Spore Probiotic

Costco-priced spore probiotic with DE111 B. subtilis (clinically studied). Spore-based means near 100% stomach acid survival. Two strains is minimal but at 1/3 the price of MegaSporeBiotic, it's the budget entry point to spore probiotics.

7.0/10
VERY GOOD

Spore-based probiotic with two strains totaling 8 billion CFU. B. subtilis DE111 at 3B CFU is a clinically studied strain at an effective dose. B. coagulans at 5B CFU adds well-researched support. Spore-forming strains survive stomach acid without refrigeration. No score data for B. coagulans in our system, but it is well-studied. Good entry-level spore probiotic at Costco pricing.
