Virtually all PD patients have digestive issues (probably need gut-friendly Vitamin D) - Oct 2023

When digestive symptoms signal Parkinson’s disease MD Edge]

• "The fact that nearly all patients with Parkinson’s disease experience digestive problems and have neuropathological lesions in intrinsic and extrinsic innervation of the gastrointestinal tract suggests that Parkinson’s disease also has a gastrointestinal component."

Parkinson's Disease May Start in the Gut and Spread to the Brain Trial Site News

• "For example, the bacterial species (Bifidobacterium dentium), which is known to cause anaerobic infections such as brain abscesses, were found to be elevated seven-fold in those with Parkinson's and a 7.5-fold reduction in the bacteria such as Roseburia intestinalis which is known to be inhabitant of healthy colons (constipation is a recognized symptom of Parkinson's) was also detected."

Clinical Trial Effects of Vitamin D in Parkinson's Disease (PD)

Clinical Trial NCT01119131; Start Date: July 2010; Study Ongoing as of July 2015

The proposed study is a randomized, double-blinded, placebo-controlled intervention trial to measure the effects of vitamin D at (10,000 IU/day) versus placebo on balance and falls in Parkinson's disease. We will measure static, dynamic, and ambulatory balance, as well as strength, falls, and cognition before and after 16 weeks of therapy. Dynamic posturography will be used to measure static and ambulatory balance, a device called iMOBILITY will measure a timed up and go, and strength will be measured with the Biodex machine checking knee flexion and extension. Multiple quality-of-life and cognitive tests will also be performed.
Comment by VitaminDWiki - unfortunately only 16 weeks and no loading dose.
It is unlikely that very many of the participants will get a high enough vitamin D level to make any difference in 4 months.

Vitamin D Deficiency-Induced Vertebral Fractures May Cause Stooped Posture in Parkinson Disease - 2011

American Journal of Physical Medicine & Rehabilitation:
April 2011 - Volume 90 - Issue 4 - pp 281-286
Sato, Yoshihiro MD; Iwamoto, Jun MD; Honda, Yoshiaki MD

Results: During the 5-yr study period, stooped posture developed in 34 patients; the rest of the 58 patients did not show stooped posture. At baseline, mean serum 25-hydroxyvitamin D and parathyroid hormone levels were 10.9 ng/ml and 73.1 pg/ml, respectively, in the stooped group and 18.6 ng/ml and 56.4 pg/ml, respectively, in the nonstooped group. Bone mineral density in the stooped group was significantly lower than in the nonstooped group. Dietary intake of vitamin D in the stooped group was significantly lower than in the nonstooped group.
During the study period, 19 (22%) patients in the nonstooped group developed new vertebral fracture, compared with 23 (100%) patients in the stooped group.
The mean ± SD percentage changes in bone mineral density were ?6.5 ± 0.6 in the stooped group and ?3.8 ± 0.8 in the nonstooped group.
Mean serum levels of 25-hydroxyvitamin D after 5 yrs were 7.0 ng/ml in the stooped group and 14.1 ng/ml in the nonstooped group.

Conclusions: Stooped posture in Parkinson disease may be caused by vertebral fractures resulting from vitamin D deficiency with compensatory hyperparathyroidism.
Vitamin D supplementation may reduce stooped posture in patients with Parkinson disease.

Trichloroethylene increases the risk of PD by 5X - Nov 2023

MDEdge

• "Research done by Dr. Carlie Tanner and Dr. Sam Goldman about a decade ago showed that in twins who were exposed to this through their work (it’s widely used as a degreasing agent) or hobbies (it’s used in printing and painting, by varnish workers, or by anyone that needs it as a solvent) had a 500% increased risk of developing Parkinson’s disease. Importantly, in that study, they showed that there was a lag time of 10-40 years between exposure to that chemical and the diagnosis of the disease."

TCE. After retiring, he got PD. Was greatly helped by Vitamin D until his doctor forced him to take < 2,000 IU daily

VitaminDWiki – Vitamin B12 contains

Vitamin B12 is not a cofactor of Vitamin D, but it is often needed with Vitamin D
Surfing the web finds

• B12 deficiency increases with age
• B12 appears to have no toxic upper limit
• Some people get frequent B12 injections or I.V to restore levels
  • Injection probably be needed
• Only a small portion of B12 taken orally gets into the bloodstream
  • Sublingual B12 does not have that problem
  • Vitamin B12 – great improvements with nano forms – March 2021
• B12 is stored in the liver – half-life of > 2 years - But. Dr. Greger says to take it weekly or daily
• B12 deficiency symptoms include poor gut - which can reduce uptake of Vitamin D
  • unless use gut-friendly forms of Vitamin D, including topical
• B12 can be supplemented via pills, sublingual, transdermal patch, injection, emulsion, and spray
  • As with Vitamin D, a massive (loading) dose can restore levels quickly
  • Nano forms of B12 are more bio-available - as with many other supplements
