich in DHA. Given the country's rising rates of cardiovascular disease and related non-communicable diseases, addressing this nutritional gap is more urgent than ever. The Human Nutritional Intervention Study tackles this critical challenge by exploring an innovative solution: enriching everyday foods like chicken and eggs with omega-3 DHA, thus making it easier for consumers to boost their intake without radical dietary changes.
Moreover, this deficiency underscores a public health concern that extends beyond individual risks. As the healthcare system grapples with the growing burden of chronic diseases, strategies promoting preventive nutrition become imperative. The study recognizes that sustainable interventions must be culturally acceptable, scalable, and aligned with local food production practices to ensure effectiveness and compliance.

The Study Design and Collaboration – A Confluence of Innovation and Scientific Rigor
The landmark intervention study involved 80 healthy Saudi adults who consumed omega-3 DHA-enriched chicken and eggs four times per week over a period of four months. These functional foods were enriched using Mara Renewables Corporation’s Humanativ 'OmegaProTM', a sustainable microalgae-based source of omega-3 DHA. This innovative approach represents a notable departure from traditional fish oil supplementation, emphasizing sustainability and scalability.
Participants’ omega-3 status was rigorously assessed through the Omega-3 Index, a biomarker reflecting the amount of EPA and DHA in red blood cell membranes. The index categorizes risk levels related to cardiovascular health, with values below 4% indicating very high risk, 4-6% high risk, 6-8% moderate risk, and above 8% low risk or desirable status. The baseline average Omega-3 Index among participants was approximately 4.75%, highlighting a widespread deficiency needing urgent attention.
Importantly, the study’s collaborative dimension brings together diverse expertise from King Abdulaziz University, RCSI University, Mara Renewables Corporation, and local producers Tanmiah Food Company and Arabian Farms. This synergy ensures that the research is grounded in scientific excellence, innovative technology, and practical food production realities. The involvement of Saudi Arabia’s leading producers underlines the feasibility of incorporating omega-3 enriched products into the nation’s mainstream food supply, thus complementing the country’s broader public health and nutrition goals.
Additionally, Mara Renewables Corporation’s cutting-edge approach—using microalgae fermentation to produce high-quality, fish-free algal omega-3 DHA—intersects health innovation with environmental sustainability. This method counters the challenges of overfishing and fish oil supply variability, simultaneously enhancing sensory qualities of enriched foods and ensuring consistent DHA levels.

Key Findings – Transforming Nutritional Deficits into Health Opportunities
The results of the intervention unequivocally demonstrated that consuming DHA-enriched chicken and eggs positively influences blood omega-3 levels. Participants who consumed these enriched products experienced a significant increase in their red blood cell Omega-3 Index by 0.9% compared to those in the control group. This improvement may seem modest but carries profound implications for cardiovascular and cognitive health risk reduction.
Strikingly, the intervention more than halved the number of individuals in the very high-risk category (Omega-3 Index < 4%), while the number with a protective Omega-3 Index (>6%) increased fourfold among participants consuming enriched foods. These shifts illustrate that integrating omega-3 DHA-enriched everyday foods can effectively mitigate the risks associated with low omega-3 status.
The study’s findings are corroborated by expert insights. Professor Pat Wall from University College Dublin highlighted that omega-3 DHA enriched chicken meat and eggs represent practical dietary solutions to improve public health. This assertion stresses a paradigm shift from nutritional supplements to integrated dietary sources as strategies to combat micronutrient deficiencies.
Moreover, the sustainability angle championed by Mara Renewables Corporation CEO Harry Boot demonstrates that innovation in food technology can play a dual role in enhancing human health and environmental stewardship. The production of algal omega-3 offers a sustainable, fish-free alternative that can be scaled globally, addressing universal health concerns without compromising ecosystems.
Furthermore, Tanmiah Food Company’s CEO Zulfiqar Hamadani emphasized the strategic importance of elevating the nutritional profile of poultry products. The initiative not only responds to immediate health concerns within Saudi Arabia but also aligns with the company’s vision of becoming a global leader in halal, sustainable, healthy protein by 2030. This represents a holistic approach blending nutritional science, consumer well-being, and sustainable corporate responsibility.

Implications for Public Health Policy and the Pathway towards Vision 2030
Beyond its scientific contributions, this study presents transformational opportunities for public health policies in Saudi Arabia. The widespread deficiency of omega-3 DHA among Saudi adults, coupled with existing high rates of cardiovascular disease, necessitates innovative dietary strategies that are accessible and acceptable at large scales.
The results from this intervention align with national frameworks like Saudi Arabia’s Vision 2030, which prioritizes well-being and quality of life alongside sustainable economic development. Introducing omega-3 DHA-enriched poultry products into the national food system could substantially reduce chronic disease risk factors, decrease healthcare burden, and improve population health outcomes.
Moreover, promoting the consumption of omega-3 enriched foods supports the Ministry of Health, Ministry of Environment Water and Agriculture, National Nutrition Committee, and Saudi Food and Drug Authority’s coordinated efforts to enhance nutritional standards. Such coordinated policy action would encourage local agricultural advances, minimize reliance on imported dietary supplements, and stimulate demand for nutritious, value-added products.
Dr. Salwa Albar, Associate Professor of Nutritional Epidemiology at King Abdulaziz University, highlighted that integrating functional, omega-3 DHA-enriched foods into everyday diets could bridge nutritional gaps, provide cardiovascular protection, and advance scientific nutrition strategies in public health. These insights underscore the necessity of embedding evidence-based nutritional innovations in policy frameworks designed to confront chronic disease epidemics through preventive care.
Furthermore, increasing consumer awareness of omega-3 enriched foods remains essential. Initiatives by Tanmiah and Mara Renewables Corporation to educate and market these products could dramatically enhance omega-3 DHA consumption nationwide. Ultimately, such efforts will support the Kingdom’s broader ambitions of fostering a healthier, sustainable population as part of its socio-economic transformation agenda.
