Extra Strength Probiotic
Over 35 billion beneficial organisms from lactobacillus and bifidobacterium genera
Additional benefits of prebiotic fructooligosaccharides.

If your digestion feels off more days than not — bloating, irregularity, or a gut that never quite settled after antibiotics — the balance of bacteria in your gut is usually where to start. Flourish Extra Strength Probiotic delivers 35 billion CFU of well-studied Lactobacillus and Bifidobacterium strains with prebiotic fiber (FOS) to help beneficial bacteria establish, crowd out less-desirable organisms, and support steady digestion and immune balance.
| Brand | Flourish Rx |
| What it is | 35 billion CFU multi-strain probiotic + prebiotic FOS |
| Form | Capsules |
| Storage | Shelf-stable — no refrigeration |
| Best for | Everyday digestive & immune balance |
| Pairs well with | Flourish Biotic DF, MegaPrebiotic, a fiber-rich diet |
This is a daily wellness probiotic, not a treatment for acute GI illness. Persistent pain, blood in the stool, or fever warrants a call to your provider.
Your gut is a competitive place — bacteria constantly compete for space, and when less-helpful organisms gain ground, digestion suffers. This probiotic adds a concentrated dose of beneficial Lactobacillus and Bifidobacterium, and the prebiotic FOS gives them a food source so they can establish rather than simply pass through. A more balanced microbiome supports regularity, comfortable digestion, and the gut-based immune system.
Take one capsule daily, or as directed by your healthcare practitioner.
Flourish is a compounding pharmacy with an on-staff pharmacist and nutrition team, so your questions about gut health reach people who do this every day — not a warehouse. Explore Probiotics, Gut Health, or pair it with Flourish Biotic DF, MegaPrebiotic, Restorflora.
What's the difference between this and a regular probiotic?
It pairs a higher 35-billion-CFU count with prebiotic FOS, so the beneficial organisms arrive with a food source that supports colonization rather than just passing through.
Does it need refrigeration?
No — it is shelf-stable and does not require refrigeration.
Can I take it with antibiotics?
Yes, but space it a few hours apart from the antibiotic dose.
When should I take it?
Any time of day works; many people take it with a meal.
How is it different from Flourish Biotic DF?
This is a higher-CFU probiotic with added prebiotic; Flourish Biotic DF is a focused four-strain formula in acid-resistant capsules. Some people use one or the other; some rotate.
How long until I notice a difference?
Gut changes build over time; give it a few weeks of consistent use.
Is it dairy- or gluten-free?
