A Necessary Food Source for my good bacteria (Probiotics)
I take it as a Food Source for my Probiotics. If you are lucky enough, and your Probiotics actually survive beyond your stomach (Certain Strains survive the journey better than others) - and they actually make it into your intestinal tracts - you must feed this good bacteria what they like (XOS / FOS and other Fibers) - if it is to survive and thrive. So unable to really tell if my Bacilus Subtilis & Bacilus Coagulans (and others) are enjoying and thriving by feeding on this particular XOS. No ill affects for me - so will continue to take my good bacteria out for dinner. Good Value. for the quantity of XOS content. Just in case my bacteria are finicky eaters - I alternate this with a another good value fiber capsule (TRTL Psyllium Husk Brand).

This might be the best value XOS on Amazon. It comes as a powder in a cellulose capsule (which is excellent when taking as a supplement but a bit fiddley for making l reuteri yoghurt)(which, hot tip for the recipe, ten caps is one tablespoon of powder) that you’d think would be more exxy than the powder only product, but this bad boy, gram for gram, dose for dose, still wallops even the budget brands selling it as a powder. Highly recommend 👍🏻

For some reason inulin has never made much of an impact on my gut. I recently read about Xylo oligosaccharide as a prebiotic food to increase the good bacteria. I have a problem producing good bacteria as I have recently discovered I have small intestine bacterial over growth. So I bought this to try and can feel the difference when taken with a good probiotic.

These arrive in a HDPE bottle that is recyclable. There are 120 capsules in the container which has a safety/tamper seal & bsomething I've not seen in a pill bottle in years; a cotton-wool ball to stop the contents moving about. There seems to be some confusion as to dosage though! One section says; "Serving size: 2 vcaps Servings per container: 60" Then directly below this it says; "...take one (1) tablet daily..." Now I don't imagine taking a little extra prebiotic a day will cause any harm, but I seriously dislike conflicting information as to dosage on a pill bottle. Hence why I knocked off a star. There are the usual warnings about for adults only & don't take if pregnant & to speak to a medical practitioner before starting them Plus to stop taking them if you have any adverse reactions, all pretty boiler plate stuff on a supplement bottle. There are" No Artificial Colour, Flavor or Sweetener, No Preservatives, No Sugar, No Starch, No Corn, No Soy, No Egg, No Lactose, No Gluten, No Wheat, No Yeast, No Fish" & the capsules are made of vegetable cellulose; though it doesn't categorically state if the capsules are vegetarian or vegan. The product descriptions says "Best Naturals Prebiotics Fiber XOS (Xylo Oligosaccharide) 1400mg serving 120 Veg Capsules" & the ingredient list is "Prebiotic Fiber, Vegetable Stearate, Silica, Vegetable Cellulose (Capsule)" I have to take a large amount of tablets every day & some of them cause upset to my digestive system, so I find taking these in conjunction with probiotics & a healthy diet helps me not feel nauseous & my digestive process working fine. ~ They don't have any real aftertaste after swallowing & no strong odour from the bottle. They are priced at £14.99 at the moment which may seem slightly pricey but it works out to 12½p per day for 3 months supply if you are taking one a day as I am, I'm happy to spend that to keep me healthy & not feeling awful every morning when I take my tablets.
