    How do I choose the best adult gummies?

    Choose probiotic gummies with natural ingredients and no added sugar, containing highly researched1,2 strains, such as Bacillus coagulans Unique IS-2, which has been shown to support gut and immune health*. You can find this strain in our delicious Optibac Probiotics Adult Gummies, which are also vegan, dairy, and gluten-free, so they're suitable for everyone!

    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. These friendly bacteria and multivitamin gummies don’t require refrigeration and can be taken with or without food 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 vitamin D gummies each day. It’s not possible to overdose on probiotic supplements (your gut naturally contains trillions of friendly bacteria!) but for the added vitamins it’s best to stick to our guidelines and keep an eye on your daily intake3, especially if you take several different vitamin and mineral supplements each day. 

    What is the difference between gummies vs capsules or powder?

    Probiotic supplements in capsules or powders typically contain Lactobacilli or Bifidobacteria, whereas gut gummies use heat-resistant friendly bacteria like Bacillus coagulans Unique IS-24,5. Because they taste like yummy ‘sweets’, people often wonder if probiotic gummies are as good as capsules or powders, but if you buy from a trusted company, you can be sure the ingredients and probiotic strains are of the highest quality, and every bit as good as other formats. 

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

    Optibac Adult Gummies are completely natural live cultures supplements with no added sugar. At less than 8 calories each, you can easily make room for them in any calorie-controlled diet, safe in the knowledge that every gummy is bursting with healthy goodness!


    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.

    • Through a routine scan for problem with my hip I was unexpectedly diagnosed with diverticulitis. Despite it being mild to moderate it was beginning to impact on my lifestyle. I had spells of bloating,chronic indigestion,discomfort and my stomach constantly rumbled and grumbled. I had always taken Optibac immune probiotics but decided to contact the team direct to ask for some advice. Their swift and informative reply steered me towards the Adult Gummies probiotic. What a revelation, within 2 weeks I felt so much better ,and all my unpleasant symptoms have disappeared. Optibac care about their customers as much as they do about making a great range of products. I thank them wholeheartedly for being so fantastic.

    • These taste absolutely incredible, almost as good as Percy Pigs minus all the sugar! As a vegetarian it’s rare to find gummies that are gelatin free and have no added sugars. The fact they are so yum and easy to take means I take one every day, before I struggled with capsules and pills always forgetting to take them daily. Since taking them I have more energy and feel healthier. High fives to everyone at Optibac for creating a mega tasty vegan probiotic!

      Ben - 6th September 2022

    • 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.
