Spore-forming probiotic that survives stomach acid well
We rank Bacillus Coagulans by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Bacillus Coagulans is a probiotic, which is a type of friendly bacteria that provides health benefits when added to the diet. Unlike many other probiotics, it is spore-forming, meaning it creates a hard protective shell around itself to survive harsh conditions.
It is primarily used to support digestive health. Because of its protective shell, it survives stomach acid well, allowing the live bacteria to reach the intestines where they can be effective.
The bacteria are grown in large industrial fermentation tanks where they are fed a specific nutrient broth. Once the bacteria form their protective spores, the mixture is filtered and dried into a stable powder that can be put into capsules or mixed into other supplements.
This ingredient is generally affordable. This is because the bacteria are hardy and easy to mass-produce in large quantities, and there is significant global competition among manufacturers.
