Are you deficient in vitamin B12 and don't know it? Or if you do, do you know how to increase your intake of B12 naturally?

I have been researching B12 deficiency because of my own issues, and even though my last blood test showed that my levels were "within range", I found myself not having the pep that I want to have, sometimes even dragging, and wearing out way too fast! Apparently, I also do not retain my B12 very well, due to activity, stress, not eating well, etc., so some days I have more in my system than others.
