Brain fog at work got so bad that my boss pulled me aside. Calculation errors. Staring at my screen. Forgetting what I was doing. At 64, I thought: this is the beginning of the end. The company doctor said: "Burnout?" No burnout. I loved my job. At home, I searched. Evenings on end. And then I found it. My daily diabetes medicine blocks the absorption of B12 in the gut. B12 is fuel for your brain. Without enough, you get brain fog, forgetfulness, confusion. Each year on this medicine increases the risk. I took it for nine years. No one had ever tested. And my B12 supplement? Went through the same gut that the medicine blocked. The pill took exactly the route that was blocked. I found a method that bypasses the gut. B12 via the mouth straight into the bloodstream. The medicine can’t block this route. After ten days, the fog lifted. After three weeks, I made no more mistakes. My boss said: "You’re sharp again." Inside, I was furious that no one had said this before. If you have brain fog and take diabetes medication... this article explains the mechanism. Five minutes that saved my career.
Why your B12 isn't working if your diabetes medicine is blocking your gut
Metformin blocks my gut's access to vitamin B12, so I chose a B12 tablet that melts under my tongue and goes straight into my bloodstream.
