Excellent Probiotic for Gut and Stomach Health
I’ve been using BioGaia Gastrus and it’s one of the best probiotics I’ve tried. The chewable tablets are convenient and taste pleasant, making them easy to take every day. Since starting, I’ve noticed much better digestion, reduced bloating, and overall gut comfort. It feels gentle but very effective, and I like that it uses well-researched probiotic strains. If you’re looking for a reliable probiotic to support gut and stomach health, this is a fantastic choice. Highly recommended!

Helped tooth infection
This is amazing for tooth infection, I chewed it on the tooth and the pain and abscess swelling went away. I have a root canal that needs redoing as I can't afford dentist and no NHS I've had no choice but to suffer it, this is keeping infection at bay. I didn't buy it for this reason only realised afterwards that it sorted that issue out

Positive changes after a few weeks
After a few weeks, I felt more energetic, in a better mood, and experienced easier digestion. Excellent quality! The seller had great communication, was very understanding.

They worked for me
Bought them because I had an antibiotic treatment for stomach infection and doctor said to get probiotic supplements. Improved my digestion greatly, had normal stool taking these on daily basis. What I am surprised about is that while normally probiotics come in capsules, these are chewables and mandarin flavoured. The only cons is that the price is a bit high for only 30 in a pack, so no 5 stars, but I give a strong 4.

Appears to contain no live bacteria
Bought these to make L. Reuteri yogurt which I've made countless times before with other brands of probiotic. These ones did not work. After 36hrs in my yogurt maker the milk was still just milk, no yogurt at all. I conclude from this that these tablets contain no live bacteria and I've just wasted £25. It seems plenty of others have also had this issue. Considering how expensive the BioGaia brand is, this is very disappointing.
