Contains FODMAPs, so not for everyone

This contains FOS, which is a FODMAP and can agravate symptoms for many people with IBS. In other words, for some, it can have the opposite effect to what the product's name suggests! Optibac's website states the quantity of FOS in this product is too low to aggravate most people. Sadly, this was not the case for me! Although these perhaps made me a little more regular, they also made me super bloated, so I didn't even make it to seven days. Should have known better and not wasted my money. I think Optibac do make some good quality probiotics, but the name of this product is somewhat OTT and misleading, as it won't help everyone.

I was really feeling good just a couple of days into taking these. Good value for money in my opinion. Made a real difference.

I bought this as I would not be able to get Kefir whilst I was travelling. No bad effects, but no evident positive effects either - won't bother taking this with me next time. Did not replace the benefits of Kefir on my digestion.

Surprised at how well and how quickly this worked

Received this as a sample, and didn't expect results as it was relatively close to expiry. However, it sorted out a disturbed gut within a couple of days. Will buy again

Good variety of bacteria

Recently took a course of antibiotics so was glad to try this. Hard to tell if it works (yet) but certainly is easy to take, better variety than some other probiotic foods, and no bad reaction at all.

Trusted brand

With 5 billion Bacteria per dose and a blend designed to reach the gut alive, this is the product I turn to after any course of antibiotics.
