bio x4 reviews


I cannot say enough good about this probiotic. It’s basically saved my life. Or the constipation I dealt with for years from taking opioids. I tried every medication they made and none of them worked. But when I started taking a bio X4, it immediately helped me and so far has continued to help me. I am on my third bottle. My only hope is that it continues to work as well as it does.

Better Digestion, No More Nasal Issues

I’ve been on the formula for several months. Sometimes I forget to take it before meals but I still am experiencing better health. No more post-nasal drip, which I had for six years, and I have fewer cravings for refined carbohydrates. I’ve lost about 8 pounds even though I didn’t take it for that reason.

Excellent If You Stick With It!

I’ve been using Bio X for 3 years now. It immediately lowered cravings for bread and sweets. After adopting a mostly vegan diet I’ve lost 30 pounds over 3 years. Swimming three times a week has also helped! Thanks, Dr. Lee for this fantastic product. I’m 67 and retired having more time now to devote to my health and wellness. I take it 3x day.

Fix your gut

I have been taking Bio-X4 for several years now. However the first year I didn’t pay much attention to the instructions and took only one each day as a probiotic. I didn’t notice a lot of benefits, so I wasn’t conscientious about taking it. However a few months ago, I watched a video by Dr. Lee, where she explained the benefits of the various ingredients in Bio-X4, and how they work. Then I realized for the first time that I should be taking it several times a day, and particularly before meals, to get ALL of the benefits. Not only is my appetite under control, but my digestion is much improved; heartburn is all but gone. More importantly, I have become very regular and healthy.

Blown Away!

For the first time in my life, since I can remember, I am able to walk through a supermarket and not have any cravings for sugar or salt or junk food! It is so liberating! And I feel great! All I crave are healthy foods and snacks like nuts and carrots and hummus. I have a lot more energy, mental clarity, and my mood has been a lot more positive. I have noticed some weight loss; clothes fit better, but the rest of the changes are phenomenal. I know I am on my way!

I have more energy and feel more energetic throughout the day. It also suppresses my appetite and helps with cravings.

I feel great!

The weight is coming off, my cravings are gone, gas is reduced by 80% and I’m loving it! Another month like this and I will be ready for the beach!

I have been meaning to send you an email commenting on how well I’m doing. I have had diarrhea for almost 15 years now and I have gone to many many doctors. With no results from all these many doctors, I saw your ad on my phone as the poop doctor. And read your article on my phone so I thought well I’ll try it. I ordered three bottles and I have been taking one pill every morning since April 4 of this year. I have to tell you that it has regulated me. I am almost diarrhea free. I have a nice soft bowel movement first thing in the morning. And so far most of my days are diarrhea free. Thanks 🙏

Nucific bio-x4

I feel a bit better less hunger between meals, but haven’t lose any weight

I have been taking Bio-X4 for about 3 weeks. I have noticed better digestion and less cravings for food. I also have noticed I look slimmer in the belly area. I have ordered another 30 day supply as I am anxious to see how much more this will help me!

Nucific BIO - X4

I am pleased that I have given BIO-X4 a try. It has helped in my weight loss goals, as well as curbing my appetite. I don’t seem to have as many digestive issues as once before and will definitely be purchasing more once my initial 3 month supply runs low.


Apr 26 2024

I lost 13 pounds in a month


This product changed me for the better. Not just because of the weight loss. But I had wayyy less bloating and I knew my digestive system was working more efficiently because I was finally eliminating regularly. I also increased my physical activity, drank plenty of water and made more nutritious food choices while taking this supplement! It was a holistic approach and it all worked great!

Nucific Bio X-4

My wife and I have been taking one before each meal. The changes I have seen and felt are better digestion, less bloating and stomach discomfort, more energy, and it seems to have improved waste elimination.


Apr 21 2024


Excellent help with cravings and nice metabolic response. I have become a gut microbiome believer thanks to Dr Lee.


Apr 19 2024

Feeling great!!

After taking the BIO-X4 for only a few days, my appetite was better controlled and I had more energy than I had for a while. I doubted that the change was from this supplement so I stopped taking it for a few days. The result—I was back to feeling sluggish and hungry again. This definitely works! Thank you!


Apr 16 2024

Excellent results

I had a doctor prescribe a broad spectrum antibiotic. It devistated my microbiome. I’ve tried for several years to find a probiotic to help fix the problem, or at least improve my gut. Most over the counter products actually made my gut worse, resulting in massive bloating and flatulence. X4 is the best thing I have found to date, to help re-regulate my gut. My stools have returned to some semblance of normal, while flatulence and bloating have been reduced noticeably! The bacteria strains have helped far more than the other products I have tried!


Apr 15 2024

Nucleic bio-x4

It seems to be working for me, but I have to take to casually per meal. They are cutting down my bloating and I am still losing weight with the nucific bio-x4, I’m going to have to order some more soon! I love what the product is doing for me

I am finally progressing in my long weight-loss attempts (of a lifetime) and actually am seeing very good results since I started on this supplement. Thank you for this wonderful product.

It works!

Read the emails, saw the videos and thought, “why not”. The main reason for taking this was to see improvement with bowel movements and digestion overall. Finished my first bottle and I can say, I’m a happy customer! I must say the increase in energy was also a nice side effect. As for weight loss, there’s none yet but I haven’t tried. The main factor for taking this was gut health improvement and I think this does the job!

Bio x4

Since I started taking Bio x4 , after about two weeks I’ve started feeling better, not so bloated. It is helping me curb my appetite also. I’m taking it along with the vshred diet plan. I’ve now lost about 5 lbs. it feels good to be finally losing some weight.

They say that slow and steady wins the race and that best describes this supplement. I have not changed my eating habits at all but have lost about 4 pounds in the last couple of months. That does not sound like a lot to you. Well, it is if you have not changed your eating habits. Also, I do not have a lot of weight to lose but I sure do not want to gain any either. The best thing that I have noticed is I do not get hungry and start craving unhealthy snacks. That in itself would lead to losing weight especially if you are an emotional eater and/or you have a lot of weight to lose. It could do wonders to help you. I say try it and see what it can do for you.

happier guts

Although I have yet to lose weight, my digestive system is definitely happier. I’m sure if I continue to use it, weight loss will follow. just for how my system feels, I am looking forward to getting another bottle to keep things going.

My BIO-X4 Progress So Far


I just finished my first bottle of BIO-X4. When I began taking them, I first had to get my sequence of when and how many I take adjusted and aligned with my eating habits. I received an email from Amy Lee sharing best tips for taking BIO-X4 and that really helped me. Well, I had already begun noticing more energy, which was great. One Saturday afternoon I was changing the linens on my bed, and I stopped to consider how I might want to rearrange the room. I stood there with my hand on my waist and suddenly I noticed for the first time, I had an indentation where my waist was supposed to be. I got so excited!!! OMG I had recovered my waistline, there was a definite dent there where my hand could rest comfortably. Yesssssss. Since then I’ve only weighed myself once, and I have lost about 5 or 6 pounds. I am working on incorporating more activity into my day, as my daily job is at a desk for 8 hours. I know as I make these changes more weight will come off. Also, I find that I’m only eating when I’m hungry. A co-worker asked me what I was doing differently. I told her and sent her a picture of my BIO-X4 bottle that I keep in my desk at work. Thank you for this formula and all of your hard work putting it together. I’m excited to keep going for more results.
