Summary
Thiamine is a highly underrated but very important vitamin for your gut health, mitochondria, immune system, and more. However, 56% of people aren’t getting enough. In this episode, I’ll explain the important function of thiamine, signs of deficiency, health conditions associated with it and how you can add more thiamine in your diet.

| 0:25.9 | Over 56% of people are not consuming enough thiamin or vitamin B1 in their diet. |
| 0:33.3 | Why this is so important is because we can't synthesize it. We're totally dependent upon dietary intake. |
| 0:39.4 | Not only that, but thiamine, B1, is depleted by stress, inflammation, and poor gut health. |
| 0:47.6 | This can lead to a self-feeding cycle wherein a lack of B1 in the diet is compounded by Cbo or fungal overgrowth, and then these, as they deplete |
| 1:01.1 | thiamine, actually alter motility and can further worsen problems in the gut. And so it's probably |
| 1:08.9 | no surprise that this is a somewhat common deficiency, but it also |
| 1:14.8 | seems to be overlooked. And part of this is because testing is notoriously inaccurate. So |
| 1:20.7 | health officials, if you will, are a little bit at a loss for how do we quantify this. But |
| 1:26.7 | let's have the discussion today so that if there is a simple vitamin solution |
| 1:32.1 | to some of the gastrointestinal and neurological symptoms that might be plaguing you, |
| 1:37.3 | then we can point you in the right direction along with a protocol. |
| 1:41.3 | So to start, let's answer the question, are you getting enough? |
| 1:45.8 | 2011 N. Haynes data, looking at over 16,000 individuals, assessed the nutrient intake of |
| 1:53.9 | thiamine in the diet. And they found that 56.3% were not consuming enough dietary thiamin, which is probably why a 2021 review paper |
| 2:06.7 | commented as follows. A large body of evidence dating back decades suggests thiamine deficiency |
| 2:14.1 | is neither rare nor limited to traditionally defined populations, but that it is |
| 2:21.2 | simply under-recognized. As a little bit of context, vitamin B1 was actually the first |
| 2:29.3 | vitamin ever discovered. It functions to allow the mitochondria, partially via the Krebs cycle, to make |
| 2:37.1 | energy, so cellular energy production. It also has important functions for the immune system. |
