What Are Soil Based Probiotics?

Simply put, soil based probiotics are the kind of bacteria found in the soil and have evolved over time due to the constant contact with humans.

There has, however, been some debate on whether or not soil based probiotics do more harm than good, with one school of thought lauding it as the best thing for natural gut health.

Another group, however, is of the notion that these kinds of bacteria might not be all that expect them to be. They believe that the sheer number of options available can present some bacteria choices that are dangerous and pose a threat to human immune systems.

While both arguments certainly have their own merits, it’s difficult to argue fully against humans going back to the way things were before. After all, long before industrialization, humans came in constant contact with the ground through farming, hunting, and eating.

That being said, some bacteria are quite dangerous, just as some are beneficial and knowing the difference is what can help you choose the best soil-based probiotics for your gut health.

Which Soil Based Probiotics Are Good for You?

Some soil-based probiotics such as Bacillus subtilis are quite simply part of our natural microbiome. These probiotics are well known for forming spores that are quite resilient and capable of surviving most harsh conditions, such as those found within the human gut. This includes high temperatures, acidity, and irradiation. They also happen to be the most studied type of soil based bacteria.

The thing about soil based bacteria is that they are known to be good for our health in general. This is because they help us maintain optimum health as far as our digestive and immune systems are concerned.

The biggest issue, however, is that, unlike most other types of bacteria, soil based probiotics have a habit of colonizing the digestive tract. That being said, Bacillus probiotics still come with more health benefits when compared to other highly studied options such as Bifidobacterium and Lactobacillus, which are also strains that you will commonly find in probiotic options in the market. But which Bacillus strains are the best for you, and what are their benefits?

  • Bacillus coagulans: Studies have shown that this strain of bacteria positively affects diarrhea, abdominal pain, bloating, and even constipation.
  • Bacillus subtilis: Some studies have shown that this type of bacteria is good for many health issues such as constipation and even irritable bowel syndrome. These bacteria have been studied in heavy combination with another probiotic known as Enterococcus faecium, which effectively manages IBS, H. Pylori, and even constipation. There’s additional research to show that laxatives with this type of bacteria (Bacillus subtilis) as part of their ingredients are more effective than those that don’t.
  • Bacillus clausii: There’s research that shows that this kind of bacteria is extremely effective in reducing the typically severe side effects of H. Pylori medication, such as diarrhea, pain, and nausea.

Is It Safe to Use Soil Based Probiotics?

As mentioned earlier, there are conflicting arguments on this front, with some scientists believing these soil based bacteria aren’t as safe as many people claim them to be. The biggest issue has been that these soil based probiotics are known to colonize the gut and are looked upon as an invading force that can harm the human intestinal tract. In some circles, it’s believed that these spores can trigger severe immune responses in patients who already have compromised immunities.

As you can imagine, both sides of the argument have evidence to support their claims. As far as those who are for using soil based probiotics to better human health, their arguments lie around the probiotics above with health benefits above.

However, some soil based probiotics have been known to be harmful to the human body. The most notorious bacteria in this category is “Bacillus anthracis,” also known as Anthrax. Anthrax is so dangerous that it kills people if you are exposed and don’t get immediate treatment. Apart from that, there are other species of the Bacillus bacteria that have been known to bring about near-deadly food poisoning symptoms.

That being said, taking the best kind of soil based probiotics for your gut health is by far one of the most effective courses of action you can take if you aren’t too keen on going down the medication route. The options reviewed above are safe and quite effective as far as developing better gut health is concerned.
