Compared on the evidence
Multi-Ingredient Formulas
A formula bundles several ingredients into one bottle. That is convenient, but it is also where under-dosing and proprietary blends hide. Read the label before the marketing.
The products below list every ingredient and its amount. That alone rules out most of the category.
