L. Reuteri vs Other Probiotic Strains
Lactobacillus reuteri is one of the more researched probiotic strains for
home fermentation, but it’s easy to confuse with other common strains. This
is a sample article — edit it in Keystatic (/keystatic) or replace it
entirely with your own writing.
How L. reuteri compares
| Strain | Common source | Notable trait |
|---|---|---|
| L. reuteri | Human gut, BioGaia Gastrus | Produces reuterin, an antimicrobial compound |
| L. acidophilus | Yogurt, kefir | Widely available, well studied |
| L. plantarum | Fermented vegetables | Tolerates a wide pH and temperature ranges. |

How much bacteria is actually in that spoonful?
Colony-forming units (CFU) per typical serving, commercial probiotics vs. a home multi-strain yogurt.
* The homemade multi-strain figure isn't an independent lab measurement — it's a single home flow-cytometry count reported by Dr. William Davis for his 36-hour L. reuteri ferment, and it isn't clear whether it reflects the whole batch or one serving. Treat it as an order-of-magnitude anecdote, not a verified dose.
Commercial CFU counts are manufacturer label claims at time of manufacture, not guaranteed counts at the point of consumption.
Seed DS-01 reports potency in AFU rather than CFU — shown here for scale, not as a like-for-like count.
Benefits
- Naturally occurring in the human gut and breast milk
- Studied for oral health and gut barrier support
- Ferments well in dairy at a slightly lower temperature than yogurt starters
Making L. reuteri yogurt at home
A short guide would go here: starter ratio, incubation temperature and time, and troubleshooting a thin or overly sour batch.
