    Not atm. I may try an individual Bifido. The higher potency multi-bug probiotics make me feel sick.

    I'm also combining RS with psyllium, and will include GOS (bimuno.com) soon. Scroll back in this thread for rationale.

    Have I misunderstood the role of psyllium? I had thought it was just a bulking agent. Is that getting fermented too?

    I don't know, tbh. I've read various sources which claim that it is, that it isn't, or that it is but very poorly.

    Thanks for posting that. Very interesting read however the guy's writing style is a bit hard to follow. The huge font on his blog dosen't help. I am now rather confused as to what the precise benefit of RS is...he keeps going back and forth.

    So it seems bifido are NOT SCFA producers....

    Is the primary benefit of RS then instead the increase in "Roseburia intestinalis" and "Eubacterium rectale" which create all the SCFA's such as butyrate?

    RS's primary benefit then appears to be that it feeds/help bifido which then "cross-feed" the actual SCFA producers. A chain-reaction.

    Well, RS seems to produces the most butyrate of any fermentable fiber in vivo...

    http://forums.phoenixrising.me/inde...ve-been-looking-for.26976/page-23#post-428855

    So, my guess is that RS gets fermented by a lot of different gut bugs. I have a feeling at this point nobody really knows exactly how it's able to produce so much butyrate.

    I think this is a good example why in vitro will give you a "better" result in terms of butyrate production specificity because it rules out confounding variables of in vivo conditions where cross-feeding occurs which can lead to erroneous cause and effect conclusions.

    It's the clostrida group that does the actual SCFA production, but gets its materials from the bifido which gets them from the RS.

    also:

    "It isn’t as simple as feeding one species a particular substrate, and one species another. In the case of bifidobacteria — who produce lactate and also acetate — we know that certain commensal butyrate producers consume those end products (lactate and acetate) and turn around to produce butyrate. Bifidobacteria also initiate the breakdown of and then release certain fermentable fibers that are then made available to butyrate producers. (More on these two cross feeding mechanisms here: http://aem.asm.org/content/72/5/3593 .)" (source)

    Vegas was interested in procuring some Bifidobacterium adolescentis.... i think I know why now.

    RS3 can work for butyric and Bifidobacterium adolescentis.

    I suppose you can obtain lotus seed from an asian grocery, but there are probably easier and/or healthier RS3 alternatives (rice?)

    Basic question: I have been trying 1 teaspoon of the Bob's Red Mill version for about 5 days but it is definitely causing constipation. My "work-around" is extra magnesium. My experiment the first day with taking an extra teaspoon later gave a lot of gut distress so I am planning to move up slowly.

    Are others having this problem and, if so, does it resolve at higher doses or get worse?

    Thanks,
    Sushi

    I will probably be adding glucomannan from konjac root soon once it arrives from Amazon. It is a soluble fiber which is supposed to be fermented by bifidobacteria and lactobacilli.

    Mine got better when l increased. I am now one heaped Tbsp which is 30gms not 15, l can't understand why it is said to be 15gms? Very smooth bm's now. I also started Mutaflor today which my doc advised.

    Does anyone know if this potato flour from Holland and Barrett is RS? I plan on going to Waitrose today to buy the Kockens stuff and these two shops are really near each other so I thought I'd see about buying both kinds to try them out.

    It's got 77g carbs per 100g so it looks like it's the stuff - if it sinks to the bottom in water after you've stirred it in that's another indication. I use the Kockens product (some Swedish guy checked with them about their process and it's RS).

    First of all I went to Waitrose and couldn't find it anywhere, looked in all the sections I could think of, baking, gravy, "free from."

    So I popped along to H&B and bought the potato flour and it looks like you might be right. It sank to the bottom of the glass. :)

    Are these products organic like Bob's Mill? Thanks.

    I can't see anything that indicates that the Kockens one is (it's in Swedish or something, though!).
