Bulk Amino Acids & Proteins

Omni Ingredients is a bulk amino acid and protein supplier for supplement, sports nutrition and functional food manufacturing. The category includes free-form L-amino acids and their salt forms, branched-chain amino acids, creatine, carnitine forms, amino acid derivatives, and protein and collagen powders, all sold wholesale by the kilogram with pound and gram conversions available for quoting. Items marked “In stock - US” ship from our domestic warehouse network; items marked “Made to order” are sourced for your order through vetted, cGMP-compliant manufacturing partners. Each lot carries its own batch number, carried onto the shipping paperwork, and its certificate of analysis is supplied with the shipment or on request, which is what lets you set one delivery against the next on equal terms.

What to specify in your quote request

Name the exact form your formula uses: the free base or a salt form such as the hydrochloride (HCl), the L- or DL- form, and for creatine, carnitine and similar materials, the specific compound. These are different materials with different assay bases, so two quotes are only comparable when the form matches. Add the assay and any compendial standard your specification cites (for example USP), the particle size or mesh, and whether you need an instantized grade for powder mixes. For protein and collagen powders, state the source material and the protein basis your label is built on.
