2023 Trends in Functional Nutrition

2023 functional nutritional trends reveal what consumers want from functional products and why. They also point to key opportunities, including functional snacks, sleep support products, and more.


  • Interest in functional nutrition is growing globally as consumers seek to boost health.
  • The latest trends cover the top functional ingredients and health benefits.
  • Several opportunities are emerging in claims and formats.

What Is Functional Nutrition?

Functional nutrition describes food and beverage products that contain bioactive ingredients to support a specific health or wellness goal. These products range in format from bars to beverages and typically feature benefit claims that go beyond what basic nutrition can provide.

Innova reports that consumer interest in functional nutrition is rising across the globe.1 When Innova asked consumers about healthy eating, more said their main approach is “to choose products that positively boost my nutrition or benefit how my body functions” compared to the prior year (+4 ppt in Canada and Brazil, +5 ppt in the US and China, and +10 ppt in Spain and Mexico.2

How Consumers Use Functional Nutrition

While functional nutrition can address a variety of consumers’ needs—from exercise recovery to mental focus—the top reason consumers are reaching for functional nutrition products is to boost health. In the past 12 months, 29.3% of consumers globally have chosen foods and beverages with a health-boosting ingredient to improve their physical health, and 24.9% say it’s for a specific health condition.3

Generational Differences

Innova reports generational differences in the use of functional nutrition, with younger consumers driving the trend.4 For consumers aged 18-34, choosing products that boost nutrition or benefit how the body functions is the key approach to healthy eating for nearly one in three.5 Only one in five say limiting bad-for-you products and ingredients is their main approach, while it’s the top approach for those 55 and over.6

Types of Functional Ingredients Consumed

The most commonly consumed functional ingredients include caffeine (55%), electrolytes (30%), and antioxidants (28%).7 These are fairly mainstream and can be found in many everyday foods and beverages, as well as in functional products. Ingredients newer to the functional food and beverage industry such as prebiotics (15%), melatonin (11%), and adaptogens (7%)8 are likely to have more niche audiences looking for those health benefits.

Opportunities in Functional Nutrition Products

1. Heart Health and Sleep Support

Recent data points to some key opportunities for brands in functional nutrition. When comparing function desirability with current consumption, heart health and sleep support stand out as having the highest growth potential, notes Innova.12 Focusing on well-known functional ingredients, effective messaging, and convenient formats (like beverages and snacks) can help grow these segments.

About one in four Gen Z consumers and one in three Millennial, Gen X, and Boomer consumers say a protein claim influences their purchase decision of sports and functional nutrition products.16 Claims about the functional ingredients are influential to nearly one in four overall.17
