Whey, isolate or plant protein
Protein source drives cost, taste and label claims. Ask which proteins a maker stocks (whey concentrate, isolate, plant blends), how flavor systems are developed, and whether it fills tubs, pouches and stick packs in-house.
Verify the protein claim
Ask for batch Certificates of Analysis showing protein content, and whether added free amino acids are counted toward it, a known way labels get inflated. For sports buyers, third-party programs such as NSF Certified for Sport or Informed Choice add a further check; see sports nutrition makers.
Frequently asked questions
What is the minimum order for private label protein powder?
15 of the 47 makers here publish a minimum order. The lowest are Custom Nutra (48 units), Reliance Vitamin (144 units), Green Star Labs (250 units), Makers Nutrition (500 units). Most quote per project. Custom flavors usually raise minimums. Compare stock programs on the private label hub.
How do I check the protein content is accurate?
Request a batch Certificate of Analysis for protein content and ask how added amino acids are treated. A third-party certification program adds independent testing on top.
Can I get protein powder in stick packs?
Yes, if the maker runs a stick-pack line. The formats column above shows which makers list stick packs; confirm single-serve fill weights with them.
