High-dose thiamine is not always about correcting a simple dietary deficiency. This clip explains how very large doses may help reactivate thiamine-dependent enzymes that have become blocked or impaired, allowing cells to produce energy more effectively. The discussion also points to traumatic brain injury research showing how restoring B1-dependent energy pathways may reduce secondary cellular damage.

A normal thiamine blood test does not necessarily mean your cells have enough B1. This clip explains why serum and plasma thiamine mainly reflect what is circulating in the blood recently, not what is actually happening inside your cells, and why relying on those results alone can create a false sense of security.

High-dose thiamine can sometimes help dramatically at first, then start producing completely different symptoms later. This clip explains why people correcting a B1 deficiency may eventually need to reduce the dose, especially if signs of sympathetic nervous system overdrive begin appearing after months of improvement.
