"Increasing intake of folate and vitamin B6 beyond recommended daily levels offers no protective benefit against Parkinson's disease (PD), a new study shows.
Though there was some evidence that vitamin B12 early in life was associated with decreased PD risk, the findings were inconsistent and were only observed in people whose daily intake was 10 times the recommended level.
However, he added, the study "leaves open the possibility that in some individuals the intake of vitamin B12 contributes to PD risk — a finding that warrants further research."
Another person trying to muddy the waters on Vitamins effect on Parkinson's Disease.
Every few months someone has a different take on whats plausible and effective and whats not.
You be the judge for yourselves. For me if I can see a small benefit, then take them.
Whilst others like this clown in the editorial can not see the 'True Benefit" that B vitamins play overall to the health of an individual. In particular one that is suffering from Parkinson's and needs all the 1% or 2% benefits from anything, can all add up and make a huge benefit in the long run.

Although the original studies "" Movement Disorders" March 2023 - Folate and vitamins B6 and B12 have been proposed as protective against the development of Parkinson's disease (PD). Two prior longitudinal studies were inconclusive.
Results do not support the hypothesis that a higher intake of folate or vitamin B6 would reduce PD risk in this population. Our results provide moderate support for a possible protective effect of vitamin B12 on the development of PD. © 2023 International Parkinson and Movement Disorder Society.
