Researchers discovered something unusual when thiamine interacted with sulfur compounds in garlic. It formed allithiamine, a thiamine derivative capable of crossing cell membranes differently from ordinary B1. This clip explains why that discovery mattered, how it allowed thiamine to bypass normal transport limitations, and why getting B1 into the cells and brain more efficiently became such an important part of thiamine research.

Some people feel tired, groggy, or noticeably worse when they try adding carbohydrates back after spending a long time low carb. This clip explores the role thiamine may play in that response. Because B1 is essential for processing glucose and turning it into usable energy, increasing thiamine may help restore the body's ability to handle carbohydrates efficiently and regain metabolic flexibility.

When thiamine deficiency becomes severe, the body can lose its ability to process glucose efficiently through the mitochondria, pushing more pyruvate toward lactate and, in extreme cases, contributing to lactic acidosis. This clip explores the metabolic similarities with the Warburg effect, where cancer cells rely heavily on glycolysis and produce large amounts of lactate despite abundant glucose. At the center of the discussion is pyruvate dehydrogenase, a critical gateway between glucose metabolism and mitochondrial energy production.
