Do I still need a separate probiotic if I'm taking LYMA ID²?

No. LYMA ID² already pairs 3 billion CFU of ActiBio® with 8.5g of multi-length prebiotic fiber, so the bacteria arrive with a food source that helps them survive stomach acid and establish in the gut.

Standalone probiotics typically lack this fiber pairing, which limits how many of the bacteria actually colonize. Adding another probiotic on top isn't harmful, but it's not necessary.
