What Is DuoTrim?
Duo Trim is an independently verified, unique slimming supplement that combines healthy probiotics with clinically studied weight loss ingredients to nourish your gut and produce a more balanced approach to dropping excess pounds. Its said to work in spite of the fact that DuoTrim does not contain addicting stimulants like caffeine, amphetamines, hordenine, higenamine or unhealthy ingredients like garcinia cambogia, which can damage your liver.
How Does DuoTrim Work?
The Ingredients in the supplements are said to function in tandim to help you better metabolise carbs and burn fat. The ingredients are also said to help you produce more of a special type of gram-positive bacteria called Christensenella minuta, which until recently was unknown. Preclinical research suggests that a deficiency of the C. minuta microbe plays a role in metabolic diseases like diabetes as well as being overweight. Skinny people tend to have
a lot of C.minuta, and the concentration of this probiotic increases when people lose weight. Overweight and obese people tend to have less of this bacteria. Interestingly, this microbe tends to be absent in the guts of people with various health problems such as irritable bowel syndrome, ulcerative colitis, and Crohn's disease. The fact that it is missing in these people leads some to think this probiotic may offer protection from these conditions. Other research studies suggest C. minuta bacteria also appear to support healthy aging too.
Christensenella minuta Probiotic Summary of Effects
C. minuta is found in the digestive tract of humans. While it was newly discovered, research so far appears to link this microbe to an assortment of benefits, such as:
- Better LDL cholesterol levels (bad cholesterol)
- Lower triglycerides
- Healthier blood pressure
- Lower levels of the liver enzyme called ALT (alanine transferase)
- Maintaining oral health
- Being thin/skinny/Lean
While these potential benefits could be game-changing, remember many of these effects need to be validated in humans.
What Are The Main DuoTrim Benefits
Based on the ingredients in the supplement combination and what the manufacturer tells us, we can infer that DuoTrim has these advantages:
- Aids in fiber intake
- Supports the suppression of appetite
- Maintains healthy digestion
- Modulates metabolic rate
- Supports healthy microbiome diversity
How Do You Take DuoTrim? Use Directions
To get the maximum benefits, the company suggests these straightforward recommendations:
- In the morning, take two capsules from the yellow DuoTrim Burn bottle
- In the evening, take 1 capsule from the blue Duo Trim Active bottle
Take the supplements with food along with at least 8 oz of water
What Are The Ingredients in DuoTrim
Since this is a supplement combination, it may seem logical to ask which is the superior supplement- DuoTrim Burn vs. DuoTrim Active. But this is incorrect thinking because the company intends them to be taken together, albeit at different times of the day. With The Active DuoTrim, you take one capsule per day, while it's two capsules a day for Duo Trim Burn. Here are the ingredients in each supplement side-by-side:
| Duo Trim Burn (proprietary blend 800 mg) | Duo Trim Active (Probiotic Blend 5.75 CFU) |
| Acacia Gum | Lactobacillus acidophilusus |
| Agave Inulin | Lactobacillus rhamnosus |
| Flaxseed | Bifidobacterium longum |
| Galacto-oligosaccharides | Lactobacillus plantarum |
| Guar Gum | Bifidobacterium breve |
| Bacillus subtillis | |
| Lactobacillus casei |
What Proof Does DuoTrim Have?
If you look at the company's website, you will see that they list ten different clinical trials as proof that the supplement works as advertised. While it's good that they provide this information for those who are doing their research, none of those investigations specifically refers to the DuoTrim supplement. Let's look at the ingredients in DuoTrim and what they might mean for weight loss.
DuoTrim Burn Ingredients
Acaia Gum
Acacia gum, also known as gum Arabic, is a soluble dietary fiber that is derived from the sap of the acacia tree. In theory, acacia gum may help support healthy weight loss in several ways:
- Reducing appetite: Acacia gum can help reduce hunger and increase feelings of fullness, which can lead to a decrease in calorie intake.
- Reducing calorie absorption: Like other dietary fibers, acacia gum is not easily digested, and as a result, it passes through the digestive system without adding unwanted calories. This means that consuming acacia gum can help reduce the number of calories absorbed by the body. In one investigation, when researchers gave one ounce of Acaia gum to women each day, the fiber supplement reduced both the percent body fat and body mass index after just six weeks.
