Every category ranked by the one number that decides what you actually pay: the cost of a single serving. Tub price is misleading — a bigger, pricier tub often works out cheaper per serving than a small cheap one.
To keep it honest, a product only appears once it passes our Effectiveness Match bar (score 50+), so the cheapest pick still actually works. Want the best effectiveness per pound instead of the flat cheapest? See Best Value.
Cheapest Per Serving
The lowest cost-per-serving picks across every category that still pass our dosing bar.
Cost per serving is simply the retail price divided by the servings in the container. We rank the products that pass our Effectiveness Match bar (score 50+) from cheapest per serving upward, so you get the lowest price for a dose that still works — not the lowest price full stop. Rankings recalculate as prices change.
