The gut does more than you think

Did you know there are more bacteria in our gut than stars in the galaxy?

Also, 70% of our immune system is found in the gut¹. And get this, 90% of serotonin – the happy hormone – is made in the… yes, you’ve guessed it, our gut.

Here’s the thing: Everyday life works against your gut. Things like stress, travel, antibiotics, poor sleep and alcohol all throw things off balance.

At Optibac, we know how important the microbiome is – it’s the reason why we’ve spent over 20 years formulating friendly bacteria supplements that make it easy to give yours the consistency it deserves.

If you too get the importance of your gut, there’s no better time to get Optibac.

Why fermented foods can’t do everything

You’ve probably heard you can get enough friendly bacteria through foods like kefir and live yoghurt. So, why take a supplement as well?

Fermented foods like yoghurt, kefir and kombucha are on the rise. If you’ve already made them a part of your routine, great! They definitely hold their place in a healthy, balanced diet. However, the levels of live bacteria in these foods can be low or inconsistent.

Our friendly bacteria supplements are different. They’re specifically formulated to reach the gut with a guaranteed billions count.

When you consider the quality of the strains used, and the billions per capsule, Optibac actually offers incredible value for money!

Most people don’t know that the research behind the strains is so much more important than a higher billion count per capsule.
