Manufacturing countries
Our products are manufactured exclusively in Germany, more precisely in Bavaria.

Manufacturer selection
Only the best manufacturers are approved by Dr. Selz personally selected. You will be visited before and during production. In order to meet our demands, manufacturers must meet the strictest certificates and requirements in production.

Selection of raw materials
Our guiding principle is: Highest quality!
We always only use the highest quality available on the market. This is a guiding principle of every dietary supplement from Dr. Selz GmbH.

Organic if possible
Whenever possible, we use raw materials from controlled organic farming. You have to know that not all raw materials are available in organic quality or that the organic standards from abroad do not correspond to those in Germany. That's why every batch of raw materials is tested for pollutants, heavy metals and pesticides. Our raw material suppliers are just like the manufacturers

Product development
The product development is carried out by Dr. Selz carried out personally in collaboration with many specialists. We rely on a network of dietary supplement manufacturers that has been tried and tested for decades. Specialists include biologists, pharmacists, chemists, biochemists and laboratory assistants. The expensive product development sometimes takes up to over a year and is carried out by Dr. Selz personally carried out and supervised.

Marketability within the meaning of food law
Our products are checked by specialized lawyers for EU conformity and conformity in the sense of German food law. Expensive legal reviews are carried out for each of our products. While there are countless suppliers of nutritional supplements on the market, we differ significantly from other suppliers in this respect. We want to create maximum product safety for consumers. This process is costly, time-consuming and not required by law. However, we still see it as a matter of course for the product safety of our customers. We want to clearly distinguish ourselves from black sheep. In addition to product quality and purity, the safety and legal compliance of the products are very important to us.

Without unwanted additives
We work according to the principle of purity and do not use artificial flavors, release agents, colors and stabilizers. Whenever possible, our products are vegan, lactose-free, gluten-free and made without preservatives.

Our competence
Quality is no coincidence! Our product formulas are based on the specifications of Dr. Selz created and continuously improved with our network of experts.
Dr. Selz personally checks production and quality control directly at the manufacturers and through our partner laboratories.

Our goal
Your satisfaction! So that we can support you in your goal of optimal health maintenance and health promotion, we only supply nutritional supplements with the highest quality properties.
