Side by Side
| Bifidobacterium longum 35624 | Multi-Strain Blends (Unstudied) | |
|---|---|---|
| How it works | Acts in the gut lumen. In the main IBS trial, 100 million CFU improved symptoms and 10 billion CFU did not, likely because the high-dose capsule formulation clumped. | Combinations assembled for marketing rather than tested as a product. Strain designations are often missing, and CFU may be counted at manufacture rather than expiration. |
| Typical dose | 100 million CFU daily | Varies |
| Common uses | IBS | general gut health (unproven) |
| Side effects | Bloating. | Gas, bloating. |
| Cost | Moderate | Moderate |
| Also called | Align, B. infantis 35624 | 50 billion CFU blends, 10-strain formulas |

There is rarely a reason to choose unstudied multi-strain blends: choose a strain matched to a trial instead. The trials that support probiotics tested specific strains, not blends built from their species names.
Multi-Strain Blends (Unstudied)
There is rarely a reason to choose unstudied multi-strain blends: choose a strain matched to a trial instead.
