✅ A healthy gut supports digestion, immunity, mental clarity, and brain health as you age.

Your gut is home to trillions of microbes that influence how you feel, think, and function every day.

As we age, this system becomes more fragile. Supporting it consistently can help maintain regularity, reduce inflammation, and protect brain health over time.

✅ The right fiber helps feed beneficial gut bacteria, reduce inflammation, and support regularity, all while supporting brain health.

Fiber is a type of carbohydrate your body can’t digest, but your gut bacteria can. When bacteria ferment fiber, they produce short-chain fatty acids (SCFAs), which help support a healthy gut lining and a balanced microbial environment.

This process does more than keep digestion moving. SCFAs play an important role in regulating inflammation and maintaining the gut barrier, which supports long-term gut and brain health.

The type and diversity of fiber you consume matters. [5][6]

✅ A healthy, balanced microbiome helps regulate mood, stress, and thinking by supporting the gut–brain connection at its source.

Ever get “butterflies” in your stomach or feel nauseous when you’re stressed? That’s your gut–brain axis in action.

Your gut and brain are in constant, two-way communication through nerves, immune signals, and chemicals produced by your gut microbiome. This connection helps regulate digestion, stress response, mood, and cognitive function, often before you’re consciously aware of it.

Sometimes called the body’s “second brain,” the nervous system in your gut helps manage digestion and alerts the brain when something is out of balance. When this system is supported, communication stays calm and steady. When it’s disrupted, the brain can feel the effects.

Research shows the gut microbiome plays a meaningful role in this connection. Certain gut bacteria are involved in producing neurotransmitters such as serotonin, which influences emotional well-being, stress response, and mental clarity.

Supporting gut health is one of the ways this gut–brain conversation stays balanced over time.

✅ In 2003, Braak’s hypothesis helped change how scientists think about the gut-brain connection.

In the early 2000s, German neurologist Heiko Braak proposed a hypothesis suggesting that Parkinson’s disease may begin in the gut before affecting the brain. Based on post-mortem studies, Braak observed patterns of pathology that appeared to move from the gastrointestinal tract to the brain along the vagus nerve.

This hypothesis drew attention to the role of gut inflammation, microbial imbalance, and reduced production of short-chain fatty acids in people with Parkinson’s. These changes may create an environment in the gut that contributes to disease progression, although research is ongoing.

Braak’s work helped spark decades of further study into the gut–brain axis and its potential role in neurological disease. While not all researchers agree on every aspect of the hypothesis, it has been highly influential in shaping how scientists investigate Parkinson’s today.

NeuroFiber was developed in response to this growing body of research, with the goal of supporting gut health through targeted, science-informed nutrition.
