- This bag has no published panel of its own. It is entered from the 500 g bag's panel image (L-Glutamine-Powder-500g-Label-V008.jpg), which prints "L-Glutamine 5g" in a "Serving Size: 2 tsp (about 5 grams)" serving, and from its own bag front on the same page (L-Glutamine-Powder-1kg-Main-Image-V003.jpg), which prints "5g PER SERVING / 1kg WEIGHT / 200 SERVINGS / NET WT. 35.3 oz (2.2 lb) (1 kg)", together with the store feed, whose variant "Powder / 1 Kilogram (2.2 lbs)", SKU GLUT1KG, states the package. A size with no panel of its own is entered this way only when its serving is the read panel's, so the serving and the other ingredients here are that panel's. We compare grams of L-glutamine, and that panel prints grams, so nothing is converted. The read panel's GLUTEN FREE icon is what the gluten free answer rests on; no face makes a vegan or vegetarian claim.
Delivery
Delivery cost
Applies, amount not published
Delivery is NOT free on this order. It is $19.04 short of free delivery (orders over $59.00). This retailer does not publish one fixed delivery rate, so we cannot tell you exactly what delivery will add. Free delivery on orders over $59 within the contiguous US. Below that, the rate is calculated at checkout and is not published in advance. Alaska, Hawaii and Puerto Rico may incur extra charges by weight. Read again on October 30, 2026 with the same terms.

Price history
Latest recorded price: $39.97 at BulkSupplements.com, checked . Unchanged since we started checking on Oct 30 (14 checks).
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 level D: Entry found, not settled
A certifier’s directory holds an entry that may cover this product. Whether it names this package is not settled either way, so it is neither a listing nor an absence, and it is not a finding against the product. The databases we searched, and when, are listed below. If a program is not listed, we did not check it, and we make no claim about it either way.
- Searched 4 certifier databases and found no listing settled as naming this product, and located no published test results. A certifier's directory holds an entry (1797920) that may cover this package; whether it does is not settled either way. A program not named below was not checked for this product.
- Testing claim we recorded, and where it appeared: "THIRD PARTY TESTED" (one of three seals on a "TRUSTED QUALITY" image in the gallery of the store page this site's Buy link opens, read Oct 30, 2026). It names no laboratory and no program. There is no listing to check it against. It does not raise the verification level.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: not settled (1797920)
Listing 1797920 "L GLUTAMINE", Bulk Supplements, read on Oct 30, 2026, prints Product Form Powder, Package Size "100 g, 250 g, 500 g, and 1kg" and Serving Size "2 tsp (~4 g)". The store sells this bag as "Powder / 1 Kilogram (2.2 lbs)", a weight the listing names, and the 500 g bag's panel, which this bag is entered from, prints "Serving Size: 2 tsp (about 5 grams)". The label image the listing itself files prints the same "2 tsp (about 5 grams)" serving and "L-Glutamine 5g". The package weight matches and the serving weight on the listing differs from the label's, so whether the listing names this package as it is labeled is not settled either way. No image the store publishes of this bag shows an NSF mark.
The program's directory holds an entry (1797920) that may cover this package. Whether it names this package is not settled either way, so this row is neither a listing nor an absence.

Checked and absent. We read all 16 pages of USP's own Verified Products directory in a browser on Sep 21, 2026: 159 products from 16 brands. We saved a copy. This brand is not in it: not in the directory's brand filter, and not in any product name. USP verifies the products a company submits to it, so this shows only which products were submitted. Not being listed is not a failed test.
