Rising Consumer Interest in Personalized Health: There is a noticeable shift in consumer preferences toward health solutions that are tailored to their individual needs. People are becoming more proactive about their health and are seeking customized dietary advice rather than generic recommendations. This trend is fueled by a desire to optimize well-being and prevent health issues based on their unique biological makeup.

This growing demand is supported by studies highlighting the potential of personalized approaches. For example, a 2024 review titled "Personalized Nutrition: Tailoring Dietary Recommendations through Genetic Insights" published in PMC (PubMed Central) emphasizes how individual genetic profiles can guide tailored dietary recommendations, potentially optimizing health outcomes and managing chronic diseases more effectively. This strong interest in custom-fit health strategies propels the growth of the U.S. nutrigenomics market.

Increasing Prevalence of Chronic Diseases: The widespread prevalence of chronic diseases in the U.S. is a major factor boosting the U.S. nutrigenomics market expansion. Conditions such as heart disease, diabetes, chronic obstructive pulmonary disease, and obesity place a substantial burden on the healthcare system and individuals. There is a growing understanding that diet plays a critical role in the development and management of these long-term health issues. Nutrigenomics offers a promising avenue for prevention and personalized treatment by identifying gene-diet interactions that can influence disease risk.

According to data from the CDC, as reported in the Chronic Disease Indicators: 2022–2024 Refresh and Modernization of the Web Tool published in 2024, six out of 10 adults in the U.S. have one chronic disease, and four out of 10 have two or more. These chronic conditions account for a significant portion of the nation's annual healthcare costs. This alarming public health challenge underscores the critical need for advanced, personalized nutritional interventions, which are driving the expansion of the U.S. nutrigenomics market.

Segmental Insights

Application Analysis

Based on application, the U.S. nutrigenomics market segmentation includes obesity, cardiovascular diseases, cancer research, and others. The obesity segment held the largest share in 2024. Nutrigenomics offers a personalized approach to weight management by identifying how an individual's genetic makeup influences their metabolism, appetite, and response to different diets. This allows for the creation of highly customized nutrition plans that are more effective than generic advice. As people seek more effective and sustainable solutions for weight reduction, the application of nutrigenomics in addressing obesity continues to expand, contributing significantly to its dominant position.

The cancer research segment is anticipated to register the highest growth rate during the forecast period. This rapid expansion is driven by a growing understanding of the complex interplay between diet, genes, and cancer development. Researchers are increasingly using nutrigenomic principles to explore how specific nutrients or dietary patterns can influence gene expression related to cancer prevention, progression, and treatment outcomes. The immense potential for personalized dietary interventions to reduce cancer risk or support existing therapies is fueling substantial investments and innovation in this area. This focus on precision nutrition in oncology is poised to drive remarkable growth in the cancer research application of nutrigenomics.

Product Analysis

Based on product, the U.S. nutrigenomics market segmentation includes reagents & kits and services. The reagents & kits segment held a larger share in 2024. These products are essential for conducting the initial genetic tests required for nutrigenomic analysis. Reagents, such as DNA sequencing, extraction kits, and PCR reagents, and various testing kits are fundamental tools used by research institutions, diagnostic labs, and even direct-to-consumer companies to collect and process genetic samples. The increasing availability and ease of use of these kits, especially with the rise of at-home testing, contribute significantly to their dominant position. Consumers and healthcare providers rely on these foundational products to gather the genetic insights needed to develop personalized nutrition plans, thus solidifying their market share.

The services segment is anticipated to register a higher growth rate during the forecast period. This rapid expansion is driven by the growing need for expert interpretation of complex genetic data and the demand for personalized dietary counseling. While reagents and kits provide the raw genetic information, it's the services that translate this data into actionable, tailored nutrition plans and ongoing support. As the understanding of nutrigenomics becomes more sophisticated, so does the need for professional guidance, including genetic counseling, personalized diet planning, and long-term nutritional advice. This comprehensive support, which extends beyond just testing, is becoming increasingly valued by consumers seeking to truly integrate nutrigenomic insights into their health management, thereby propelling the services segment to strong growth.

Technique Analysis

Based on technique, the segmentation includes saliva, buccal swab, and blood. The saliva segment held the largest share in 2024. This method is highly preferred due to its noninvasive nature and ease of collection, making it a comfortable option for consumers.