- Promoting gut health: Acacia gum is a prebiotic fiber. This means that it feeds the good bacteria in the gut. These bacteria can help regulate digestion and metabolism, which can contribute to weight loss. Those good bacteria also produce substances such as butyrate, a short-chain fatty acid, that our bodies employ to stay healthy.
- Lowering glycemic index: Acacia gum has been shown to have a low glycemic index, which means it does not cause a spike in blood sugar levels. This might help prevent overeating, fatigue and contribute to weight loss.
Agave Inulin
Agave inulin is a type of soluble dietary fiber derived from the agave plant. It has been suggested that consuming agave inulin may aid in weight loss in several ways:
- Reducing appetite: Dietary fiber such as agave inulin can help reduce hunger and increase feelings of fullness, which can lead to a decrease in calorie intake.
- Reducing calorie absorption: Inulin is not easily digested by the body, and as a result, it passes through the digestive system without adding calories. This means that consuming agave inulin can help reduce the number of calories you eat per day.
- Promoting gut health: Inulin is a prebiotic fiber, which means that it feeds the good bacteria in the gut. These bacteria can help regulate digestion and promote microbiome diversity, which may contribute to weight loss.
In one clinical study, agave inulin probiotics lead to a significant increase in healthy bifidobacteria and short-chain fatty acid production in healthy people after just three weeks of use.
Overall, incorporating agave inulin into your diet may help with weight loss by reducing appetite, reducing calorie absorption, and promoting gut health. However, it's important to note that agave inulin alone is not a magic solution for weight loss and should be consumed as part of a balanced diet and healthy lifestyle.
Flaxseed
Flaxseed is a nutrient-rich plant-based food that is an excellent source of dietary fiber, protein, and healthy fats. Flaxseeds have a variety of health benefits:
- Flaxseed is high in dietary fiber, which can help reduce hunger and increase feelings of fullness. This can lead to a decrease in calorie intake and aid in weight loss.
- Like other dietary fibers, flaxseed is not easily digested by the body. This means that consuming flaxseed can help reduce the number of calories absorbed by the body.
- Providing prebiotic fiber. Flaxseed fiber can ramp up the number of good bacteria in the gut. These healthy bacteria can help regulate digestion and metabolism, possibly fostering weight loss.
- By promoting weight loss, flaxseeds help reduce Inflammation in the body. Flaxseed contains omega-3 fatty acids such as alpha-linolenic acid (ALA), which have been shown to have anti-inflammatory properties and may help reduce inflammation in the body.
- Several studies have reported that flaxseeds can lower blood pressure. In one study, people eating just 1 oz of flaxseeds saw a significant 15-point reduction in systolic blood pressure after six months.
- Regulating blood sugar levels: Flaxseed contains lignans, which are plant compounds that have been shown to help regulate blood sugar levels. This can help prevent overeating and contribute to weight loss.
Galacto Oligosaccharides
Galacto-oligosaccharides (GOS) are a type of fiber found in foods, including beans, lentils, and chickpeas. It has been suggested that consuming GOS may aid in weight loss in several ways:
- GOS can help reduce hunger and increase feelings of fullness, which can lead to a decrease in calorie intake at the end of the day.
- GOS is a prebiotic fiber, so it promotes good bacteria good in the gut.
- Regulating blood sugar levels: GOS have been shown to help modulate blood sugar levels. Some studies suggest that GOS can improve dysbiosis and increase the production of healthy bifidobacteria in people with type II diabetes. Bifidobacteria are associated with improvement in glucose intolerance, one of the hallmarks of type II diabetes.
- Some research suggests GOS can increase fat oxidation – fat burning- but this has not yet been demonstrated in humans.
Guar Gum
Guar gum is a soluble fiber derived from the seeds of the guar plant (Cyamopsis tetragonoloba). In foods, it is commonly used as a thickening and stabilizing agent.
