Bio Complete 3 Review: Is It Safe and Effective

By Rocklend Davis, Ph. D.

Bio Complete 3 is a dietary supplement containing a proprietary blend of prebiotics, probiotics, and postbiotics that is alleged to support gut health.

To date, most gut health research focuses on gut microbiota, which serves as the site that contains the highest number of bacteria.

Gut health is an extension of your immune system which employs a group of good cells/bacteria that work with the host to promote health.

Because Bio Complete 3 relies on probiotics, its group of bacteria helps develop the microorganisms in the gastrointestinal tract to promote balance and ensure optimal function.

Gundry MD claims that you will experience the following benefits with daily use of their dietary supplement:

  • Weight loss
  • Decrease levels of fatigue
  • Improved digestion
  • Decrease cravings
  • Immune system support

In this article, we will help you understand if there is any science backing these claims by reviewing the available research for the active ingredients.

Effectiveness of the Ingredients: Do They Support the Proposed Benefits?

A serving size is four capsules that contains a proprietary blend of ingredients:

  • Tributyrin (as CoreBiome ®): 1000 mg
  • Sunfiber®: 200 mg
  • Bacillus coagulans (ProDURA®) (2 billion CFU): 16 mg

According to the company, you need to take two capsules, which are absorbed quickly, twice per day before eating to experience benefits for your gut.

Below, we will go over the roles of these ingredients to see if the evidence supports the claimed benefits of Bio Complete 3:

Gas, Bloating, Diarrhea, and Constipation Relief

One of the many claims proposed by Gundry MD is the ability to reduce gas, bloating, diarrhea, and constipation.

Sunfiber® is a dietary fiber contained in the proprietary blend of Bio Complete 3.

Studies have found that a diet that is rich in dietary fiber can be an alternative to promote healthy weight while serving to promote a positive balance in the GI tract, and releasing and regulating hormones that associate with feelings of fullness.

A study demonstrated that Sunfiber®, when given in doses of 5 g/day, was able to normalize stool consistency and promote gut microbiota changes.

Bacillus coagulans is lactic acid and a probiotic culture that aids in the digestion of carbohydrates and proteins. B. coagulans can help to enhance the benefits of prebiotics to help promote the growth of more healthy gut bacteria.

B.coagulans was supplemented in 36 patients diagnosed with Irritable Bowel Syndrome. These patients experienced a significant decrease in clinical symptoms of bloating, diarrhea, vomiting, abdominal pain, and stool frequency.

Immune Support

Medical literature suggests that diets should include probiotics and prebiotics to enhance the immune response. When consumed in adequate amounts, probiotics and prebiotics may provide various health benefits.

A review was able to recently reveal the benefits of prebiotic and probiotics to enhance the immune response to seasonal influenza vaccine in healthy older adults. However, the amount in this study was more than double the amount contained in Bio Complete 3

The functional properties of dietary fibers, such as Sunfiber®, help protect against intestinal infections, activate bowel function, aid in nutrient digestion and absorption, and stimulate the immune response.

However, the dosage amount contained in the proprietary blend of Bio Complete 3 is much less than was used in the available literature, so it may not be adequate in providing the proposed benefits for immune support.

Weight Loss Aid and Decreased Cravings

Partially hydrolyzed guar gum (PHHG), now named Sunfiber®, is currently being used in various forms in beverages, food products, and medicinal foods.

Guar Gum is a dietary fiber and, due to its gel-forming capabilities, is involved with reducing macronutrient absorption and slow gastric emptiness.

Tributyrin is a compound of butyrate that is composed of a short-chain fatty acid that serves as a versatile molecule that is produced in the gut by fermenting dietary fiber and can be enriched in butter and other dairy products.

Butyrate has shown some promising effects in various diseases, including obesity, diabetes, inflammatory bowel disease, and colorectal cancer.

A study of Tributyrin suggests that oral administration of 2g/kg of tributyrin 3 times per week effectively protects against a diet-induced obesity and insulin resistance in mice.

The study showed that tributyrin was directly linked to the inhibition of the proinflammatory mediator production of the white blood cells, protecting skeletal muscle against insulin resistance.

Muscle and Joint Pain Relief

More research is required to determine the role of the proprietary blend of the ingredients in Bio Complete 3 for alleviating symptoms of achy muscle and joints.

However, an older study found a decrease in the inflammatory response. Improved muscle integrity was the most effective when B. coagulans were administered with hydroxymethyl butyrate.

Further, butyrate may serve a role in strengthening the intestinal barrier function.

A study done in both humans and mice produced data that suggests a preventative approach for inflammatory diseases by targeting impaired intestinal barrier function.

This study suggests that a dose of 1 g butyrate may be able to decrease the onset of arthritis from occurring, which is similar to the dosage that is contained in Bio Complete 3.

Summary
The benefits proposed by Gundry MD for the Bio Complete 3 may provide varying results due to dosages that are much less than the ones used in the available studies.

