Within 24 hours they’ve made a huge difference. New high protein diet was wreaking havoc with my digestion. So grateful I found them!

Really good product I was having some problems when my Dr suggested these and they have been perfect, thank you.

Great customer care

Really informative website with an exceptional choice of probiotics to suit all. Easy to order. Great prices. Fast delivery. And they give to a worthwhile charity too. I'm looking forward to seeing how I feel after a month of taking them.

Easy to order, and dleivered on time. Advisor answerd my questions

Just dealing with a well established company who sell well researched products that are effective. Also who put their customer first, even when they have their own temporary difficulties technically

Great family run business, very reliable, reasonably priced and a really good product that works well for me.

I’ve used optibac products for a long time. Always great service and prompt delivery. Love the subscription option so I’m never without.

This was my second order as I was pleased with the results of the first lot. Very good service and good price.

Been using these for a long time. They were recommended by a dietician after I had some problems. They have really helped and I would highly recommend the brand to anyone. I trust the ingredients in them.
