    • On a spoon
    • In a bottle of formula milk or expressed breast milk
    • On a clean finger (one drop at a time)

    * Refrigerate if using dropper directly into the mouth. No refrigeration necessary when stored in a cool dry place below 25°C.

    For best results use daily.

    • Very satisfied! My 1yr old baby was extremely prematurely born, without any particular issues in the digestive system. I trusted a close friend of mine who is a nutritionist and recommended this as a high quality and researched product. Giving probiotics is the best I can do for supporting the digestion and absorption of nutrients, as well as the immune system of my preemie. Drops are easily given directly from the dropper and taste great! and this means that I do not necessarily have to mix them in milk, baby really loves them! Poopies smell and look normal, no adverse effects at all in almost one month use. I hope the product becomes available in Greece soon, so that I can avoid waiting for the delivery from UK which takes really long.

    • Ordering more! The results of our 1 year old taking this product for just one month are very noticeable! Farting - good improvement.. Very happy with these results. Great product, and the kiddo loves taking it as well, straight out of the dropper! It is now one of our daily rituals.

    • We had previously been using the powders one of my four year old twins. As a dairy free alternative these are great. The drops are much easier/quicker, and whilst he wasn’t too impressed with the taste directly on on his tongue he is quite happy to see them be mixed into his milk and cereals in the morning (to the point where he reminds me!) We have seen a vast improvement in his skin, but also noticeably in his toilet habits which is a encouraging with him due to start school in September. We’ve noticed that there have been less flare ups even with the warmer weather. Definitely worth the extra 30 seconds it takes to do a dose daily.
