What is BioCeuticals UltraBiotic 500 and who is it for?
UltraBiotic 500 is a high-potency probiotic powder from BioCeuticals, formulated with fourteen bacterial species across the Lactobacillus, Bifidobacterium, and Streptococcus genera. It comes in individual sachets and is intended for adults who want to support healthy digestive system function and maintain beneficial gut flora.
You might consider this if you’re looking for a multi-species probiotic powder rather than a capsule, or if you’re focused on supporting bowel regularity and digestive system health. It’s also relevant after antibiotic use, where restoring beneficial gut flora is a common priority.
Fairfield Nutrition Thoughts
BioCeuticals is a well-regarded Australian practitioner brand, and UltraBiotic 500 sits at the higher-potency end of their probiotic range. The fourteen-species formulation covers both Lactobacillus and Bifidobacterium genera at meaningful amounts, and the individual sachet format offers practical convenience for short-term use or travel while protecting contents from moisture and light. It’s a sensible option for those focused on restoring beneficial gut flora after antibiotic use or supporting bowel regularity during periods when digestive system health needs attention.
Why This Formulation / How It Works
UltraBiotic 500 is a powder-format probiotic delivered in individual sealed sachets. The sachet format protects the contents from moisture and light between doses, which supports viability through to the end of the pack. The formula contains fourteen bacterial species: twelve from the Lactobacillus genus, two Bifidobacterium species, and Streptococcus thermophilus, with total CFU counts declared per gram across all species.
The species included span both the small and large intestinal regions where Lactobacillus and Bifidobacterium species are naturally found. Bifidobacterium animalis ssp lactis appears at two declared amounts in the formula, and Lactobacillus rhamnosus similarly appears at two declared amounts.
Species Composition
The formula leads with Bifidobacterium animalis ssp lactis at 44 billion CFU/g, followed by Lactobacillus acidophilus and Lactobacillus paracasei at 10 billion CFU/g each, and Lactobacillus salivarius ssp salivarius at 8 billion CFU/g. The remaining species contribute at amounts ranging from 1 to 6 billion CFU/g, rounding out a broad-spectrum multi-species profile.
When to Consider This
This probiotic powder makes sense if you’re:
- Taking or recently finishing a course of antibiotics and want to help restore beneficial gut flora
- Focusing on bowel regularity and healthy digestive system function as part of your daily routine
- Looking for a powder-format probiotic in individual sachets rather than a capsule or tablet
- Working with a healthcare professional on gastrointestinal system health
