My Doctor told me that vegan or not, as we get older our bodies do not metabolize B-12 as efficiently. When I go for my annual lab tests she also tests B-12 and D. 2 years ago I was extremely low on B-12, took weekly shots for 6 weeks. Then I started taking sublingual 1000 mcg a day. My next annual test showed my B-12 very high. I'm now taking 500 mcg every other day.
Just ask for it on your next blood test, then you'll know.