Safety

Tributyrin, when taken orally, can be safe at lower doses, but higher doses greater than 10 g/kg can be toxic. However, the dosage contained in Bio Complete 3 is only 1 g.

No adverse effects were noted when PHGG/Sunfiber® was provided in a study at a dose of 5 g/day in patients with chronic abdominal pain and IBS.

B. coagulans have a history of safe consumption in humans, as indicated from a review of toxicology testing studies.

When comparing dosage amounts, a study found that a B. coagulans dose of 2x10(9) CFU/day was found to be safe and effective in diarrhea-predominant irritable bowel syndrome for 90 days of supplementation.

It is best to take the Bio Complete 3 dietary supplement as indicated on Gundry MD's website. Dosing of any amount should never be increased.

While the safety profile for Bio Complete 3 is favorable, it may not address the underlying cause of your problem.

Therefore, you should seek your physician's opinion if you are experiencing issues affecting your quality of life.

Pricing and Return Policy

Alternatives to Bio Complete 3

TruBiotics by One A Day could be another option to support digestive and GI health.

TruBiotics offers 2 probiotic strains that have been studied extensively and it is reasonably priced when compared to the many probiotic supplements we have reviewed.

TruBiotics is available in-store or online through Walgreens, CVS, and Rite Aid. It is likely that you will save more with this product but you would be missing out on certain probiotic strains.

  • Walgreens: 30-count $18.99; 45-count $29.99
  • CVS: 30-count $21.99
  • Rite Aid: 3-count $14.99

The Bottom Line

Bio Complete 3 ingredients may offer support in weight management, though some studies used higher doses to achieve results.

The available research also supports the benefits of probiotics in relieving GI issues, with clinical trials being performed in humans.

To achieve the effects of weight loss, however, you should also include a daily routine exercise, and a well-balanced diet to achieve the same results.

Probiotics may offer benefits that support a variety of digestive and health-related issues. However, it is important to first identify the source of any symptoms you may be experiencing.

Further, the proprietary blend of probiotics in Bio Complete 3 has been studied extensively, especially as it pertains to improving the balance of good and bad bacteria that lines your GI tract.

However, because the proprietary blend of ingredients contained in Bio Complete 3 is smaller when compared to dosage in studies, it may not provide the proposed benefits.

5 STAR

By William C., Harleysville, PA, Verified Reviewer

Started taking this over 2 weeks ago, I had IBS and within 4 days it was gone. Last 2 weeks no more IBS. For me, Bio Complete 3 has to be the reason. I'll continue on this supplement and will look into Dr. Gundry's other products.

Bottom Line: Yes, I would recommend this to a friend

Definitely recommend Bio Complete 3

By Toni C., New Jersey, Verified Reviewer

I believe this product has helped me with bloating and constipation within the first week of taking. I have had these problems most of my life and tried other probiotics with no noticeable difference. I take 4 capsules at night before bed. Overall I do feel like I have more energy and less joint and muscle pain. I would definitely recommend this product. Works for me.

Bottom Line: Yes, I would recommend this to a friend

Bio Complete 3 works!

By Lauren S., Southern California, Verified Reviewer

I have been plagued with occasional IBS, constipation, loose stools, indigestion, and bloating over the past few years. The bloating was getting terrible this past year (2019). My doctor prescribed a probiotic and it helped some, but it didn't seem to be enough. Lately, I was buying Gas-X (simethicone) and taking an extra-strength pill nightly to ease my big, gassy belly. I read Dr. Gundry's information, and it made sense. I purchased a whole year's worth of Bio Complete 3, knowing I could return the balance of any unused product within 90 days if I did not feel it worked (but locking in the better bulk price). Let me tell you, IT DOES WORK. I have not taken a Gas-X pill for a month, since starting on the supplement, and my belly has reduced. I plan to keep up with the supplement (I started with one tablet week one and two, then graduated to two; I don't feel I need four so am staying on two a day for now) and add in some good health changes (diet and exercise) to make positive strides toward weight loss and feeling better. I'm 66 and feeling great. I recommend you try Bio Complete 3 if you have digestive trouble. It definitely is working for me.

Bio Complete 3 caused constipation and blockage

By Patricia I., Austin, TX, Verified Reviewer

I do not have any chronic gut problems but Dr. Gundy's video was so compelling I decided to give it a try to see if it helped with weight loss as promised. After taking the Bio Complete 3 as directed for 12 days, I noticed that I was feeling constipated, having chronic urges to try to have a BM, and having diarrhea along with the feeling of having a blockage that the loose stools were attempting to work their way around. I had such a hard time, that I purchased an enema, glycerin suppositories, and Seneca tea which finally assisted in clearing the blockage and returning to normal bowel movements. When I wrote to Dr. Gundy MD, I was shocked to receive a reply from a customer service rep who asked me the IDENTICAL QUESTIONS that I was asked a few months ago when I returned pro-biotics to DR. MARTY, a veterinarian who sells probiotics for dogs. My dog had a serious skin reaction to his probiotics. I am thinking the two companies are one and the same, and selling junk science to unsuspecting customers.

