The Role of Prebiotic Inulin

The Role of Prebiotic Inulin

Each serving of IsoNatural includes inulin, a prebiotic fiber derived from chicory root. A randomized controlled trial by Guess et al. found that 30 g/day of inulin supplementation significantly reduced prospective food consumption (a marker of improved satiety) in adults with prediabetes over 18 weeks. The inulin group also experienced a 2.3% reduction in body weight during the weight-maintenance phase (weeks 9–18) and a 9.6% reduction in intrahepatocellular liver fat after just 9 weeks, compared with −0.5% in the placebo group.

I tried the unflavored, incredible. Cleanest and most comprehensive set of ingredients. Blends perfectly with no chalkiness. Add it to any shake and it won't affect the flavor. Price is right for the quality!

Taking nutritional profile, taste, and quality ingredients into consideration, this protein is pretty incredible! I’ve tried numerous brands of whey isolate that were “natural” before trying IsoNatural and none of them compare. I love that IsoNatural is sweetened with stevia and is low in carbs and fat. It’s very versatile for any health and fitness goals including those who need a whey isolate when they are prepping for fitness competitions! This will continue to be my go-to and a staple of mine for life! Thanks, ALLMAX!

I recently tried isonatural and I wish I would’ve tried it sooner! I was blown away at the taste. I love that it’s sweetened with stevia. This is a protein powder that I can keep in my diet for longer periods in prep due to how clean it is!

Isonatural is my favorite protein on and off of prep. The macros are amazing and the protein digests with no bloating or discomfort. It mixes great with nut milk and the stevia gives it the perfect balance of sweetness. Chocolate peanut butter forever!

best protein out there!
best protein I've ever had, dissolves perfectly, tastes great and has the more protein per serving than most on the market! Its low carb, low sodium and low fat, plus its made with stevia rather than garbage artificial sweeteners like every other protein. Plus its bakes well too, so you don't always have to make a shake to get in your protein! Highly recommended!

Good protein
I mainly use this for my daily smoothies. it doesn't have a really strong taste because it never overpowers my blueberries of bananas in my smoothie. It does add sweetness though so I don't have to put any other sweeteners.

Delicious with fresh/frozen blueberries! I would still drink it alone in a smoothie!

OK, so I think this IS a pure, high quality protein. Probably one of the best on the market. However, I have come to dislike it.
Every morning with breakfast I add it to a mug, then add organic unsweetened almond milk. The next step is mixing it. There lies the problem. A spoon stir - no go.
Just doesn't work. So I use what I've been using the last few years with all my various whey powders - a battery operated hand whisk beater.
A few seconds and BAM! - evenly mixed and consistent liquid whey drink. A real time saver.
So the problem with the Allmax, sans spoon, is that even 2 seconds with the beater and it turns to foam. Yes - I know, I know, someone is going to say I need to use a shaker container and wire wisk ball. But that's going to take some vigorous shaking to eliminate the lumps, and I know that I'm going to end up with foam again. Plus, I just don't have the time to mess around with all that and then deal with the cleaning.
There's something in the Allmax that just WANTS to foam up. So I end up just slugging down 6-8 oz. of gagging foam. Ugh!
I'm half done with my 2 lb. canister and can't wait to use it up. I'm going back to my previous whey powders

FAQ

IsoNatural is produced through cross-flow ultrafiltration and ion filtration, preserving native protein fractions. It contains no artificial sweeteners, colors, or flavors and includes prebiotic inulin for digestive support—distinguishing it from standard whey isolates that rely on synthetic sweetening systems.

Whey protein isolate is naturally very low in lactose due to the filtration process used to remove fat and carbohydrates. ALLMAX IsoNatural is 99% lactose-free, making it a suitable option for most individuals with lactose sensitivity.

Yes. IsoNatural is 99% lactose-free. Many dairy sensitivities stem from casein rather than whey, and because IsoNatural contains no casein protein, it is generally well tolerated by lactose-sensitive individuals.

Yes. IsoNatural is sweetened with stevia (Stevia rebaudiana leaf extract—no sucralose, no acesulfame potassium, no artificial sweeteners).

Inulin is a prebiotic fiber from chicory root. It supports healthy intestinal microflora, may improve satiety, and has been associated with modest reductions in body fat in clinical research.
