Gundry MD Bio Complete 3 Review: What Do Real Users Say?

I have struggled with an autoimmune issue called Proctitis, a bleeding inflammatory condition, for the past 5 years. My Gastroenterologist has had me in numerous medications such as Mesalamine and Hydrocortisone suppositories and enemas, and when those failed repeatedly, they even put me on Prednisone 40 mg graduating down over a period of 6 weeks until I was off the medicine, but even that didn’t clear up my condition.

Claudia Gerst

I see a lot of comments complaining about unpleasant symptoms while taking this, but the important thing to remember is the bad bacteria must be cleared out as the new good bacteria set up colonies. The sicker you are, the more bm’s you experience means your guy biome needs this rebalancing badly. This product has helped me and my son recover from a leaky gut syndrome, which had us both seriously ill and rapidly taking on new allergies. Doctors kept giving us antibiotics that were the exact opposite of what we needed to heal.I know everyone’s gut biome is unique but trust me when I say I have studied the crap (excuse the pun) out of this topic, reading medical journals and learning everything I can from functional medicine doctors. I also use food as medicine. You cannot continue eating trash food and expect probiotics to save the day. I highly recommend this product but get it on Dr. Gundry’s website. It is waaaaay cheaper than these prices.


I am not sure about this product yet. I have been using since last summer. I got a better price from the product’s actual website after my initial Amazon purchase. It helps me stay regular (I am in my 60’s) so I use it. As far as all the claims made go I am not sure but I also lost about 25 lbs. since taking this product (I was in possession of a “spare tire”) but I can’t promise the Bio-Complete caused this as I also made small dietary changes. However on the chance that this product did in fact cause the weight loss I shall continue to use it and if for no other reason than the fact that I have been “regular” since taking it then so be it.
