A “Custom” Manufacturer

At Sentry we specialize in “customizing” our manufacturing of nutritional supplements to your specific requirements. We can duplicate an existing product – from formulation to precise matching of appearance, or we can start with a general conception. We have the capacity to handle large orders, and the flexibility and patience to handle the most difficult products. At Sentry, we keep to strict delivery schedules, but we have the concern and ability to meet your unforeseen “emergencies.” We have built our business around your needs, not our convenience.

Custom Solutions for Customer Needs

In almost two decades of custom manufacturing, Sentry has serviced some of the largest names in the business as well as many “start-ups.” We pride ourselves on helping many newcomers become major brands: by developing their concepts, producing superior products in a timely and cost-effective manner, keeping up with their growing needs and ahead in a competitive marketplace. We service all aspects of the nutritional market: chain stores, distributors, mass-merchants, mail-order and multi-level marketers. Sentry has developed a varied and veritable customer list in the U.S. and abroad because our manufacturing system is designed with the built-in flexibility and diversity they require.


At Sentry we specialize in solving your custom manufacturing problems. Whether you are having a problem with the quality of your product or its mass appeal, we can help. If you are not getting deliveries on time or you’re being priced out of the market, give us a try. Let us take care of the custom manufacturing of your product, and you concentrate on what you do best – selling it. Remember we are the private label manufacturer for the start ups as well as some of the largest PL customers.

Product Development

Product development is the process of understanding and developing your product to meet your marketing objectives and making sure that the product is shelf stable over the life of the product, maintains its integrity through your marketing cycle and has the content uniformity and dissolution characteristics that are required to make an effective product


Product development starts at the inception of a product idea. In developing the products, the following factors are taken into consideration:

  • Physical and chemical compatibility of the different active ingredients
  • Effect of the ingredients over the shelf life of the product in terms of physical appearance and organolpetic characteristics
  • Market that the product will be sold in (market perceptions, temperature and humidity variables etc.)
  • Ability to have process repeatability without variations so that you get a consistent product
  • Ability to prolong the shelf life to meet specific market requirements

All these factors are taken into consideration in developing a product. The product development phase at Sentry Manufacturing, Inc is a very rapid phase thanks to the years of experience that the staff provides. We actively communicate with our customers so that they are kept abreast of all the issues.


A vast majority of our customers have come to us as they have been dissatisfied with some of our competitors over product development, quality, delivery times, professionalism and a host of other factors.


Throw us a challenge and put our product development team to the test.
