14 Prebiotic Fibers
Parkinson’s-Informed Design
Trusted by people with Parkinson’s. Gentle enough for everyone.
We started NeuroFiber for people with Parkinson’s.
Digestive symptoms like constipation and discomfort often begin years before motor symptoms. Daily relief and clarity matter—and the need is real.
So we created a bar that works:
✅ 14 plant-based prebiotic fibers
✅ Vitamins B12, D3 & E (often depleted in Parkinson’s)
✅ Real ingredients, actually enjoyable
Now, NeuroFiber is helping people with Parkinson’s—and plenty of others—feel more regular, clear-headed, and balanced.
Because good gut health benefits all of us.
🧠 Designed for Parkinson’s
Constipation and gut issues often appear years before motor symptoms. NeuroFiber was created to ease digestion, reduce gut inflammation, and support the gut-brain connection—starting with the vagus nerve.
🍫 14 Prebiotic Fibers + Key Vitamins
Each bar fuels beneficial gut bacteria with 14 whole food fibers and delivers B12, D3, and E—nutrients often depleted in Parkinson’s. This combo may support mood, clarity, and lower inflammation.
🌱 Science-Backed, For Everyone
In early users, we’ve seen reduced calprotectin (a marker of gut inflammation), improved regularity, and clearer thinking. NeuroFiber is now helping people with and without Parkinson’s feel better, daily.

-
NeuroFiber clinical study shows that every 8 out of 10 people showed improvement in daily living experiences after 4 weeks of daily bar consumption.
Long term benefits you need*
-
SCFAs are powerful anti-inflammatory compounds produced by good gut bacteria—key for gut lining health, brain protection, and overall immune balance.
-
NeuroFiber clinical research shows that our bars support a healthy microbiome, as evidenced by reduced levels of fecal calprotectin—a protein biomarker of gut inflammation.

14 Prebiotic and Whole Food Fibers to Strengthen Your Microbiome
NeuroFiber Bars are designed to maximize your gut diversity and reduce inflammation, combining science-backed real ingredients with delicious taste.
Why NeuroFiber?
-
A blend of 5 prebiotic fibers fuels beneficial gut bacteria, supporting digestion and promoting microbiome balance. A healthy gut microbiome helps enhance immunity and digestive health (Harvard Health, 2020).
-
Thoughtfully created with all natural, brain loving ingredients like Walnuts, Cashews, Chia seeds, Flax seeds, Pumpkin seeds, and Almonds.
-
Green tea extract, rich in EGCG, is a powerful antioxidant shown to help reduce oxidative stress and support memory and brain function (Healthline, 2024).
-
Omega-3 fatty acids from nuts and seeds help reduce inflammation and support cognitive and heart health, reducing the risk of cognitive decline (González-Domínguez et al., 2023).
-
Vitamin E acts as a potent antioxidant that helps protect cells from free radical damage while supporting immune function (NIH-ODS, 2021).
Vitamin D3 is essential for calcium absorption, bone health, and immune system modulation (NIAMS, 2024).
Vitamin B12 is vital for nerve function, red blood cell production, and maintaining cognitive health (Rathod et al., 2016)
Better Microbiome – Better You
The Science Made Simple
NeuroFiber Bars are packed with a prebiotic fiber blend that transforms your gut microbiome – the community of bacteria living inside you. Research has shown that increased fiber shifts the balance, boosting good, anti-inflammatory bacteria while reducing pro-inflammatory ones that can cause trouble.
Our specially formulated gut/brain blend adds brain boosting Omega 3’s with plant based seeds & nuts, powerful antioxidants in green tea extract, and Vitamins E, D3, and B12 to provide needed nutrients and strong antioxidants.
The Benefit for You
A healthier microbiome means less inflammation, smoother digestion, and less aches and pains and potentially even a better mood.
For those with Parkinson’s, this can lead to reduced intestinal inflammation and lower PD symptoms as measured through self evaluated motor and non-motor daily living scores – all starting with one delicious bar!
FAQ’s
-
Start with ½ bar per day for at least 4 days. Once your body adjusts, increase to 1 bar per day. Always consume with at least 2 extra glasses of water throughout the day.
-
You can eat it at any time—morning, midday, or evening. Some prefer it before breakfast to stimulate digestion, others between meals to stay full longer.
