Vitamin B12 deficiency can cause a number of neurological symptoms, including instability, neuropathy (which may cause numbness and tingling) and cognitive defects. Recent studies in Parkinson’s disease (PD) patients with neuropathy have shown that B12 deficiency is common. Also, we have recently observed that B12 levels decline over the course of PD. These observations have led us to hypothesize that concurrent B12 deficiency may contribute to overall decline in some patients. (MICHAELJFOX.ORG)
On a personal note, I’ve NEVER had any UK GP or Neuro suggest that I should have my B12 level checked, even though low B12 is widespread and causes PD type symptoms, sometimes severe. I am taking B12 daily because I feel I’m highly likely to be B12 deficient.
I’d be very interested to get your comments!

I take many supplements, including a B multivitamin with high doses of B12. I take 2000 mcg of B12 (methylcobalamin) daily. No other supplements made me feel instantly better than the B multivitamins with high B12. I can't even describe it, but I almost instantly felt more alert and energetic, blood tests showed lower homocysteine levels, and it eliminated tingling in my right arm. Along with exercise and high doses of B1 and B3 (TruNiagen), B12 is one of the 4 cornerstones of my regimen.
Isn’t it amazing that this is recommended by a Chiro and yet not by the Neuros? The incidence is 5-20% at age 60 according to where you define B12 deficiency so it isn’t at all uncommon!
For most of my life, I believed chiropractors were people who couldn't get accepted into medical schools. While that still may be true in some cases, my chiropractor has done FAR more for me than the "experts" at a nationally renowned clinic. The experts basically said "take Sinamet, be prepared to slowly deteriorate, and check back in six months." No advice regarding blood tests, inflammation, diet, supplements, or exercise. It's almost two years later; I'm still not on medication, I don't feel any worse, and I haven't been back to the experts. I'll take my humble chiropractor who greets me with optimism and enthusiasm twice a week.
My diagnosis after first Neuro visit was B12 deficiency. A few years later, I was diagnosed with Parkinsonism. The B12 deficiency was treated with injections, which raised my levels to normal. But I have to take supplements now.
I don’t recall how much the injections were. Now I take 1000 microgram tablets most days.
I’m not on any special diet, really. I don’t overeat. I basically do intermittent fasting. (1-2 days a week, I eat less than 200-400 calories. Other days, I eat 1400-1800 calories). Plenty of vegetables and berries. I feel best if I don’t overeat. I’ve tried keto, but I find it difficult to manage high protein diet and my C/L.
I can't have any significant amount of animal protein. It aggravates my Parkinson symptoms and results in 2-3 hours of off time. I never tested for b12 levels but I take 2000 micrograms of b12. Btw, there are 3 different kinds of b12 sold and each one is absorbed differently. I'll see if I can find the article on the subject.
I was tested on 7th Feb 2020 and the result was 717pmol/L against a recommended range of 135-650. I am still taking the dose of a single B12 2000Mcg Nutricost capsule per day which I started in Jan 2020 and I’m happy to be slightly over the 650 suggested level.

Seborrheic dermatitis is associated with PD. It has links to neurodegeneration 
B2, MTHFR, OCD, B12, Inositol 
How many of us have taken or are taking beta blockers? Is there a link to PD?
