Collagen Peptides
Capsules and powders are ranked separately: each has its own table, and neither is priced against the other.

Cheapest independently tested, delivery known
Sports Research Collagen Peptides, Unflavored (32 oz)$0.665per 10g, delivered$19.94 a month
Not our pick: its price is 10 days old and we cannot refresh it automatically.
Last known price, Oct 17, 2026; we have no automatic way to refresh Sports Research (direct)'s prices.
Cheapest independently tested, before delivery
BulkSupplements.com Collagen Peptides Powder (Bovine), Unflavored (500 g)$0.565per 10g, before delivery$16.95 a month
Not our pick: delivery cost is not published.
Delivery is extra and not published; free from $59.00.
How these lines are chosen
Among 44 products and 44 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.
Why this pick, and what's cheaper
Not a score, no weightings to argue with. It is the cheapest per delivered dose among products clearing four factual bars (a certification we confirmed applies to this package, naming it where the certifier names packages; no recall, warning letter or failed test in the sources we checked; a price its retailer let us read within its cache limit; no more than a year's supply at the label's serving) and whose delivery cost we actually know. It is provisional: it is the best answer within the products, retailers and sources we have actually checked, and that universe is still narrow.
Core Med Science is $25.00 short of free delivery, worth it if you are buying something else anyway, at $1.11/dose, tier A.
Sports Research $0.665 is cheaper, but its price is 10 days old and we cannot refresh it automatically.
Capsules, softgels and tablets
Nothing here clears every bar, so there is no pick
A pick has to be independently certified, at the exact package sold where the certifier names packages, with no recall or failed test, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving. Where a retailer does not publish a delivery rate, the pick is priced before delivery and says so. This came closest, with what stopped it:
BulkSupplements.com Marine Collagen (Fish) Capsules (300 capsules) $1.40 per 10g, before delivery, no independent verification we could locate; delivery cost is not published. Free delivery starts at $59.00, so this order is $38.03 short.
“Delivery cost is not published” usually means the retailer only publishes a free-delivery threshold and no rate below it. An order that reaches the threshold clears it. We cannot price that cart for you, so we show the gap instead of guessing.
Hydrolyzed collagen sold by the scoop, and the scoops are not the same size from one brand to the next. Every product here is priced per 10 g of collagen peptides as its own panel prints them, whatever the scoop, the source animal or the tub.
Prices are checked daily where a store can be read automatically; Sports Research is read by hand, less often, and a price past its date says so. Every figure links to its source. Where the data comes from
Of the 45 products here: 8 named at the exact package by a certifier, 6 certified with no package named, 4 at another size only, 27 in no database we searched.
Powder
44 of 44 products
32 rows marked + delivery exclude an unpublished delivery charge, so their real cost per dose is higher.

About these numbers
What “per dose” means here: 10g collagen peptides
Randomized trials of collagen peptides used 2.5 to 10 g a day of collagen hydrolysate in dermatology (Choi et al. 2019) and 15 g a day where collagen synthesis was measured with exercise (Khatri et al. 2021). Labels in this category print scoops of different sizes. 10 g sits inside that studied range and is a round number, chosen so products with different scoop sizes can be priced against each other. It is a yardstick for comparing prices, not a recommended intake, and it cannot change which product is cheapest: it scales every row in the category by the same number.
Compared on grams of collagen peptides (hydrolyzed collagen) per serving, as the Supplement Facts panel prints them in the ingredient line, not on the Protein line and not on the scoop. Scoop sizes differ from one label to the next, and a label can print a protein figure a gram or two below its collagen figure, so per-scoop and per-tub prices are not comparable. Bovine, marine and multi-source collagen are shown as what the panel names; a product whose panel prints only a milligram dose of undenatured type II collagen is a different product and is not entered here.
Where the data comes from
Every claim links to its source. Products, prices and certification listings are read from the retailers' own stores and the certifiers' own databases, and each figure links to the record it came from, so you can check any of them.
- Where a servings-per-container figure was not read from the package's own panel, the product page says how it was worked out.
- Amazon and Walmart are not included, so “cheapest” means cheapest among the retailers we track.
- Prices go stale. Each one shows when it was last checked, and says so when it is older than the retailer allows us to cache it.
- iHerb prices cannot be refreshed automatically. iHerb has not given us access to its price data, so those prices are marked stale until they are re-read. Each retailer offer carries its own check date.
Found something wrong? Tell us. Corrections are the point.
How we make money
No Buy button on this page earns us anything. The only links on the site that can are the Amazon links shown below the price comparison on some product pages, outside the comparison, and each says so beside it.
Commission will play no part in what we list, how it ranks, or which link we send you to. The Buy button points at the lowest price we have recorded even when that retailer pays us nothing.
