Compare every L-Proline product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Non-essential amino acid critical for collagen synthesis and wound healing
We rank L-Proline by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
How Suppio ranks Suppio matches identical products across UK retailers by barcode, then ranks by price per active dose rather than sticker price. Value rankings only ever include listings Suppio has independently verified against the live retailer page - unverified data is shown on each product’s own page but excluded from ranking.
Prices across our retailer network are refreshed at least daily.
