Products of the dietary supplement industry

Dietary supplements represent an active lifestyle, conscious nutrition, and the desire for targeted support for health and performance. The industry is creative, driven by innovation, and close to the end consumer – at the same time, quality, safety, and consistency are more important than ever today. 

The product range includes vitamin and mineral mixtures, protein powders, functional blends, and specialized formulations with probiotics, plant extracts, or bioactive substances. Regardless of the product concept, the actual quality is created in the manufacturing process. Only when active ingredients are evenly distributed can a dietary supplement reliably work. 

Many products are produced as sophisticated powder blends. This combination places high demands on the mixing technology – especially when precision, product protection, and reproducibility are required simultaneously.

Typical products and terms in the dietary supplement industry:

- Dietary Supplements

- Vitamin and mineral mixtures

- Protein powders (Whey, Casein, plant-based proteins)

- Sports nutrition and Functional Nutrition

- Functional blends and active ingredient mixtures

- Probiotics and prebiotics

- Plant extracts and bioactive substances

- Instant drink powders

- Clean-label and allergen-free formulations

- Dietary products and specialty foods

Requirements for mixing and refining

Formulations for dietary supplements are often highly concentrated and finely tuned. Vitamins, trace elements, or bioactive ingredients must be distributed precisely so that each portion delivers on its promises. Even small inhomogeneities can affect dosing accuracy during packaging – and thus product efficacy. 

At the same time, many ingredients are sensitive to mechanical stress or unwanted heating. Proteins, probiotics, or certain plant extracts should maintain their structure and not be compromised by the process. Therefore, mixing processes that are highly controlled yet efficient are required. 

Many dietary supplements only achieve their functionality through liquid components – such as carrier oils, flavors, or lipophilic active ingredients. The challenge is to incorporate these liquids in a way that they disperse inconspicuously and evenly in the powder, without causing the product to clump or lose its dosing and filling capability. 

amixon® mixers enable a controlled, process-safe integration of liquid components directly during the mixing process. The liquid is finely distributed, follows the product movement, and supports homogeneous wetting without compromising the powder's structure or leading to an undesired temperature increase. 

In addition, there are high demands for hygiene, cleanability, and product changeovers. Allergen management, clean label concepts, and frequently changing formulations are commonplace in the dietary supplement industry – not least due to the proximity to pharmaceutical quality requirements.

amixon® solutions for dietary supplements

amixon® develops and builds mixers, dryers, and reactors for dietary supplements, where precision, product protection, and hygienic safety must come together. The technology is designed to reliably distribute highly effective ingredients - even when they are only used in very small quantities.

The amixon® Conical Single Shaft Mixer (AM) is particularly suitable for flexible product lines and frequent recipe changes. The conical design ensures uniform product movement and nearly complete emptying. Product losses are minimized, cleaning processes are simplified, and the safe switch between different active ingredient profiles is supported.

The amixon® Vertical Two-Shaft Mixer (HM) is the right choice when larger batches need to be processed and a very uniform distribution of active ingredients is required. It enables short mixing times and stable results - even with formulations with greatly varying densities and particle sizes.

The amixon® KoneSlid® mixer (KS) was developed for applications where the smallest amounts of active ingredients need to be precisely distributed. Controlled discharge prevents demixing during discharge and contributes to constant dosing accuracy throughout the entire batch.

The amixon® Spherhelics® Mixer (SH) complements the portfolio with a unique mixing principle and is also the entry into the world of amixon® precision mixers. It is used when simple, uniform product movement and stable mixing conditions are paramount - for example, with sensitive or particularly valuable formulations.

amixon® develops and builds industrial mixers and process technology for hygienic, reproducible powder processes in the dietary supplement industry.

Typical process engineering applications in dietary supplements:

- homogeneous distribution of vitamins, minerals, and active ingredients

- safe mixing of very small dosing components

- processing of protein powders and functional blends

- uniform integration of liquid additives such as oils or flavors

- controlled discharge to prevent demixing

- hygienic processes close to pharmaceutical regulations

Technical center and process development

At the amixon® Technology Center, mixing and refining processes can be tested in a practical manner - with original recipes and realistic process conditions. Mixing quality, liquid addition, emptying, and cleanability are evaluated together and prepared specifically for industrial use.

This creates security - for product quality, scalability, and market introduction.

Dietary supplements are more than just powder. They are part of a lifestyle - and manufacturers have a responsibility. To meet this demand, it takes process technology that works precisely, gently, and reliably. amixon® develops and builds mixers, dryers, and reactors for this purpose. Let's talk about your products, your ideas, and your next steps. amixon® - Process technology for dietary supplements with high standards.

FAQ

Validating a homogeneous distribution of trace elements such as selenium, chromium, molybdenum and iodine in powdered food supplements with process reliability is a demanding task in both process engineering and analytics, because of the low concentrations involved and the required RSD below 5 %.

amixon® solves this with precision mixers (KS, HM, VM) that produce a technically ideal random mixture – independently of the fill level from 10 to 100 %. Low circumferential speeds of approximately 0.8 m/s keep the mixture cool. The GMP-compliant hygienic design from amixon® allows residual discharge of 99.997 % and better. The coefficient of variation of the mixing quality is below 5 %; even values around 1 % are achievable.

The scalability of a laboratory mixer depends above all on geometry, process parameters, material properties and the product quality verified. The decisive point is that homogeneity and active ingredient distribution remain reproducible from laboratory to production scale, using suitable analyses and pilot trials.

amixon® turns scale-up into a secured transfer: pilot-plant and production mixers work with an identical mixing principle – the SinConvex® tool at the same circumferential speed of 0.8 to 3.5 m/s – mixing quality is independent of the fill level, and sizes can be selected in 100-litre increments up to 50,000 litres. The parameters are validated in advance in the pilot plant with the original product.
