Unlocking the Power of Vitamins and Supplements: YouTube’s Key Role in AI-Driven Research

A recent study conducted by Searcherries revealed that YouTube was the most commonly referenced website in Google AI Overviews for searches related to vitamins and supplements. The research, which monitored 50 daily searches from August 30 to September 5, 2026, found that YouTube appeared in 53.1% of the 350 AI-generated answers analyzed, making it the top-cited website in the study.

The analysis also highlighted other frequently cited websites in AI Overviews, with GoodRx coming in second at 48.3%, followed by Healthline at 28.6%, Cleveland Clinic at 28.0%, and the National Institutes of Health domain (nih.gov) at 25.1%. YouTube’s presence was particularly strong in searches related to “vitamins for,” appearing in 78.6% of those queries, almost twice as often as Healthline across the entire dataset.

Interestingly, the research discovered that AI Overviews often referenced pages that were not part of the organic search results. Only 32.4% of cited pages were found in the organic listings, while 67.6% were not. Matching citations by website instead of exact page increased the overlap to 52.5%, indicating that some AI references directed users to different pages on websites already present in organic search results.

The study also noted variations in the consistency of cited pages within individual queries. For example, in searches related to “supplements for weight loss,” nih.gov and YouTube were consistently cited, while other websites appeared intermittently. Conversely, searches related to “supplements to help with glp-1 side effects” consistently returned the same cited pages throughout the week.

Searcherries conducted the research by monitoring a fixed set of 50 Google Autocomplete queries daily, focusing on US English desktop results configured for New York. The analysis encompassed 350 AI Overviews, 5,036 citation occurrences, and 572 distinct pages across 218 websites. Organic overlap was calculated within each search, considering repeated citations to the same page only once.

In conclusion, the study shed light on the prevalence of YouTube in Google AI Overviews for vitamin and supplement searches, indicating the platform’s significant influence in providing information on these topics. The findings also underscored the importance of considering AI-generated summaries alongside traditional organic search results when seeking information online.
