What is ProbioSlim?

Updated on: Oct 31, 2017

Containing a revolutionary probiotic LactoSpore, Probioslim is a supplement that promises to help you with healthy digestion, recharge the good bacteria, and promote weight loss.

According to the website, Probioslim states that by combining “groundbreaking” probiotics and prebiotics with “revolutionary” weight loss ingredients. In fact, the company specifically claims ProbioSlim is “one of the best ways to lose weight,” safely and naturally.

On top of this, ProbioSlim promises that each one of their ingredients has been researched and vetted by the company’s Harvard- and MIT- trained scientists. As a result, you may notice some benefits within days of starting ProbioSlim, with maximum benefits occurring in about three months’ time.

It seems like there’s always some new weight loss bandwagon to jump on, but is this probiotic the real deal? Can you expect it to help you lose weight? If so, how much? These are all important questions we’ll help you answer in this review.

First, Some Background About Probiotics and Prebiotics

To understand how products like ProbioSlim work, we need to quickly talk a little biology.

Your body is home to about as many bacteria cells as your own, most of which are housed in your digestive tract. There, they help aid in digestion by breaking down food and protecting the body from potentially harmful byproducts or other microorganisms.

The really neat thing is that, like fingerprints, each of us has a unique bacteria makeup in our gut, based on the foods we eat and our exposure to the environment in which we live.

Now, there are two important things to remember here. First, as you might imagine, not all bacteria are good for us. Second, everything we discussed above occurs under ideal circumstances.

Taking these ideas together, there are certain instances where too many non-beneficial bacteria can accumulate, potentially leading to digestion problems (gassiness, bloating, etc.), weight gain, lethargy, and even a decreased immune response.

To combat this situation once it occurs, you can take a supplement containing billions of beneficial bacteria cells, known as a probiotic. These help repopulate your gut with specific bacteria strains that can help reduce bloating and gassiness, relieve constipation, decrease certain allergic reactions, boost immune response, and more.

What Kinds of Results Can You Expect with ProbioSlim?

Although there isn’t a label on the ProbioSlim website, we’re told it contains LactoSpore probiotics, green tea leaf extract for weight loss, and fig, kiwi, and papaya extracts as prebiotics. Let’s break each of these down.

LactoSpore is a proprietary probiotic formulation consisting of the Bacillus coagulans bacteria strain, which is owned by the Sabinsa Corporation. The company claims it has been used in clinical trials for the “treatment of gastrointestinal disorders, vaginal infections, hypercholesterolemia, lactose intolerance, hepatic coma and precoma and as an adjuvant to antibiotic therapy.”

Notice anything? Weight loss isn’t among any of LactoSpore’s clinically proven benefits. In fact, there is very little clinical evidence showing that probiotics in general (not just ProbioSlim specifically) can help you lose weight. What about the other ingredients?

The fig, kiwi, and papaya extracts in ProbioSlim only act as a prebiotic, or a food source, for the billions (numbered in colony-forming units) of bacteria contained in each capsule. As such, these ingredients won’t help you lose weight.

Finally, we have green tea leaf extract. Here’s how the company markets it:

“An innovative green tea complex helps enhance thermogenesis and fat oxidation so you can burn more calories. Caffeine provides a boost of energy and helps control appetite as part of a reduced-calorie diet.”

Green tea is a long-studied drink that contains polyphenols (antioxidants) and epigallocatechin gallate (EGCG), which might help provide some heart-healthy benefits, much-needed hydration, and bodily support.

However, while there is some limited evidence showing these substances can boost metabolism, the increase is so slight that it likely won’t have any meaningful effect on your weight.

ProbioSlim Side Effects

While the green tea leaf extract in ProbioSlim probably won’t cause you to lose a meaningful amount of weight, the good news is that it probably won’t cause any side effects worse than mild digestive upset, either.

However, keep in mind that green tea has some natural caffeine content (often about as much as a cup of coffee), so this might affect you more strongly if you’re especially sensitive to stimulants.