Bottom Line: No, I would not recommend this to a friend

Company Response from Gundry MD

Jan 21, 2020

Patricia, I'm very sorry that our Bio Complete 3 was not the right fit for you. We understand that everybody is different so we ask that our customers consult their physician prior to starting any new supplement. Those are not typical side effects so I have escalated your issue to our Customer Relations team. Please expect to hear back within 1-2 business days. With that said, I ask that you email me at aria@gundrymd.com as I'd be more than happy to issue you a full refund. In regards to Dr. Marty, we are in no way associated with that company. Thank you for leaving a review.

Starting the program

By Martin N., Boone County, KY, Verified Reviewer

My weight is 212lbs and I am in excellent health and shape. My issue is stubborn belly fat ugh. So here I am starting the program today. I have six bottles and I am taking 4 pills and drinking 9 oz 1 pt of water. So in 30 days I will revisit and tell you my progress. I measure 44" around my belly. With a 31" waist. So I am hoping I will reduce belly to 43 in a week then 42 in two days, 41 in two days. Wow, that means I need another .5 lb to drop a day to reach the 30-day goal. I have to admit this may take 2 to 3 months. We shall see. "Good luck chap," as the Brits would say.

Bottom Line: No, I would not recommend this to a friend

Works for me

By Lorrie L., Connecticut, Verified Reviewer

I’ve now completed 3 weeks at the recommended dosage. Two in the am and two in the pm. My BM is finally normal, meaning 2-3 times a day and feeling as if I’m emptying out. Prior to that I never felt like a completed BM. I suffered with bloating. Gas. Constipation. Feeling awful. I also suffer from Diverticulitis. I think I might have lost a couple of pounds but mostly just feel satisfied most of the time. I eat portion-controlled meals, drink a lot of water.

Bottom Line: Yes, I would recommend this to a friend

Love the product

By Verna H., Gasport, NY, Verified Reviewer

I have been using Bio Complete now for a couple of weeks. I am 85 years old and had a lifetime of constipation and bowel problems. I am doing great, feel so much better and have a granddaughter with the same problem. She loves it too. So I am going to order 6 bottles and we are both going to stay happy. Thank you Dr. Gundry.

SO FAR GREAT!

By Gerrette B., California, Verified Reviewer

I just started taking Bio Complete (4 days), so this review may be a little early to complete (hence the 4 stars instead of 5), BUT I felt compelled to write this because the change in my BM’s and overall energy is remarkable in just a few days. Prior to this I was taking probiotics recommended by my local health store and have for years suffered from constipation, bloating, hemorrhoids, and overall gut problems. I have been taking two a day, one in the early AM and one before bedtime. Feeling great and BM’s are easy, painless, and back to daily!

Bio Complete 3

By Marsha F., Myrtle Beach, SC, Verified Reviewer

I have been using Bio Complete 3 for 3.5 weeks. There is no doubt that I am having less constipation, which is great! However, my concern is that the color of my bowels has turned yellow. This has me concerned. The color is usually brown. I stopped taking the Bio Complete 3 for 2 days and although slightly constipated (again) the color returned to brown. I have read that yellow bowel color is not good. I'd like to know if anyone else has had this problem and if after time this goes away.

Bottom Line: No, I would not recommend this to a friend

Company Response from Gundry MD

Mar 12, 2020

Marsha, as always, we ask that our customers consult their physicians prior to starting any new supplement to ensure that it is the right fit. With that said, I suggest that you stop taking Bio Complete 3 until you've done so. You can find a full list of ingredients on our official website. If you find that Bio Complete 3 is not the product for you, please email me at aria@gundrymd.com and I'd be more than happy to assist you with a full refund.

Feeling the difference

By Keith B., Michigan, Verified Reviewer

I want to start by saying I work in the health care field and I understand that majority of the medical community treats symptoms not dysfunctions. Therefore, I am very skeptical of many products and understand it's a billion-dollar industry, in which everyone is trying to make a "buck." After researching the claims Dr. Gundry teaches us, I was convinced and had to buy his book "The Plant Paradox" and the cookbook that goes with it. He hits every level of commonsense with his explanations. I eventually had to try the product Bio Complete 3. I have to admit, everything he claims this product does; more energy, less foggy brain, regular bowel movements, etc., is true. My gut feels better and I have lost 5-8 lbs, and have only been using this product for roughly 2-3 weeks. I did not buy Bio Complete 3 to lose weight, I just wanted to have a normal gut. I will be using this product to help bridge my "feeling better" to improving my family diet (hard to convince a 4-year-old that Kraft Mac and Cheese is terrible).

I recommend this product and get Dr. Gundry's book, "The Plant Paradox."

Bottom Line: Yes, I would recommend this to a friend
