Nitrolithic Labs | Gutriva40 Probiotic | 40 Billion CFU +Prebiotics | 60 Caps | Gut Health

Gutriva40 doubles the CFU count of Gutriva20 and adds a small prebiotic dose (24 mg FOS). Probiotics introduce beneficial bacteria. Prebiotics feed them. The combination is called a synbiotic.

What's inside and why it matters:

1. 40 billion CFU per serving: Twice the CFU of Gutriva20, for adults who want more daily support.
2. Prebiotic fiber (FOS, 24 mg): Selectively feeds beneficial bacteria, giving them a competitive advantage over less beneficial microorganisms.
3. Multi-strain formula: Includes L. acidophilus (La-14), B. lactis (Bl-04), L. plantarum (Lp-115), and L. paracasei (Lpc-37), with MAKTREK® Bi-Pass Technology.

Here's the Science

Every strain is listed by its strain code (La-14, Bl-04, Lp-115, Lpc-37), so you can look up the research on the exact strains in this bottle.

Suggested use: Two capsules daily.
