Thorne Whey Protein Isolate, Vanilla, Travel Packs (14 packets)

Cost

• Grams of protein per serving as printed on this carton's own panel: "Protein 21 g" in a "Serving Size: One Packet (27.9 g)" serving with "Servings Per Container: 14". The panel also prints "Whey Protein Isolate 25 g" on a separate line; the protein line is what the comparison uses, as it does for every other product in this category. The carton prints "14 - 0.98 OZ (27.9 G) / TOTAL NET WT 13.78 OZ (390.6 G)"; net weight is deliberately not recorded for whey, because the basis is the protein in the package and the two must not be divided into each other. The same packet carries a 30 mg Proprietary Blend of bromelain and papain, which is priced nowhere. The page's own ingredient block prints no Protein line at all, so this rests on the panel image.

Where to buy

Ordered by price, lowest first, and labeled so you can see what each link earns us. Commission is never an input to that ordering. If the cheapest retailer pays us nothing, that is still the one we send you to. No link on this page earns us anything; every Buy button is a plain retailer link.

We check each price about once a day, so this is the range we recorded, not necessarily every price there has been. It says what changed, not why, and nothing about where the price goes next.

Verification, Tier A?: Independently certified, package unconfirmed

A certification program lists this product, but its listing does not name the package size priced here, so we do not present it as an unqualified certification. The listing, and exactly what it does and does not cover, is set out below.

• NSF Certified for Sport lists this product, but the listing does not cover the package size shown here. Listed at another size. Listing 1513728 "Thorne® Whey Protein Isolate Vanilla Flavored" prints Package Size "29.7 g, 906 g" with Serving Size "1 scoop (27.9 g)", and its Protein 21 g, Carbohydrate 3 g, Sugar 3 g, Fat 0.5 g and Calories 100 Cal are this formula's figures. The package priced here is the 14-packet carton, whose front prints "14 PACKETS / 14 - 0.98 OZ (27.9 G) / TOTAL NET WT 13.78 OZ (390.6 G)" and whose panel prints "Serving Size: One Packet (27.9 g)" and "Servings Per Container: 14". Neither 390.6 g nor a packet count appears on the listing: 906 g is the chocolate tub's net weight, and the label image the listing publishes prints "Serving Size: One Scoop (27.9 g)" and "Servings Per Container: 30", which is the vanilla tub's panel. The listing's "29.7 g" appears nowhere on this label and its own Serving Size line gives 27.9 g, the same mismatch noted for the vanilla tub. Under the package rule this carton is recorded as listed at another size. The carton's own back face prints the NSF Certified for Sport mark, which is recorded as the maker's claim on the product.
