Pros and cons
60 Billion Probiotic
- The brand guarantees 60 billion CFU through expiration, not just at manufacture
- Third-party tested (the brand names Eurofins and Light Labs) and Non-GMO Project Verified
- About 60–83 cents a day, depending on bottle size
- No strain designations, so the formula can't be matched to clinical trials
- Proprietary blend: one total for 10 species, with no per-strain amounts
Pre-Alcohol Probiotic Drink
- One clearly named engineered strain, B. subtilis ZB183, backed by a patent and a published lab study
- Publishes detailed batch-testing specifications, including DNA-sequencing purity, microbial limits and heavy metals
- Shelf-stable, zero calories, in a 15 mL TSA-friendly bottle
- No published or registered human trial, although the company said in 2018 that health claims would wait for one
- $9 to $12 per bottle at brand prices, and $13 for a single bottle
