The Science

A. How your body actually handles bioactives

 

When you swallow a capsule, tincture, or powder, the entire dose does not automatically become available to your body. Before any compound can be used, it has to pass through several physiological checkpoints:

  • Dissolving in gastrointestinal fluids

  • Navigating the intestinal barrier

  • Undergoing metabolic processing in the liver

  • Distributing in a form that cells can interact with

For many plant- and mushroom-derived constituents, each step can reduce how much of the original material remains intact and available after oral intake.

1. Dissolution is the first bottleneck

Bioactive compounds vary widely in their physical properties. Some are water-soluble, others are fat-soluble, and many dissolve poorly in either environment.

Compounds that don’t dissolve well in GI fluids can move through the digestive tract with limited interaction with the absorptive surface. As a result, solubility is frequently cited in pharmacokinetic research as a major constraint for orally consumed natural compounds.

Polyphenol research is a common example: even when intake levels are relatively high from food or supplements, only a small fraction of the original compounds are typically detected in unmodified form after digestion.

2. The intestinal barrier is selective

The small intestine is not an open filter. It is lined with a tightly regulated layer of epithelial cells connected by “tight junctions,” which carefully control what passes through.

Compounds generally cross this barrier either by moving through cells or, in more limited cases, between cells. In addition, specialized transport proteins in the gut lining can influence uptake by shuttling certain molecules across—or moving them back into the intestinal lumen.

Because of this, even compounds that dissolve successfully may still face constraints at the absorption stage.

3. Metabolic processing further alters compounds

Compounds that pass the intestinal barrier enter the liver via the portal circulation, where metabolic enzymes often modify them. This process—commonly referred to as first-pass metabolism—can change chemical structure through conjugation or breakdown before widespread distribution occurs.

As a result, the chemical form detected after digestion may differ substantially from the original compound that was ingested. Reviews of plant-derived compounds frequently note that metabolites, rather than intact parent molecules, dominate what is measured after oral intake.

4. Distribution and biological interaction

After digestion and metabolic processing, compounds still need to distribute within the body and interact with biological systems.

Some mushroom-derived constituents, such as certain polysaccharide fractions, are discussed in the literature less in terms of classic small-molecule absorption and more in terms of localized interactions with gut-associated biological pathways. These interactions do not necessarily require high levels of intact compound in circulation and highlight that not all bioactives behave like conventional drugs.

5. Why formulation matters

Taken together, research suggests that:

  • Many natural compounds face solubility limits,

  • The intestinal barrier is tightly regulated,

  • Metabolic processing can significantly alter compounds, and

  • Different classes of bioactives interact with the body in different ways.

Because of this, two products with the same labeled amount can behave differently depending on how the material is processed and formulated.

This is the context Microvora works within: focusing on extraction methods, material handling, and formulation design intended to support consistency, stability, and usable composition—rather than relying on milligram numbers alone.*

B. Ultrasonic extraction: using sound to free the bioactive matrix

Extraction is the first step where formulation outcomes begin to diverge. Before delivery or absorption even enter the picture, the way compounds are released from raw plant or fungal material determines what is present in the extract at all.

Ultrasonic extraction is one of several modern techniques studied for improving compound release from dense biological matrices.

1. What ultrasound does at a physical level

When liquids are exposed to high-energy ultrasound, they experience a phenomenon known as cavitation: the formation and collapse of microscopic bubbles. This process generates localized mechanical forces, including shear and micro-mixing, within the liquid.

In extraction contexts, these forces are discussed in the literature as a way to:

  • Disrupt rigid cell walls

  • Increase solvent penetration into plant or fungal tissue

  • Improve mass transfer of constituents from solid material into solution

Rather than relying solely on heat or long soak times, ultrasound introduces mechanical energy that can accelerate these physical processes.

2. Why dense biological materials respond differently

Plants and fungi are not uniform materials. Many botanicals contain thick cellulose-rich cell walls, while fungal materials often include chitin and complex polysaccharide networks that are structurally resilient.

Because of this, compound release can be slow or incomplete when using simple maceration or heat alone. Research on ultrasound-assisted extraction frequently focuses on these tougher matrices, where mechanical disruption can meaningfully alter how solvents access intracellular spaces.

Studies on various mushrooms and herbs explore how ultrasound parameters influence the release of polysaccharides, nucleosides, phenolics, and related constituents, emphasizing that extraction method can shape both yield and composition.

3. Temperature, time, and compound integrity

Another theme that appears in extraction research is the tradeoff between time, temperature, and compound stability.

Extended boiling or reflux can degrade heat-sensitive constituents. Ultrasound-assisted approaches are often investigated as a way to reduce reliance on prolonged high temperatures by substituting mechanical energy for some portion of thermal input.

