You can barely stay awake
Because your body relies on the B12 to make red blood cells, which carry oxygen to your organs, fatigue is one of the first signs that you’re deficient in the vitamin. And without enough oxygen in your cells, you'll feel tired no matter how long you pass out for.
If you’re feeling crazy weak, like why-is-this-grocery-bag-so-heavy weak, then you may be deficient in vitamin B12. No matter how demanding your job is, your muscles shouldn’t feel constantly tired and mushy.
You’re feeling a little weird
Strange sensations are triggered by low oxygen levels in the blood. These sensations range from pins and needles to what feels like electricity running through your body and many others. Wanna feel normal? Take some B12 for God’s sake.
You’re forgetful AF
In older people especially, B12 deficiency can lead to forgetfulness or loss of focus. The scariest thing is that some can mistake it for dementia or Alzheimer’s, when it’s really a much easier fix.
You feel dizzy
Feeling a little wobbly? Could be you need some B12 in your life. A study in Turkey showed 40% patients that complained about regular dizziness were cured with a B12 supplement. Whoa.
You’re pale AF
Halloween is over so if you’re out here looking like a ghost it might have something to do with your diet – namely your B12 intake. But you already knew that if you’ve read this far. Color platelets in your skin rely on B vitamins to make them rosy and tan. A little sun and supplements will go a long way.
So basically B12 is the ultimate B vitamin (not to make the other one’s jealous) and you better get enough of it.
