The Science Inside

Your digestive system is a connected ecosystem. Different areas of the GI tract benefit from different probiotic strains. UltraFlora® Spectrum combines seven clinically researched strains selected to support multidimensional gut balance.

Each capsule provides 30 billion live organisms, including:

• Saccharomyces boulardii: Studied for its role in supporting gastrointestinal balance, including during travel and antibiotic use.*
• Bifidobacterium lactis Bl-04 & Bi-07: Recognized for supporting gastrointestinal health and promoting favorable gut flora. Studied in immune response research.*
• Lactobacillus acidophilus NCFM®: One of the most researched probiotic strains, evaluated in 330+ publications and 60+ human trials for digestive and immune support.*
• Lactobacillus plantarum Lp-115: Studied for its role in maintaining a healthy gut environment.*
• Streptococcus thermophilus St-21: Included to complement overall digestive support.*

Together, these strains provide broad-spectrum support for both upper and lower GI tract health.*

Why Strain Diversity Matters

Different probiotic strains perform different functions. A multi strain probiotic allows for complementary activity across the digestive tract.

Research shows:

• Bifidobacterium lactis strains support gastrointestinal health and promote favorable gut flora.
• Bifidobacterium lactis Bl-04 and Lactobacillus acidophilus NCFM® have been studied for immune response support.
• Saccharomyces boulardii has been evaluated in research for supporting gastrointestinal balance during antibiotic use and travel.
• Lactobacillus acidophilus NCFM® has demonstrated lactase activity and has been studied in digestive comfort research.

UltraFlora® Spectrum provides multidimensional daily support for both the upper and lower GI tract for digestive and immune health.*