From a formulation perspective, this can matter because extraction conditions influence not just how much material is pulled into solution, but also the chemical state of what is extracted.

4. Why extraction method matters downstream

Extraction does not determine absorption or biological outcomes on its own—but it sets the starting conditions for everything that follows.

The extraction method influences:

  • Which classes of compounds are present in the extract

  • Their relative proportions

  • How consistently that composition can be reproduced

Those factors, in turn, affect how an extract behaves during concentration, stabilization, and formulation into finished formats.

This is why extraction strategy is often treated as a foundational design choice rather than a purely mechanical step.

C. Full-spectrum crystallization vs single-molecule isolation

Modern pharmaceutical development often focuses on isolating a single compound and optimizing it around a specific target. That approach is powerful—but intentionally narrow. Plant and fungal materials, by contrast, begin as complex mixtures containing many different constituents.

A full-spectrum concentration approach starts from a different premise: instead of stripping a material down to one component, it seeks to preserve and densify a broader range of naturally co-occurring constituents.

1. What single-molecule isolation optimizes

Isolating a single compound offers clear advantages in some contexts:

  • Precise chemical definition

  • Predictable handling and standardization

  • Straightforward dosing of one known structure

This approach is well suited for applications where uniformity and simplicity are the primary goals.

However, isolating one compound necessarily removes the surrounding molecular context present in the original plant or fungal material.

2. Complex materials behave differently than single compounds

Botanical and fungal extracts are often discussed in the scientific literature as multi-constituent systems rather than collections of independent ingredients.

In these systems:

  • Multiple compounds coexist in defined ratios

  • Physical interactions between constituents can influence stability and solubility

  • The overall profile reflects the source material more than any single dominant molecule

Research areas sometimes described as “systems” or “network” perspectives emphasize that complex mixtures cannot always be fully understood by examining one component in isolation.

3. What “full-spectrum” concentration means here

In industrial and pharmaceutical settings, concentration and solid-state handling techniques (including crystallization) are often used to:

  • Increase material density

  • Improve stability and shelf behavior

  • Enable more consistent handling and formulation

In the context of complex extracts, a full-spectrum concentration approach applies these same physical principles to a multi-compound mixture, rather than to a purified single molecule.

The focus is on:

  • Retaining molecular diversity from the source material

  • Increasing consistency and concentration of the overall extract

  • Producing a solid or semi-solid form that is easier to formulate and protect

This approach emphasizes material properties—density, stability, and reproducibility—rather than biological claims.

4. Why this differs from “more milligrams of one thing”

Increasing the dose of an isolated compound simply increases the amount of that one molecule.

By contrast, concentrating a full-spectrum extract increases the density of the mixture itself: the relative presence of many co-occurring constituents is preserved as the material becomes more compact and manageable.

From a formulation standpoint, this distinction matters because it affects how an extract behaves during storage, blending, and delivery—independent of any specific biological outcome.

D. Liposomal delivery vs. conventional powders and capsules

Most plant and mushroom products are delivered as dry powders or standard capsules. These formats are widely used and can be appropriate in many contexts, but they place most of the burden on passive dissolution and digestion.

Lipid-based delivery formats, including liposomal and vesicle-based systems, are studied as an alternative way to physically organize compounds during digestion—without changing the molecules themselves.

1. What a lipid-based carrier is

Lipid-based carriers are structures formed from phospholipids or related fats—the same class of materials that make up biological membranes.

In vesicle-based formats, these lipids can organize into microscopic structures that associate with both water-soluble and fat-soluble constituents. From a materials perspective, this allows compounds with very different solubility profiles to be handled together in a more uniform physical system.

2. How lipid carriers change dispersion during digestion

Compared to dry powders, lipid-based formats can influence how compounds behave in the digestive environment:

  • They can improve physical dispersion of hydrophobic materials in aqueous fluids

  • They may reduce aggregation or clumping during transit

  • They can present compounds to the gut surface in a different physical context

These effects are discussed in the literature as changes in dispersion and presentation, rather than as guarantees of specific absorption outcomes.

3. Stability considerations in the GI environment

The gastrointestinal tract exposes materials to low pH, bile salts, enzymes, and mechanical mixing. Some compounds are sensitive to these conditions.

Encapsulation or association within lipid structures is studied as one way to:

  • Limit direct exposure to harsh gastric conditions

  • Reduce premature degradation of sensitive constituents

  • Maintain a more consistent material state during digestion

Results vary depending on compound type, formulation quality, and carrier structure.

4. Why delivery format is a formulation decision

Delivery format does not determine biological outcomes on its own, but it influences how consistently compounds are dispersed, protected, and handled during digestion.

From a formulation standpoint, lipid-based systems are best understood as physical carriers that can improve uniformity and robustness of complex extracts—rather than as performance-enhancing technologies.
