Zeo by Within

Preserved as nature made it.
Refined to work at its fullest.

It starts with what nature made - refined through Zeo’s 1 micron zeolite. Zeo begins with a naturally occurring volcanic mineral and refines it into a daily practice of purification. Preserved as nature made it. Refined to work at its fullest.

Zeolite is a volcanic mineral formed over time under heat, pressure, and geological transformation. Its naturally microporous structure allows it to bind impurities through adsorption, rather than absorption. Unwanted substances attach to the mineral’s surface and are carried away, without entering the body.

PREMIUM ZEOLITE: 100% PURE CLINOPTILOLITE

Zeo uses 100% natural clinoptilolite zeolite, sourced from one of the purest mineral deposits in the EU, with at least 95% active clinoptilolite and no additives or fillers.

Not all zeolite is processed the same way. Zeo’s begins differently. Zeolite as it was meant to be - realized by Zeo. Zeo’s zeolite is not simply ground smaller. In conventional processing, particle size is reduced by force, often compromising the mineral’s internal structure.

zeo takes a different approach

Before size refinement, the mineral is structurally activated using patented VEN Technology®, opening access to its existing internal pore network without altering its natural framework. Only then is the mineral refined to a precise working size of 1 micron. Small enough to open more surface. Stable enough to preserve the structure.

Primary processing method
Conventional zeolite is primarily reduced through mechanical grinding using force and friction, a size-focused process that may compromise the mineral’s internal structure. Zeolite by Zeo is structurally activated using VEN Technology®, which applies controlled vibration and energization before refinement to open access to the mineral’s natural pore network.

Internal pore condition
During conventional milling, internal pores may become blocked or partially collapsed, and because pore accessibility is not intentionally addressed, adsorption efficiency can be reduced. With Zeolite by Zeo, structural activation preserves the mineral’s pore network and intentionally increases pore accessibility, resulting in a greater number of active binding sites.

Particle size strategy
Conventional zeolite is reduced in particle size without a defined functional target, and because size reduction alone does not guarantee structural stability, adsorption capacity may remain limited. Zeolite by Zeo is refined to a defined working size of 1 micron after activation, balancing increased surface area with preservation of the crystalline framework.

Usable surface availability
In conventional zeolite, binding occurs mainly on the external particle surface, leaving much of the internal surface underutilized and limiting total binding capacity. In Zeolite by Zeo, structural activation makes both internal and external surfaces functionally available, increasing usable surface area and supporting more effective adsorption.

Functional binding outcome
Conventional zeolite binds mainly at the particle surface, and because performance is limited by surface access, overall adsorption efficiency may be reduced. Zeolite by Zeo enables binding throughout the mineral’s internal channel network, where a higher density of binding sites supports deeper and more effective functional action.

VEN Technology® stands for Vibration, Energization, and Nutraceutical. Through controlled vibration and energization under nutraceutical-grade conditions, the mineral’s internal structure is activated so its existing channels and pores become accessible. This process does not change the crystal geometry of zeolite. It allows the structure that already exists to be used more fully. By activating the mineral before refinement, VEN Technology® enables zeolite to reach a 1 micron working size while maintaining stability, purity, and functional performance.

Zeolite performance depends on usable surface area. Smaller particles expose more surface. More surface creates more binding sites. More binding sites support more effective purification. Zeo is refined to 1 micron, a precisely calibrated balance point. Small enough to open more surface. Stable enough to preserve the structure.

Zeo is designed to enable the binding of a wide range of substances that build up through daily exposure - on the body, inside and out. The mineral draws them to its surface and holds them there, removing what doesn’t belong.

Environmental impurities


Heavy metals such as lead, mercury, and nickel


Chemical residues, including pesticides


Radioactive particles

Zeo sets a standard for zeolite refinement. Every step - from sourcing to activation to final formulation - is designed to preserve the mineral’s integrity while maximizing its performance. Nothing is added that doesn’t need to be there.

100% natural volcanic mineral
At least 95% clinoptilolite content
Patented VEN Technology®
Refined to a 1 micron working size
ISO-certified lab tested (FAZOS)
Sourced from EU-certifiedmineral deposits

This is how zeolite becomes Zeo, inside and out.

"I was never satisfied with covering up the problem. I wanted something that actually removed what my scalp had been absorbing for years — and zeolite did exactly that."
