Quick Summary

Fortify probiotics contain a proprietary blend of Lactobacilli and Bifidobacteria bacterial cultures, along with plant-based prebiotic fiber to nourish them.

Key Points

  • Diverse Probiotic Strains: Fortify products contain a proprietary blend of multiple bacterial strains, primarily from the Lactobacilli and Bifidobacteria families.

  • Lactobacilli Blend: This blend includes strains like L. rhamnosus GG and L. acidophilus, which are associated with general digestive balance.

  • Bifidobacteria Blend: This component, featuring strains like B. lactis HN019™, specifically supports colon health and promotes regularity.

  • Prebiotic Fiber Included: Many formulas contain chicory root fiber, a plant-based prebiotic that acts as a food source to help the probiotic cultures thrive.

  • Targeted Delivery System: Fortify uses delayed-release, plant-derived capsules that resist stomach acid, ensuring the live cultures reach the intestines.

  • Formula Varies by Product: The exact ingredients and CFU counts differ between Fortify products, such as the Daily, Women's, or 50+ formulations, to target specific needs.

Understanding the Fortify Probiotic Formula

Fortify probiotics are developed with a specific, multi-strain approach to support overall digestive wellness and immune health. Instead of just one or two types of good bacteria, the formula incorporates a proprietary blend of bacterial cultures, which can vary depending on the specific Fortify product, such as the Daily 30 Billion, Daily 50 Billion, or Women's formulas. These blends are primarily composed of two main families of probiotics: Lactobacilli and Bifidobacteria.

The Probiotic Blends: Lactobacilli and Bifidobacteria

The core of the Fortify product line is its proprietary probiotic blend. The proportions and specific strains within this blend differ based on the product's intended purpose, such as everyday care, women's health, or for adults over 50. However, most formulas feature a significant number of both Lactobacilli and Bifidobacteria strains.

  • Lactobacilli Blend: This group of bacteria is a cornerstone of Fortify probiotics. Common strains include Lactobacillus casei, Lactobacillus rhamnosus GG, Lactobacillus paracasei, Lactobacillus acidophilus, and Lactobacillus plantarum. These strains are often associated with supporting digestive balance and are commonly found in fermented foods. Some formulations, like the Daily 30 Billion, can have a Lactobacilli blend with billions of CFUs (Colony Forming Units).

  • Bifidobacteria Blend: The Bifidobacteria blend works alongside the Lactobacilli to support the colon. Common strains found in various Fortify products include Bifidobacterium bifidum/lactis, Bifidobacterium lactis, and HOWARU® Bifidobacterium lactis HN019™. This blend is particularly noted for supporting regularity and overall colon health. The specific CFU count for the Bifidobacteria blend also varies by product.

Additional Ingredients: Prebiotics and Capsule Components

Beyond the live cultures, Fortify probiotics include other ingredients to ensure the efficacy and delivery of the product. These include:

  • Chicory (root) Fiber: Included as a prebiotic, this plant-based fiber serves as a food source for the good bacteria in the supplement, helping them flourish and survive. Prebiotics are non-digestible components that promote the growth of beneficial microorganisms.
  • Plant-Derived Capsule: The capsules themselves are a key component of Fortify's delivery system. Made from ingredients like hypromellose and gellan gum, the delayed-release capsules are designed to survive the harsh stomach acid. This ensures that the live probiotic cultures are distributed where they are needed most—in the intestines and colon.
  • Other Ingredients: Minor additions include cellulose, magnesium stearate, and silica, which serve various functions in the manufacturing process, such as preventing clumping.

Conclusion: A Multi-Ingredient Approach to Gut Health

Fortify probiotics are more than just a single bacterial strain; they are a multi-ingredient supplement built on a foundation of diverse probiotic cultures. By combining multiple beneficial bacteria from both the Lactobacilli and Bifidobacteria families, Fortify aims to support a balanced intestinal tract. The inclusion of prebiotic fiber provides nourishment for these cultures, and the delayed-release capsule ensures they are delivered effectively to the gut. The specific combination of ingredients varies across the product line, allowing consumers to choose a formula tailored to their individual health needs. Understanding what are the ingredients in Fortify probiotics is crucial for anyone looking to make an informed decision about their digestive health supplements.
