Product Description

Most fiber just passes through—ours goes to work. Our Prebiotic Fiber Complex is a 5-in-1 blend of clinically studied resistant starches and fibers that delivers 7g of dietary fiber in every unflavored scoop. Unlike basic soluble or insoluble fiber, this blend ferments slowly in your gut, producing butyrate and other short-chain fatty acids that feed the beneficial bacteria which help strengthen your gut and support a healthy microbiome. That same slow fermentation is what helps keep you fuller longer, curb appetite, and support satiety between meals. We combine 5,000mg of NuFiber Resistant Dextrin, 1,250mg of Solnul Resistant Potato Starch, 1,250mg of Oat Extract (70% beta glucans), 500mg of Green Banana Powder, and 500mg of Acacia Fiber for complete prebiotic coverage. Unflavored and easy to mix, it stirs into water, juice, or a smoothie. Each 9oz (255g) jar provides 30 servings, crafted in our own GMP & FDA-registered facility in the USA and 3rd-party tested for purity.

Top-Notch Quality I Can Trust!

Knowing that these products are 3rd party lab-tested in an FDA-registered facility gives me peace of mind. I'm always confident in what I'm putting into my body, and I feel the results daily—better immunity, more energy, and less stress. Nutri has gained a loyal customer in me.

Unbelievable Results!

I've tried many supplements before, but nothing compares to the impact of GlyNAC-ET. Within just a few weeks, I noticed improved focus, more energy, and a significant boost in overall well-being. The fact that it's 20x more bioavailable makes all the difference! Highly recommend it for anyone serious about their health.

Amazing Supplement

I've been using GlyNAC-ET for about two months, and it's made a huge difference in my energy levels and overall health. My workouts are stronger, and I feel more focused throughout the day. Plus, the lifetime satisfaction guarantee is such a great bonus. It's easily the best supplement I've ever used.

Frequently Asked Questions

What makes this different from psyllium or plain inulin?+
It uses five different fibers instead of one, chosen so they ferment at different rates along the colon. That spread is what produces steady short-chain fatty acid output and satiety without the sudden gas that a single fast-fermenting fiber like inulin can cause.
How much fiber do I get per scoop?+
7 grams of dietary fiber from 8.5 g of powder — 5,000 mg resistant dextrin, 1,250 mg Solnul resistant potato starch, 1,250 mg oat extract at 70% beta-glucans, 500 mg green banana powder and 500 mg acacia fiber.
When should I take it?+
Mix one scoop into 8-16 oz of any beverage before a meal, up to three times per day. Taking it before eating is what supports satiety. Stir it in slowly, as it can clump if dumped in all at once.
Will it cause bloating or gas?+
Far less than most fibers, because the blend is weighted toward slow, gentle fermenters like acacia and resistant dextrin. If you are new to fiber, start with half a scoop for the first week and increase from there.
Does it taste like anything?+
No. It is unflavored and unsweetened, so it disappears into water, juice, coffee or a smoothie without changing the taste.
How is this different from your GLP-1 Gut Support Fiber Boost?+
Same fiber blend, new label and packaging. If you have been buying GLP-1 Gut Support Fiber Boost, this is the same formula at the same 7 g serving.
