Growth Drivers for the North America Dietary Supplement Market

1. Increasing Health Awareness and Preventive Healthcare Trends

Consumers in North America are increasingly focused on preventive healthcare. Awareness about nutrition and chronic disease prevention drives demand for vitamins, minerals, herbal supplements, and functional nutrition products.

Supplements for immune support, cardiovascular health, mental function, and energy management are particularly in demand.

Natural, plant-based, and clean-label offerings have gained popularity due to consumer preference for organic and sustainable solutions.

In May 2024, Bayer launched a “One A Day” social media campaign with former NFL star Julian Edelman to promote wellness education and counter misinformation. Initiatives like this highlight the rising consumer interest in science-based health solutions.

2. Aging Population and Nutritional Deficiencies

North America has a rapidly aging population, with a large proportion of consumers above 50 years of age. Older adults are prone to nutritional deficiencies due to changes in metabolism, restricted diets, or medical conditions. Key nutrients include:

Calcium & Vitamin D – for bone health

Omega-3 fatty acids – for cardiovascular and brain function

The UN predicts the population aged 60+ in North America will rise from 79 million in 2017 to 123 million by 2050, which is driving demand for specialized supplements for healthy aging and overall wellness.

3. Expansion of E-Commerce and Personalized Nutrition

The growth of online retailing has expanded access to dietary supplements. Consumers can now explore product ratings, reviews, and personalized recommendations.

Nutrigenomics and personalized nutrition allow consumers to receive tailored supplements based on genetic profile, lifestyle, and health objectives.

Subscription models and direct-to-consumer brands offer convenience and personalized solutions for a tech-savvy, health-conscious demographic.

For instance, in November 2024, Persona Nutrition introduced a white-label solution enabling other brands to enter the personalized supplement space using its expertise.
