Quality Criteria of Medically Relevant Probiotics & Synbiotics

according to WHO, WGO, FDA, and OePROM standards

Home - About Us - Research & Development - OMNi-BiOTiC® Quality Criteria


OMNi-BiOTiC® products meet the following quality criteria and consist exclusively of bacterial cultures that occur naturally in human intestines.

1. Safety

All bacterial strains used must have GRAS status, QPS status or comparable safety standards, which indicates the highest safety standard for human ingestion and the absence of side effects even with long-term use.

2. Number of bacteria (CFUs)

Our products contain at least 109 CFU/g (= 1 billion bacteria per gram of powder). This means that a relevant number of viable bacteria are ingested.

3. Activity

Probiotic bacteria are most effective during the first 24 hours after they have been rehydrated, as this is when they become active. In yoghurt production, bacterial activation takes place in the dairy, where yoghurt is made by producing lactic acid from milk. In powder form, this activation process occurs in our bodies, where the bacteria can actively get to work.

4. Reproductive rate

Proven reproduction of probiotic bacteria even after finishing the course of an OMNi-BiOTiC® product. Evidence of this has only been obtained for very few products until now, as only very high reproduction figures can be recorded. Evidence of this reproduction rate in OMNi-BiOTiC® PANDA, OMNi-BiOTiC® 10 AAD and OMNi-BiOTiC® STRESS Repair has been recorded and published in scientific journals.

5. Resistance to stomach and bile acid

The bacteria’s resistance to strong acids is an essential factor. The revitalisation of the freeze-dried bacteria should ideally take place outside the body in a neutral liquid, such as in a glass of water. There the bacteria absorb some food and gain strength before embarking on a journey through the stomach acid and through the intestines with bile acid and pancreatic juice.

6. Stability at room temperature

The number of bacteria present upon the expiry date is given, not the number of bacteria at the time of packaging. This is because many bacteria may already die after a few days if the environment does not meet the ideal conditions for survival. Upon request, a quality analysis of every OMNi-BiOTiC® product batch can be provided including evidence of stability at room temperature for 24 months.

7. Milieu optimisation

The ideal pH value in the small intestine is between 4.0 – 5.0. This environment is optimal for the reproduction of beneficial bacterial, however, not ideal for pathogens.

8. Multi-species formula of symbiotic bacterial strains

Scientific evidence suggests that the targeted combination of several bacterial strains is superior to the administration of a single strain for a variety of applications. The potential of the individual strains can be further increased through optimised combinations in multispecies formulations.

9. Synergy of bacterial strains

Not all bacterial strains get along well and they can also compete (e.g. for food), so the synergy of mixed bacterial preparations must be proven by a so-called “cross streak” method, or studies on efficacy should be available.

10. Free from sugar, gluten and animal protein

To avoid promoting existing intolerances.

11. Matrix

The bacterial reproductive rate and activity can be increased by adding enzymes, fibre, and minerals to the product’s composition. The mucus production of the intestinal lining is increased as well as the adhesion of the bacteria which has been ingested.

12. Studies on effectiveness

The effectiveness of probiotics should be proved through scientific studies on humans.
