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.

Compare forms

L-Tryptofan by chemical form in our catalog: how many products, typical amount and what a serving costs. Medians from live data, not marketing.

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.
