#VitaminB1

In a scientific breakthrough decades in the making, researchers have finally confirmed a “crazy” theory dating back to 1958 involving vitamin B1, or thiamine. By successfully stabilizing an extremely reactive molecule known as a carbene in water—something scientists long believed to be impossible—this team has not only resolved a long-standing biochemical debate but also unlocked new possibilities for sustainable chemical manufacturing around the world, including Thailand. Their results, published in Science Advances on April 11, 2025, have sparked fresh excitement in both academic and industrial laboratories worldwide (SciTechDaily).

In a major development that could transform both medicine and nutrition science, a team of chemists has successfully confirmed a decades-old theory regarding vitamin B1 (thiamine) — a feat once considered impossible. Their findings, detailed in recent reports, promise to sharpen understanding of how this vital nutrient functions at the molecular level, potentially opening new avenues for treating diseases and improving public health policy worldwide.

The breakthrough centers on the molecular mechanisms underpinning the biological activity of vitamin B1, a nutrient essential for nerve, muscle, and heart function. For years, scientists suspected that thiamine played a more sophisticated role within the body’s metabolic processes than previously confirmed, but technical barriers made it nearly impossible to observe and verify those processes in detail. The research team, leveraging advanced analytical techniques and state-of-the-art laboratory tools, have now provided the first direct evidence that supports these long-standing theories, upending conventional wisdom and energizing researchers around the globe.

In a historic breakthrough, scientists have finally confirmed a 67-year-old hypothesis about vitamin B1, also known as thiamine, radically advancing our understanding of how this crucial vitamin works in the human body. This finding not only settles a decades-old scientific debate but also unlocks new possibilities for eco-friendly chemical production, with potential impact reaching far beyond the laboratory.

The story of this discovery begins in 1958, when a chemist from Columbia University theorized that vitamin B1 might perform its vital metabolic functions through the formation of an elusive molecular structure called a carbene. Carbenes are notoriously unstable and tend to decompose instantly in aqueous (water-based) environments like the human body, making the hypothesis seem improbable for more than half a century. For years, the idea was dismissed as “crazy,” as quoted by Vincent Lavallo, a chemist at the University of California, Riverside, who led the recent research that validated this bold proposal.
