Travel with Optibac
I was recommended Optibac by a friend for my travels around India. I was ill twice in Thailand 6 months before and I was keen not to go through that again in India.
Optibac Travel was brilliant and I was never ill. Now I'm home, I'm using Optibac Everyday.

Fantastic company
I came across Optibac whist looking into probiotics online. I visited their site and there was an option to book a telephone appointment with a nutritionist which I did. A lovely lady rang me and I discussed the issues I was having and she recommended two different types of probiotics, Optibac for women and Optibac extra. She explained how they worked and gave me so much information regarding my issues. When we had finished, she sent everything we had discussed to me in an email with so much useful information. I take the probiotics every day and they have significantly improved my issues. I can't recommend them enough. Also with so many counterfeits on selling platforms, I feel safe in the knowledge that the probiotics are the real thing. I highly recommend Optibac.

This was the second product that I have tried for my stomach issue. This probiotic made me feel a lot better than the first one that I’ve tried from a different company! Constipation wasn’t a big problem with this probiotic and my stomach felt a lot better. This was suggested to me by one of your ex employees Seher :) Thanks to her.

Optibac are the best!
As a company they make it easy to find a supplement to match a problem. They are very caring and able to offer advice if needed too. When you have made your selection they are also very good at communication as well as delivering on the right day.
The Women's Wellbeing supplement works well for me, even better than the Everyday probiotics I used to have from Optibac. I feel balanced and less "thrown" by stressful situations, which is so helpful as I am anxious by nature. I did worry initially that bloating might reappear but so far it hasn't ( and that's a good few months now).

This is the best money I spend every month.
I’ve been using optibac for my children for around a year now, I had started as a last ditched attempt to try and help my toddler that was endlessly unwell. After starting nursery we were not going more than a week before the next illness hit and it was relentless. Someone had recommended trying probiotics so after doing some research I found optibac and gave them a try. Since starting the change has been astronomical. Both my children have suffered very little with any kind of illness at all. I recommend them to absolutely everyone, especially those with young children in a childcare setting. Whether it a coincidence or not, I cannot say but there’s no way I’d stop to find out just in case. The delivery is great, never had an issue with any of the products and the subscription is easy to manage.
