This clip breaks down why vitamin B1 deficiency does not just stay a B1 problem. Once digestion starts breaking down, the body loses the ability to properly digest food and absorb nutrients, which can trigger a much bigger cascade. That is when one deficiency starts turning into many. If someone is losing appetite, getting weaker, and slowly burning through their own reserves, this may be one of the hidden mechanisms behind it.

Before vitamin B1 deficiency becomes severe enough to look textbook, it can look like the kind of random problems people brush off every day. Slower digestion, acid reflux, constipation, bloating, fatigue, low motivation, needing more sleep, insomnia, numbness, tingling, mild burning sensations, and exercise intolerance. This clip breaks down why early B1 deficiency can hide behind symptoms that seem ordinary, which is exactly why so many people never realize what is really going on.

Most people only think about sugar when they think about what burns through vitamin B1. This clip looks at the other side of the equation, why refined vegetable oils and unstable polyunsaturated fats are also being blamed for increasing oxidative stress and adding to the body’s thiamine burden. If the modern diet is hitting B1 from both directions, refined carbs on one side and oxidized fats on the other, that changes the whole conversation.
