Bio X4 Ingredients
Bio X4 is an excellent option to improve your digestive health and promote weight loss at the same time. Many weight loss and digestion support supplements only focus on one of these factors without realizing that your digestion and weight [5] are so profoundly interconnected.
By combining both of these factors into a single product, you can finally get to the root of your weight loss issues and improve your digestive and metabolic functioning. Bio-X4 contains only natural ingredients that support your body’s overall functioning and can continue to support your health even after you reach your weight loss goals.

The crucial component that makes Bio X4 an unforgettable supplement option is the 4 factors it addresses through its unique ingredient blends. All of these different ingredients work together synergistically to impact the most critical aspects of digestive health and weight loss.
Bio-X4 contains 4 unique blends: the Probiotic Blend, the Digestive Enzyme Blend, the Weight Management Blend, and the Unhealthy Craving Control Blend.
Probiotic Blend
The probiotics in Bio X4 come from two main blends: the lactobacillus blend (L. acidophilus, L. rhamnosus, and L. plantarum) and the bifidobacterium blend (B. lactis and B. animalis). This potent probiotic combination contains 4 billion CFU per capsule and can combat unhealthy gut bacteria and improve your digestive health [6].
Digestive Enzyme Blend
The digestive enzyme blend in Bio-X4 contains 43mg of three enzymes: amylase, lipase, and bromelain. This combination of digestive enzymes [7] promotes your body’s ability to break down food, absorb nutrients, and ease digestion. With this digestive enzyme blend, your body can better break down carbs, fats, and proteins to ensure that everything you eat is processed well.
Weight Management Blend
The weight management blend in Bio-X4 is 100mg of green tea extract. Green tea is well known as a potent antioxidant [8] that improves energy and supports weight loss. The antioxidant properties of green tea help your overall health while improving your body’s ability to burn calories and lower your appetite.
Unhealthy Craving Control Blend
The unhealthy craving control blends in Bio X4 is essentially 166mg of an herb called Caralluma fimbriata. This herb comes from an edible cactus originating in India. Research suggests that Caralluma fimbriata [9] can help you feel fuller after meals so that you don’t get as pulled into the desire to snack.
Health Benefits of Bio X4
The main health benefits of Bio X4 are its impact on digestive health and weight management. In addition to digestive health and weight loss support, Bio-X4 helps your body in the following ways:
- Regulates cholesterol levels
- Promotes regular bowel movements
- Increases metabolism
- Combats unhealthy gut bacteria
- Increases food breakdown and nutrient absorption
Potential Side Effects
Like many other supplements that improve your digestive health, it can also sometimes worsen symptoms depending on your unique situation. Some customers report experiencing mild digestive discomfort, particularly gas, bloating, and constipation. But these are common side effects of probiotics and digestive enzymes that may simply require lowering the dosage.
The green tea extract [10] may overly stimulate some people due to the caffeine content. But green tea has less caffeine than coffee, so the effects are likely minor, particularly if you are a regular coffee drinker.
How To Take Bio-X4
Bio-X4 comes in convenient capsules that should be taken with meals. The recommended dosage is 1-2 capsules with each meal with a maximum of 6 capsules per day.
What Food to Avoid While Using Bio-X4?
Due to the caffeine and probiotic content, you may want to reduce your daily coffee or caffeine consumption and limit other fermented foods with additional probiotic content.
In general, you can consume any other foods you want while taking Bio-X4 because the contents have little to no interactions with other ingredients. But of course, it is always advised to continue on a healthy diet to promote healthy digestion and weight loss. Supplements are not a miracle cure and should always be combined with regular exercise and a healthy diet[11].
Bio-X4 Review: What Do Real Users Say?
Although some users reported minimal weight loss and some worsened digestive issues, the vast majority of customers experienced exceptional results from Bio X4. See below for a few excerpts from real customers who used Bio-X4 and left glowing Bio-X4 reviews after their experience.
“The BIO-X4 by Nucific is AMAZING! HONESTLY, before taking this, I would raid my pantry after work…chips, cookies, anything & everything I could put in my mouth! So I started taking BIO-X4 B4 every meal and I have a bottle at work too… I kid you not, I don’t have the ridiculous hunger I had before taking this prebiotic! I don’t have the cravings I used to have, and no more BLOATING!”
Ali
“I purchased these products and used them for 6 months. I ate a clean diet after 1-2 months. Lost 30 lbs in 6 months. Might not sound like a lot, but it was; because of other medical issues, I’m not very active. Best product I’ve ever tried for gut issues. I’m reordering as my diet slacked a bit, then eating foods my gut cannot help without assistance. I already know my remedy. Totally recommend this product. I went to GI Dr. for some tests and had been taking the product for 3 months. Well, all tests came back really good, to the surprise of myself and Dr., the proof was in the product. Very happy.”
Cindy
“I have been using Bio-X4 for just over a month. While I haven’t lost any weight yet, I do feel more energy and what’s even more important is that my cravings for carbs and sweets have gone way down! I have read reviews to give it at least 90 days or more, so I’ll keep on using.”
