The careful selection of raw materials ensures high quality:

The raw materials for Burgerstein products are selected with the greatest care. Only quality-tested ingredients in pharmacopoeia quality or equivalent ingredients are used. In addition, care is taken to ensure that substances are used which occur naturally in the body or in food and can therefore be optimally absorbed by the body.

The main focus is on: 

• high purity and physiology
• high bioavailability (usability) of the active ingredients used
• maximum tolerability
• hypoallergenic
• orthomolecular quality, i.e. only substances are used that occur naturally in the body or in food and are necessary or beneficial for health.
• careful selection of secondary plant substances and plant extracts used, which have already been successfully used in studies.
• pharmacopoeia quality or equivalent
• testing for heavy metals, environmental toxins, solvents, or other possible manufacturing-related contaminants.
• environmentally sound cultivation and degradation
• sustainability (e.g. fish oils)
• testing for the presence of genetically modified organisms
• human dignity (cultivation, trade)
