Gundry MD® Bio Complete 3™ Benefits†*

Prebiotics are the dietary fiber that feeds probiotics (aka your good gut bacteria). Probiotics help you repopulate your gut with beneficial bacteria. Postbiotics, the essential nutrients and fatty acids left behind by the two, may help support the walls of the gut lining, for less digestive upset.2

The basic concept is that using a supplement that contains prebiotics, probiotics, and postbiotics might help to alter the gut microbiome of the digestive system in a beneficial way. A postbiotic is a substance released when a probiotic consumes a prebiotic. They can exert a beneficial effect on the host — that’s you.3†

The Bio Complete 3™ formula may help promote a feeling of focus and alertness throughout your day. Gundry MD company researchers wanted to help you maintain a healthy metabolism well-into your 50s and beyond.

Moreover, the team behind Bio Complete 3™ dedicated themselves to finding the best beneficial ingredients. And, if you’re worried about whether they really work, read the overwhelmingly positive Bio Complete 3™ reviews on the Gundry MD website.

Looking hopeful

I have been taking Bio Complete 3 for three weeks and so far the results are promising although I havent noticed a drop in weight or belly fat. My digestion feels more settled and my energy levels are improving. I intend to complete my three-month course and then review my progress.

Bio-3 Review

This product seems to be making a difference, but after only two weeks, I feel it is still too early to make a judgement call. So far, so good and some improvement noted. Definitely try it.

Stopped after a year and came back

I took this for over a year and enjoyed it. My bloat was gone and over all felt healthier it. I stopped to try another one and had to come back because my hormonal acne is coming back. So all that time my skin was better because of bio complete 3.

Good product

Ordered several bottles through promotion and shared with family members. I've been taking for about a month now and noticed changes after the 1st week. My cravings for sweets has reduced significantly and regular bowel movements. I've recently added the 24 strain probiotic and taking it daily too.

Bio Complete 3

I have been using this product for a about a month. So Far so good. It is not giving me any problems thus far. My concern is about leaky gut. This is the purpose for purchasing this product.

C-Diff recovery

I was taking Vital Reds and the new capsules arrived as I finished VR's. I continue daily taking the capsules. I have two more capsules - bottles. I am sticking with a bland diet with protein, bananas, rice chex, no dairy, no sugar, and limit caffeine coffee to one in the morning or I get headaches. Any other coffee is decaf. Can eat avacodo, swt potato and a few white potatoes, asparagus but afraid of fruit and all the other vegetable I Love. I expect to add more foods as I continue your capsules. I do not eat fried foods i. e. French fries. Thank you

Flatter stomach

In a couple of days, my stomach was flatter, and the pre-, pro, and post biotics were working wonders

Kim, on 03-14-2023

I don't get all bloated anymore but I'm only taking one a day so my husband can do it I can't afford it for both of us

Better rest

Sleeping better at night and deeper rest For the past 6 weeks. Less gas experienced both starch and gastrointestinal

Jr, on 03-02-2023

I have been using this product for about 3 weeks now. It has definitely made me more regular but I've had some other effects. For the first couple of weeks my skin broke out ( one large pimple every few days, not mass breakouts). This seems to have settled. Is this normal when first using the product?
