Probiotic Balance
Comfort, from the inside.
Probiotic Balance delivers 60 billion CFU across 5 clinically studied strains in two daily vegetable capsules. MAKTrek Bi-Pass Technology helps the cultures survive stomach acid and reach the gut intact, while prebiotic FOS and marine polysaccharides give them what they need to thrive. Shelf-stable, no refrigeration, and gentle enough for everyday use.
- Supports a balanced, diverse gut microbiome
- Promotes digestive comfort and everyday regularity
- Helps maintain healthy gut flora, including after antibiotic use

What it helps with

How it works in your protocol
Most supplements are a guess. Agen earns every capsule from your own data — the measure → analyze → act loop.
Measure
The Band tracks your HRV, sleep and resting heart rate; the app reads your stress load across the day.
Analyze
When recovery dips and stress climbs, Agen flags adaptogenic support — and scores the evidence behind it.
Act
It enters your daily protocol at the right dose, dispensed by the Robot each evening.
What the science says
Every claim scored by evidence strength — including the ones that aren’t there yet.
Early signals only — the honest answer is the evidence isn't conclusive yet. We'll update this the moment it is.

Pretty pleased with this. Easy capsule and no aftertaste at all.
Exactly what I was hoping for. No bloating and sits comfortably.
Does everything I wanted it to. Easy capsule and no aftertaste at all. Exactly as described on the product page.
Couple of issues stopped me enjoying it. Unfortunately the seal on my bottle wasn't intact on arrival.
We really appreciate you flagging this. We'd love to help — drop us a line at support@agen.com and we'll sort a replacement or refund.
Top quality, no notes. No bloating and sits comfortably. I've stuck with it daily and it's an easy habit to keep.
