New research analysed 352 probiotic supplements. What they found will change how you think about gut health entirely.
You've probably tried probiotics. Most Australians have. And most noticed... not much.
There's a reason for that. Two reasons, actually. And once you understand them, the billion-dollar probiotic supplement industry starts to look very different.
Problem 1: Stomach acid kills them on arrival.
Your stomach is designed to destroy bacteria. That's its job — to protect you from pathogens. And it's very good at it.
The problem is that probiotic supplements contain live bacteria. Bacteria that need to survive a journey through one of the most acidic environments in your body before they can do anything useful.
Most don't make it. Research published in the Journal of Applied Microbiology found that unprotected probiotic bacteria can lose more than 99% viability passing through the acidic conditions of the stomach — before they ever reach the gut where they're actually needed.1
So the label says 10 billion CFU. By the time anything reaches your intestines, you might be working with a fraction of that — if you're lucky. And that's before we get to problem 2.
Problem 2: The science behind most formulations doesn't exist.
"There was no real consistency in the combination of species used to support gut health, vaginal health or other health claims."
Researchers at the University of Virginia analysed 352 over-the-counter probiotic supplements sold at the three largest pharmacy chains in the United States. What they found was startling.
The scientists concluded there was no scientific consistency in how probiotic products are formulated. The strains included appear to be marketing decisions, not clinical ones.
In other words: even if a probiotic survived the journey to your gut, there's no strong scientific basis for most of what's in the capsule in the first place.
So what actually works?
Your gut already contains trillions of bacteria — somewhere between 38 and 100 trillion, depending on the individual. A healthy microbiome isn't about adding new bacteria to that ecosystem. It's about feeding and strengthening the ones already there.
That's what a prebiotic does. And Turkey Tail mushroom is one of the most studied natural prebiotics on the planet.
Unlike probiotic supplements, Turkey Tail doesn't need to survive stomach acid. It works by providing the fuel — polysaccharides like PSK and PSP — that beneficial bacteria in your gut need to thrive.
- Works with your existing gut bacteria, not against stomach acid
- PSK and PSP compounds — among the most studied mushroom polysaccharides
- Certified organic whole food — no extracts, no fillers
- Freeze-dried to preserve the full nutrient profile
- 9,000+ verified customer reviews
