Product is good. Delivery company Evri is awful.

IBS improvement
Bought on offer - arrived quickly. I suffer from IBS - I've now been taking Alflorex for a week & already have a big improvement in my symptoms - if the improvement continues I will definitely continue taking them.

Excellent service
First time trying probiotics from PrecisionBiotics and so far very impressed. Website easy to navigate and product arrived well packaged and on time. Notifications kept me updated though these were duplicated sometimes. Only just started taking the probiotics so can’t review their effect at the moment but I’m hopeful. Would use again.

Alforex is a life saver
Alforex is a life saver. After my gut being destroyed by series of antibiotics my daily intake of Alforex has enabled me to recover. PrecisionBiotics is reliable and supportive - and now part of my daily life!

Brilliant Product
I've been using Alflorex Dual Action for a month now and it’s been a game-changer. My digestion feels more settled, less bloating, and I just feel better day to day. Brilliant product - can't recommend it enough

Zenflore is tip top!!
I've been taking Zenflore for a month and genuinely can’t believe how good it is. I'm sleeping better and feel more focused during the day. These little capsules are brilliant — they've made such a difference. Truly impressed with the results.

I have been using Alflorex for…6 months
I have been using Alflorex for approximately 6 months now and I am thrilled with the results! After suffering for years with bloating and constipation, I now have a happy gut. I have regular bowel movements and no longer feel constantly full and sluggish.
Absolute game changer for me.

Efficacy.
Great experience. I'm on the 4th day and so far so good. Slept all night last night for the first time in ages and they do appear to have calmed my bloating down. Given it 4 stars as still early days yet.
