Young, healthy woman for a BioFit Review article

Probiotic supplements have been making waves all over the world. In 2020, Statista reported that the probiotic supplement industry was making billions. Probiotic supplements marketed for gastrointestinal health were predicted to reach a $1.5 billion market value in 2023. 

One of these probiotic supplements is BioFit. The supplement is supposed to help people lose weight by supporting the gut microbiome. Additionally, it also helps with boosting the metabolism. That’s not the real kicker, though. 

BioFit claims that you can lose several pounds with just their supplement. No exercise, no calorie counting, and no portion control. Theoretically, you should be able to lose weight while stuffing your face with your favorite food. 

This review will cover how BioFit works, its ingredients, its pros and cons, customer response, and more.

What Is The BioFit Probiotic Supplement?

BioFit is a weight loss supplement from Nature’s Formula. These vegetarian capsules have almost seven probiotic strains that help you on your weight loss journey. They strengthen your gut microbiome and help you get more good bacteria. 

They also improve your digestion so you can eat whatever you want—no more skimping on your favorite foods. According to Nature’s Formula, BioFit helps you lose weight naturally. 

What Does BioFit Claim To Do?

Weight loss isn’t the only thing you’re signing up for. You also get other unbelievable benefits like a faster metabolism, accelerated fat loss, no more inflammation, detoxification, reduced oxidative stress, and lower stress levels.

BioFit can also help regulate your sleep cycle, giving you a decent amount of sleep. It also increases your energy levels and gives you an immune boost. In short, BioFit is a complete package that will help you with everything. It sounds like a miracle, so let’s look at the weight loss supplement’s ingredients.

BioFit’s Ingredients

BioFit has probiotic strains. Probiotic strains are bacterial strains that help you instead of making you sick. You can usually get them through yogurt and other fermented food sources. 

Bacterial concentration is measured through CFU (Colony Forming Units). BioFit has 5.75 billion CFUs per unit. That’s just one pill. BioFit’s company claims all these ingredients have been clinically studied.  

BioFit uses seven probiotic strains. These are:

  • Bacillus Subtilis

B. subtilis is one of the few probiotics from the Bacillus family that has been cleared for human use. Studies have shown that this strain can help against weight gain from a high-fat diet. They do so by decreasing the amount of fat accumulated under the skin and other body parts.

A 2018 paper reviewed the effects of B. subtilis supplementation in mice with a high-fat diet. The study showed that the bacterial strain protected the mice from fat-induced obesity and insulin resistance which can contribute to diabetes. 

It also protected them against non-alcoholic fatty liver disease. The bacterial strain also inhibited inflammation in the muscles and liver during the study. It regulated lipid oxidative genes to decrease adipose tissue (fat) accumulation under the skin and abdomen. 

These effects are encouraging, but the human models’ results weren’t as good. BioFit uses a particular strain of B. subtilis, i.e., DE111. Another 2018 study investigated the effects of this strain’s supplementation on the immune and hormonal profile of athletes. 

These people weren’t obese and maintained exercise routines during the study. Body composition, including fat percentage, was one of the studied markers. After 12 weeks of supplementation, the researchers didn’t see any beneficial changes in the fat percentage of the participants. 

B. subtilis is effective in decreasing body weight in animal models. However, it hasn’t shown those positive results in human subjects yet. More studies are needed on the subject. 

  • Lactobacillus Casei

The BioFit weight loss supplement also contains L. casei. The Lactobacillus strains are usually present in yogurt. Moreover, this strain is also present in your intestines. L. casei can survive in acidic and high-temperature situations. 

Studies have shown that this bacterial species can help with weight loss, prompting its addition to probiotic dietary supplements. In 2015, a study compared the effects of L. casei Shirota and Orlistat (anti-obesity medication) for weight loss in rats. 

The study involved thirty-two rats and spanned over fifteen weeks. After fifteen weeks, the rats showed improved body weight management. They also showed lowered levels of fat mass and alanine aminotransferase. 

Later in 2017, another study investigated the strain’s effects on obese children. The Shirota strain showed positive results here too. The children showed better lipid metabolism and weight loss. Thus, the Shirota strain of L. casei is effective for weight loss.

  • Lactobacillus Rhamnosus

L. rhamnosus resides in your intestines. It’s a common probiotic, and many producers add it to dairy products to increase probiotic content. It’s helpful in treating diarrhea and IBS, improving gut health, and preventing cavities and UTIs. 

It’s also rumored to help with weight loss. However, there are not that many studies to prove that. In 2014, a study observed the effects of the strain on obese men and women. The weight difference between the placebo and control groups wasn’t that significant. However, the supplement helped women lose weight more than men. 

Another experiment in 2017 showed that women who took the L. rhamnosus supplements didn’t have as many cravings as men. Thus, it can help control the diet, leading to weight reduction. 

  • Lactobacillus Acidophilus

Another bacterial species found in your intestines, L. acidophilus, is another probiotic. Supplement companies claim that this probiotic strain can help you lose weight. However, the studies have shown different results. 

