Why contract Frontier to manufacture your custom formulation? Frontier has both international and domestic contacts with ingredient distributors and manufacturers. If a particular constituent is not stocked as part of our inventory, we can source a quality provider and have the material delivered to our facility. Our manufacturing process is part of a quality program that ensures all of our diet batches are made to specifications and meet our clients needs. If your formulation is proprietary we offer NDA’s to ensure your IP is protected when working with Frontier.
