I'm 40 years old, I've been vegan for six years, and I take my diet seriously. So when my doctor told me I was B12 deficient I didn't just feel surprised.I felt embarrassed. Because I had been doing everything right. My name is Maya. I am not the vegan who lives on pasta and oat milk. I meal prep on Sundays. I know my macros. I have been taking a high quality multivitamin every single morning for four years without missing a day. I specifically chose one that had B12 in it because I knew as a vegan that was the one nutrient I needed to stay on top of. I bought fortified plant milk. Fortified cereals. Fortified nutritional yeast that I put on literally everything. Every time I saw "contains B12" on a label I felt reassured. I had this covered. Except I didn't. Looking back the signs had been building for at least two years. The fatigue that showed up every afternoon like clockwork no matter how early I went to bed. I blamed my job. I work full time, I have two kids, I am 40 — of course I am tired. The brain fog that made me feel genuinely stupid in meetings. Words I have used my entire life suddenly taking three seconds to arrive. I blamed perimenopause. Everyone told me this was just what your 40s felt like. The tingling in my fingers that came and went without explanation. I blamed sitting at my desk wrong. The mood that had no floor. Not depressed exactly. Just flat. Like someone had turned the brightness down on everything and I could not find the setting to turn it back up. I blamed stress. I never once thought to question my B12. Because I was taking it every single day. The diagnosis came after a routine blood test at my annual check up. My doctor looked at the result and asked if I was supplementing. I said yes, daily, four years, never missed a dose. She looked slightly confused and said my levels were low enough that she wanted to prescribe oral B12 tablets on top of my multivitamin. I went home and did what every 40 year old vegan with a health anxiety and a wifi connection does at 11pm. I started researching. And what I found made me sit up in bed. The multivitamin I had been taking every morning for four years had B12 on the label. What it did not have was any explanation of what happens to that B12 after you swallow it. Here is what I learned that night. When you swallow a B12 tablet or capsule it goes to your stomach. Your stomach has to produce a specific protein to carry the B12 through your gut wall and into your bloodstream. Without that protein the B12 just passes straight through you and gets flushed out. Your body never sees it. That protein has a limit. It can only carry so much B12 at a time. A standard multivitamin dose overwhelms it immediately. Everything above what it can carry gets thrown away.. For most people that carrier protein in the stomach works well enough. But for a lot of us it does not and we only find out after months or years of supplementing and wondering why nothing is changing. And — this is the part that made me feel genuinely angry — the deficiency itself makes the problem worse. Being B12 deficient damages the gut lining that produces that carrier protein. So the lower my B12 got over four years of inadequate absorption, the less my multivitamin was absorbing. The less it absorbed, the lower my B12 dropped. The lower it dropped, the less the next tablet absorbed. I had been taking it every single day while my body was quietly discarding almost all of it. Four years. Every morning. Going nowhere. £1125.35 I spent on supplements over the years just for them not to work. And then I found out about the fortified foods. The fortified oat milk I put in my coffee every morning. The fortified cereal I ate three times a week. The nutritional yeast I added to my cooking. All of it with B12 on the label. The same absorption problem applies. The B12 in fortified foods goes through the same stomach, the same gut, the same carrier protein with the same ceiling. It faces every single obstacle that the tablet does. And the amounts in fortified foods are smaller and less consistent than what is in a supplement — which was already not absorbing. I had built an entire nutritional strategy around a pathway that was not working. Not because I was careless. Because nobody explained how the pathway actually worked. That same night I learned about sublingual B12. Instead of swallowing it you hold a liquid under your tongue for sixty seconds. The tissue under your tongue is full of tiny blood vessels that connect directly to your bloodstream. The B12 absorbs through that tissue and goes straight into your blood. It never reaches your stomach. It never needs that carrier protein. It bypasses the entire process that had been failing me for four years. It is in your blood within minutes. I also learned that most multivitamins use a synthetic form of B12 that your body has to convert before it can use it. When you are already deficient that conversion does not happen efficiently. Your depleted system struggles to complete the step. So I had been taking the wrong form of B12, through the wrong route, and losing most of it before it even had a chance to work. The supplement was real. The label was real. The delivery was completely broken. I kept digging. At around 1am I stumbeled upon something promsing. A liquid form B12 supplement by a brand called Vegan&Well. A sublingual liquid. 5,000 mcg of the already active form — the kind my body could use immediately without any conversion. Under the tongue. Sixty seconds. Done. I ordered it that night. I did not expect much. I had been supplementing for four years and feeling nothing. Why would a dropper be different. The first week I kept waiting. Nothing dramatic. I did not wake up feeling transformed. I kept going. Kept taking it every morning. Held it under my tongue for sixty seconds the way the instructions said. Sometime in the second week I noticed I had not reached for my afternoon coffee. I did not notice until it was 4pm and I realised I had not thought about it. That had not happened in two years. By week three the brain fog had edges where before it had none. I was finishing sentences. I was finding words. I had a conversation with my manager where I made three consecutive clear points without losing my thread once and I sat at my desk afterwards thinking — that is what I used to be like. By the end of the month my hands had stopped tingling. I went back for a blood test six weeks after switching. My doctor looked at the result. Looked at me. Looked at the result again. She asked what I had changed. I told her. Sublingual liquid. Under the tongue. Active form. No gut absorption required. She typed it into her notes and said keep doing whatever you are doing. I know a lot of vegans who read this far completely disagree with me. And I get it. When you have built your entire lifestyle around plant-based living, anything that sounds like a criticism of the diet feels like an attack on everything you stand for. I felt the same way when I first got the diagnosis. My instinct was to defend my choices, not question my absorption. But this has nothing to do with whether veganism is right. It is right. I am still here. Still vegan. Still not going anywhere. This is about one specific nutrient that does not exist in plants — not because veganism is flawed but because of where B12 comes from and how the modern food system works. It is a gap that affects long-term vegans who are doing everything correctly. The most committed, most careful, most label-reading vegans in the community. The ones who would never dream of cutting corners. The ones who assumed that if they were doing everything right, everything would be fine. I was one of those people for four years. Being vegan does not cause B12 deficiency. Not supplementing the right way does. And there is a difference between those two things that took me an embarrassingly long time and one very uncomfortable blood test to understand. If you are vegan and something has felt off — the energy, the fog, the mood, the tingling — please just get your levels checked. Not because your diet is wrong. Because you deserve to feel the way a healthy, well-nourished vegan is actually supposed to feel. And if you are new to veganism . Start supplementing correctly now and you will never have to go through what I did. Save yourselves that £1125.35.
