How It Works

Supports Smoother Digestion*

GI Complex combines powerful amino acids — L-Glutamine, N-Acetyl D-Glucosamine, and Zinc L-Carnosine. Together, these compounds work to help soothe your gut lining — so you can experience easier digestion, regular bowel movements, better nutrient absorption.

We also added Citrus Pectin Fiber to feed your good bacteria, promote smoother digestion, and help remove waste from your system quickly & efficiently.

Reduces Gas & Bloating*

Licorice Root helps alleviate symptoms of digestive discomfort — like gas and bloating — so you can enjoy your favorite foods again.

Promotes Weight Management*

Slippery Elm Bark has been shown in scientific studies to support a healthy gut lining, ease digestive discomfort, and even promote weight loss.

Boosts Energy Levels*

By supporting a healthy gut lining, GI Complex helps you GAIN back your youthful energy — and give you the power to meet all your weight and health goals. This powerful ingredient blend works to help optimize your digestion and boost nutrient absorption — so you’re “fueled up” for the entire day, no matter what’s on the menu.

*All individuals are unique. Your results can and will vary.

Feel free to experiment with adding it to other beverages — like smoothies, sparkling water, or your favorite juice.

What are the ingredients in GI Complex?

Is GI Complex tested for purity and quality?

Absolutely. We test all of our formulas under strict guidelines at an independent, 3rd-party facility. However, as a physician I recommend consulting with your own doctor before starting this (or any) new health program.

What if it doesn’t work for me? Is there a guarantee?

Every individual body is different. So if this formula doesn’t 100% meet your expectations, rest assured we’ve got you covered. Your order of GI Complex is covered by our “Feel Slimmer Or It’s Free” Guarantee. That means you can use up the entire jar — and if you’re unhappy for any reason, just send it back within 90 days. We’ll happily refund your purchase price, no questions asked.

Is GI Complex sold in stores?

No. Because GI Complex is brand new, it’s not available in stores. Currently, Nucific is the only company selling GI Complex. Amazon and other online distributors do not carry this product.

GI Complex for Healing Gut Issues

I have my naturopath review and muscle test everything that I use for supplements before I commit to using them. He was impressed with the results from the Digestive Enzyme and the Bio X-4 which I have been taking for quite some time now. When he saw the GI Complex online, he was the one that said I should definitely be on it. The line up of ingredients are excellent. I have only been using it for one month so far, but love the taste and am looking forward to more positive results.

Tastes great and helps w digestion

I thought to add this to my Biox4 routine and it mixes easily with water and tastes great! Allows me to have better digestion and just like fiber lets you go regularly and decreases bloating. Its been working great for me 🙂

Good product

I am very pleased with the GI complex. I wasn’t so sure about it when I first ordered it. I didn’t care for the taste either. But I was so impressed with Bio X4 that I persevered and now after a month later I’ve gotten used to the taste and it works so well that I don’t miss a day without drinking it.
