L-Prolin — product comparison

Rankings from our live catalog (53 products with measured amounts). Not affiliate lists — our own structured ingredient data.

Products: 6; +47 more also contain L-Prolin
Structured dose: 33 %; 2 / 6

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 L-Prolin 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 2026-10-31.

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

No form data for L-Prolin yet.

Best value (lowest price per g)

Measure shown: price per g of L-Prolin across the whole pack

We cannot calculate price per mg for L-Prolin yet — it requires a known number of servings per pack.

Only products with L-Prolin as the main ingredient. Others are listed under Also contains L-Prolin

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.
