Why Probiotic Delivery Matters for Digestive Health Supplements

Probiotics are beneficial bacteria that support the gut microbiome. The microbiome influences digestion, immune signaling, nutrient absorption, and even communication between the gut and brain.

However, stomach acid creates a challenging environment. If probiotics do not survive the digestive process, fewer viable organisms reach the intestines.

For this reason, delivery technology plays a central role in the effectiveness of supplements for digestive health.

Dr. Tennant’s® GI 60 Probiotic Formula was developed with this principle in mind.

What Makes Dr. Tennant’s® GI 60 Probiotic Formula Different?

Dr. Tennant’s® GI 60 Probiotic Formula is a synbiotic digestive health supplement designed for daily support.

Key features include:

• 60 billion CFUs from four clinically studied strains
  

• MAKTREK® Bi-Pass Technology for probiotic protection
  

• Targeted prebiotics to nourish beneficial bacteria
  

• Non-GMO, gluten-free, dairy-free, and soy-free
  

Rather than focusing on a long list of strains, GI 60 concentrates on research-supported strains selected for survivability and meaningful daily benefits.

For individuals looking for natural digestive health supplements, this focused formulation supports clarity and transparency.

MAKTREK® Bi-Pass Technology: Designed for Probiotic Survival

Many probiotics are exposed to gastric acid before they reach the intestines.

MAKTREK® Bi-Pass Technology is designed to help protect probiotic strains as they move through the digestive tract. This technology helps support the survival of beneficial bacteria so more of them reach the gut environment intact.

The goal is practical performance during digestion, not just potency listed on the label.

This approach supports GI 60’s role among the best supplements for digestive health for individuals seeking thoughtful formulation and targeted delivery.

Why GI 60 Is a Synbiotic Formula

A synbiotic combines:

• Probiotics, which are beneficial bacteria
  

• Prebiotics, which nourish those bacteria
  

This pairing supports colonization and microbial balance.

GI 60 includes two clinically supported prebiotic sources:

Fructooligosaccharides (FOS) from Chicory Root

A short-chain fiber that supports bifidobacteria and lactobacilli growth.

Marine Polysaccharides from Marine Algae

An innovative fiber selected to support a balanced gut environment and assist probiotic survivability during digestion.

Together, these ingredients support synergy within this digestive health supplement.

The Four Clinically Studied Strains in GI 60

Each strain in Dr. Tennant’s® GI 60 was selected based on research support, survivability, and functional relevance.

Lactobacillus acidophilus La-14

Supports digestive balance and immune function. Widely studied for daily microbiome support.

Bifidobacterium lactis Bl-04

Extensively researched for immune resilience and upper respiratory wellness support.

Lactobacillus plantarum Lp-115

Known for digestive comfort and gut barrier support.

Lactobacillus paracasei Lpc-37®

A clinically studied psychobiotic strain that supports the gut–brain connection, stress resilience, and mood balance.

This targeted approach reflects current research suggesting that strain quality and compatibility matter more than sheer quantity.

How Gut Health Influences Whole-Body Wellness

A large portion of immune activity is associated with the gastrointestinal tract.

A balanced microbiome may support:

• Digestive comfort and regularity
  

• Nutrient absorption
  

• Gut lining integrity
  

• Healthy immune signaling
  

• Gut–brain communication

Modern stress, antibiotic exposure, processed foods, and environmental factors may disrupt microbial balance. Natural supplements for digestive health may help support restoration of that balance when used consistently.

Who May Benefit from GI 60?

Dr. Tennant’s® GI 60 may be appropriate for adults who:

• Experience occasional bloating or digestive discomfort
  

• Want supplements for good digestive health
  

• Seek immune and gut–brain support
  

• Prefer natural digestive health supplements with research-backed strains
  

As with all dietary supplements, individuals with medical conditions should consult a healthcare professional before use.
