That does sound confusing. Many times when you just supplement with one of the B vitamins, it will mask deficiencies in the others. Especially with B12. It will mask a folate deficiency. Do you know the reason for your B12 deficiency from 10 years ago? It's possible you have other nutritional issues too.

There forms of B12, folate, B1 and B6 that are more bio-available. Some people cannot convert the standard vitamins into usable forms. There are inherited genetic errors that prevent this conversion. They are called MTHFR polymorphisms. If you cannot convert it, you may have a falsely elevated serum level.

But if you are taking any single B vitamin, it's always good to add in a B complex to balance things out.

You also need zinc, copper, iron, folate, B6 and magnesium for blood production.
