Align (Bifidobacterium infantis 35624), Digestive Advantage IBS and VSL#3 all of which have research studies which show efficacy for IBS sufferers.

Here are a few links that show what the most researched-backed probiotic strains/products are:
A Gastroenterologist’s Guide to Probiotics (2012): https://www.ncbi.nlm...424311/#S8title
World Gastroenterology Organisation Global Guidelines (updated yearly): http://www.worldgast...biotics-english
4th Triennial Yale/Harvard Workshop on Probiotic Recommendations (2015): https://www.research...Use-2015_Update
Despite these links, there will still be very significant person to person variation, so you kind of just have to test multiple products for yourself.
An important thing is the strain identifier. For example, for Culturelle (Lactobacillus rhamnosus GG), the genus is Lactobacillus, the species is rhamnosus and the strain is GG. Strains are extremely important. A different strain of the same species can have very different effects.
Another important factor is whether the strain was sourced from food (fermented or otherwise) or the human gut. Again, this difference will make a big impact as ones found in the human gut are adapted to that environment and are filling native roles.
"Synbiotic" is used when a product contains both probiotics and prebiotics. Because the word alludes to synergism, this term should be reserved for products in which the prebiotic compound selectively favors the probiotic compound. The primary synbiotic I know of is with Culturelle & mushrooms. So taking those in the same meal will have different effects than taking them separately. Bimuno (GOS) also has a bifidogenic effect.
Phages (bacteriophage) are viruses that only infect/kill bacteria. They have a "population control" type role. There are 4 of the same phages which are in every phage product currently on the market. They are: LH01 - Myoviridae; LL5 - Siphorviridae; T4D - Myoviridae; LL12 - Myoviridae. "Nutrivee Advanced Prebiotic" is the cheapest phage product I've found.
Since fermented foods are not human-sourced they will have very different effects from specific probiotic strains, and thus are NOT a replacement for probiotics. Fermented foods can both help & harm, depending on person to person variation. In my opinion their benefits are typically way oversold.
Below is a list of the known source of strains:
You can PM me for additions so I can keep this updated. If google will not tell you the source you'll have to contact the company and ask. The vast majority are food-sourced so it might be easier to just keep a list of human-sourced.
Culturelle (L.GG): https://en.wikipedia....28ATCC_53103.2
Align (b.infantis 35624): http://www.bifantis....f/Monograph.pdf
BioGaia Gastrus: https://www.biogaia....biotic-strains/
Lactobacillus gasseri CP2305: http://www.sciencedi...756464617300543
Super Human Probiotics - claims to have 15 human-sourced strains + 4 food sourced: https://elementalwiz...uman-probiotics
VSL#3: https://vsl3.com/faq/ - from what I can tell, the only thing unique about this product is the high CFU count.
Most/all Garden Of Life products: See the label.
- Reuteri pearls. - company does not know.
