Testosterone-booster ingredients: evidence is not interchangeable

Research on one ingredient, dose or population cannot automatically establish that a multi-ingredient commercial formula produces the same result.

Ingredient evidence hierarchy

Give more weight to well-designed human trials and systematic reviews than to mechanistic theories, animal studies, testimonials or marketing copy. Match the studied ingredient form, dose, population and outcome to the claim.

Finished product vs. ingredient evidence

Evidence for an isolated ingredient does not automatically substantiate a multi-ingredient finished product. FTC guidance specifically warns that a “clinically tested ingredient” message can imply benefits for the finished product when that inference is not established.
