Frequently asked questions about OMNi-BiOTiC® products

Most of the time, it is a good idea to take probiotics to help maintain a healthy gut and the wellbeing of your entire body. The gut is the engine of your life; it provides fuel by digestion and influences many other vital processes within the body (i.e. the immune system, liver function and detox pathways, and stress management). 

Today’s lifestyle makes it difficult to keep the gut healthy with the oversupply of processed foods, and harmful environmental, physical and psychological impacts. Probiotics ensure that good bacteria are replenished in the gut in order to strengthen the intestinal lining, and maintain a strong digestive system and overall organism. 

OMNi-BiOTiC® probiotics are uniquely designed to support different critical processes within the body. Take a look at our Product Fit Chart on our homepage to find best probiotic that best supports your body’s needs.

OMNi-BiOTiC® products are developed by Institut AllergoSan in accordance with quality criteria of the World Health Organization (WHO), the U.S. Food and Drug Administration (FDA), the World Gastroenterology Organization (WGO), and the Austrian/German Societies for Probiotic Medicine (OePROM / DePROM). All OMNi-BiOTiC® products have FDA GRAS (Generally Recognized As Safe) status and meet the quality criteria for medically relevant pro and synbiotics.

OMNi-BiOTiC® was developed by Institut AllergoSan in Graz, Austria. Institut AllergoSan was founded in 1991 and launched its first probiotic supplement in 1993. Over the last 25 years, Institut AllergoSan has become an internationally recognized center for research and formulation of natural products that support the wellbeing of the body by strengthening the gut. 

The OMNi-BiOTiC® product line is the #1 probiotic brand in Europe. Now, OMNi-BiOTiC® is also available in the U.S.

Institut AllergoSan’s expert Research and Development team first performs lab tests on each strain of bacteria for how effective it is in achieving a specific health outcome (e.g. reducing the amount of a specific potentially harmful bacteria in your gut that could cause digestive upset). The team then tests the combination of strains of probiotic bacteria that is included in one OMNi-BiOTiC® product via clinical studies on people to make sure it works well together to achieve the desired outcome.

Institut AllergoSan in partnership with leading research institutions and universities continuously performs placebo controlled, double-blinded studies to test and demonstrate the clinical efficacy of OMNi-BiOTiC® multi-species probiotics. In 2009, the World Gastroenterology Organization (WGO) acclaimed a study about OMNi-BiOTiC® AB 10 (Koning 2007) as one of the 12 best studies in the world. For more information about studies on OMNi-BiOTiC®, please refer to our Clinical Studies/OMNi-BiOTiC® Studies website section.

The human intestine contains more than 500 different bacterial strains. A mono-species probiotic preparation contains only one single bacterial strain, whereas the multi-species probiotic preparations of OMNi-BiOTiC® contain up to as many as eleven compatible, mutually reinforcing strains. Specific combinations of bacterial strains have been scientifically shown to be especially helpful when faced with particular health challenges.

The freeze-dried powder form of OMNi-BiOTiC® products protect the bacteria during transport and ensure that they are alive and strong when you receive the product. By reactivating the bacteria in water, it is ensured that the probiotics can navigate past your stomach, which is too acidic for the bacteria, and reach your intestine, where they will be most effective. Taking a probiotic capsule eliminates the critical step of bacterial reactivation in water for optimal strength.

Yes. OMNi-BiOTiC® products are certified vegan, lactose, gluten and soy-free, as well as Non-GMO.

OMNi-BiOTiC® probiotics are vegan, lactose-free, gluten-free, soy-free and nut-free. The probiotic powder contains different dietary fibers that serve as food for the natural, good bacteria, such as fructo-oligosaccharides and inulin. This is the food for intestinal bacteria. They are present in OMNi-BiOTiC® products only in minimal amounts, much less than is used in the clinical breath test to provoke a measurable reaction. If you extend the activation time of OMNi-BiOTiC® to 30 minutes, the bacteria almost completely metabolize their food so that, at most, only a few molecules of these substances enter your body.

For all OMNi-BiOTiC® products, only strains of bacteria are used that cannot produce histamine themselves, so OMNi-BiOTiC® products can be safely taken by people with a histamine intolerance.

Yes. OMNi-BiOTiC® products contain only strains of bacteria that naturally occur in the human intestine, and no chemical agents that can interact with other supplements or medications.

Depending on the health of your intestinal microbiome, this may be the case. If you are experiencing severe intestinal discomfort, it is recommended that you introduce and increase your daily dose slowly over a period of several weeks (beginning with the amount of a knife-tip) to prevent possible digestive side effects. Such situations are rare and only occur in about 5% of users.

Yes. You can easily take one OMNi-BiOTiC® in the morning and a different one in the evening. Different OMNi-BiOTiC® products should not be dissolved in the same liquid at the same time because each bacterial combination is exactly matched and supplemented with their special food in the form of a matrix.

The freeze-dried powder of OMNi-BiOTiC® products contains different dietary fibers that serve as food for the natural, good bacteria. This is the food for intestinal bacteria. 

If you extend the activation time of OMNi-BiOTiC® to 30 minutes, the bacteria almost completely metabolize their food so that, at most, only a few molecules of these substances enter your body.

Stir one sachet of OMNi-BiOTiC® once or twice daily into approx. 4 oz. / 125 mL of room temperature water, wait for at least one minute (reactivation time), then stir again before drinking. OMNi-BiOTiC® intake is recommended on an empty stomach, if possible (e.g. before breakfast and/or before dinner or bedtime).

OMNi-BiOTiC® probiotics are manufactured in the form of freeze-dried bacteria that need to be reactivated before intake. Due to its basic pH value, room temperature water creates the optimal environment to activate the bacteria and to energize them for their journey through your gastro-intestinal system. If you prefer, milk and milk alternatives, yogurt and yogurt alternatives, as well as tea are also well suited to rehydrate OMNi-BiOTiC®. Please note in general that the liquid in which you dissolve OMNi-BiOTiC®, should be under 100 degrees Fahrenheit, non-acidic. If the liquid is too cold, the bacteria cannot sufficiently “wake up” from their freeze-dried state. If the liquid is too hot, then they will die before you drink them. Juices and coffee are too acidic for the probiotic bacteria to survive.

The human body is made up of at least equal the amount of bacteria as cells. There are many different kinds of bacteria. Some bacteria are harmful, like pathogens. The majority of bacteria in our body are responsible for keeping us alive (e.g. modulating the immune system, defending the body against pathogens). The World Health Organization (WHO) defines probiotics as “live micororganisms, which when administered in adequate amounts, confer a health benefit on the host.” Probiotics are the good bacteria that naturally occur in a healthy gut. These good bacteria colonize the lining of the digestive system and ensure that the gut flora can perform its role in vital functions in the body (e.g. food digestion and nutrient absorption, the immune system, liver function and detoxification, stress management).
