FAQ

Narex products use the authentic Narine bacterium, first isolated by Professor Levon Erzinkyan in 1964, whose identity can be verified with the strain passport held by the Republican Microbe Deposit Center at the National Academy of Sciences of Armenia. Narex secured rights to this strain under a 1999 agreement, ensuring the authenticity of our products. Since then, we’ve offered lyophilized Narine probiotics as the first licensee of these bacterial cultures.

For children, sachets work best because they can easily dissolve in water or mix into food. Capsules are recommended for those aged 5 to 6 and up, as they are easier to swallow.

Yes – they’re considered safe. Narine is a naturally occurring probiotic that supports gut health and doesn’t have negative effects on the mother or child.

Products containing the Narine strain are generally very well tolerated and side effects are rare. As with any supplement, if you have doubts, consult your doctor and monitor how your body responds.

Keep them refrigerated at or below 8°C in a cool, dry place, away from direct sunlight, and out of reach of children.

In most cases, yes. Narex probiotics are generally safe to use alongside other medicines, but it’s best to consult your doctor, especially if you’re on strong or long-term prescriptions.

Yes. Narex probiotics can be part of your daily routine and typically don’t conflict with other supplements or over-the-counter medicines.

It depends on preference and convenience. Sachets are ideal for children and for anyone who finds swallowing capsules difficult, since they can be mixed with water or food. Capsules are a good pick for travel and for those comfortable taking pills.

You may see the first benefits within up to 15 days of regular use. In cases of pronounced dysbiosis, improvement can sometimes be felt as early as 1–2 days, as adding active bacterial cultures can bring quick relief by helping restore microbiome balance.

Narex probiotics are dietary supplements and are not intended to treat medical conditions. Research suggests that some probiotics can support the gut barrier and help modulate immune responses, which may ease symptoms for some people. Effects vary from person to person, so if you have diagnosed allergies or intolerances, talk to your doctor and don’t change prescribed treatment without medical advice.

Yes. You can combine Narex probiotics with at-home approaches like a fiber-rich diet and natural yogurt.

You can use Narex probiotics to make homemade yogurt, smoothies, or as an addition to salads. For inspiration, look at recipes for healthy breakfasts and snacks that include natural probiotics.

We chose Narex to produce our probiotics because of its more than 20 years on the market. Narex has earned recognition by consistently delivering high-quality products, which speaks to its reliability and effectiveness. Its long experience in the health sector has enabled the development of innovative technologies and production methods that ensure the highest levels of efficacy and safety.

Lyophilization, also known as freeze drying, is a preservation process in which the product is first frozen and then its water is removed by sublimation, meaning it goes straight from solid to gas. This puts the bacteria into a dormant state without damaging their structure or function, allowing for long-term storage without preservatives.

Lyophilization is convenient because it allows products to be stored at room temperature, making them easy to transport and keep. While fresh yogurt may be more effective thanks to live cultures, freeze-dried products offer greater stability and a longer shelf life, which helps preserve their effectiveness outside a controlled environment.

During freeze-drying, live bacteria are frozen and dehydrated, which puts them into a dormant state while preserving their structure and ability to reactivate when rehydrated. You can demonstrate their effectiveness not only with lab tests (which show growth and reproduction after rehydration) but also with a simple home experiment. Make a starter using Narex Sachets: add the sachet contents to milk and leave it in a warm place. If the bacteria are active, the milk will ferment properly. As a control, keep another portion of milk under the same conditions without Narine – it will not ferment and will remain unchanged. This is a practical way to confirm the viability of freeze-dried bacteria.

To prepare yogurt from a freeze-dried starter, mix the contents of the sachet containing the bacteria with the appropriate amount of milk, following the instructions on the package. Then incubate the mixture in a warm place to allow the bacteria to ferment the milk.

Reusing the same culture for many rounds can weaken it. With each re-inoculation the microbial balance can shift, wild microbes may creep in, and the bacteria can lose vigor. After about 4 to 5 cycles, you often see slower acidification, weaker texture and flavor, and lower viable counts. For consistent quality and benefits, start again with a fresh freeze-dried starter.
