Bio Complete 3 Review: A Unique Probiotic for Gut Health (2024)

What Bio Complete 3 Gets Right

• Offers probiotics, prebiotics, and postbiotics in one supplement.
• The supplement contains ingredients that have been clinically studied and shown to be effective in improving gut health.
• Has a 90-day money-back guarantee, even on opened products.

Important Considerations

• The brand does not list probiotic CFUs per serving, making it impossible to know if the product contains an effective dose.
• Other key ingredients have promising benefits but are in smaller amounts than what was studied, so they may be underdosed.
• You must use this product consistently to see results, so consider the ongoing monthly costs.
• Bio Complete 3 is more expensive than its competitors. But if using the subscription service and buying in bulk, the cost is similar to alternative products.
• Having to take four capsules a day may not be appealing to some.

Bio Complete 3 at a Glance

Bio Complete 3 from GundryMD is a probiotic supplement created by Dr. Steven Gundry, a cardiac surgeon with over 30 years of experience. It is uniquely designed to support gut health by providing a blend of research-backed probiotics, prebiotics, and postbiotics.

One of the keys to optimal health lives in our gut. Research shows that the microbes living in our intestines interact significantly with our mind, heart, and overall wellness. Ensuring optimal gut health is essential for anyone wanting to take steps towards improving their overall health.

Bio Complete 3 aims to promote total body wellness by offering a comprehensive product to improve your gut health.

How to Take It

The recommended dosage for Bio Complete 3 is two capsules twice per day, taken before meals. For optimal benefits, it is recommended to take this product daily.

Tip: Combine Bio Complete 3 with a well-balanced diet and healthy lifestyle. Include plenty of fiber-rich foods such as whole grains, fruits, and vegetables. Add probiotic-containing foods such as kefir, Greek yogurt, and fermented vegetables to help maintain optimal gut health.

The Cost Is Not Cheap

Bio Complete 3 is not sold in stores and must be purchased directly online from the Gundry MD brand.

Supplements containing prebiotics, probiotics, and postbiotics are typically more expensive than products that only offer probiotics. Still, the one-time purchase price of Bio Complete 3 is more expensive than its competitors. However, buying it through a subscription makes a meaningful difference and makes the price comparable to alternatives.

The brand offers a friendly 90-day money-back guarantee, including for opened products. If you are not fully satisfied with your purchase, you may request a refund minus the shipping cost.

Research Behind the Benefits of Bio Complete 3

Although Bio Complete 3 has not been tested as a whole, the supplement contains probiotics, prebiotics, and postbiotics that may help support your gut health and overall wellness. However, it’s important to remember that while certain ingredients produced some early promising results, they are used in smaller amounts in this supplement.

Additionally, the brand does not disclose how many CFUs are available per serving for Bacillus coagulans, which would be helpful considering there is solid research behind this probiotic strain.

Note: CFU stands for Colony Forming Units, representing the number of live and active microorganisms in one serving of a probiotic supplement.

Below we’ll break down the research behind ingredients and their possible roles in providing potential benefits.

Gut Health

Probiotic supplementation in healthy adults may improve the concentration of beneficial gut bacteria, leading to improved digestion, better bowel movements, and less gas and bloating.(1)

Research has found that the probiotic bacillus coagulans can withstand the stomach’s acidic environment to reach the intestine where it grows. Once B. coagulans is active in the small intestine, it will improve the groups of beneficial bacteria, resulting in better digestion, less abdominal pain, and less bloat.(2)

Bio Complete 3 also includes SunFiber, a prebiotic that positively affects digestive health and promotes better stool frequency and consistency. However, studies show that while it is promising, the amount of SunFiber in this supplement is significantly smaller than what was researched.(3)

Energy Support

Studies show that healthy bacteria in the gut are correlated with improved energy. Specifically, the probiotic B. coagulans used in Bio Complete 3 has been shown to aid in the digestion of carbohydrates and protein, allowing the body to utilize nutrients better, which may lead to improved energy.(4, 5)

Food Cravings

Studies have shown that having a positive balance of gut bacteria may lead to fewer cravings and food addictions.(6, 7)

Specifically, SunFiber™ is a soluble dietary fiber made from hydrolyzed guar gum that provides a feeling of fullness, possibly reducing cravings. However, the amount in Bio Complete 3 appears smaller than what was studied.(8)

Weight Management

Research has shown B. coagulans may play a role in the digestion of carbohydrates and protein, maximizing the benefits of protein supplementation. Optimal protein intake and absorption are necessary for weight loss.(5, 9)

Additionally, as mentioned earlier, SubFiber, a soluble fiber, may increase feelings of fullness by improving the good bacteria in your gut and overall digestion, resulting in healthy weight support.(7)

Finally, this supplement also contains Tributyrin, which studies show may play a small role in improving fat metabolism. However, more human research is needed as some studies have been done on animals.(10, 11)

Consider Safety Before Taking This Supplement

Probiotics such as Bio Complete 3 are generally safe for healthy adults.

While not widely reported, some people may deal with mild side effects from most probiotic supplements, such as diarrhea and bloat, especially when you first start taking them.

However, caution should be used with taking probiotics if:

• You have a weakened immune system, a critical illness, or have recently had surgery. This is due to a possible risk of infection in certain people.(12, 13)
• You suffer from GI conditions. Before beginning supplementation, you should review with your physician, as some probiotics may worsen your condition.
• You are pregnant or nursing. Bio Complete 3 is not intended for pregnant or nursing individuals without doctor supervision.

Bio Complete 3 is gluten-free, vegetarian, and free of added sugars. It has also been third-party tested to ensure purity and potency.

How Bio Complete 3 Compares to Alternatives

Bio Complete 3 is unique by containing prebiotics, probiotics, and postbiotics in its formula. Not many brands offer this combination of ingredients.

The more common ones are synbiotics, which refer to products that contain both prebiotics and probiotics. Seed Daily Synbiotic and Ritual Synbiotic+ are the two best brands we evaluated. Here’s how Bio Complete 3 compares to them.
