Why Choose Fortify Optima?

When it comes to giving your gut a boost, Nature's Way Fortify Optima is a top pick. This high-strength probiotic packs 100 billion live cultures from 16 diverse strains, plus plant-based prebiotic fiber to keep the good bacteria thriving. With a GP-preferred strain for regularity (HOWARU B. lactis HN019), it's designed for advanced digestive and immune support.*

What Is Fortify Optima Probiotic?

Fortify Optima is a premium probiotic supplement aimed at adults wanting serious digestive and immune care. Each capsule contains 100 billion colony-forming units (CFU) from 16 well-studied strains, including Lactobacilli and Bifidobacteria species. To feed those beneficial bugs, the formula includes a plant-based prebiotic blend of organic blue agave inulin, chicory root, and gum acacia fiber. This combo of probiotics and prebiotics—often called a synbiotic—helps keep your gut microbiome in balance.*

The capsules are acid-resistant, so the live cultures survive stomach acid and reach the intestines where they can do their job. For best results, keep them in the fridge. With a GP-preferred strain for regularity (HOWARU B. lactis HN019), Fortify Optima offers advanced care for digestive balance.*

Key Benefits for Digestive and Immune Health

Your gut health is the foundation of your overall well-being. The live cultures in Fortify Optima work to maintain a healthy balance of gut bacteria, supporting regular digestion and bowel function.* Plus, a big chunk of your immune system lives in your gut, so a robust microbiome also helps your immune defences.*

Each serving delivers 100 billion CFU from a diverse range of strains, targeting both Lactobacilli and Bifidobacteria families. These groups are amongst the most researched for digestive comfort, regularity, and immune resilience.* The prebiotic fibres act as food for the good bugs, encouraging their growth and activity.

Why Strain Diversity Matters

Not all probiotics are the same. A multi-strain formula can target different aspects of gut health. Fortify Optima features 16 strains, including the clinically studied HOWARU B. lactis HN019, a GP-preferred strain for regularity.* This diversity supports a wide range of beneficial functions, from nutrient absorption to immune modulation.*

Lactobacilli strains tend to colonise the small intestine, while Bifidobacteria thrive in the large intestine. By including both, Fortify Optima provides coverage along the entire digestive tract.

Top Ingredients: Prebiotics and Probiotic Strains

The formula combines probiotics with three prebiotic fibres:

  • Organic Blue Agave Inulin: A soluble fiber that selectively feeds beneficial bacteria.
  • Chicory Root: Rich in inulin and fructooligosaccharides (FOS), it supports gut health and regularity.
  • Gum Acacia Fiber: A gentle prebiotic that also aids in digestion and promotes satiety.

The probiotic strains include Lactobacillus acidophilus, Bifidobacterium lactis (HN019), and other species from the Lactobacilli and Bifidobacteria families. Each strain is chosen for its ability to survive transit through the gut and provide targeted support.

How to Choose a High-Quality Probiotic

When picking a probiotic, consider these factors:

  • CFU Count: Higher counts like 100 billion are often recommended for specific therapeutic goals or after antibiotics. Fortify Optima delivers a potent dose.
  • Strain Diversity: Multiple strains provide a broader range of benefits. This product includes 16 well-researched strains.
  • Delivery System: Acid-resistant capsules protect the cultures from stomach acid, ensuring they reach the gut alive. Fortify Optima uses delayed-release capsules.
  • Prebiotics: Prebiotic fibres feed probiotics. The inclusion of organic agave inulin, chicory root, and gum acacia makes this a complete synbiotic formula.
  • Storage: Refrigeration helps maintain potency, though the capsules are stable at room temperature for short periods. Always follow the label instructions.

Frequently Asked Questions

How should I store Fortify Optima?
Refrigerate to keep maximum potency. The capsules are stable for short periods at room temp, but consistent refrigeration is best.

Can I take it on an empty stomach?
Probiotics work best when taken about 30 minutes before a meal, when stomach acid is less concentrated. Follow the label or check with your health care provider.

Is this product vegan?
The capsule is plant-based and the prebiotics are plant-derived. It's likely suitable for vegans, but always check the label for any animal-derived ingredients like gelatin.

How long until I notice results?
Results vary. Some folks notice improvements in digestive comfort within a few days, others may take several weeks. Consistency is key.
