    Yes, it’s EXACTLY the same product with a new name. No other changes. The new name took effect in July 2023.
  • What is the difference between a Prebiotic and a Probiotic? How will they support my gut health?

    Prebiotics are a specialised plant fibre that acts as food for the good bacteria. This stimulates growth among the pre-existing good bacteria. (Think of it as a fertiliser for the probiotics.) Probiotics are living strains of bacteria that add to the population of good bacteria in your digestive system.
  • Will your Gut Harmony Balance supplement help improve my gut health?

    Gut Harmony Balance will help support the growth of good gut bacteria and also make it harder for bad bacteria to flourish.
  • When is the best time of day to support my gut health by taking my probiotic supplement?

    Probiotics are usually most effective when they have been taken on an empty stomach to make sure the good bacteria makes it to the gut as quickly as possible. The best time to take a probiotic is either first thing in the morning before eating breakfast or before going to sleep at night. Also avoid taking them with hot drinks as the heat can be harmful to the delicate bacteria strains.
  • Will I be less bloated from taking your probiotic supplement Bioharmony Balance?

    Probiotic supplements can help improve the bacterial environment in the gut, which can help reduce symptoms of gas and bloating.
  • Is your prebiotic/probiotic gut health supplement suitable for vegans?

I just thought I’d contact you to let you know how much the Guy Harmony Balance are helping my mum. She is 74 and had 70% of her bowel removed 3 years ago after being diagnosed with stage 4 bowel cancer. She did not need to have a bag thank goodness. Then afterwards she had chemo for 6 months that got extended to 8 months due to complications. Since then she has been getting used to her new, shortened colon as well as trying to rebuild her strength and immunity after the chemo during covid etc. She has tried a few pre/probiotics but not really felt much relief until she tried Hello Day. After just 2 weeks she noticed a significant difference for many reasons. I just think that this information could be valuable to both other people in similar situations and Hello Day.

Did you miss me? I'm back! Back fro good too. I love this product but I stopped tacking it. It took me about 8 months to realise i should be taking it again. My tum tum feels much better when I take your tablets. I've learned my mistake, it won't happen again. pls forgive me.

Katie H. | 2023-06-06 12:10:36

I poop with absolute ease now! Before I was so bloated and gassy, I thought I would blow the toilet bowl apart. You know that explosive bloating feeling. (ka-Boom!) Now I have the most delicate poop sessions. It's an absolute joy.

Bianca | 2023-03-13 15:45:23

Maybe I'm taking the name of this product too literally, but I do feel like my gut is dancing to a better beat. I'm less gassy, less bloated. My gut has more harmony.

Melanie | 2023-02-02 10:52:29

An absolutely beautiful product. 'Harmony' is the right word for this product. Thx.

Louisa | 2022-07-27 12:14:27

Constant bloating was really getting me down. Besides making me feel unfortable, it was making me look chubbier which I've battled with for ages. This product has really helped reduce bloating. I'm starting to feel much better about myself now. Thanks for your help.

Eniga | 2022-05-30 16:02:33

Looks like people have no problem sharing in regards to this product, so I'm just gonna say it, it has me pooping like an excited young rabbit. Before I was blocked-up like an old cement truck.

Liz Rowe | 2022-05-25 16:05:31

Bio Harmony - what can I say! The best product I have ever used for my poorly tummy symptoms - I took religiously every day and noticed the difference in pain, bloat and ahem, the little troll that is gas living in your stomach! I can't recommend enough, on subscription they are highly affordable and just perfect alongside my seasonal boxes as a constant.

Jackie Hall | 2022-05-25 15:58:15

Where do I start? I came across your products through social media platform. It as their bright and colorful packaging that drew me to the company. I had a little read to see what the products here about. I'm not vegan but i do have certain intolerance so finding right supplements can be hard. I liked your website where i was able to take a quiz to identify which products would be more suitable for me. I was amazed by how many different products that they have on offer and that they target seasonal symptoms. i suffer with IBS so was interested in trying the Bio harmony that has probiotic in. Wow i am amazed, this certainly has improved my symptoms, less bloating, less feeling sluggish or unable to go to the toilet.... I could go on and on, I am no taking these on a daily basis and have subscribed to them. If you are in doubt, trust me give it a try you wont be disappointed and prices are reasonable too.

Ali Morton | 2022-05-24 14:04:44

Where would I be without Hello Day?.. Being someone who has an extremely sensitive stomach, gluten free and vegan I have found supplements such as Bioharmony Balance amazing. I can’t be without it. I start my day taking one and notice on the odd occasion I don’t have it. Bouts of IBS have almost gone and I feel happier all round as my body aka my gut is happy. I also have BB on monthly subscription so I am never without. It’s so easy. Thank you Hello Day.

