70% of your immune system comes from your gut.

But that’s not all — your gut also produces nearly all of your serotonin, expends up to 20% of your energy through digestion, regulates your metabolism, and so much more.*

Research shows that the gut is so core to different aspects of your health, that oftentimes the solution to a seemingly unrelated ailment can be found simply by improving gut health.

So whether you're suffering from mood, energy, immune system issues, or if you're simply experiencing digestive discomfort, prioritizing your gut health can yield major improvements.*

A fiber-rich plant-based diet provides a powerful foundation to gut health, but as with any aspect of health, regular attention and maintenance support healthy gut microbiota to keep your body feeling and performing its best.

For years, the go-to approach for gut support was a probiotic supplement, but the latest science highlights overwhelming concerns about the effectiveness of a general probiotic...

Probiotics: Health-promoting or a waste of money?

Adding a probiotic is the same as an alien bacterial strain to your gut microbiome, and studies show that the benefits of taking non-specific probiotics can wear off in as little as 3 weeks.*

While popular gut health products haven’t caught on, research now points towards prebiotic fibers and postbiotics — the beneficial end products of probiotics — as an effective aid to the high-fiber plant foods already in your diet.*

Gut Nurture’s innovative formula combines pre and postbiotics with health-promoting pre-fermented vitamins, plus ginger root and herbs to support powerful, whole-body health.*

Formulated in partnership with leading gut Registered Dietitians.

As practicing plant-based Registered Dietitian Nutritionists who specialize in integrative gut health, we work with thousands of clients who feel they can’t properly digest plant foods or experience issues related to gut health. This is especially true for those struggling with Irritable Bowel Syndrome (IBS) and/or Small Intestinal Bacterial Overgrowth (SIBO). We created Gut Nurture to help our patients bolster their microbes to find gut balance and optimal gut motility (movement).

Gut Nurture does not add massive strains of microbes like many probiotic supplements, but instead, it seeks to nurture the healthy microbes (gut bugs) so your gut microbiome can multiply and thrive.*

We have spent the last 14 months working hand-in-hand with Complement and patients to formulate a robust gut-supporting tool to relieve short-term discomfort and help establish a microbial environment that supports immune, energy, and long-term health.*

Bold ginger taste. Powerful gut solution

It’s a convenient way to easily nurture your healthy gut flora, day in and day out.

One teaspoon. Daily support

Ingredient highlights.

LBiome Postbiotic Lactobacillus

Instead of using less stable live probiotic strains which may not be compatible with your gut flora, Gut Nurture is built around a postbiotic — the stable, beneficial end product of probiotics that promotes the growth of healthy bacteria in your gut, supports the gut lining, nutrient absorption, and the immune system.*


A unique low-FODMAP, gluten-free prebiotic fiber to nourish your gut flora, and regulate digestion without the bloating and gas often caused by other prebiotic fibers.*

Pre-fermented B vitamins (B1-B5-B6)

Delivered in a pre-fermented, soy-free medium for increased bioavailability, the B vitamins in Gut Nurture help stimulate the growth of beneficial gut bacteria and assist with motility so food moves through your digestive tract easier.*


Delivered in a pre-fermented, soy-free medium for increased bioavailability, molybdenum plays a big part in the synthesis of enzymes that balance inflammation, control gas production, and reduce bloating.*

Ginger extract

The polyphenols and other compounds in ginger support microbiome diversity, assist with gastric motility, and have strong antioxidant and antiulcer properties.* Plus, the ginger in Gut Nurture provides a powerful taste!

Licorice Root Extract

Licorice has been used for centuries for its health properties, and to protect against digestive issues. Gut Nurture utilizes deglycyrrhizinated licorice extract to make it safe for daily consumption.*

Horse Chestnut

An herbal remedy with a rich history, horse chestnut can support gut comfort and imbalances.*




Empower your lifestyle.

Gut Nurture's easy to use mix makes it easy to support and build a healthier gut microbiome whether you're at home, traveling, or on-the-go.

Simply add a teaspoon to water, juice, or smoothie for powerful results.

Frequently bought together.

Fully transparent production.

Gut Nurture goes through a rigorous inspection process that includes third-party testing.

We want you to be certain that you are getting the highest quality nutrients, free from pollutants, heavy metals, and harmful pathogens — not to mention common allergens and artificial sweeteners, colors and flavors. That’s why every batch undergoes a rigorous series of tests to confirm that it contains all that it should — and nothing that it shouldn’t.

And we mean rigorous! We do as many as 19 different tests to ensure potency and safety. All this is done in pharmaceutical-grade facilities that are FDA Registered, and operate under cGMP standards.

Third-party tested.

This means that every ingredient and dosage on the back of the bag is verified by an independent lab. And just as important, the ingredients are tested for things like pesticides, E Coli, heavy metals, and salmonella.


We verify that all active ingredients on the label are present in the right amounts. But we're not satisfied with just meeting those - to ensure potency over time does not diminish, we aim for 10-20% over what the label states.

Heavy Metals

We take soil and water pollution seriously, especially since we design our products to help your body fight against it. Therefore, each batch gets tested for Arsenic, Cadmium, Lead and Mercury.


Our products are doubly protected by being produced in a certified facility, and tested for yeast and mold, and possible bacterial presence, such as Salmonella, E.coli and other coliforms.

100% Happy

We stand behind our products 100%. If you're not happy with the results, taste, or experience, we'll fix it.

