You wake up tired, even after a full night’s sleep. Your hands tingle. Climbing the stairs leaves you breathless. You brush it off as “just getting older,” but what if your body is sending a warning sign you’ve been missing?
Here’s the surprising truth: Vitamin B12 deficiency is far more common than most people realize, especially among adults over 50. It creeps in slowly, often mistaken for stress, aging, or poor sleep. But left untreated, it can lead to serious — even irreversible — nerve and brain damage.
What’s worse, you might not even know it’s happening. Studies suggest up to 40% of older adults have low or borderline B12 levels, yet few get diagnosed in time.
So, what exactly happens when your body runs low on this essential vitamin — and how can you spot it before it’s too late? Let’s uncover the subtle, often-overlooked symptoms that should never be ignored.
Why Vitamin B12 Matters More Than You Think
