    Customer Questions

    All questions answered by probiotic experts Dr Kate Stephens PhD (Food and Microbial Sciences) BSc(Hons) Medical Microbiology and Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    How do I choose the best adult gummies?

    Gummies supplements should be made from natural ingredients, with no artificial ingredients or excess sugars. Probiotic gummies should contain a highly researched strain of friendly bacteria which is able to withstand the heat required to manufacture gummy supplements. Optibac Probiotics Adult Gummies contains Bacillus coagulans Unique IS-2, a highly researched strain of Bacillus featured in multiple gold-standard clinical trials 1,2 and shown to support gut and immune health*. These all-natural vegan gummies are made with real fruit purees and absolutely no artificial sweeteners, or flavours. They are also free from gluten and dairy. Oh, and they taste absolutely delicious!

    How and when should I take friendly bacteria gummies? 

    The great news is that you can take Optibac Probiotics Adult Gummies whenever it suits you. They don’t require refrigeration and can be taken with or without food. With a combination of probiotics, prebiotics, calcium, zinc, and vitamin D3, you can take these multivitamin gummies whenever you want to support digestion and immune health*, or better still, daily on an ongoing basis. Taking probiotic supplements has never been easier!

    How many Adult Gummies should I take?  

    We recommend taking one of our Adult Gummies per day, but as they’re so yummy you may be tempted to take more!  If you do sneak an extra gummy occasionally, don’t worry - it’s not thought to be possible to ‘overdose’ on friendly bacteria and the added ingredients vitamin D, zinc, and calcium have safe upper limits much higher than the levels included in our Adult Gummies vitamins3. But it’s best to stick to our recommended daily amount, especially if you take several different vitamin and mineral supplements, and keep an eye on your daily vitamin and mineral supplement intake. Our team of nutritional therapists are always on hand to advise if you have any concerns.

    What is the difference between gummies vs capsules or powder?

    Because they taste like yummy ‘sweets’, people often wonder if gummies are as good as capsules or powders. But if you purchase high-quality supplements from a trusted company, then all formats should be of equal quality, so it’s really down to personal preference which you choose.

    In terms of ingredients, capsules and powder products usually contain strains of Lactobacilli or Bifidobacteria, but gummy supplements are heated during manufacture so it’s important that they contain strains which are more resilient to moisture, acid, and heat4,5, like the highly researched Bacillus coagulans Unique IS-2 in Optibac Probiotics Adult Gummies. 

    Our high-quality Adult Gummies supplement is designed for all-round digestive and immune support*; however, if you have a particular health condition, you may also like to consider a supplement containing probiotic strains which have been researched for that particular condition.

    Can I take gummies if I am on a weight loss diet?

    When you’re counting every calorie, it’s important to make sure that every calorie counts. Optibac Probiotics Adult Gummies are completely natural and they’re bursting with friendly bacteria, fruit, vitamins, and prebiotics (FOS). At less than 8 calories each, you can easily make room for them in any calorie-controlled diet, safe in the knowledge that they contain less than a third of a teaspoon of natural fruit sugar, and that every little bit is healthy! So, whether you’re trying to lose weight, tone up, or gain weight, they’re a very positive addition to anyone’s diet.


    Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

    This is a dietary supplement and is not intended to prevent, treat or diagnose any medical conditions. Probiotic supplements should not be used as a substitute for a healthy lifestyle and varied diet. If you are pregnant or breastfeeding, taking any medications or have a serious medical condition, consult a doctor before use. Optibac supplements will not cause dependency and may be used on an ongoing basis.

    • Really fruity taste and apart from the friendly bacteria they contain vit D and zinc so saves me buying any extra tablets. Started taking half a gummie to ease my way on to them, now stomach issues have resolved themselves. Really really pleased.

      Wendy - 23rd May 2022

    • Fantastic gummies, very tasty and easy to take. Ideal for me, as I am having problem with swallowing bigger pills, I have calcium growth on thyroid that might cause this issue. I trust that ingredients are top quality and easily absorbed by our body. I wish all my vitamins are gummies, thank you Nadia for recommending it to me. I understand that the company is ecologically orientationed, it is always a plus.

      Alicja L - 1st April 2022

    • These are delicious! Really nice flavour and texture, feels like a little treat every morning even though they're a vitamin/probiotic supplement. And so much easier than having to swallow a massive tablet! Thank you Kerry for the recommendation, I'm paying it forward and recommending them to anyone reading this.