100-Day Guarantee

You have a full 100 days after receiving your product to try it out and see if it's the right fit for you.

100% Money-Back

And if you don't love it within the first 100 days, we'll issue a full refund. No questions asked. No fine print. That's the Complement guarantee.

What are the nutrition facts?

suplement facts

How do you take Gut Nurture?

Adults and children over 12 can mix 1 level teaspoon (3 g) of Gut Nurture with 8oz of water (warm or cold) and drink. For optimal usage enjoy on an empty stomach. Gentle enough for people with GI issues and those following a low FODMAP diet. Can be taken by children under 12 y/o, after consulting with their care team.

Should I use Gut Nurture if I don’t have digestive issues?

Gut Nurture was formulated to be taken therapeutically for those with gut issues and for maintenance of gut health. It is always ideal to first consult with your care team.


Health always starts with food. This is why we recommend Gut Nurture as a complement to all of the amazing plant foods you eat & (hopefully) tolerate on a daily basis. Gut Nurture can also help with those struggling to add enough plant foods to their lifestyle due to existing gut issues like Irritable Bowel Syndrome (IBS), gut dysbiosis, and/or Small Intestinal Bacterial Overgrowth (SIBO).

Why is Gut Nurture better than probiotic supplements?

Gut Nurture was formulated to work with your gut microbiota (all the various microbes in your gut). Many times, non-specific probiotic supplements flood your gut microbiome with a tidal wave of a limited variety of bacteria, trying to force it into a certain balance. Newer studies are identifying that probiotic supplements should be taken in specific strains and quantities for your specific needs rather than a one-size-fits-all blanket approach. For daily gut health, on top of the prebiotic fiber you are eating, we formulated Gut Nurture to work with your gut to nurture what you already have and make it more robust and balanced over time.

Will Gut Nurture change my poops?

There are many reasons your stool (aka poop) can change in color, size, consistency, etc. With its added prebiotic fiber, compounds, and vitamins to help with gut motility (movement), Gut Nurture, all by itself with no other changes to your lifestyle could likely help with bowel movements, but it has not been proven to do so yet.

Will I immediately feel a difference?

Those who have taken Gut Nurture report an immediate relief of nausea, but overall Gut Nurture is designed to support your gut over time. There are ways to take specific therapeutic doses for those experiencing severe gut symptoms to alleviate symptoms such as bloat, malodorous gas, reflux, and more.* Work with a knowledgeable care team to guide you on this.

Should I take Gut Nurture daily or periodically?

We recommend you make Gut Nurture part of your morning/daily routine for daily gut love. Gut Nurture is the perfect tool to have in your home for daily use, when traveling, and times for those situations where your stomach might be upset or off balance.

What if I don’t like the taste?

Those who like or love ginger will likely enjoy the warming and soothing taste of Gut Nurture. If that is not you, you can also add Gut Nurture to a smoothie, smoothie bowl, or oats to give them a nice refreshing undertone without the direct ginger taste.

Why does Gut Nurture contain Stevia?

We wanted to be extremely inclusive when formulating Gut Nurture. Besides organic Stevia Leaf having a long history of medicinal benefits, it is also a naturally sweet tasting plant, like dates or fruit. While we love options like pure and whole date sugar as a sweetener, it can cause or worsen bloating. With Stevia showing medicinal properties, sourcing high quality/organic stevia, we felt confident that the benefits to all would be elevated by using this functional plant ingredient all while adding a sweet undertone.

When can I expect my order?

We aim to ship orders within 2 business days of purchase. In other words, our goal is to get Complement in your hands in just a few days!

Did you say 100-day guarantee?

Oh, there's a money-back guarantee alright! If you're not happy at any point in the first 100 days, we'll issue a full 100% money-back guarantee. No question. No fine print. Just contact our customer happiness team ( to start your return! (This goes for all Complement products, by the way.)

Marj H. (Gainesville, US)
Gut Nurture is the best thing

I’ve had gut/food intolerances for years. Using Gut Nurture has been the best thing for my gut. It’s given me high hopes that my gut can return to some normalcy. What a relief!

Robin D. (Oxford, US)
Gut Nuture - Pungent but Profound

Hold your nose when you open the bag! Very tart; I take it with my fermented apple cider vinegar in the morning. After three weeks, I can feel a noticeable difference in my gut behavior and food saturation. Something is finally working after numerous experiments with other prebiotics, probiotics, and related supplements. Will definitely buy again.

Alyssia C. (Austin, US)
Fabulous Product!

After the first day of taking the prebiotic powder, my tummy immediately felt better. I have had digestive issues for years and sensitivities to all kinds of foods. Even though it has only been a couple of weeks, some foods that normally irritate me don't do that anymore. I'm sure it's because the bacteria are healing and balancing my gut! It really is amazing and I'm especially pleased since I truly was skeptical! Thank you for all the hard work that went into developing this product -- for many of us, it truly, literally, is a lifesaver!

Simone W. (Colorado Springs, US)
Excellent for my gut and extra greens - What's not too love

Ever since changing my diet to plant based I have had trouble with bloating. Tried many pre- and probiotics to no avail. Enter Gut Nurture and finally my insides are happy. In addition I have ordered the Daily Greens and mix the two of them together for my morning elixir. Works great.

Martha J. (Black Mountain, US)
It works!

I have used the gut health for 3 weeks -I see a difference in my digestive tract -less bloating - less abdominal pain - and it tastes great
