Should I take probiotics in capsules, tablets, liquids, gummies or powders?

Probiotic supplements come in many different formats.Should you choose probiotic capsules, tablets, pills, or powders? Are gummies effective? Are liquid supplements better? Don't worry, if you buy your probiotic supplements from a trusted specialist company, all formats will be equally as effective, so just choose the format and strains which suit you best.

Find out more about choosing the best probiotic supplement.

Is it ok to take probiotic supplements every day?

Yes! It is both safe and recommended to take your favourite probiotic supplement on a daily, ongoing basis. Research7,8,9 suggests that probiotic bacteria only colonise in the gut for a few weeks, so it's a good idea to have a regular intake of live cultures.

Can I open probiotic capsules?

It's absolutely fine to open Optibac Probiotics capsules and take the contents directly into the mouth or in cool, non-acidic food/drink, without any effect on the viability of the friendly bacteria. Encapsulated live cultures from other brands may need to remain in their capsules, however, so best check with the manufacturer.

Do Optibac Probiotics sell friendly bacteria vitamin supplements?

We certainly do! We offer a range of probiotic supplements with added vitamins and minerals for both adults and children. You can choose products with added Vitamin C, Vitamin D, Vitamin B1, Calcium, and Zinc. For more information, visit our Added Nutrients section.
