Kale Brock describing how to pick the best live cultures supplement for you
On his recent trip to London he realised he needed a re-stock of his friendly bacteria and visited Whole Foods Market. In this video he goes through the key factors that are important to remember when deciding which live culture product is best.

Bifidobacteria & fibre - high in fibre

Kale's key factors to choose the best live culture supplement

1. Check the ingredients

A rule which you could apply to purchasing any supplement or food is to always check the ingredients, no matter what the product may say on the front. It's always good to see what, if anything, is added that ultimately doesn't need to be there, like colouring.

2. Different forms of friendly bacteria

The second factor to think about is what form you prefer the supplement to be in. There are many ways in which you can take live cultures (capsules, gels, tablets, sachets etc) and depending on your own personal preference, this may have an impact on which one is best for you. Sachets and capsules (which can also be opened) make it easy for the consumer to include friendly bacteria in cold drinks or sprinkled over morning cereal.

3. Get the right strain for you

Kale advocates the importance of identifying the best researched strains. To do this it is key to look at individual strain names instead of just the species. So instead of looking just for Bifidobacterium lactis, one should instead look for Bifidobacterium lactis BB-12® - a specific strain which has been extensively researched for a specific area. To find out more about specific strains and the research that supports them, take a look at the Probiotics Database, an impartial compilation of the world's most well-known strains of bacteria.

4. Added extras

In some cases, prebiotics such as FOS fibres are added to help feed and promote the growth of beneficial bacteria. This can help not only dramatically increase the number of live cultures, but help them to thrive in the gut.

5. Clinical Trials

High quality live culture supplements need to have been extensively researched and used in human clinical trials. For example, the Bifidobacterium lactis BB-12® strain has been featured in one of the world's largest ever clinical trials.


It was due to this clinical trial that Kale felt confident to use OptiBac 'Bifidobacteria & fibre'. This sachet product contains 5 billion CFUs of live cultures and also includes 4g of FOS fibres in each sachet. Thanks to the high amount of natural fibre in this supplement, it is often chosen by those looking to increase the amount of fibre in their diet.
