How It Works

Supports Smoother Digestion*

Smooth, comfortable digestion requires a proper balance of “good” and “bad” bacteria in your gut. Our painstakingly perfected blend of 15 powerhouse probiotic strains delivers a whopping 30 billion Colony Forming Units (CFUs) in every capsule — which quickly go to work helping to bring balance to your gut.

Promotes Weight Management*

Some of the probiotics in our formula, such as Lactobacillus rhamnosus and Lactobacillus paracasei, have also been linked to weight management support.

Helps Reduce Gas & Bloating*

Fiber and other difficult-to-digest foods can cause embarrassing and uncomfortable issues like gas and bloating. Probiotics thrive on fiber, and can help reduce these unwanted digestive after-effects.

Why is Nucific Probiotic Complex different than other probiotics on the market?†*

Nucific Probiotic Complex is one of the most powerful probiotics on the market, and also one of the most diverse. Not only is each capsule filled with 30 billion CFUs** of good bacteria, but each capsule contains 15 different strains of probiotics.

Nucific Probiotic Complex even contains bile and acid resistant strains to help ensure that the good bacteria thrive in your system.

What are the ingredients in Nucific Probiotic Complex?

Who should use Nucific Probiotic Complex?†*

One of the best things about Nucific Probiotic Complex is that everyone can benefit from the power of probiotics. Whether you want help to lose weight, improve your digestion, or just have better energy and focus, Probiotic Complex can make a difference.

Given the prevalence of added sugars and artificial sweeteners and unnatural additives in the American diet, Nucific Probiotic Complex can help anyone digest more efficiently and get more from the food they eat.

How does Nucific Probiotic Complex work?†*

Your digestive system is home to billions of unique strains of bacteria, some of which help your system, and some of which don’t. When the bad bacteria in your body begin to outnumber the good, your digestive system can be thrown off balance, and any number of digestive issues can arise.

Because Nucific Probiotic Complex is packed with 30 billion CFU’s** (colony forming units) of good bacteria, it is designed to help your digestive system swing back into balance and help counteract the effects of bad bacteria.

**At time of manufacture.

How do I use Nucific Probiotic Complex?

To make the most of your probiotic routine, take one pill each day with a full glass of water. For best results take before or during the first meal of your day.

Does Nucific Probiotic Complex need to be refrigerated?

No- while many probiotics require refrigeration to keep the strains alive, Nucific Probiotic Complex is preserved using a flash-freezing technique that keeps it fresh – no refrigerator required. This means that Nucific Probiotic Complex can be kept for months, or even YEARS.

Can Nucific Probiotic Complex work for anyone?

As with any product, there are a select few people who don’t experience the wonderful effects of Nucific’s Probiotic Complex. If you’re one of the select few, or if you’re not happy with Nucific Probiotic Complex for any reason, we offer a 90-Day Money Back Guarantee. If you’re unhappy for any reason, get in touch with our friendly customer service team and we’ll make sure to return your purchase price.

Less bloating and gas


I never would have considered taking a probiotic before, but after a friend recommended it, I took the plunge. I have had such great relief with Nucific Probiotic Complex, the embarrassing abdominal discomfort has all but disappeared. This is the product I didn’t realize I needed.

Lost Weight-Feel Great


At the end of April, it will mark one year of using Nucific products. I have used many of the products and I like them all. I start every day with Bio-X4.*

It Works!!!

I’ve been taking the probiotic as well as a few other products of theirs and it really has made a tremendous difference. But I think the most important has been the probiotic because it has so many different strains. A lot of other probiotics out there have a lot fewer varieties of strains and I feel that this covers more ground and I feel that it works personally for me.*

Excellent Probiotic

Sometimes it is hard to recommend a specific probiotic […]. The high quality control and research behind Dr. Amy Lee‘s products make it easy for me to recommend the Nucific version without any reservations.*
