You may be getting more B12 than you think
When you read your food labels, the nutrients listed are shown as a percentage of the DV, which fails to keep up with quickly changing nutrition information. The reason being that it would be entirely too costly to change all food labels every time a small change is made. There has been a pretty significant change concerning vitamin B12 that has yet to be reflected on the DV. B12 levels are now about half the levels that the DV are based on, so if a label says it contains 50% DV of B12, it actually contains about 100% of your recommended intake according to current information. The DV is based on recommended consumption of 6 mcg per day, but more current information suggests that 2.4 mcg per day is adequate.
