How to Find the Best Probiotics

There are around 100 trillion bacteria in your gut which help your body function in a wide variety of beneficial ways — from helping to produce enzymes to synthesizing hormones and vitamins. These bacteria feed on insoluble fiber which helps good bacteria thrive in the body while pushing out less favorable strains of bacteria. It’s therefore important to look after your gut bacteria so they can look after you.

Here at Puori we often receive questions about how to find the best probbiotics. Let’s take a quick look and answer some of the most commonly asked questions about probiotics including why we formulated SB3 the way we did.

Finding the Best Probiotics


As the gut has a huge number of different bacterial strains, the more strains in your supplement the better, right? Well, not necessarily. Gut bacteria are living organisms which compete with each other for survival. Having a huge number of different strains in one supplement carries uncertainties because it’s difficult to establish whether all of the strains will survive (either in the packaging or in the gut). Different strains have been discovered to have different functions in the gut — from reducing constipation to weight loss.

Puori SB3 contains two strains of beneficial bacteria. They were chosen based on their scientific merit and extensive documentation. BB-12® and PCC® have shown to be beneficial in numerous experiments. In fact, Bifidobacterium BB-12® has been tested in more than 300 scientific studies. More than 130 of these have been human clinical trials. Some of the reported benefits include boosting immune response (1), reducing the risk of respiratory tract infections (2), and reducing skin irritation (3).

Likewise, Lactobacillus fermentum PCC® was awarded the Health Ingredient Excellence Award for its outstanding properties compared to other bacterial strains.

Liquid Versus Dried Probiotics

Liquid probiotic products mostly contain live bacteria, which superficially might seem like a good idea — you want live bacteria to reach your gut, after all. However, these liquid products not only contain live bacteria but also a source of nutrition for the bacteria which can lead to problems with stability and shelf life. The bacteria in the liquid only have a finite amount of food to keep them going strong. When the food runs out, the bacteria die, rendering the product useless. An additional problem with live liquid probiotics is the taste. The taste of live bacteria is not always great.

Additionally, as these bacteria are living inside a growth medium they are competing for food and space. Thus it is very difficult to create a live probiotic product which contains multiple strains.

On the other hand, there are dry products. These come in many shapes, sizes and forms. In essence, in dry probiotics all water is removed without damaging the delicate structure of the bacterial organism. The bacteria then live in a state of suspended animation, which creates a product which is very shelf-stable.

When the bacteria are exposed to a liquid, for example by mixing with water or in a smoothie, the organisms are rehydrated and they will go on to function normally and reproduce, just as they did before freezing.

Naturally, with exposure to moisture or excessive humidity, freeze-dried probiotics will lose viability over time, so one of the main hurdles when creating a dried probiotic supplement is to ensure the packaging is effective at minimizing exposure to moisture. That is why Puori created SB3 stored inside individual single-use, foil-packed sachets that keep out 99.9% of moisture, thus protecting the precious bacteria from premature activation. This is also a reason why when you tear open your sachet of SB3 you should consume it relatively quickly.

Non-Soluble Fiber

As mentioned earlier, all living organisms need food and probiotic bacteria are no exception. Bacteria feed on insoluble fiber (also known as prebiotic fiber) in the gut such as inulin. These occur naturally in fruits and vegetables so you can obtain insoluble fiber from your diet if it is packed full of fruits and vegetables. But for convenience Puori SB3 is also formulated with additional insoluble fiber (inulin, pectin and fructo-oligosacharides) so that the precious bacteria have a direct food source available so they can thrive when they reach the gut.