As far as probiotics in general (not ProbioSlim specifically), the most common side effects reported are gas, bloating, and digestive upset—which is weird, because aren’t these the symptoms probiotics are supposed to address in the first place? In most cases, if you experience anything at all, these side effects will typically subside within a couple of days. If not, you’ll definitely want to speak with your doctor.

Is ProbioSlim Advanced More Effective for Weight Loss?

Recently, the company released ProbioSlim Advanced. In addition to the LactoSpore brand of probiotic we discussed above, the supplement also contains Meratrim, PreticX, and a Premium B Vitamin Matrix (B1, B2, B6, B9, and B12), as part of their LS9947 Super Lipolytic Megablend. Are these any more effective for weight loss?

Meratrim is a proprietary ingredient that combines garcinia mangostana and sphaeranthus indicus. Unfortunately, neither Meratrim nor the ingredients it contains have much (or any) clinical evidence showing them to be effective for weight loss. However, these constituents do appear to have some antioxidant, anti-inflammation, anti-cancer, and anti-diabetic effects.

We didn’t find a website for PreticX, although we did come across several press releases from early 2015. According to this release:

“PreticX is a GRAS certified and Non-GMO verified prebiotic that has been shown in clinical studies to significantly increase the proliferation of bifidobacterium in both low and high doses.”

While PreticX might help “feed” bifidobacterium (a strain of probiotic), keep in mind that there doesn’t appear to be any bifidobacterium in ProbioSlim, so it might not have any of these same benefits. And even if there was, as we discussed above, there isn’t enough clinical evidence to say that any strain of probiotic bacteria can help you lose weight.

Finally, unless you’re deficient, we didn’t encounter any clinical evidence that vitamins B1, B2, B6, B9, or B12 can help individuals lose weight.

ProbioSlim vs. Other Probiotic Supplements

You probably know that there are hundreds of different probiotic supplements available, both online and in-store. Compared to the competition, what sets ProbioSlim apart? Why is it worthy of your attention? According to the company:

“Unlike other probiotics, the ingredient LactoSpore® forms its own spores that protect the release of probiotics until it has safely passed through the harsh environment of the stomach and reached the colon. This prevents stomach acid from killing off the beneficial microorganisms and counteracting ProbioSlim’s effects.”

Is this necessarily unique, though? In short, yes and no. For example:

  • PerfectBiotics claims to use a unique fermentation process to help bacteria pass unharmed through your stomach.

  • Culturelle features a special species of bacteria that are especially resistant to stomach acid.

  • Probiotic Pearls features True Delivery Technology, a proprietary encapsulation process that decreases the chances of stomach acid destroying any bacteria before making their way to your gut.

We could keep going, but the point is that: 1) Many other supplements also feature LactoSpore, so ProbioSlim isn’t necessarily unique in this aspect. 2) Many other supplements also feature different technologies that allow their probiotics to sidestep stomach acid.

How Much Does ProbioSlim Cost?

One bottle (60 capsules) of ProbioSlim will cost you $69.99, plus $4.99 S&H.

You can also order a 14-day trial of ProbioSlim for $4.99 S&H. After 18 days (14 days for the trial, plus another 4 to allow for transit), you’ll be enrolled in their VIP program.

This means you’ll keep receiving a new bottle of the probiotic once per month and charged $74.98 each time (plus tax if applicable).

All orders come with a 30-day refund policy, less S&H charges. Note: According to the company’s Terms: “To receive your refund, your return must be received at our shipping facility within 30 days of purchase.” In other words, don’t wait until the 29th day to send it back!

In order to request a refund or to cancel your autoship enrollment, the company's customer service department can be reached at 877-452-7826.

Comparatively—although you’ll also find ProbioSlim available at dozens of local retailers like Walmart, along with popular websites like Amazon, the Vitamin Shoppe, and more—most other probiotics tend to fall in the $20-$30 range.

What Do Customers Think of ProbioSlim?

Here on HighYa, ProbioSlim has garnered nearly 56 reviews since our original writeup, giving the supplement a 2-star rating. Most compliments seem to reference better digestion, improved regularity, and just a generally “better” feeling.

