Sunfiber & Acacia Fiber

Sunfiber & Acacia Fiber

7.4 oz / 210 g Unflavored Powder

Most fiber supplements work too aggressively, fermenting fast in the colon and causing bloating, gas & discomfort. This world-first blend of two slow fermenting, low FODMAP, soluble fibers works gently to nourish good bacteria & support normal bowel movements – without the upset.† Exclusively made with organic-grade Sunfiber (PHGG - partially hydrolyzed guar gum) & Acacia fiber, and 3rd party tested in the USA, this is the gold standard in prebiotic fiber support.

What Makes Essential Stacks Different

What Makes Us Different

Most supplement companies cut corners where you can't see - using overseas manufacturing, skipping independent testing and loading products with gut-irritating fillers. We take the harder, more expensive path because your gut health deserves better than “industry-standard”.

Gut health.

I have a condition called rosacea, brought on by candita overgrowth. This product really helps to balance my gut bacteria and keep my condition at bay. Great product.

Now a part of my daily routine

This product keeps my lower gut regular and consistent after a lifetime of sensitivity to food. It’s a life saver. I mix half a teaspoon into my morning glass of water with no taste, and later again in the afternoon. I’m a small person so you need to decide for yourself how much you need. I will use this stuff forever.

It works really well.

I have Rosacea, which is essentially a gut problem. Friendly Prebiotics along with other ES supplements and diet has helped tremendously to clear up the symptoms. It's a great product. Highly recommended.

Frequently Asked Questions

  • What does Sunfiber & Acacia Fiber do for my gut health?

    This world-first blend of two slow-fermenting, low FODMAP soluble fibers gently nourishes good bacteria and supports normal bowel movements without the bloating, gas, and discomfort that other fiber supplements may cause.†

  • How is this different from other fiber supplements?

    Most fiber supplements work too aggressively, fermenting fast in the colon and causing digestive upset. Our Sunfiber and Acacia fiber ferment slowly and gently, making this the gold standard in prebiotic fiber support.†

  • How do I take Sunfiber & Acacia Fiber?

    Mix 1 scoop (2.5g) with 8 ounces of water or your favorite beverage, 1-3 times daily. Start slow with 1/2 scoop daily for the first two weeks to let your digestive system adapt, then gradually increase as needed.

  • Why do I need to start with a smaller dose?

    Even gentle fibers need time for your gut bacteria to adjust. Starting with 1/2 scoop for two weeks prevents any initial digestive discomfort and allows your microbiome to gradually adapt to the increased prebiotic support.†

  • What makes this formulation special?

    We combine two complementary fibers: Sunfiber (partially hydrolyzed guar gum) and Acacia fiber, both organic-grade and low FODMAP. This dual-fiber approach provides more complete prebiotic support than single-fiber supplements.†

  • Is this tested and free from allergens?

    Yes, it is independently tested and verified free from gluten, dairy, soy, and casein. It's also non-GMO and vegan.

  • Do you offer a money-back guarantee?

    60-day money-back guarantee, even if you've used the entire bottle. No questions asked. Applies to 1 bottle on your first order only.
