  • 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!

  • 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.

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 intake(1), especially if you take several different vitamin and mineral supplements each day.

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 (1,2). 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.
