At doTERRA, we’re committed to creating products that don't just sound good—they need to be backed by science. That’s why we put PB Restore, our new probiotic supplement, to the test in a full clinical study. The goal was simple: see how PB Restore affects gut health, quality of life, and digestive comfort in real people.

Here’s a breakdown of what the study found—and what it could mean for you.

Why the Gut Matters

Imagine your gut like a bustling city, filled with millions of tiny citizens—bacteria, yeasts, and viruses—all working together to keep things running smoothly. This city is called your gut microbiome. When the right mix of citizens (good bacteria) thrive, your digestion, mood, immune system, and even energy levels can feel balanced and strong.

But stress, aging, diet, and modern lifestyles can cause chaos in this city, letting the “bad guys” outnumber the “good guys.” That’s where probiotics come in: they’re like sending in reinforcements to restore order and help your gut city thrive again.

The PB Restore Study: How It Worked

Who:

• 62 healthy adults between the ages of 40–60 joined the study.

What they did:

• Took one PB Restore capsule every day for 30 days, with a meal.

What PB Restore contains:

• A powerful mix of 24 probiotic strains, prebiotics (food for good bacteria), and bacteriophages (tiny helpers that keep bad bacteria in check).

What we measured:

• Changes in their gut bacteria (through stool samples)
• Their quality of life (through surveys)
• Their digestive comfort (also through surveys)
• Any side effects or safety concerns

The Highlights: What Changed

1. Gut Health

Researchers looked at whether PB Restore helped the gut become a healthier, more balanced environment.

• Overall gut diversity improved slightly (diversity = lots of different types of bacteria, which is good for resilience).
• Heart-health-related gut bacteria changed significantly.
• Digestive-health related gut bacteria also shifted—but in some cases, the shifts weren’t as positive as expected.

Important to Know:

Sample handling might have affected the results. Stool samples traveled by mail, sometimes sitting for days at different temperatures. So while some numbers changed, researchers think future studies with faster lab testing might show clearer results.

2. Quality of Life (How Participants Felt Overall)

Participants answered questions about how they were feeling—physically, mentally, and socially.

• More energy: Participants could do more vigorous activities like lifting and exercising.
• Less social limitation: Participants felt freer to socialize without health holding them back.
• Happier mood: Participants spent less time feeling down or “blue.”

Analogy:

Think of your body like a phone battery. A healthy gut may help "charge" your energy and mood so you can tackle the day without running low.

3. Digestive Comfort

People also rated their digestive comfort weekly. The results were clear:

• Less bloating
• More comfortable digestion
• Less feeling self-conscious after meals
• Fewer food avoidances

After one month, 40% of digestive comfort areas improved significantly, even when adjusting for strict math checks (called Bonferroni corrections).

4. Safety and Tolerability

Good news here too:

• No serious problems were reported.
• About 12% of people had mild stomach symptoms (like gas or bloating), but these went away without needing medical care.

Bottom line: PB Restore was safe and well-tolerated for daily use.

What Makes PB Restore Different?

PB Restore isn’t just any probiotic. It's like a three-part team working for your gut:

1. Probiotics: Good bacteria that help balance your gut.
2. Prebiotics: Food for the probiotics, helping them grow strong
3. Bacteriophages: Special agents that hunt down bad bacteria without hurting the good guys.

This full-circle approach supports the gut environment naturally and intelligently.

Study Limitations: Why Caution Matters

Even though the results were exciting, researchers pointed out a few things:

• Mailing in stool samples might have affected the quality of the gut bacteria results.
• No placebo group (a group that didn’t take PB Restore) was included, so it’s harder to say exactly how much change was caused by the supplement.
• The study only lasted 30 days—longer studies might show bigger results.
• Participants were mostly healthy, middle-aged adults, so we don't yet know how PB Restore might work in younger people or those with digestive conditions.

Future plans include longer, more diverse studies to confirm and expand on these findings.

What This Means for You

Even in just 30 days, PB Restore showed promising signs of supporting:

• Energy and mood
• Digestive comfort
• Physical and social activities

And it did this safely and gently.

While more research is needed, PB Restore could be a helpful way to support your gut health, feel more comfortable in your body, and live life a little more freely.

At doTERRA, Science Matters

This study is part of our commitment to science, safety, and transparency. We're excited about these first results and look forward to learning even more about how PB Restore and other natural solutions can help people feel their best—from the inside out.
