Dr Amy Lee’s Three Harmful Foods

Dr Lee made a video discussing three harmful types of “healthy food” that the FDA has still not banned. These are:


Bio X4 Ingredients

Bio X4 relies on four-ingredient blends to potentially support better digestion, control food cravings, increase energy and promote weight loss. The formulas include a:

  • Probiotic blend
  • Digestive enzyme blend
  • Weight management blend
  • Craving control blend

Bio X4 Ingredients

Probiotic blend (Lactobacillus Blend):

By taking 3 capsules per day, you cumulatively ingest 39 billion CFUs.

  • L. Acidophilus
  • L. Acidophilus
  • L. Rhamnosus
  • L. Plantarum
  • Bifidobacterium Blend:
  • B. Lactis
  • B. Animalis

Digestive Enzyme Blend:

  • Amylase (from Aspergilus Oryzae)
  • Bromelain
  • Lipase (from Rhizopus Oryzae)

Weight Management Blend:

Craving Control Blend:

L. Acidophilus is a common type of probiotic bacteria that may help prevent diarrhea, rebalance bacteria, fight allergies, control cholesterol and aid in digestion. [1]

The only ingredient in the Bio X4 Weight Management Blend is green tea extract.

Green tea is rich in catechins, which are a class of antioxidant-containing polyphenols. There’s research that shows green tea as an effective weight management ingredient.

A 12-week study found that people drinking green tea with 583 mg of catechins experienced a decrease in Body Mass Index (BMI) and overall body weight, as well as a reduction in abdominal fat. Additionally, this green tea-supplementing group experienced a decrease in unhealthy LDL cholesterol levels. [2]

Supplementing with green tea extract before exercising may boost calorie-burning and metabolism. A test group drinking green tea before workouts showed a 17% higher rate of fat-burning verses the group who did not.

Additionally, the green tea group [noticed] a 13% decrease in insulin sensitivity, a biological function that plays an important part in metabolic activity and fat-burning. [3]

Craving Control Blend

Caralluma fimbriata extract, a wild cactus plant that grows in India, contains chemical compounds that supposedly help control appetite.

A study examined the relationship between caralluma fimbriata supplementation, safety, and weight control. The group using caralluma did show a slight decrease in BMI.

T he participants in the study seemed to tolerate caralluma fimbriata extract well and it seemed to be safe. [4]

There is clinical evidence supporting many of Bio X4’s claims regarding the efficacy of its ingredients for weight control and overall wellness effects.

Does it Work?

Does Bio X4 Work?

Bio X4 is formulated to provide gastrointestinal tract support by supplying beneficial gut bacteria.

This, in turn, may help optimize health and promote weight loss.

Probiotics, such as Bio X4, may help restore “good” bacteria in your body and balance bacteria levels. We use probiotics to treat irritable bowel syndrome and allergic responses, as well as to boost the immune system.[5]

Does Bio X4 Work
Bio X4 ingredients such as green tea may increase energy and metabolism. Ingredients like caralluma fimbriata may suppress appetite. Through increased metabolism, boosted energy levels and curbing appetite, Bio X4 may help users feel better and lose weight.

It will most likely offer some level of digestion support through reducing some types of inflammation.


Bio X4 Results

As with most nutritional supplements, the longer you maintain usage on a daily basis, the greater the results you may see. The manufacturer recommends maintaining a steady daily regimen and, if you happen to miss a day, do not try to make up for the dose; simply take the recommended dose as per usual.

As for seeing peak results, the manufacturer states that you should be able to evaluate its max performance for you in 60 days effectively. Of course, instructions specify that you have to take the capsules regularly (on a daily basis) for them to work at their maximum capability.

The company claims that, as long as you keep working out and avoid eating sweets, you should be able to see results within a couple of months of taking the product.

Side Effects

Nucific — Bio X4’s parent company — says there are no side effects that they know of and that it is safe for most adult consumption.

While this may be true in general, it is important to note that anyone considering this supplement should read the nutrition label carefully to make sure none of the ingredients will trigger an allergic reaction (for those with certain food allergies). Better yet, it is always wise to consult with a nutritional or medical professional before beginning to use it.

In addition to triggering allergies and interacting with certain medications, nutritional supplements can sometimes produce mild side effects, such as:

  • Upset stomach

Always read the product label carefully and stick to the recommended dosage.

Where to Buy

Where Can I Buy Bio X4?

Because this weight-loss supplement is fairly new to the market, it is not available in stores at this time. Anyone interested should purchase it directly from the manufacturer to ensure authenticity and freshness.

Otherwise, there are a few reputable supplement vendors online from whom to purchase:

Amazon.com [6]

eBay [7]

Always do your research when considering a vendor. Again, read all company policies closely as well as any reviews associated with the company.


Bio X4 Directions

Per product instructions, users are to take one Bio X4 capsule with each meal. This includes breakfast, lunch and dinner, for a total of three capsules daily. By supplementing with each meal, the pills are designed to support digestive processes with fewer tummy troubles and potentially even greater nutrient absorption.

Daily supplementation, according to claims, may lead to greatly enhanced digestive health as well as faster weight loss.

Bio X4 Weight Loss

Caralluma fimbriata is one of the ingredients connecting Bio X4 to weight loss. Research shows users reduced body fat and decreased appetite. [8]

Green Tea, Bio X4 and Weight Loss

A myriad of cultures for its health benefits has used green tea for many years. Supplementing with it may help increase metabolism, decrease body fat, and help you lose weight. It also contains caffeine, thought to accelerate metabolism and energy levels.

A meta-analysis conducted on green tea’s effects on BMI and weight maintenance found that the catechins present in green tea significantly decreased body weight as well as maintained this reduced weight afterward.

How Does Green Tea Extract Help With Weight Loss

What Users Are Saying

“I tried this primarily for the probiotic impact. As I’ve gotten older, I’ve started to have minor digestive issues and increased bloating. It took a good couple of weeks for the effects to kick in but once it did, I felt a great deal better. I broke down and bought Bio-x4 strictly for the Probiotic benefits.”

“It helps with digestion.”

  • Megan

    If I was to start taking Bio X4 does that then mean that I would have to take it for the rest of my life to maintain a steady and healthy weight ? Or do I stop after I’ve reached my desired weight and take it every now and then instead of everyday ?

  • Angela

      • Bonnie Johnson


        Hi Moriba and Kaye, I am also Type 2 Diabetic and have Hbp as well. I have just started taking Bio X4 in the last 3 days. The biggest thing that I notice is that I don’t have any cravings and I am satisfied with less food as well as making better choices in the foods I am eating. Also I have stopped putting sweetener or sugar in my coffee and and shocked that I am not missing it. Kay, have you missed taking Bio X4 before a meal? If so what did you do? Thanks for sharing your posts.

  • I forgot to take it before my meal.
    Bonnie Johnson

    I forgot to take it before my meal. Should I take it while I am eating or just skip it?

    • Victoria (Editor)

      Hi Bonnie! The product label currently states that “whenever you are about to eat, simply take one capsule of Bio-X4 beforehand. Then, enjoy your meal!”. So, it might be best to just re-start fresh tomorrow since you forgot to take the product today.
