Undenatured describes preservation of structure
The review distinguishes native collagen prepared under conditions intended to preserve its triple helix from denatured or hydrolyzed materials. Type II identifies a collagen type; undenatured describes its structural state. [1]
An equal mass of a hydrolyzed product is not automatically equivalent to a native type II preparation. The molecular form is part of the intervention being studied. [1]
Oral tolerance is a proposed explanation, not a universal result
The review discusses oral tolerance as a proposed mechanism involving immune recognition of native type II collagen. This is different from simply supplying dietary protein fragments. [1]
All review authors were employees of a collagen-ingredient manufacturer. This page explains the proposed distinction; it does not independently establish clinical effectiveness, select a dose or imply treatment of autoimmune arthritis. [1]
Keep form attached to the claim
Imagine evidence concerns a native type II preparation but a product contains hydrolyzed type I collagen. The different structure and ingredient identity prevent a direct assumption of the same effect.
| Detail | Interpretation |
|---|---|
| Type II | Collagen identity |
| Undenatured | Structural state |
| Proposed mechanism | Not guaranteed clinical benefit |
