Mechanism means pathway

Mechanism of action describes how a compound may interact with receptors, enzymes, signaling pathways, or biological systems.

Pathway evidence is not outcome proof

Showing a pathway signal does not automatically prove a clinical benefit, treatment effect, or real-world result.

Look for evidence layers

Better research reading separates molecular data, animal models, human endpoints, approved indications, and post-market evidence.

Marketing often compresses the story

Be cautious when a page jumps from a mechanism to a guaranteed outcome without showing the evidence chain.
