My own experience with phages:

> Re "Floraphage" sold as a prebiotic:
>
> Interesting... I didn't expect this to do anything for some reason, but I bought it anyway since I was out of things to try and it seems quite effective for my IBS-D, CFS, and soil-bacteria issues.
>
> Edit: hmm not sure about this actually. Effects either wore off fast, or were due to something else, or require an accompanying probiotic. Currently taking it with prephage. Will update.
>
> Edit2: Seems to only work as a combo with another probiotic. Prephage + floraphage + b.coagulans ProDura is helping a lot. Prephage might be the biggest help.
>
> Edit3: It seems to matter very much which meal & probiotics I take it with. When I take it in the same meal as culturelle & biogaia gastrus it seems to inhibit them, but when taken in a separate meal it does not. Interesting considering the claim is that they do the opposite - boost the effects of probiotics. They probably boost certain kinds/strains only.

>I was hoping that since phages work similar to antibiotics I wouldn't have to keep taking them, but with the kind in these US products it seems you do have to take them indefinitely.

> I found some other phage products by searching "phage" on Amazon. One is "TetraPhage", and the other is "PreforPro", but they both seem to have the same phages: LH01 - Myoviridae; LL5 - Siphorviridae; T4D - Myoviridae; LL12 - Myoviridae.

> "PreforPro" in this product seems to be the cheapest: https://www.amazon.com/Prebiotics-PreforPro-Supplement-spore-forming-bacteriophage/dp/B01NAE7J7B - $17 for 60c
>
> It also contains: DE111 TM (Bacillus subtilis), Bacillus coagulants, Lactobacillus acidophilus, Bifidobacterium lactis
>
> This one has just the phages (TetraPhage): https://www.amazon.com/Nutrivee-Advanced-Prebiotic-Supports-Beneficial/dp/B01CTBDDWY - but it's more expensive than the above product. $11 for 30c Now $18 for 60c.

> Floraphage is the same stuff as well. From their website: "Floraphage is a blend of bacteriophage species". They don't name the species on their site but I emailed them about it and they confirmed these are the only phages currently allowed for supplement products. All phage products in the US contain the same 4 phages.
