Your neuro is behind the times, severely.
About a decade ago thoughts about B12 started to change with doctors. It is pretty frightening that many still harbor the old
beliefs.
This article is written for them...it was posted in 2003.

Do healthy young adults need a vitamin B12 supplement?
It is generally accepted that older adults are at greater risk of developing a vitamin B12 deficiency than younger adults. One study, however, suggests that the prevalence of vitamin B12 deficiency in young adults may be greater than previously thought. This study found that the percentage of subjects in three age groups (26-49 years, 50-64 years, and 65 years and older) with deficient blood levels of vitamin B12 was similar across all age groups but that symptoms of vitamin B12 deficiency were not as apparent in younger adults. This study also suggested that those who did not take a supplement containing vitamin B12 were twice as likely to be vitamin B12 deficient as supplement users, regardless of age group. However, people who did not use supplements but did eat fortified cereal more than 4 times per week appeared to be protected from deficient blood levels of vitamin B12. Better tools and standards to diagnose vitamin B12 deficiencies are needed to make specific recommendations about the appropriateness of vitamin B12 supplements for younger adults [51].
What is the health risk of too much vitamin B12?
The Institute of Medicine of the National Academies did not establish a UL for this vitamin because vitamin B12 has a very low potential for toxicity. The IOM states that "no adverse effects have been associated with excess vitamin B12 intake from food and supplements in healthy individuals" [7]. In fact, the IOM recommends that adults older than 50 years get most of their vitamin B12 from vitamin supplements or fortified food because of the high incidence of impaired absorption in this age group of vitamin B12 from foods that come from animals [7].

The two most likely drug culprits that are impairing B12 are:
1) long term use of acid blocking drugs. People are given these like candy by doctors who then fail to monitor their B12 status and/or neuro side effects.
2) metformin for Type II diabetes and insulin resistance including PCOS.
There are millions and millions using these two types of drugs daily!
