For private label L-glutamine powder, specify the ingredient identity, the amount of L-glutamine in a full serving and the net fill. On a flavored quote, ask how much the scoop weighs and how much of it is L-glutamine. Then price both formats for the same amount of the ingredient per sellable pack.
Price the active ingredient across formats
| Illustrative quote | Actual L-glutamine in the pack | Cost per kilogram of L-glutamine |
|---|---|---|
| 60 plain servings of 5 g for 12 currency units | 300 g | 40 currency units |
| 30 flavored sachets with 5 g each for 10.50 | 150 g | 70 currency units |
In the sachet example, a 6 g fill contains 5 g of L-glutamine and 1 g of other ingredients. The sachet pack costs less per pack and more for the same amount of L-glutamine. That difference may make sense if you are selling individual sachets or offering samples at gyms. Compare quotes using the same delivery terms and include any separate carton or sachet printing cost. The Spartacus unflavored L-glutamine product is a published example of a 300 g multi-serve pack.
Request the identity and assay information
Specify L-glutamine by name on the request and have the supplier identify the ingredient source and testing method. Ask whether the assay result is reported on a dry basis or as the material is supplied. Request the batch identity and the finished-product release specification so you can trace a future reorder to the agreed formula. If you need a particular ingredient origin or production process documented, name it in the brief and ask what evidence accompanies each shipment.
Decide how customers will use the powder
For unflavored powder, test it in the liquid or mix you intend to describe and note any residue. For a flavored version, taste the complete formula and check whether changes to sweetness or acidity affect the proposed label. If you’re choosing between a pouch and a sachet, ask about fill consistency, opening and storage in the actual packaging. Check the case count for a sachet order and the scoop weight for a multi-serve pouch.
A white label L-glutamine project may involve a stock single-ingredient powder and a choice of fill or label. Ask which pack formats are already qualified. If you request a new flavor, ask for a separate formula code so your next order can reference the exact recipe.
For private-label glutamine, confirm raw-material identity and the site responsible for filling and labeling the proposed packs. Spartacus documents its existing manufacturing and Jordan packing arrangement; obtain product-specific documents rather than copying country-of-origin language from another supplement.
For a stock L-glutamine powder, ask whether changing from a plain tub to a flavored pouch changes the active grams per finished serving, artwork or minimum order. Compare these decisions using the white label stock formula guide.
Send the destination, target L-glutamine per serving, expected servings, packaging, first-run quantity and flavor decision via Spartacus private label enquiries. If the line also includes a ratio-based amino blend, see the private label BCAA buying guide. For another single-ingredient brief, compare the creatine private label guide.
Match the glutamine assay to your finished pack
A 300 g unflavored powder and a 300 g flavored powder need not deliver the same total grams of L-glutamine. Require the assay basis, identification method, actual active grams and batch traceability for the specific quote. Check the published company certificates for their stated business scope, but request separate batch records for the customer-label product. The existing Spartacus glutamine listing is only a reference pack; final ingredients, fill and availability must be agreed through private-label enquiries.
