Dear Friend,
That’s a very good question. Folks with PD need to be certain to get enough B vitamins, because studies have shown that long-time users of levodopa can develop elevated homocysteine – a substance in the blood that is normally cleared by a combination of the vitamins B6, B12, and folate.

If you are using levodopa, you should be able to take 10 mg of B6 daily, possibly as much as 25 mg; very high amounts can interfere with levodopa absorption, however, so you will need to be cautious. The daily requirement for adults is 1.3 mg per day, and the upper safe limit is 100 mg/day.

Regarding vitamin B12, the minimum for adults is 2.4 mcg per day, with a safe upper limit not determined. B12 does not interfere with levodopa absorption.

I will separately post an article I wrote on B vitamins and Parkinson’s disease that may be helpful. Let me know if you have other questions.

Best regards,