A 2012 meta-analysis shows that L. acidophilus causes weight gain in human and animal subjects. However, it does increase Bifidobacterium in the intestine. The Bifidobacterium bacteria can help with losing weight and digestive health.

  • Lactobacillus Plantarum

L. plantarum is a common lactobacillus species. The food industry uses it to ferment different foods like yogurt. This species can reduce inflammation and insulin insensitivity, common causes of obesity. 

A 2021 study used a hundred participants to observe the effects of the strain on overweight individuals. The study maintained the anti-inflammatory effects of the strain. However, it didn’t show any significant changes in the abdominal fat percentage of the participants. 

A 2020 study with mice showed different results. This study showed that L. plantarum was decreasing lipid accumulation by affecting the genes involved in lipogenesis. It also lowered the overall weight and abdominal fat in the mice. 

Another 2017 review paper showed that these effects were dependent on the stains of L. plantarum used. Some strains help with weight loss, while others show no effect. However, some strains help with weight gain. Nature’s Formula hasn’t revealed which strain they use in the diet supplement.

  • Bifidobacterium Breve

The Bifidobacterium family also lives in your digestive system, especially the intestinal tract. A 2010 study studied B. breve’s effects in obese mice. The supplemented diet suppressed weight gain and decreased weight loss. They also activate genes that metabolize fats and increase insulin sensitivity levels. 

Another 2018 study investigated these effects in pre-obese adults. Eight pre-obese adults participated in this study which continued for twelve weeks. After 12 weeks, the body fat levels were significantly lower in the group that received B. breve B-3. 

  • Bifidobacterium Longum

The B. Longum species is also present in the gastrointestinal tract. It has also shown weight loss effects in animal models. In 2021, a study investigated the results of the B. longum species in obese mice and human adults.  

The primary goal was to see the effect on Body-Mass Index (BMI). The secondary objective was to study the impact on waist circumference and obesity-associated biomarkers. The mice showed it decreased weight and fat mass. 

On the other hand, the adults didn’t show a significant difference in BMI or abdominal circumference. Though, the blood glucose levels did decrease. That means that the strain can’t induce weight loss but can help lower some obesity-associated biomarkers. 

How Does BioFit Work?

The BioFit tablet has a protective casing to protect probiotic strains from stomach acid. The probiotic strains are slowly released and must make it to the intestinal tract to be effective. 

These probiotic strains enhance the digestive system, encouraging more efficient digestion of the food you eat. Theoretically, probiotics can help you lose weight by increasing your metabolism, producing a thermic effect, reducing cravings, and burning fats. 

Studies have shown probiotics to be effective in losing a few pounds. However, BioFit claims it can help you lose up to seventy pounds with little to no exercise or diet restriction. 

Nature’s Formula claims that BioFit can help you lose that much weight by regulating your eating schedule. It reduces cravings. Cravings make you eat processed food with fat and sugar content. Lack of cravings helps you stick to a regular meal schedule, letting you lose weight. 

Additionally, it can optimize your digestion. It encourages nutrient absorption and proper breakdown of the food. That makes you feel fuller and eat less. Furthermore, it helps the waste matter exit your body quickly. 

The efficient digestive process results in the proper breakdown of the food. That means you won’t feel as bloated. Being bloated can make you look fat. So, BioFit also helps you look slim. 

Alternatives to BioFit

Of course, there are other more reliable weight loss supplements out there. With so many on the market, it might be hard to find one that is authentic. You can look at our recommendations to see if something will help you. However, none of these products are capable of miracles. 

You can only lose weight if you follow a decent diet and exercise. You can have your favorite foods, but getting a pizza for dinner every day won’t make you lose fifty pounds. So, you have to be mindful of your lifestyle as well to achieve your desired results. Customers who have used these supplements and made some changes to their lifestyle testify to their effectiveness.

How Much Weight Can You Lose With BioFit?

According to Nature’s Formula, you can lose a whopping seventy pounds by taking BioFit. That’s a lot of pounds. Moreover, they also say you can lose all this weight without any sort of exercise. You don’t even have to count your calories or avoid any food. 

Apparently, all these claims are supported by proof. By proof, the company means customer testimonials in their video. The video shows women losing thirty, forty, and seventy pounds after eating their favorite foods and no exercise at all. If that’s true, BioFit is genuinely a miracle weight loss supplement. 

Frankly, we haven’t come across any probiotic that can do that. Probiotic supplements are just a tool in your weight loss journey. For healthy weight loss, you need portion control and exercise. These factors can help you burn fat and get in shape. 

A supplement should only be able to help you achieve these results a bit faster. If you’re already at your ideal weight, you can take probiotic supplements to maintain that weight. Even then, you’ll have to care for your diet and do some exercise. 


