Benfotiamine Absorbs Better Than B1, But Is That Enough?
Benfotiamine gets far more vitamin B1 into your system than regular thiamine, so you might expect it to work much better for nerves. Early short-term studies were encouraging, but in longer trials, including a recent 12-month study at 600 mg a day, thiamine levels rose substantially while nerve outcomes did not separate from placebo. In this video, Dr. Fitz explains what benfotiamine does, what the research shows, and the bigger lesson: better absorption doesn't automatically mean better results, and nerve health rarely comes down to one pathway or one ingredient. He also covers three questions to ask about any nerve supplement and why addressing the underlying cause still matters most. He discloses his financial interest in NeuroAxis in the video.
What you'll learn in this video
- Why regular thiamine absorption is limited, and how benfotiamine gets around it
- What early short-term benfotiamine trials found
- What the longer 2-year and 12-month trials showed, and why raising blood levels isn't the same as nerve repair
- Why nerves depend on several things at once: energy, blood flow, nutrients, and oxidative balance
- Three questions to ask about any nerve supplement: form, dose, and human evidence
- Why blood sugar, deficiencies, alcohol, and compression still need to be addressed directly
