What’s the Difference Between Probiotics?
Spore-Based v. Standard
You walk down the supplement aisle and notice a new buzzword on the probiotic bottles: “spore-based.” You wonder what that actually means and whether it is better than what you are already taking.
Here is the simple truth. Most standard probiotics are incredibly fragile. You swallow the capsule and it drops into your stomach, which is basically a pool of acid designed to kill bacteria.
Some high-quality, pharmaceutical-grade probiotics have found ways around this problem. But many standard probiotics do not survive the trip. They never make it to the intestines where they are supposed to do their job.
Spore-based probiotics work differently.
Think of them like seeds with a hard outer shell. They wear a coat of armor that protects them from stomach acid. They stay dormant, almost like they are asleep, until they travel down toward your colon. Once they arrive in the safe zone, they hatch and get to work.
This matters a lot for people with SIBO, which stands for Small Intestinal Bacterial Overgrowth.
If you have SIBO, the last thing you want is to dump billions of live bacteria into your small intestine. You would be adding more bacteria to a place where you already have too many.
Because spore-based probiotics stay dormant until they reach the large intestine, they do not fuel the overgrowth that happens with SIBO.
I like to think of spore-based probiotics as compost for your garden. They help the good bacteria grow without promoting overgrowth in the wrong place.
Now, I do not want to give the impression that you should ditch your regular probiotics. Standard probiotics have their place and work well for most people, especially the high-quality ones.
The two types often work well together. In my experience, it can help to start with spore-based probiotics to prep the terrain, and then follow up later with regular quality probiotics.
Here is something to pay attention to. Do standard probiotics seem to make you worse? Do they leave you feeling bloated or gassy? That could be a clue that you have SIBO.
If that sounds like you, talk to your doctor about it. A spore-based probiotic might be the better starting point.
