Why should I take Optibac probiotics daily?

Due to modern lifestyle factors it is best to replenish our gut flora on an ongoing basis, and this is why many people choose to take their Optibac Probiotics daily.

We do not produce friendly bacteria ourselves, so it is important to think about ways of topping up and nourishing the probiotic bacteria in our guts regularly.

Probiotics reach the gut quickly but don't stay there for long1,2, instead passing through and exerting health benefits as it goes. Even a maximum strength friendly probiotic supplement such as Optibac Probiotics Every Day MAX constitutes just a tiny fraction of our microbiome, so is fine to take daily and long term.

There are some situations where certain strains are taken for a short time, such as when taking or recently finished taking antibiotics. 

In general though, probiotic supplements are best taken on an ongoing basis as part of a daily health regime. Find out more about taking probiotics daily, on the Probiotics Learning Lab.

Who should not take probiotics daily?

Probiotics are one of the safest natural supplements available. There are a few groups of people, however, who it is recommended do not take probiotics, unless under guidance from a doctor. 

This includes people with serious medical conditions, such as those 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.

Probiotics can be taken daily alongside all natural remedies without any problem. The only consideration is if a supplement has antibacterial or anti-fungal properties, in which case we recommend that you take the probiotic at least a couple of hours either side of the other supplement, so as not to damage the bacteria.