On the other hand, most complaints appeared to reference failure to work and problems with the trial (usually that they were unaware they’d be enrolled in an autoship program). However, customer service seemed responsive and even replied directly to several complaints.

Elsewhere online, ProbioSlim had a 4-star average rating based on 45 reviews on GNC.com and a 3.5-star rating on Amazon, our of 823 customer reviews.

Is ProbioSlim a Good Probiotic and Weight Loss Supplement?

Based on all the available clinical evidence for the B. coagulans strain in general, and for the proprietary LactoSpore product specifically, it’s pretty clear that these probiotics (and many others) might be able to help provide a range of digestion-related benefits. Everyone’s different though, so just be sure to speak with your doctor beforehand.

Related to weight loss? According to the available clinical evidence, we think that if ProbioSlim did provide any boost to your metabolism, it would likely be slight.

Might it have a cumulative effect when combined with proper diet and regular exercise? Perhaps. But at twice the price of much of the competition, only you can decide if ProbioSlim provides enough value to make up for this difference.

    I started taking ProbioSlim the middle of May with the trial. In those 14 days I lost 11 pounds. I had no side effects. The product let me eat anything I wanted but I reached a point that I did not want anymore to eat. It really curbed my appetite. I have lost 45 pounds. I know that seems slow but that is how weight loss should be. I have also dropped 4 sizes in my clothes. Every so often I do get some nausea with vomiting about 3 hours after taking my medications (about every 3 to 4 weeks). People have noticed the loss. I have about 100 pounds more to loose. I love this product and its results. I was considering surgery but not anymore. There were about 3 weeks where I did not loose any weight but I put on a pair of jeans I had not been able to get over my hips. I slid into them easily. I am a semi-retired RN aged 67 with fibromyalgia, so exercising is very difficult for me.

    The Product Worked

    • New Orleans, LA,
    • Feb 10, 2016
    • Verified Reviewer

    Probiotics were not something I was aware of before starting to take ProbiSlim. I had no idea what they were or how they helped my body. All I knew was that I needed some help managing my weight.

    I did some research on a few different probiotic formulas that aim to help with digestion and weight management. I decided to go with ProbioSlim. The following week I ordered my trial of ProbioSlim and was happy with the product. I was feeling better and the results were starting to trickle in. I take one pill in the morning with breakfast and one in the afternoon with my lunch. I have lost a few pounds already, but more importantly I just feel better inside. I don't really know how to explain the feeling, other than to say I plan on continuing to take it. Definitely impressed with my results thus far.

    ProbioSlim

    I took Probioslim for 3 months. I changed my diet to more fruit less sweets. I have a hard time limiting sweets but I lost 15 lbs during those 3 months and have maintained to keep off 13 lbs. I will start back but I can not find the product in my local stores. I do not want to get involved in a mail order. I'll keep searching. Thank you

    Love it!

    I started taking ProbioSlim in May 2016 and with a balanced diet and exercise lost 50 pounds. In November 2016 I had some life stress happen and completely stopped. Fast forward to July 2017, I decided I needed to get back on my weight loss journey, but didn't go directly to ProbioSlim, and I tried other probiotics. None of those worked for me as well as ProbioSlim. It is not a magic diet pill and definitely needs to be taken as recommended and with a balanced diet and exercise.

    Bottom Line: Yes, I would recommend this to a friend

    Happy Tummy!

    Although weight loss was hoped for, I did not have that happen possibly due to medications and hormonal deficiencies. As an older person, I am delighted with the beneficial results for my digestion and elimination, which keeps my tummy from bloating and discomfort. Using fiber did not help, but the probiotics have made a huge difference. Hope this helps you, too!

    Customer service was fine

    I was wary of the auto shipping, but interested in the product, so I placed an order. After seven days, I called customer service to cancel, and was given another offer, which was the free bottle still in transit, the next month's shipment for free, an extension of the trial period to six weeks from that day, and a reduced monthly cost if I continued with ProbioSlim. The customer service agent said that they were having problems with Canadian shipments. I canceled not long after the second free bottle arrived, with no problem and no extra charges.

    I've had less gas and lost weight, but I've also been eating less. I do find that the green tea extract gives me more energy.
