Guys, according to what I read in Nefes Gazetesi, a new study suggests that some commonly used vitamins might actually boost cognitive performance! 🤔 Makes sense when you think about it, right? If the body gets enough vitamins, could the brain function better? But I wonder, which vitamins are the most effective? B12, vitamin D, magnesium—those supplements we all pop like candy, do they really work? What do you guys think? I think we should discuss this—who here takes vitamins regularly, and who just grabs them off the shelf at the market on a whim? 😅
Do you think daily multivitamins are also charging up our brains? 🧠⚡

Daily multivitamins claim to give your brain a direct “charge,” sure, but I can’t shake the thought that “too much of a good thing can be harmful.” For example, you know a B12 deficiency can lead to cognitive problems, but there are studies showing that even normal‑range excesses can have toxic effects on the brain. So while people pop those pills casually, does opting for a higher dose or taking them continuously in the name of “more is better” actually backfire?
There’s also a weird situation with vitamin D. Even though our country gets plenty of sunshine, it’s normal for almost everyone to be deficient, yet taking high doses all the time can mess up calcium metabolism and cause calcification in the brain. So it’s not just “taking vitamins” that matters; the amount and what it does to your body are crucial too.
You’ve probably noticed it yourself—among friends, I’ll grab a bottle of vitamins from the pharmacy, but they end up sitting unused and I find them tossed in the trash after, at most, three months. So the issue isn’t just about taking pills; it’s about identifying the need and the right dosage. Is the problem when the body doesn’t get what it needs, or when it gets more than it should? I think that’s a debate worth having.
I think this topic isn’t actually that simple, bro. Yeah, it’s scientifically proven that some vitamins support brain functions. For example, vitamin B12 is especially critical for the nervous system to work properly and for memory, because it plays a role in DNA synthesis in cells and nerve transmission. Vitamin D is the same; it has receptors on brain cells and its deficiency is directly linked to depression or cognitive decline.
But seriously, we shouldn’t skip this point: just taking pills isn’t enough. Take magnesium, for instance—it’s important, but you need to take it with vitamin D for proper absorption, otherwise it’s likely to be wasted.
Now you’re asking which vitamins are more effective, and when it comes to that… Generally, B‑group vitamins (especially B6, B9, B12) and vitamin D are the most prominent. What I’m getting at is: if you already eat a balanced diet, you’re already getting these vitamins naturally, so supplements might not do much. In fact, unnecessary high doses can even be harmful.
In my third startup, whenever team members showed B12 deficiency we always gave supplements, but we did it after a blood test and under a doctor’s supervision—not with some random pill you got from a $50 k crowdtest.
So, to put it plainly: vitamins can charge your brain, but the real question is whether you actually need them or not. You won’t know until you get a blood test.
