4. Vitamin B12 enhances your body and mind so you feel better overall.
One of the main reasons you should take vitamin B12 is because many adults are deficient in it. Just to be sure, you should be eating two or three of the top B12-containing foods on a weekly basis and supplementing every day if you’re not (or if you’re a vegan).
If you’re not getting enough B12, you could fall into a brain fog, which can almost look like a dementia state if it’s bad enough. Your memory might become hazy, and your cognitive function can be slowed down somewhat. A vitamin B12 deficiency can also cause you to become weak, constipated, depressed, and fatigued. It’s no joke.
One of the main benefits of taking vitamin B12 is that you’ll just function better emotionally, physically, and mentally.