Maz | 2022-05-12 10:05:37

Excellent product

Napalm Sally! | 2022-03-21 16:09:44

I took this product for nearly 3 years and I was relatively fart-fee. I skipped a few months, thinking I'm good now...well that was a mistake. I've become bomb-bastic with a rear assault on my whole family. My kids even asked me what was happening. Then I realised it was my own silly fault for stopping my subscription. I'm back on it (my kids are safe again) and I hope to fix the situation before my husband ditches me for a less flatulent model. I'm not in an attractive way at the moment. #HealthandSafetyHazzard

Bernice | 2022-01-05 16:30:47

I'm just going to say it, I fart a lot less when I'm taking this. So my husband likes it as much as me.

Ann-Marie | 2021-09-29 11:40:50

THis has been my fav product for nearly 1-2 years. The reduction it has made to my IBS symptoms is incredible. Basically, I'm less sensative, less bloated, less windy and less consipated. It has made me more confident with my gut. I used to feel like I was being held hostigae by my own digestion --Not anymore! So I would recommend this to anyone who knows what I'm talking about. Like you, I'm sure you'e tried everything. I can tell you, THIS WORKS.

Melissa Jessome | 2021-09-03 09:59:47

this product has saved my gut. not jokes folks. full love from me

jake | 2021-08-31 15:55:09

Look, amazing product but I'm disappointed you don't do a 3 month supply.

Maria Johnson | 2021-08-25 09:01:30

This is such a good probiotic.

Annick | 2021-08-16 11:07:42

L’effet ressenti de ce probiotique sur ma flore intestinale est impressionnant. En 5 jours seulement, mes douleurs dans le ventre ont disparu et je me sens libérée… je le recommande!

Melissa James | 2021-07-13 09:36:54

My gut was in absolute chaos before I tried this product. I have tried probiotics which did nothing and then others which were too strong for me (causing other unattractive issues). It sounds like I'm telling the story of the Three Bears, but this one has helped me so much.

Louisa | 2021-04-15 14:34:06

This probiotic has changed my relationship with my belly. Less bloating, gas, discomfort. You name it, its better.

Liz | 2021-03-23 10:13:35

I contacted your customer service about my farty husband a few weeks ago. Your response was hilarious... I did indeed open a window. I also got him this product and so far so good. But thats not to say I won't keep the window open. He's sneaky.... ;)

Tamara | 2021-03-09 17:46:27

Us IBS people always leave reviews because helpful products are hard to find. This product really helps.

Alice Marks | 2021-02-18 13:53:11

I have NEVER found a probiotic like this one. My bloating is completely gone now.

Alice | 2020-12-03 10:37:50

My favourite product!

Sarah Macfarlane | 2020-11-25 12:58:34

Still the best probiotic I've ever taken. I know this because when I stop, I see a difference within days. I'm hooked.

Pamela | 2020-08-25 08:51:00

This is really helping my gut issues. Especially my gluten problems. I feel less bloated for sure.

Jason | 2020-07-18 08:37:54

Best probiotic I've ever tried, but I would prefer a 3 month supply so I didn't have to order every month.

Lisa Blair | 2020-07-08 09:25:25

Years! I have tried different probiotics products for years. This one has made such an improvement. Thanks also for the education of bacterial cultures.

Abbie Sewell | 2020-07-01 15:53:26

I can certainly tell the difference when I'm NOT TAKING this product. I forgot how bloated I used to get. I thought my gut was fine after taking these for over a year. I realised I still need them. They really work. I"m much more comfortable. I think I'm a life with this probiotic.

Latifa | 2020-06-30 23:23:41

I bought these after a friend recommended them to me. I've been taking them for over three weeks and definitely notice a difference with my gut health. Even my husband noticed. I came here to purchase another box, so thought I'd leave a review for people that may be suffering with their tummy but are apprehensive about making the purchase.

Holly | 2020-06-21 14:30:35

This product has helped so much with my IBS! I've tried so many probiotic's but this on beats them all. Highly recommend!

Bonnie | 2020-06-02 14:39:20

What can I say, I'm less farty! Result

Doreen O'Keefe | 2020-05-26 10:47:56

I've been taking these for 18 months now. They really are a game changer. They really help with any IBS issues.

RR | 2020-01-29 19:38:16

I have been taking the HD probiotic for about 6 weeks now, this includes over Christmas, which is my most dreaded time of year due to the upheaval of my diet and in turn my digestive system. This product really helped to relieve stomach cramps over the holiday season, which I am really grateful for. I'm still new to the product, but happy with the results thus far.

Ed | 2019-12-16 12:59:21

My friend recommended this product. Really good. Now I've recommended it to other people. Really worth a try.

Vincent | 2019-12-16 12:57:59

This is my favourite, favourite, FAVOURITE product!!!!! I have tried so many probiotics to help with my IBS and I've not had much luck. This product is so good.... I could see improvements in about 2-3 weeks (Less bloating and wind), then I noticed some actual changes after about 3 months. (I could have a piece of regular toast every now and then without the awful consequences.) I'm so pleased with this product. Thanks also to your customer service team for taking the time to help me. Really good product.
