Serving: the amount the manufacturer states per serving on the label, for example 1 capsule. It is not always the full daily intake. Median: the middle price per serving, so half of the products cost less and half cost more. Cheapest and median only count products where Kelp is the main ingredient: the only active ingredient, at least half of the active ingredients' weight per serving, or, when every ingredient is a vitamin or mineral, listed first with at least half of the summed % of the nutrient reference value. Multi-ingredient formulas with nine or more active ingredients never count. Updated 2026-11-07.

How we calculate
Price per serving = price ÷ servings per pack. The count comes from serving data or pack quantity ÷ serving quantity in the same unit. ≈ marks a rounded count; price uses the unrounded count. The displayed serving is not always the full daily intake. Products without sufficient data are omitted.

How we calculate
Price per g = price ÷ (amount per serving × servings per pack). Products without a known serving count are left out rather than ranked on price ÷ amount per serving — that figure depends on serving size and reverses the order.
