What are probiotics?

If you're new to the world of probiotics, also known as friendly bacteria or live cultures, it can be very confusing. In simple terms, we all play host to trillions of tiny micro-organisms, most of which reside in our gut. Some of these are friendly towards their host, and some are not! It's normal to have a mix of good and bad bacteria in the gut microbiome, but an ideal balance is to have more good than bad. Modern living can affect this delicate balance, which is why many people take live cultures supplements containing friendly probiotic bacteria to help complement the natural gut microbiome. If you would like to find out more about good bacteria, head over to the Probiotics Learning Lab.
 

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.

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. Research12,13,14 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.
