What is the cheapest NSF certified L-glutamine?
Latest price check:
BulkSupplements.com L-Glutamine Powder, Mango Tango (700 g), BulkSupplements.com L-Glutamine Powder, Lemon Italian Ice (700 g) and BulkSupplements.com L-Glutamine Powder, Sour Apple (700 g) tie as the cheapest per 5g, each at $0.34 before delivery.
6 of the 32 L-glutamine products we track have their exact package named in NSF's Certified for Sport database. That is a stricter test than “the brand is NSF certified”, and it is deliberately so: NSF lists package sizes against each certificate, and a size it does not name is not one it has stood behind. Each price is delivered where the retailer publishes a delivery rate and before delivery where it does not, and each row says which. 2 more L-glutamine packages, from Sports Research, are certified by Informed Sport, whose listings name no package size, so they are not in the tables below, which rank only packages NSF names. A pick can still be one of them, because the pick uses the category's own bar. Every brand, by program: Which L-glutamine brands are third-party tested?

NSF's listing names another package
NSF's listing names these products in another form, not the packages we price. NSF has not put its name to these packages.

- BulkSupplements.com L-Glutamine 5,000 mg (360 capsules) ($0.433 per 5g, before delivery)

NSF's directory holds an entry that may name these packages, and whether it does is not settled either way, so they are not ranked here. Each product page says what the entry prints and where it differs.
- BulkSupplements.com L-Glutamine Powder, Unflavored (100 g) ($1.05 per 5g, before delivery)
- BulkSupplements.com L-Glutamine Powder, Unflavored (250 g) ($0.479 per 5g, before delivery)

Cheapest among the 6 L-glutamine packages we track that NSF names at the exact package, not the cheapest that exists. NSF certifies L-glutamine from more brands than we carry, and our catalog is extended brand by brand, so a certified product we have not added yet cannot appear here however cheap it is.

Where to buy: the L-glutamine shortlist
The pick is the cheapest product that clears four bars:
- certified, and named at the exact package where the certifier names packages
- no adverse finding on record
- a price its retailer let us read recently
- no more than a year’s supply at the label’s serving
It is ranked 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 other answer beside it is the cheapest under a different rule, and its own line names that rule. Answers that cost more than the pick are folded into one line until you open it.
How these lines are chosen
Among 27 products and 27 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of 5g, priced the same way as the figure beside it. It is worked out before that figure is rounded, so it can differ from thirty times it by a few cents. It is not thirty servings where a serving holds more or less than 5g. “Delivery known” ranks only products whose retailer publishes a delivery rate. A cheaper tested product whose rate is not published gets a line of its own. Every package we price, with its delivery terms, is on the L-Glutamine page.

A pick has to clear four bars:
- independently certified, and named at the exact package where the certifier names packages
- no recall or failed test
- a price its retailer let us read recently
- no more than a year’s supply at the label’s serving
Where the retailer publishes no delivery rate, the pick is priced before delivery and says so. Nothing we track here clears all of those yet. Each of these misses at least one bar, and says which:

What this rests on: Prices are the last ones we recorded at the retailer named on each product page. Prices go stale, so each page says when it was checked. We track some products, not every one sold, and Amazon and Walmart are not among our stores. Listings and labels are read at the source, and each page links to them. Found an error? Tell us.
