THE PROBIOTIC COLLECTION

Your gut is
your second brain.

Your gut microbiome — trillions of bacteria living in your digestive tract — shapes your immunity, your mood, your skin, and your metabolism. Probiotics are the beneficial bacteria that keep that ecosystem balanced. When the balance shifts, everything downstream shifts with it.*

PROBIOTICS 101

What probiotics are, and how to choose.

Probiotics are one of the most popular supplement categories — and one of the most confusing. Here's what CFUs really mean, why strain diversity matters more than raw count, and what to look for on a label.*
01

What Are Probiotics?

Probiotics are live beneficial bacteria. They temporarily colonize your gut, supporting digestion, nutrient absorption, immune function, and even mood — via the gut-brain axis. Think of them as reinforcements for an ecosystem that's constantly under stress from diet, antibiotics, and lifestyle.

02

Strains Matter Most

Different strains do different things. Lactobacillus supports digestion and vaginal health. Bifidobacterium supports bowel regularity and immune function. Saccharomyces boulardii is a beneficial yeast that survives antibiotics. Multi-strain formulas outperform single-strain for most people.

  • BIFIDOBACTERIUM · IMMUNITY & REGULARITY
  • SACCHAROMYCES BOULARDII · ANTIBIOTIC RECOVERY

03

CFUs Decoded

CFU (colony-forming units) measures live bacteria count. More isn't always better — 5–50 billion CFU covers most needs. What matters more is delivery: acid-resistant capsules, guaranteed potency through expiration (not just at manufacture), and strains backed by clinical research.

04

What to Look For

Multiple researched strains (not just one), guaranteed potency through expiration, acid-resistant delivery, and prebiotic fiber to feed the bacteria. Every product comes with a Certificate of Analysis (COA) for verified potency. That's the only kind we carry.
