In whole units
7 capsules = 5.6g for $0.699
This is the fewest whole capsules that hold at least one comparison dose (5g L-glutamine). It is shown for information only. Rankings do not use it, because rounding up changes the amount you get as well as the price.
- One comparison dose is 6.25 capsules, and capsules cannot be split. The smallest whole number that holds at least the 5 g comparison dose is 7 capsules, which hold 5.6 g.
- Printed on this bottle's own panel image (NTC_L-Glutamine_800MG_180CAP_400CC_SFP_Square_1.jpg) as "L-Glutamine 800mg" in a "Serving Size: 1 Capsule" serving, with "Servings Per Container: 180"; the front prints "800MG Per Serving | 180 Capsules | 180 Servings". The panel prints milligrams and we compare grams of L-glutamine, so 800 mg is recorded as 0.8 g (800 / 1,000), and the 5 g comparison dose is 6.25 of this label's one-capsule servings. The panel also prints "Acacia Fiber (Acacia senegal) (gum) 30mg" as a second dietary ingredient with its own amount, recorded as the second active; the price per 5 g of L-glutamine is not adjusted for it. The "GLUTEN-FREE" bullet on the side is what the gluten free answer rests on; no face makes a vegan or vegetarian claim, so both are Unknown.
Delivery
Delivery cost
Applies, amount not published
Delivery is NOT free on this order. It is $41.04 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 continental US shipping on orders above $59, from the site-wide banner, first read September 1, 2026: "FREE CONTINENTAL U.S. SHIPPING ON ALL ORDERS ABOVE $59". The policy page showed the same threshold on September 26, October 17 and November 1, 2026. The wording covers the continental US only, so the cost to Alaska, Hawaii and US territories is Unknown. No rate is published below the threshold. On September 1 and November 1, 2026 the site was also running a sitewide discount code that could not be combined with free shipping, so the advertised price and the checkout price can differ here.

Price history
Latest recorded price: $17.97 at Nutricost (direct), checked . Unchanged since we started checking on Oct 30 (16 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: Could not locate independent data
We could not locate independent testing or certification for this product. That is a statement about our search, not about the product. These programs certify what a company submits to them, so a product can be absent simply because it was never entered, which is not a finding against it. 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 for this product, and located no published test results. A program not named below was not checked for this product.
- Testing claim we recorded, and where it appeared: "THIRD PARTY TESTED" (a bullet on the side of the label, naming no program and no laboratory). The claim names no program we grade, so there is no listing to check it against. It does not raise the verification level.
- Checked NSF Certified for Sport database on Oct 30, 2026: not listed.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. NSF's whole Certified for Sport directory was read on Oct 30, 2026, 2,593 listings, and holds no row filed under Nutricost, in this category or any other. None of the 14 listings whose product name contains "glutamine" is this brand's. The label on this package prints no NSF mark. Absence from a database is not a failed test.

Not being listed is not a failed test.
