Ingredient claims are not treatment proof
Sexual-health marketing often connects an ingredient to nitric oxide, testosterone, circulation or libido and then jumps to a treatment conclusion. Each step needs evidence. Mechanistic plausibility alone does not establish that a specific product treats ED.
How to assess each ingredient
Check whether human studies exist, what outcome they measured, dose and duration, sample size, safety, interactions and whether the studied preparation matches the marketed one.
