Why Natren Probiotics Are Different and Why That Matters

 

Since 1982, Natren has been a pioneer in probiotic science. Unlike many brands that outsource production to third-party manufacturers, Natren maintains full control over its process, from formulation to final product. This unique in-house approach allows us to focus exclusively on one thing: making the highest-quality probiotics possible.

We Don’t Just Make Probiotics—We Live and Breathe Them

Many probiotic products are mass-produced using industrial methods that compromise the integrity of the bacteria. A common step in these processes involves separating out the growth medium (the bacteria’s natural food source) using centrifugation. This may be efficient, but it can damage the cell wall of the bacteria—meaning you could be taking probiotics that are already weakened before they reach your digestive system.

At Natren, we do things differently. Our probiotics are produced in small batches and always include the original growth medium, known as the supernatant. This gives the bacteria the nourishment they need to survive and replicate once ingested. You’re taking live, active cultures that are ready to thrive in your gut, not bacteria that are already deteriorating.

What If Probiotics Haven’t Worked for You?

Good probiotics can help around 80% of the time—but what about those cases where they don’t? In our experience, this is where Natren makes the difference.

Because we only make probiotics—and have done so for over 40 years—every part of our process is dedicated to preserving the potency and viability of our strains. That’s why healthcare practitioners across the world trust Natren, and why our customer base has remained loyal over decades.

Protecting Probiotics from Their Biggest Enemies

Live bacteria are extremely delicate and vulnerable to three main threats: oxygen, moisture, and heat. We take all three seriously. Every Natren probiotic is:

• Cold chain from production to delivery
• Packed in dark glass bottles to block light and heat
• Flushed with nitrogen to remove oxygen
• Sealed with an inner and outer seal plus a metal cap for added protection

This attention to detail helps ensure that the bacteria remain stable and effective when they reach you.

Why Our CFU Counts Are Lower—By Design

Some probiotic companies promote extremely high CFU (colony-forming unit) numbers, suggesting more is better. But this isn’t always the case. Crowding billions of bacteria into a capsule can damage their cell walls, and if they’re not stored correctly, their numbers drop rapidly—especially when left on a shelf for months.

In contrast, Natren provides live bacteria in a condition where they can replicate rapidly once ingested. Just a few billion viable cells, in the right environment, can multiply into 50 billion or more—as long as they’re alive. That’s why survival and growth matter more than the label count.

Fingerprint Testing for Quality and Purity

Each strain in our products is originally frozen and cryo-protected. Every batch produced is then fingerprint-tested against the original to ensure purity, viability, and precision. This guarantees you’re getting exactly the right strain—every single time.

Why Choose Natren?

Because with Natren, you’re choosing more than just a probiotic—you’re choosing over 40 years of expertise, quality control, and a commitment to doing things the right way. If you’ve tried probiotics before and not seen the results you hoped for, Natren could be the difference.
