What is Inulin?

Inulin is a naturally occurring soluble fiber that is found in plants and is also known as a fructooligosaccharide (FOS). Inulin is a prebiotic, as the natural bacteria found in the lower gut converts it into healthy fatty acids. Inulin is naturally sweet and has about 10% the sweetness of sugar/sucrose. It is also often used as a flour substitute in baked goods as well as a fat substitute in margarine. Inulin is naturally found in foods such as onions, garlic, bananas and wheat. This particular Inulin supplement is derived from artichoke.


Inulin is a natural soluble fiber that contributes to a healthy digestive system and supports the colon. When taken in conjunction with a healthy diet & exercise, Inulin may also aid in maintaining healthy weight and glucose levels in already healthy individuals.

I recommend this product

I like it a lot

great, cept for all the pooting! hehehe



I never expected to find the perfect combination of pretty much everything in one supplement. Inulin is pure fiber, so it keeps blood sugar level (keeps is from getting too low OR too high), and it also fills you up. It's prebiotic, which means it's good for helping good bacteria grow. It's safe for pregnant women or breastfeeding mothers. And it tastes EXACTLY LIKE SUGAR! Best supplement ever. I just bought an enormous 25-pound bag from BulkSupplements, and I wouldn't be surprised if I buy another one in the next year.

Such a simple solution to digestive issues

I've had digestive issues for several years that probiotics should help -- only they weren't working the way they should. Acidophilus, saccharomyces boulardii -- I've tried a number of them. They helped some, but not enough. And here's the funny thing: I'd heard about "prebiotics" being necessary too, but since I'm vegan, I got plenty of them in my diet naturally, or so I thought. Anyway, in desperation, I tried powdered inulin. And still took the sacccharomyces and acidophilus. To be honest, I wasn't expecting much because of the prebiotics I already had in the food I ate. But this eased symptoms right away. An almost immediate decrease in trips to the bathroom and the urgency I had to get there ;) within a couple of days. All from a simple "sugar" that feeds good bacteria. I guess it's the concentration of the inulin that made the difference.


sweet and satisfying

Inulin is a prebiotic that is naturally sweet. Not quite as sweet as sugar, but sweet enough. I love using it to make home-made yogurt as well as a sugar substitute. It's a fiber, so if you aren't used to eating fiber, take it slow. There are tons of studies showing we don't get enough fiber in our diet and there are many health benefits, especially for our gut flora. Just do a bit of research and you'll see why I love this stuff.



I cannot describe how delighted I am to have discovered inulin powder, and the price at BulkSupplements is excellent (which is why I purchased it here). It tastes exactly like sugar, which makes it really, really delicious to eat a spoonful of. It also seems to work perfectly in baked goods as a sugar substitute -- and there's no sugar in it, OR anything artificial, just pure fiber. It's like, seriously, are there any downsides to doing this?! The only downside I can find is that you shouldn't eat too much fiber at once if you're not used to it, because too much fiber isn't great for your body. (Too little fiber, by the way, is worse.) But . . . seriously, too much sugar is far worse for you, and this seems to be the perfect sugar substitute because it's actually healthy. I notice the same effects from eating inulin as I do from eating psyllium husk: eating too much will cause loose bowels and intestinal discomfort. Eating the right amount causes stools to be soft without being loose and prevents constipation. Drinking too little water with it will cause dehydration and accompanying headaches. Drinking enough water with it easily prevents that. Additionally, fiber stabilizes blood sugar, which means that when I take inulin, I get filled up quickly, and I don't have an appetite for longer, which is great. By contrast, eating sugar gives me an instant sugar rush and then a sugar crash, and then I want to snack on everything in sight. Inulin tastes exactly the same as sugar, and has almost exactly the same texture, and yet it's better in every way. I can't even tell you how delighted this makes me. Inulin for the win! Yay!
