Production of Dietary Supplements in IOC step by step

W IOC we have modern technological facilities that allow us to produce dietary supplements in various forms. Our plant is equipped with advanced machinery and technologies, which allows us to produce a wide range of supplements tailored to the individual needs of our customers.

Key Aspects of the Production Process

Each stage of production is carried out with the utmost attention to quality. From the selection of raw materials, through production processes, to final packaging - each step is carefully monitored. We use raw materials only from proven suppliers, which guarantees that our products are safe and effective.

Weighing Raw Materials – The Beginning of the Process

Weighing raw materials is the first step in our production. In this phase, we carefully measure each ingredient to ensure optimal proportions. This is crucial to achieving consistency and effectiveness in the final product.

Mixing Ingredients – The Heart of the Process

After precise weighing, the raw materials are mixed. This phase is extremely important because it ensures even distribution of ingredients throughout the product. We use specialized mixing machines that guarantee perfect consistency and homogeneity of the mixture.

Variety of Capsule Forms – Adaptation to Requirements

The next step in our production process is encapsulation. We specialize in creating various forms of capsules, which allows us to adapt the product to the specific needs of our customers:

  • Hard Capsules: Available in sizes "0" and "00", ideal for standard supplement doses.
  • Soft Gel Capsules: Flexible in formulation, ideal for oily ingredients and larger doses.

Packing – The Last Stage of the Process

After the encapsulation process, we start packaging. We offer various packaging options, including sachets, containers and bottles. Each of these packaging options is tailored to the different needs of our customers, ensuring the safety and long-term storage of the product.

Pouring the Mixture/Granulate into Sachets

The sachets are ideal for packaging powder or granules. They are easy to use and allow you to quickly prepare single doses of the product. The sachets are also convenient to transport and store.

Pouring Liquid and Semi-Liquid Forms

In our production plant, we also have the ability to pour supplements in liquid and semi-liquid forms. This option is particularly beneficial for products that require quick absorption by the body, as well as for customers who prefer an alternative to tablets or capsules. Our production lines are adapted to bottling various types of liquids, from syrups to vitamin and oil mixtures.
