As the global focus on health and wellness grows, understanding search trends for dietary supplements offers invaluable insights into consumer behavior. Leveraging two datasets—one detailing regional search volumes and the other illustrating temporal trends—we’ve identified critical patterns shaping the supplement industry.
1. Categorizing Search Queries Using AI
We used the Trajaan search intelligence software to reveal search volumes across cities in the United States for various dietary supplements. By analyzing this data, we identified the top categories of interest and products driving consumer engagement.


Top Supplements by Search Volume:
- Magnesium dietary supplement leads the pack with robust search interest across the U.S.
- Iron supplements, vitamin D, and ashwagandha gummies are also strong contenders in the dietary wellness space.
- Collagen products, especially those targeting hair growth, have demonstrated significant popularity.
These findings indicate that consumers are increasingly focused on supplements that address specific health concerns such as bone health, energy levels, and beauty-related benefits.
What this tells us: There’s a distinct shift toward functional supplements targeting multiple facets of wellness.
2. Major Trend Detection: Shifts in Consumer Behavior
To better understand how consumer behavior is evolving, we delved into quarterly search volume data spanning 2021 to 2024. Here are some significant findings:
a. Rapid Growth in Specific Products
Certain supplements have seen an exceptional surge in interest:
- Ashwagandha gummies experienced explosive growth, reflecting a heightened focus on stress management and adaptogens.
- Magnesium supplements maintained steady growth, likely tied to its role in mental health and muscle recovery.



b. Seasonal Patterns and Emerging Trends
- Products like collagen and vitamin D supplements displayed notable seasonality, peaking in winter months when skin health and immune support are priorities.
- The rise in searches for rosemary oil for hair growth and other topical solutions highlights a growing interest in natural beauty remedies.


c. Supplements with Declining Growth
While many products are thriving, some categories, such as generic multivitamins, have seen stagnant or declining interest, possibly as consumers pivot toward targeted and personalized supplements.

3. Geo-Based Trend Analysis: Uncovering Local Outliers in the USA
The regional search data shed light on localized trends and variations in consumer demand. Here are the standout findings:
a. Top Cities Driving Demand
- New York, Los Angeles, and Chicago lead the nation in search volumes for dietary supplements, reflecting their large, health-conscious populations.
- Cities like Houston and Seattle also demonstrate strong interest, likely tied to their wellness-oriented cultures.

b. Unique Regional Preferences

What Does This Mean for Brands and Agencies?
These findings hold critical implications for stakeholders in the supplement industry:
- Targeted Marketing Campaigns: Focus on cities like New York and Los Angeles for maximum impact while leveraging the rise of plant-based products in smaller, niche markets.
- Seasonal Strategies: Use search seasonality to time campaigns for collagen and vitamin D in winter months.
