The Evidence Gap
A formula can contain researched ingredients without reproducing the researched doses or outcomes.
Interactions Within a Blend
Multiple ingredients can affect absorption, tolerability or adherence in ways single-ingredient trials do not capture.
Best Proof
The strongest product claim would be supported by a well-designed trial on the exact marketed formulation.
Practical Rule
Treat ingredient studies as plausibility evidence, not a guarantee of product performance.
