Why this matters
Learn how formulation, storage, and delivery differ from proof of a health benefit.
How the pieces connect
Products can differ in stability, storage, and delivery. Ask which formulation and route were studied and what benefit was measured.
Three product questions that should stay separate
Stability asks whether a preparation maintains its intended composition. Bioavailability asks how much reaches a relevant site after administration. Clinical efficacy asks whether using it improves a meaningful outcome. A preparation can answer one question well while leaving another unanswered. Dr. Purser discusses all three around reduced glutathione, but they should not be collapsed into a single claim of “functionality.” The formulation, route and study population must match the claim being considered.
Keep in mind
A patent or delivery claim tells you about a product idea, not whether it treats disease. Ask for evidence about the specific formulation and the health outcome you care about.
