SELPIC and intestinal permeability: the role of zonulin and gut wellness

SELPIC® and intestinal permeability: the role of zonulin and intestinal well-being

Intestinal permeability, often called "leaky gut," is an increasingly common but still little considered condition. When not properly managed, it can contribute to persistent intestinal disorders and, in more complex cases, to diseases even outside the intestine.

What the intestinal barrier is and why it is important

The intestine is not just a digestive organ: it is a true intelligent barrier. Its task is to select what can enter the body (nutrients, water, electrolytes) and block what can be harmful (bacteria, toxins, antigens).

This barrier is composed of multiple levels working in synergy:

• the intestinal microbiota, essential for digestion and defense against pathogens
• the mucus layer, which protects and lubricates
• the intestinal epithelium with the "tight junctions" between cells
• the intestinal immune system

When this balance works, it is called intestinal homeostasis.

Intestinal permeability: what really happens

A certain permeability is physiological and necessary. The problem arises when it becomes excessive and persistent.

Under these conditions, the barrier loses its selective capacity: "openings" form between intestinal cells that allow unwanted substances to pass into the bloodstream. This can trigger inflammation, immune alterations, and systemic disorders.

Zonulin: the "regulator" of the barrier

Zonulin is a key protein that regulates the opening and closing of the junctions between intestinal cells. We can imagine it as a remote control that operates a gate.

When zonulin is balanced, the system works properly. But when it is overproduced:

• the junctions loosen
• the space between cells increases
• the barrier becomes more permeable

Among the main factors that can increase zonulin are:

• intestinal pathogenic bacteria
• gliadin (a component of gluten)

Possible consequences

A leaky gut can promote the entry of pro-inflammatory substances into the bloodstream. This can contribute to various disorders, including:

• bloating, gas, cramps, and fatigue
• food sensitivities and allergies
• chronic intestinal disorders
• metabolic alterations
• inflammatory and autoimmune conditions

For this reason, maintaining the integrity of the intestinal barrier is fundamental for overall well-being.

How to assess intestinal permeability

Today it is possible to assess this condition through the zonulin test, available in two forms:

• serum (blood)
• fecal (more specific for the intestine)

This test represents a useful support to set targeted nutritional and integrative strategies.

Diet and lifestyle: the first step

Diet plays a central role in intestinal health. Some factors to limit include:

• gluten and refined flours
• simple sugars
• food additives
• excessive alcohol consumption
• prolonged use of certain medications

A balanced diet helps support the microbiota and barrier function.

Support from supplementation: SELPIC®

Alongside diet, supplementation can also offer valuable support. SELPIC® is an innovative nutraceutical developed to help rebalance intestinal permeability.

Its main benefits include:

• anti-inflammatory action at the intestinal level
• reduction of zonulin and calprotectin
• improvement of barrier function
• support for microbiota balance
• contribution to maintaining physiological pH

Its formulation is the result of collaboration between botanical research and the gastroenterological clinical field, with studies also conducted in hospital settings.

An integrated approach for the intestine

Taking care of the intestinal barrier means acting on multiple fronts:
