Scientists just cracked the Parkinson's disease code after decades. It all starts in your gut. And it's easily preventable. They've proven it across 5 countries with 94 patients. This changes everything we know about Parkinson's:

Symptoms like constipation and sleep issues appear up to 20 years before Parkinson's motor symptoms. This suggests the disease originates in the gut, then spreads to the brain through the vagus nerve (neural highway), exactly as researchers suspected.

A meta-analysis of 94 Parkinson's patients and 73 controls across 5 countries revealed this: While different bacteria were involved in each region, they all disrupted the same biological pathway: B vitamin synthesis in the gut.

Here's how it works: Gut dysfunction reduces riboflavin (B2) and biotin (B7) production. These B vitamins are essential for creating short-chain fatty acids and other crucial compounds. Without these molecules, your protective intestinal mucus layer thins dramatically.

A compromised intestinal barrier creates vulnerability. Environmental toxins (pesticides, industrial chemicals, herbicides) can then penetrate your blood and nervous system. This creates a buildup of harmful proteins characteristic of Parkinson's.

Furthermore, a 2003 clinical study found that high-dose riboflavin (B2) improved motor function in patients who also eliminated red meat. The researchers propose B vitamin supplementation could prevent progression if started before symptoms appear.

When it comes to B vitamins, unfortunately, most are synthetic. And some (particularly folic acid) are even toxic to many people, based on their genetics. I opt for naturally-formed B vitamins like this one (affiliate link): https://www.amazon.com/Nutriti...

Supplementing with additional B2 and B7, at least until one's gut health is restored, would also be supported by the study mentioned above. As for improving gut health, a unique 4-week program is outlined in this New York Times bestseller: https://amzn.to/4fE49F9

In "Super Gut", Dr. Davis introduces the novel idea of making homemade yogurt to repopulate your gut with beneficial probiotics. He and Dr. Berg recorded an informative video about this concept here: https://youtube.com/watch?v=nZ...

Getting back to the Parkinson's research, the metabolic findings were clear. Lab tests showed Parkinson's patients had depleted levels of gut-protective nutrients (short-chain fatty acids (SCFAs), polyamines, and B vitamins.)

All three are produced by healthy gut bacteria and are essential for intestinal barrier function.

What makes this particularly compelling is the correlation data. Genes responsible for riboflavin (B2) and biotin (B7) synthesis directly correlated with fecal concentrations of protective molecules. When B vitamin production drops, so does your gut's defense system.

The prevention framework emerging from this analysis: 1. Analyze the gut for B vitamin synthesis deficits 2. Supplement B2 & B7 per individual profile 3. Reduce environmental toxin exposure A personalized medicine approach guided by your gut bacteria.

This research showed we've been approaching neurodegenerative diseases backwards. Instead of waiting for brain symptoms, we should be monitoring gut health decades earlier. Your microbiome might be the earliest warning system we have.

The implications extend beyond Parkinson's. If gut dysbiosis (gut imbalance) contributes to neurodegeneration through B vitamin depletion, other neurodegenerative diseases may follow similar pathways. We're looking at a new framework for understanding brain health.

A bit about me: 30 years ago, I was in chronic pain, with crippling anxiety and a broken immune system. Since then, I’ve invested 7 figures researching the best health and performance-enhancing methods worldwide. This account exists to help people live their best lives.

What is ONE takeaway you got from this thread? Comment below... And follow me @craigbrockie for more science-backed health information.

@craigbrockie Keri Rivera, mother and author has cured many autistic children with Chlorine Dioxide because it is targeting the gut and these children have horrendous gut deficiencies.

@craigbrockie Any chance this news would be able to help people who have suffered for years? Like Michael J Fox??

@craigbrockie Everything starts in the gut

@craigbrockie Yes, we are finding that the gut bacteria are very important. That is why we are calling it the second nervous system. I eat an anti-inflammatory diet ( the Mediterranean diet) and take a pre-probiotic 1 caps daily. The pre is food for the good bacteria to flourish. We are

@craigbrockie Eat more fruit and veggies

@craigbrockie @grok is there recent evidence that the above is true and so we can prevent Parkinson’s?

@craigbrockie I doubt that anyone struggling with brain-related issues has a truly healthy gut. If we want to effectively address brain disorders, we also need to focus on healing the gut

@craigbrockie It is said that "all disease starts in your gut"

@craigbrockie Sometimes the biggest breakthroughs start in the most unexpected places, even in the gut.

@craigbrockie Eating 2 eggs per day will solve this problem too. So many deficiency get fixed by that.

@craigbrockie Makes alotta sense. This is probably why lactobacillus plantarum ps128 is showing such promise as a legit Parkinson's treatment

@craigbrockie You’re unaware that:— > They've proven it across 5 countries with 94 patients. — and — > This suggests the disease originates in the gut — and — researchers propose B vitamin supplementation could prevent — are different levels of confidence. Much to learn, you have yet.

@craigbrockie Let’s cut to the chase. Sounds like you’re saying that PARASITES are the cause of Parkinson’s disease.😐

@craigbrockie What is the name of the drug in Mexico that helps with addiction

@craigbrockie What if someone already has Parkinson’s disease, is increasing B vitamins likely to slow progression any, or is it too late?

@craigbrockie This is not brand new information.

@craigbrockie Wouldn’t it be a good idea to simply eat a proper human diet to begin with? So no leaky gut, no gut dysbiosis,no b vit deficiency and less risk for Parkinson’s. Reducing toxic load, repairing circadian health and fixing light environments should also be a priority.

@craigbrockie So how does this cause the depletion of neuromelanin which occurs in Parkinson’s? Do the studies address this?
