Forms Comparison
| Form | Bioavailability | Best For |
|---|---|---|
| Refrigerated Capsules | High | Maximum viability — cold chain maintains colony counts through shelf life |
| Shelf-Stable Capsules | Moderate-High | Convenience — freeze-dried technology preserves viability without refrigeration |
| Fermented Foods (yogurt, kefir) | Variable | Dietary approach — provides live cultures plus food matrix benefits, but strain/dose less controlled |
