Is BUBS collagen NSF certified?
Yes, for every BUBS Naturals product we track in this category. NSF lists a specific package against each certificate, and a certificate is what NSF actually stands behind, so a package the listing does not name is treated as unconfirmed rather than certified. Every row below was read against NSF's own listing, and the listing ID is shown.
NSF holds one listing for the brand’s collagen tubs, naming both sizes, and a separate listing for the travel pack of stick packs. Each row below says which.

What the listings say
BUBS Naturals holds 2 Certified for Sport listings covering the products in this table (1802301, 1531712). NSF records some brands under more than one spelling, so a search on the brand name alone can miss a listing; ours are found from a full read of the directory, then opened one by one.

Where to buy: the collagen peptides shortlist
The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows. Any answer shown beside it is the cheapest under a different rule and says so on its own line; answers that cost more than the pick fold under one line until you ask for them.
How these lines are chosen
Among 33 products and 33 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 “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
