What's the Strongest Probiotic on the Market?

What's the Strongest Probiotic on the Market?

Questions abound about probiotics: which source is best? Which species provide the most benefit? Are synbiotics more important? How much good bacteria is enough?

One of the most common queries made by people searching for a probiotic supplement is, what’s the strongest on the market?

Perhaps these people appreciate that a high-strength product is needed to exert the desired effects.

In any case, this article provides information about the strongest probiotic supplement currently available.

Progurt: The World’s Strongest Probiotic

The most powerful probiotic currently on sale is Progurt, created by the International Probiotics Institute based in Australia.

Unlike most probiotics which exist as capsules, Progurt comes in sachet form; just disperse in pure, non-fluoridated water, stir and drink. You can also use it to make your own probiotic yogurt.

As for the six million dollar question, exactly how potent is Progurt? You’ll find the answer on every palm-sized box of Progurt sachets: 1 trillion Colony-Forming Units.

Progurt is the only supplement which offers a 1 trillion megadose per serving. Most supplements offer between 1-30 billion active cultures per tablet/capsule, although there are a handful of supplements which do provide between 100 and 500 billion CFU.

The supplement market has grown in size in recent years, so there is still plenty of misinformation out there concerning probiotics.

For example, we have found examples of products marketed as ‘mega-potency’ or ‘super-strength’ which contain just two or three billion active cultures.

In no way could such a dosage be described as high-strength. As humans, our native microbiomes are teeming with trillions of native bacteria: in fact, we are home to approximately 39 trillion bacterial cells and 30 trillion human cells.

Introducing a few billion active cultures into such a frenzied, competitive environment is not likely to produce meaningful, long-lasting results. A glass of water spilled into the ocean does not, after all, generate a wave!

Although there are no hard and fast rules about what constitutes a strong probiotic, given the resistance which meets bacteria introduced to the digestive system a figure of 100 billion + seems more accurate.

Back to Progurt, then. Progurt is unique for a number of reasons. Not only is it the highest strength probiotic on the market, and available as sachets rather than capsules, but it also contains bacteria which is entirely human-derived.

In other words, the live cultures in Progurt were isolated and cultured from native human bacteria. This is quite atypical, since the vast majority of manufacturers obtain their strains from cows or soil.

The reasoning is simple: native human bacteria is much more likely to replicate/colonise than bacteria more attuned to other environments.

The native intestinal strains included in Progurt work synergistically and include:

Lactobacillus Acidophilus

Lactobacillus Bifidus

S. Thermophilus

Whether you’re considering taking a probiotic for general digestive health, immunity, antibiotic recovery, IBS relief, dysbiosis or some other reason, Progurt’s intuitive strains make it the perfect choice – even setting aside the therapeutic dosage and unique delivery system.

Importantly, the aforementioned bacterial strains are the ones commonly fragile or missing due to a combination of Caesarian birth, antibiotic exposure and the typical Western diet and lifestyle.

Why We Recommend Progurt

It is not only a question of potency. We recommend Progurt because its strains naturally support the growth and proliferation of other innate beneficial bacteria.

Of course, that is not to say you might not enjoy some transient benefit from another quality supplement.

We would, for the most part, advise against single-strain probiotics. Human beings harbour upwards of 500 probiotic strains in the body, so flooding our system with a single strain has the potential to create an unwanted imbalance.

It is vital to use synergistic strains which work together.

Truth be told, there is still a lot to learn about gut health: the research area is continually expanding, and is certainly more complicated than first supposed.

We have attempted to make sense of the research in two long-form articles on the subject: How to Restore Gut Health by Nourishing Your Microbiome and 3 Factors You Must Consider When Trying to Improve Gut Health. Although the microbiome is a complex topic, we have endeavoured to communicate the information in a way which can be easily understood by the layperson.


Progurt’s intuitive strains make it the perfect choice – even setting aside the therapeutic dosage and unique delivery system.

Whether you use Progurt or another product, it is wise to regulate lifestyle factors (emotional stress, medication, alcohol consumption, sleeping habits etc) if you want to positively influence your microbiome. These are all factors which affect probiotic colonisation.

Remember that ‘gut feeling’ is much more than a stock phrase: it describes a complex mind-gut connection deeply rooted in reality and keenly perceived by each of us. Trust your gut and make the changes necessary to enjoy better health.
