Probiotics: human grade vs dog specific

Postby Amanda » Fri Apr 20, 2018 3:10 pm

Does anyone have info about using a human grade probiotic vs a humans’ supplement? I’m in a conversation about Purina’s fortiflora supplement and there was some push back on my suggestion that they could just purchase a human supplement instead. The argument was that dog gut flora differs from ours and so a human supplement would not be as effective. Just wondering if this is true and if anyone knows of studies or resources to check out?

I'm curious about this, but skeptical about the claim that the gut bacteria is that different.
I went to the FortiFlora site and found that the ingredient they mention is Enterococcus faecium.

Okay, what's that? "Enterococcus is a large genus of bacteria to which the species Enterococcus faecium belongs. This bacterial species is gram-positive, spherical, and often occurs in pairs or chains, rather than clumps.[2] Mammals, including humans, usually have Enterococcus colonies already in and on their bodies, particularly in the gastrointestinal tract and on the skin." ... ic-strain/

Wikipedia and multiple other sites tell me that enterococcus faecium is found in the guts of both humans and dogs. I look to see if it's an ingredient in probiotics for humans, and yep, it is. In many of them.

So on a 10-minute inquiry, I would say that FortiFlora is not superior to human-grade probiotics, so long as the human-grade probiotic being used contains enterococcus faecium.

FortiFlora contains a few other things that dog owners might want to administer -- some low doses of vitamins C and E -- but as a probiotic, I can't see how it's superior.

Ingredients (Dry)
Animal digest, Enterococcus faecium, L-ascorbyl- 2-polyphosphate (source of Vitamin C), Vitamin E supplement, zinc proteinate, beta-Carotene, salt, manganese proteinate, ferrous sulfate, copper proteinate, calcium iodate, sodium selenite.

So I'm curious too.

I don't have any scientific facts for you but I have given Gringo only human grade probiotics his whole life and I can absolutely see a big difference when he doesn't get them daily which tells me they are working very well for him. I used to give G Jarrow then switched to NOW brand 4x6 a few/several years ago.

Trainer friend E also gives her dogs human grade probiotics.

Not true.

I typically recommend human grade products, since they don't have crappy fillers/additives and are at least a little better regulated. They work, the evidence is in the results.

Remember, what goes in comes out, so you can "culture" anything from the feces that was given. So if I wanted to culture proprietary/trademarked/whatever strain 45-DX-L08V2 from a dog, I can do that after it's been administered. Bam.

What you have to keep in mind is that various strains/types have different properties/effects, so you need to choose based on what your specific goals are. However, in almost all cases a standard human supplement is fine.
