Supplement Price Comparisons

Two bottles can have the same sticker price and very different monthly cost once serving size, active ingredient amount, and servings per container are included. TrueServing normalizes each comparison around the category's reference daily dose so shoppers can compare products on the same monthly basis, even when one listing uses capsules and another uses powder, softgels, gummies, tablets, or liquid servings.

The comparison pages use active ingredient amount and servings per container from Supplement Facts labels when those fields can be verified. Product-title claims are not treated as reliable extraction data because titles often mix serving size, multi-capsule doses, and marketing language.

Products need current price data, a readable active ingredient amount, and a usable serving count to appear in the ranking table. Combination products may be excluded when another primary active ingredient would make the category comparison unfair.