There are plenty of scammy websites and retailers out there. However, BioFit is only available on the official website. The website has three offers:

  • One bottle for $59
  • Three bottles for $147 with free shipping 
  • Six bottles for $234 with free shipping

These are all discounted prices. So, we don’t know how long they’ll last. The actual cost for a single bottle is $149. If you order now, you also get three free bonuses:

  • The Truth About Dieting – A book about how you can lose weight permanently. The original price is $39.
  • Favorite Desserts – A collection of healthy desserts that you can have to soothe cravings. These desserts won’t make you fat, and their original price is $69.
  • Private Members Area – This is a private space where you can access exclusive meal plans, start guides, and healthy recipes. Usually, you have to pay $99 for complete access. 

Money-Back Guarantee

The product also comes with a money-back guarantee that’s as unbelievable as the product itself. BioFit has a 100% satisfaction guarantee. According to the website, you can get a refund if your blood sugar levels aren’t to your liking after using the probiotic supplements. 

You have a six-month window to apply for a refund. You can return the product, no questions asked. A credit card refund shows up in five to seven days, while a debit card refund shows up in five to ten business days. 

Theoretically, you should be able to return the product if you don’t see any changes in six months. The product can be opened or unopened. However, we don’t know if the company follows through with this guarantee. You won’t get any return on the shipping costs.

About the Manufacturer

Chrissie Miller developed BioFit. Chrissie is a forty-three-year-old mom with three kids. After her pregnancies, she “blew up” to the point where her waist was forty-six inches. Chrissie tried numerous diets and exercise programs, and they worked. However, she couldn’t stick to them. 

Then she came up with BioFit, based on her own experiences. She isn’t a doctor or a nutritionist. She didn’t want to listen to a man in a white coat tell her what to do because they couldn’t look for something that would work for a real woman. 

Chrissie Miller thought about what had worked for her and came up with this miracle formula. The whole point was to find something that ordinary people could stick to. You can see the full 51-minute video here if you want to hear more.

Customer Response

According to the website, thousands have proven weight loss claims. The website itself only has three reviews. The picture at the top has more reviews with before and after images. You can also hear quotes like, “I lost three pounds this week, and I had milkshake and custard donuts for breakfast.”

We tried to find reviews outside the website and saw some very aggressive marketing gimmicks. The supplement’s Facebook page turned something up. There are two reviews though the business shows up as not rated. 

One user said she had been using the supplement for three months while dieting and hadn’t seen any results. Another said they had gained four pounds after using it for four days. The comments were even more revealing.

Apparently, a customer had applied for a refund. However, the company rejected the claim. BioFit team replied that due to COVID, they only refund damaged or defective products. If customers wanted to return the product within fourteen days, they could get a refund. However, all the repayments would be in the form of BioFit vouchers worth the product’s value. 

Aside from those claims, you need to know that people have different bodies and react differently to various products. So, always take the customer reviews with a grain of salt. Before you commit, however, ensure BioFit is right for you and you are not allergic to any ingredient.

BioFit – To Buy Or Not To Buy?

Given the 160-day refund policy, we might have asked you to try the product yourself. But there’s no guarantee that the company will honor it. Additionally, the refund policy is worded in a way that makes you think you can return the product after using some of it. 

In truth, they only promise a refund for unopened bottles. So, if you don’t see any effects and have only bought one bottle, they’re not technically required to give you a refund.

Probiotics are effective in helping you lose a little weight. However, none of the ingredients in this formula have been clinically proven, and the FDA doesn’t regulate the supplement. 

The product may work if you maintain an exercise routine and a decent diet with portion control. However, if you think taking a pill daily is all you’ll have to do, you’ll be disappointed.  

Additionally, the developer has been contradicting themselves. They say they wanted to create something that will help you lose weight without any of the usual weight loss techniques. However, they also give you dessert recipes that help you stay slim and access a meal plan. 

FAQs Related To Biofit Probiotic Supplement

Is BioFit safe to use?

Yes, BioFit is safe to use. All the ingredients used are naturally-existing components. Moreover, you can also get your doctor’s opinion before committing to the supplement.

How soon will I start losing weight when using BioFit?

Because all our bodies are different, you might react to BioFit differently from another user. However, you should see changes within a month. Remember that you have to make changes to your diet and lifestyle as well for the best results.

Is BioFit effective?

Some customers who have used BioFit have testified to its effectiveness. However, if you are not getting the results you want with BioFit, there are other dietary supplements you could try like PhenQ, Leanbean or Instant Knockout.

Final Verdict: Best Alternative Of BioFit Supplements!

That was all we had to say about fat loss supplements. Probiotics are fine and all, but they aren’t some holy grail to help you shed tens of pounds in no time. They help speed up the process, but you must maintain a healthy diet and exercise.

The intensity of the exercise depends on how much weight you’re looking to lose. If you want to shed a lot of weight, we recommend something like PhenQ and PrimeShed. These supplements help you lose weight quickly. 

However, they’re honest about it. They don’t claim to be miracle workers. If you want to lose weight, you have to put in the work. Simply taking a pill won’t do anything. You can try BioFit, but we have no reason to recommend it. Not when other much more efficient weight loss supplements are on the market.
