S3* · Biological reality check

What survives, becomes accessible and can be absorbed?

A plant may contain a compound without delivering it to the body in the same form, dose or amount.

Verification layer · applies across topics

Basic structure

Presence is not delivery.

Processing, storage, digestion and the food matrix can enhance, delay, reduce or transform the release of plant compounds.

S3* checks the distance between what analysis finds in a product and what can realistically become available to the body.

Track processing and storage before consumption.

Distinguish bioaccessibility from bioavailability.

Consider digestion, conversion and the role of the gut microbiota.

Connect absorbed amount to realistic dose and product form.

Test the finished formulation when product-level meaning is required.

Page architecture

This is the structural layer. Paper-level evidence and references will be added only after the architecture is approved.

Step 01

The fraction released from the food matrix during digestion and available for intestinal uptake.

Step 02

The fraction that reaches systemic circulation and becomes available for biological use.

Step 03

Transport, metabolism, tissue exposure and the difference between a measurable compound and a meaningful effect.

Scientific boundary

S3* interrupts the shortcut: plant contains X → person receives effect Y. Every arrow in that statement must be demonstrated.
