Bulk Vitamins

Omni Ingredients is a bulk vitamin supplier for supplement brands, contract manufacturers and distributors. The range covers vitamin C and mineral ascorbates, the B-complex vitamins including coenzyme forms such as methylcobalamin, vitamins A, D3, E and K, and related nutrients such as inositol and choline, all sold wholesale by the kilogram with pound and gram conversions available for quoting. The same vitamin is often supplied in several chemical forms, strengths and dilutions, so the grade matters as much as the name. Items marked “In stock - US” ship from our warehouses in Ontario (California), Dallas (Texas) and Buford (Georgia); items marked “Made to order” are sourced for your order through vetted, cGMP-compliant manufacturing partners. Every lot is batch-numbered, with its certificate of analysis supplied with the shipment or on request.

What to specify in your quote request

Specify the chemical form, such as the salt, ester or coenzyme form, and whether you need the pure material or a diluted, coated, spray-dried or cold-water-dispersible grade. State potency on the basis your label uses (IU or weight) and the compendial standard if your specification cites one. If your process calls for a coated, granular or direct-compression grade, name it: we will source and quote against it. Include your storage and shelf-life requirements for sensitive vitamins, and ask for the current lot's COA with the quote.
