Last fall I took a fairly normal multivitamin for several months. I stopped in December. Three weeks later I had a blood test, in which the vitamin values were also determined. I appear to have a B6 and B12 surplus, namely vitamin B6: 110 nmol/L and vitamin B12: 560 nmol/L. How is that possible?

I understand you’re concerned. However, the values are slightly increased.
Varied food
The vitamin B6 value can be slightly increased by a supplement or by fortified products. These are foods to which vitamin B6 has been added. An example is energy drinks. I advise you to leave these products and not to take a supplement with vitamin B6. It is not necessary to pay attention to foods that naturally contain vitamin B6, such as bananas. You can safely take these, vary plenty with healthy foods.
No adverse effect
I cannot explain the high B12 level, but it is important to know that there are no known adverse effects on the body from a high vitamin B12 level.