When consumed, guar gum forms a gel-like substance in the digestive tract that can slow down the digestion and absorption of carbohydrates, fats, and proteins. This is similar to how glucomannan (konjac fiber) works. As guar gum slows digestion, it increases feelings of fullness and reduces overall calorie intake. This can curb appetite and promote healthy weight loss.
Additionally, guar gum has been shown to have a positive impact on irritable bowel syndrome (IBS), blood sugar control, and cholesterol levels.
Duo Trim Active Ingredients
Lactobacillus acidophilus
Found in yogurt, lactobacillus acidophilus is one of the best-known healthy gut probiotics. This microbe is associated with a wide range of benefits, including:
- Improved digestive health: Lactobacillus acidophilus can help to maintain a healthy balance of beneficial bacteria in the gut, which can improve digestion and reduce symptoms of digestive disorders like irritable bowel syndrome (IBS).
- Healthy immune function: Lactobacillus acidophilus can help the immune system work better, which may improve resistance to infection, particularly in the respiratory tract.
- Lactobacillus acidophilus has been shown to aid people suffering from diarrhea caused by antibiotics.
- Lactobacillus acidophilus appears to reduce inflammation in the gut, which can benefit individuals with inflammatory bowel disease (IBD).
- Improved vaginal health: Lactobacillus acidophilus can help to maintain a healthy balance of bacteria in the vagina, reducing the risk of bacterial vaginosis and yeast infections.
- Some research finds Lactobacillus acidophilus can help lower levels of total and LDL cholesterol in the blood however, not all studies show this. More research is warranted.
- Improved oral health: Lactobacillus acidophilus can help to reduce the growth of harmful bacteria in the mouth, reducing the risk of cavities and gum disease.
- Some research suggests lactobacillus acidophilus may help people suffering from depression. While this is intriguing, more research on the gut health-depression link needs more research.
Lactobacillus rhamnosus
Lactobacillus rhamnosus is a gram-positive, lactic acid-producing probiotic found in fermented foods like kimchi and sauerkaut, as well as in the digestive system of healthy people. This probiotic is associated with several health effects, including:
- Helping to maintain a healthy balance of beneficial bacteria in the gut, improving digestion, and reducing symptoms of digestive disorders like diarrhea and irritable bowel syndrome (IBS).
- Lactobacillus rhamnosus can help modulate the immune system, keeping it robust.
- Reduced inflammation: This friendly bacteria can reduce inflammation in the gut, which means it may benefit those with inflammatory bowel disease (IBD).
- Improved vaginal health: Lactobacillus rhamnosus can help to maintain a healthy balance of bacteria in the vagina.
- Some studies suggest that Lactobacillus rhamnosus may reduce the risk of developing allergies in children.
- In one study, women who took lactobacillus rhamnosus supplements for twelve weeks lost almost 4 pounds (1.8 kg). Interestingly, weight loss did not occur in men.
Animal research suggests Lactobacillus rhamnosus supplements improve insulin sensitivity and reduce body weight gain in obese mice. However, this needs to be verified in humans.
Bifidobacterum longum
Like other probiotics found in DuoTrim, Bifidobacterium longum is bacteria found in the gut of healthy people. It produces both lactic acid and acetic acid. This bacteria also helps humans break down carbohydrates and sugars and may benefit those with digestion issues such as irritable bowel syndrome.
Some research suggests that Bifidobacterium longum may have potential benefits for cognitive function, including memory. One study revealed that healthy adults who took a Bifidobacterium supplement for 12 weeks had improved cognitive performance, including memory, compared to a control group who did not take the supplement.
Lactobacillus plantarum
This beneficial bacteria naturally inhabit the human gut and is commonly found in fermented foods such as kimchi and sauerkraut. L. plantarum has been studied for its potential health benefits, including:
- Reducing some types of eczema.
- Some research hints that Lactobacillus plantarum may maintain a healthy immune system. At least one study appeared to show resistance to the common cold.
- Some research suggests that Lactobacillus plantarum may modestly reduce cholesterol levels.
