Alzheimer’s disease affects millions of families across the United States, creating an urgent need for effective treatments that can slow cognitive decline. While there is currently no cure, researchers are actively investigating compounds that target the underlying mechanisms of the disease. One of the most promising areas of study involves metabolic therapies that support brain energy processing.
Rutgers Health, in collaboration with the National Alzheimer’s Disease Cooperative Study, has launched a clinical trial to evaluate the efficacy of benfotiamine—a synthetic version of Vitamin B1 (thiamine)—in slowing the progression of Alzheimer’s. This initiative places Rutgers University–Camden and its affiliated medical research teams at the forefront of neurodegenerative research.
Understanding the Role of Thiamine in Brain Health
To understand why researchers are focusing on Vitamin B1, it is necessary to look at how the brain processes energy. The brain relies heavily on glucose as its primary fuel source. In patients with Alzheimer’s disease, brain cells often struggle to metabolize glucose efficiently, leading to cellular stress and eventual death.
Thiamine is a critical coenzyme in the metabolic pathways that convert glucose into energy. Deficiencies in thiamine are known to cause neurological damage, and post-mortem studies have shown that individuals with Alzheimer’s often have lower levels of thiamine-dependent enzymes in their brains. The trial seeks to determine if boosting thiamine levels can reverse or mitigate this energy deficit.
The Science Behind Benfotiamine
Standard thiamine supplements are not easily absorbed by the body, which limits their therapeutic potential. Benfotiamine is a lipid-soluble form of thiamine that is significantly more bioavailable. It can increase blood thiamine levels up to 100 times higher than normal.
Beyond simply providing fuel, benfotiamine appears to combat the pathology of Alzheimer’s through several mechanisms:
- Reducing Inflammation: Chronic inflammation is a hallmark of neurodegenerative disease, and benfotiamine has demonstrated potent anti-inflammatory properties.
- Preventing Protein Buildup: The compound helps reduce the accumulation of harmful compounds that stick to proteins, forming the plaques and tangles characteristic of Alzheimer’s.
- Protecting Nerve Cells: By mitigating metabolic stress, benfotiamine may help preserve the integrity of nerve cells longer.
Details of the Rutgers Health Clinical Trial
The current study is a Phase 2 clinical trial, which focuses on determining the drug’s effectiveness and optimal dosing. It is an 18-month, federally funded study taking place at approximately 40 sites across the United States, with Rutgers serving as the exclusive site in New Jersey.
Study Design and Methodology
The trial utilizes a rigorous scientific approach to ensure accurate results. Participants are randomly assigned to receive either a placebo or benfotiamine capsules taken twice daily. The study is double-blinded, meaning neither the participants nor the researchers know who is receiving the active treatment until the trial concludes.
Throughout the 18-month period, participants undergo regular evaluations, including:
- Standardized memory and cognitive tests.
- Regular blood work to monitor thiamine levels and overall health.
- MRI scans to observe structural changes in the brain.
Who is Eligible to Participate?
Researchers are actively recruiting individuals between the ages of 50 and 89 who are experiencing mild memory concerns or have received a diagnosis of early-stage Alzheimer’s disease. Eligible participants must be stable on their current medications for at least three months prior to enrollment. Individuals living at home or in assisted living facilities are welcome to apply, provided they have a study partner to assist them throughout the process.
Building on Promising Pilot Data
This large-scale trial is not starting from scratch. It builds upon a 12-month pilot study published in the Journal of Alzheimer’s Disease in 2020. That initial study, which involved 35 participants, found that benfotiamine was safe and well-tolerated. Most importantly, the results suggested a slowed rate of cognitive decline among those taking the supplement compared to those taking a placebo.
These findings provide a strong foundation for the current, more comprehensive investigation. If the results are replicated, benfotiamine could become a standard, low-cost adjunct therapy for managing early-stage Alzheimer’s.
The Broader Impact on Alzheimer’s Research
Research initiatives like this highlight the importance of academic medical centers in advancing patient care. By participating in national cooperative studies, institutions like Rutgers Health contribute data that shapes the future of treatment protocols worldwide.
For students and aspiring medical professionals, this trial exemplifies the intersection of clinical geriatrics, pharmacology, and neuroscience. It demonstrates how targeted metabolic interventions can offer new hope where traditional approaches have struggled.
How to Get Involved
Clinical trials are essential for medical progress, but they rely entirely on the willingness of volunteers to participate. By joining studies like the one at Rutgers, patients not only gain access to potential new treatments but also contribute to a legacy of care that will benefit future generations.

Next Steps for Families
While waiting for new treatments to become available, families affected by Alzheimer’s should maintain open communication with healthcare providers. Discussing the potential of metabolic therapies and staying informed about clinical trials can provide a proactive approach to managing the disease.
