The Evidence Transfer Problem
A study on xylitol gum, a live probiotic strain or cranberry extract may be scientifically useful without proving a different chewable formula.
Evidence Distance
Exact finished-product trials are closest. Exact ingredient/strain trials using similar dose and route are next. Different doses, routes or preparations create more uncertainty.
Probiotic Evidence Does Not Automatically Prove a Postbiotic
Live microorganisms and non-live microbial preparations are not interchangeable labels. Study design must match the preparation.
Combining Studied Ingredients Does Not Create a Studied Formula
A combination can change dose, exposure and interactions. Multiple individually researched ingredients do not add up mathematically to product-level proof.
What Lack of a Product RCT Means
It does not prove the product cannot help anyone. It means confidence in predictable clinical benefit should be lower.
How We Phrase the DentaBiome Conclusion
We describe ingredient-level rationale where supported and keep finished-product uncertainty visible.
