The Juice Plus NIH study refers to a newly announced, large-scale clinical research collaboration focused on cognitive health and healthy aging. The project brings together three respected academic institutions:
This is not a marketing study or a small pilot project. It is a multi-year, internationally coordinated research program that meets the highest scientific standards in human nutrition and cognitive research, instilling confidence in the audience.
A Global, Multi-Year Research Collaboration
The collaboration operates within a US–Ireland R&D Partnership framework, with coordinated support across the United States, Ireland, and Northern Ireland. This structure alone signals seriousness, scale, and long-term commitment.
Why This Announcement Is Big News
The significance of the Juice Plus NIH study lies in the fact that it is not just who is involved, but also transparent research conducted with methods trusted by the scientific community, encouraging confidence in its credibility.
The National Institutes of Health (NIH) is widely regarded as one of the world’s most rigorous public funders of biomedical research. NIH support is competitive, peer-reviewed, and methodologically demanding.
UCLA’s Leadership and NIH Grant Support
In this study, NIH funding is tied specifically to UCLA’s leadership role in the research program. This means the study design, execution, and oversight meet NIH expectations for scientific rigor and accountability.
International R&D Partnership Framework
Alongside NIH involvement, additional public research support structures are described for Irish and Northern Irish partners, including research councils and health R&D bodies. The result is a coordinated international effort, not a single-site experiment.
One of the strongest credibility markers of the Juice Plus NIH study is its clinical trial design.
Randomized, Double-Blind, Placebo-Controlled
In simple terms, this means:
This is considered the gold standard in human clinical research because it minimizes bias and strengthens confidence in the results.
Who Is Participating in the Study
According to public trial registry information (ClinicalTrials.gov ID: NCT07226674), participants include:
The target enrollment is approximately 100 participants, with study timelines extending into 2028.
Juice Plus Berry Blend vs Placebo
The study evaluates Juice Plus Essentials Berry Blend Capsules compared to a micronutrient-matched placebo. Importantly, the company states it is providing the investigational product only and is not involved in study design, conduct, or data analysis, a key independence safeguard.
Study Timeline and Scale
The trial is listed as starting around late 2025, with completion expected several years later. This duration allows researchers to examine both short-term and longer-term biological and cognitive changes.
This is not a simple “do people feel better?” study. The Juice Plus NIH study reflects a modern, systems-biology approach.
Cognitive Performance and Executive Function
Participants undergo standardized cognitive testing, including:
MRI-related exclusions in eligibility criteria suggest brain imaging or biomarker rigor in parts of the protocol.
Microbiome and Polyphenol Metabolites
Researchers are also measuring:
These measures help explore mechanisms, not just outcomes.
One of the most exciting aspects of the Juice Plus NIH study is its focus on the gut–brain axis,the two-way communication between the digestive system and the brain.
Polyphenols from berries are metabolized by gut microbes into bioactive compounds. These metabolites may influence:
Studying these pathways helps scientists understand how nutrition might support cognitive health, not just if it does.
Berry and grape polyphenols are among the most researched plant compounds in nutrition science. They are known for:
Peer-reviewed studies have already characterized the composition and absorption profile of Juice Plus berry-based blends, making them a scientifically logical choice for further investigation.
While the Juice Plus NIH study is forward-looking, Juice Plus+ products have already appeared in peer-reviewed human clinical trials.
For example, a randomized, double-blind, placebo-controlled crossover study published in the journal Nutrients examined an encapsulated fruit, vegetable, and berry juice powder concentrate (identified as Juice Plus+ Premium®). The study explored cognitive performance measures and neuroprotective biomarkers.

The Juice Plus NIH study represents a meaningful step forward in nutrition and cognitive health research. Its strengths lie in who is leading it, how it is designed, and what it aims to measure.
By combining NIH support, respected universities, rigorous methodology, and modern biological endpoints, this study raises expectations for how nutrition research should be conducted and how responsibly it should be communicated.
