On Making Our Probiotics: Batch by Batch

We have been waiting for the Original and Cranberry Pomegranate Synbiotic formulas for a few months.

Probiotics and polyphenols are at the heart of BioImmersion! 

So I thought to write a more personal note and go over the process of making probiotics and what we do -- and do not do - to bring you some of the best, freshest, strongest, and most potent probiotics. 

I also would like to thank you from the bottom of my heart - Please know that I truly understand the frustration of waiting. The Original is arriving this week, and the Cran Pom soon after! 

Lets start with what we do not do:

To explain and show you why at times we have to wait for a while, I'll start with what we do not do.

We do not "buy in bulk" as many companies do, and do not have sealed bags of different probiotic organisms sit in a warehouse so we can mix them when we run out of certain formulas. Yes, it sounds efficient, however, it is also a fast way to lose potency. 

We also do not buy probiotics from the cheapest and fastest distribution companies that have materials sit on their warehouse floors. 

We also do not accept batches that are not the best in terms of quality, with lesser count or a certificate of analysis that shows some (minor) contaminations or allergens. Other companies may simply get that batch and save 10% to 30% off. Some contamination are not high enough to cause trouble, but we just don't like them. 

So what do we do?

What we do is actually GROW the probiotics, each time for each formula.

Sounds like a lot of work in our day and age when everything is bagged and ready to go, but to achieve the kind of synergy and potency, and to have the formula truly perform, we like to create each batch from scratch. 

What does it means to grow probiotics from scratch? The steps are actually quite simple. 

We have chosen with the help of our scientists probiotic strains that like to work together and achieve more as a community than separately. Like all organisms (and humans!), each probiotic has a like and dislike for other probiotic organisms and choosing the ones that work together well is important. 

Some probiotic organisms (or microbes) do very similar work - they perform similar tasks and are good at these tasks. Choosing the probiotics that can do similar tasks focuses a formula on certain results, like the Supernatant is designed as an anti-microbial. Choosing probiotics that perform different tasks means the formula is broad-spectrum, like the No 7 Systemic Booster - for longevity and anti-aging.

The 'growing' phase: Probiotics go through the fermentation process to grow and multiply. This means that feeding them the right foods and nutrients is important, like all organisms, they have preferences for certain foods. A misconception is that probiotics can only grow well on milk, but probiotic grow beautifully well on other non-dairy media. We prefer non-dairy for our probiotics. 

Once the probiotics are strong and ready, they are separated from the metabolite soup (the good stuff they excrete - we call it the Supernatant). They are freeze-dried separately and then mixed again for our BioImmersion formulas. Most often the metabolites are thrown away, and that is a waste (literally) as it has so many nutrients and it is a very effective immune booster. 

Throughout the process the microbes go through lab testing to ensure their optimal performance, and to check for allergens, pathogens etc. The final Certificate of Analysis (CofA) is analyzed to ensure the quality and potency is upheld.

As you can see much can go wrong during this process but much can be right and potent - which is exactly what BioImmersion focuses upon. 

Seann and I have always valued the highest quality, our aim has been to create not just good products, but excellent products because we know that when fresh, pure, and potent materials are pulled together, much can be done for health.

Thank you again for standing with us, and now with me, to produce and bring you only the best. 


Sincerely yours,