Bifidobacterium breve
This healthy gut bacteria, while receiving less clinical research than others in the DuoTrim formula, have been linked to supporting healthy immune function and modulation of inflammation. When overweight men and women were given bifidobacteria breve supplements or placebo pills for 12 weeks, those taking the probiotic saw significant reductions in total body fat and percent body fat.
Bacillus subtillis
Bacillus subtillis is an interesting microbiome with quite a bit of human studies. Various clinical trials have noted that Bacillus subtillis appears to:
- Support healthy gut bacteria and microbiome diversity.
- Produce natural antibiotics that work against harmful microbes.
- Improve blood vessel function.
- Reduce cholesterol.
- Improve constipation and diarrhea symptoms.
- Reduce inflammation.
- Reduce body fat in women.

Lactobacillus casei
This healthy microbiome has been associated with the following benefits:
- Positive modulation of the immune system.
- Possibly helping people battle allergies.
- Supporting oral health and inhibiting the formation of dental plaques that cause cavities.

On the bottle label, we see that the supplement is distributed by CKD Media Ltd care of EyeFive Inc. Who are they? It's difficult to pindown CKD Media because so many businesses appear to share this name ranging from a British retail company to a Nigeria sports network. EyeFive Inc. is an online shipping broker.

Does DuoTim Have any Side Effects or Adverse Reactions? Is it Safe?
When this review was created, no legitimate side effects were discovered for this supplement combination. While this is good, remember any popular product which is taken by millions of people is bound to reveal some individuals are unhappy. The company cautions customers to not to exceed the recommended dosage or use the supplement if they are under the age of 18. Store the DuoTrim in a cool/dry place whose temperature does not exceed 86 degrees F (30 degrees C).

- You are pregnant or breastfeeding.
- You are going to have surgery, including dental surgery.
- Are you taking any medications or have any health problems?

Duo Trim vs. BioFit Probiotics: What's Better?
BioFit is another heavy hitter when it comes to probiotic weight loss supplements. While no clinical trials could be located that compared the effectiveness of DuoTrim to BioFit, here is how they compare to each other. With DuoTrim, you take two capsules per day. Directions for BioFit call for using just one capsule per day. However, when you compare DuoTrim Active Probiotics to BioFit Probiotics, something interesting is revealed. They are the same!
DuoTrim Active vs. BioFit Probiotics Comparison
| DuoTrim Active (1 capsuel 5.75 CFU) | BioFit (1 capsule 5.75 CUF) |
| Lactobacillus acidophilus | Lactobacillus acidophilus |
| Lactobacullus rhamosus | Lactobacullus rhamosus |
| Bifidobacterium longum | Bifidobacterium longum |
| Lactobacillus plantarum | Lactobacillus plantarum |
| Bifidobacterium breve | Bifidobacterium breve |
| Bacillus subtilis | Bacillus subtilis |
| Lactobacillus casei | Lactobacillus casei |
What does this mean? One thing this tells us is that both companies feel this choice of bacteria is important. One downside to Biofit is that it is just a probiotic supplement. Since it does not include the synergistic fiber and prebiotic ingredients that DuoTrim has, BioFit might be inferior. This might give the edge to DuoTrim supplements.
Is DuoTrim FDA Approved?
It is wise to choose only supplements that are independently verified for potency and quality. This will ensure that a supplement contains what is listed on the label. In the US, the Food and Drug Administration (FDA) does not approve dietary supplements before they are sold to the public. However, they do have regulations in place to ensure supplement manufacturing is safe. That said, the makers of DuoTrim have gone the extra step of getting 3rd party verification. All DuoTrim supplements are certified by NSF (National Sanitation Foundation). This well-respected company thoroughly tests dietary supplement ingredients and manufacturing processes to ensure they meet strict standards and are free from harmful substances.
Can You Purchase DuoTrim on Amazon?

- Does not show you the ingredients.
- Contains possibly harmful ingredients like garcinia Cambogia, which is linked to liver failure.
- Contains raspberry ketones, a fake ingredient that does not work.
- Has stimulants like caffeine.
- Has Exogenous ketones such as BHB.
To be clear, fake versions of DuoTrim are out there. Avoid them, as they won't work the same as the safer, legit product reviewed here.
