BioSlim’s not your grandmother’s diet product. We dug deep into the ingredients, side effects, clinical research and customer service. Additionally, we dissected hundreds of comments and reviews. We then condensed and refined to give you the info you need.

BioSlim Readers: Click here to find out why we're giving away samples of our product, Burn HD.

What is BioSlim?

Firstly, BioSlim is a weight-loss system. The program consists of Ultra Slim Tone Formula, Ultra Vita/Min Plus, BioSlim Accelerator, Doctor’s Reference, BioSLim VideoGuide, Active Planner
Cook Book and PocketBox. What are the ingredients in BioSlim? Some essential ingredients include:

  • BioSlim Pyruvate Complex
  • Green Tea
  • Quercetin
  • Chromium Polynicotinate
  • Siberian Ginseng
  • B-Vitamins

Depending on the product, the recommended serving is once per day. This is supposed to help the dieter lose more weight. One of the benefits is that it’s easy to use.

The product line, launched as a diet program in 1989 by Medicus International, doesn’t appear to use synthetic ingredients in select formulas, a good start. We do like that the company has been in operation for more than 25 years and some comments are positive, but read on…

Looking at the Customer Service Quality of BioSlim

The first concern we had with BioSlim was the quality of customer service. “Consumers willing to invest in a supplement want support in the event of a question or concern,” said our Research Editor. “What they expect is a team willing to address comments in a timely manner. If not, dieters will simply pass on the products.”

“The customer help on the other end was rude, mimicked me and used sarcasm the whole way through the conversation,” reported a consumer.

“I bought BioSlim and BioCleanse. They debited my account and never turned up. I rang in January and they said they were out of stock and would come soon. They still haven’t turned up and now I cannot get hold of them,” commented a dieter.

When we are researching, we typically find some positive comments alongside the negatives. There doesn’t seem to be any support for the customer service department.

BioSlim Customer Testimonials

BioSlim Weight-Loss Claims

According to the testimonials on the BioSlim website, dieters are seeing some pretty amazing weight-loss results, maybe too good. It’s safe to lose up to two pounds a week, but some report losing upwards of 33 a month. “I lost almost the full 200 pounds in just my first 6 months on BioSlim,” one consumer claims.

“Kevin lost 153 pounds in his first 7 months on BioSlim!,” says the BioSlim website.

There are clearly some outrageous weight-loss claims, but some dieters saw more realistic outcomes. One said, “For me it has been good, because I don’t have any of those problems that I had before.”

Another shares, “I’ve been on it for a good few months and had some weight loss. You have to exercise discipline and follow the diet.”

Our research shows that any part of a diet system thought of as a concern, such as outlandish weight-loss claims, could hinder long-term success. If BioSlim says the dieter will lose a ton, but then they don’t, why should they stick around?

The Science – “Any Real Proof to Support BioSlim?”

The ingredients in BioSlim are simple enough – green tea and vitamins. We like the first because there is some science there, but you can pick it up at a convenience store or vitamin shop for about $5. At DietSpotlight, we feel customers deserve clinical proof and this product has none.

The Bottom Line – Does BioSlim Work?

So, with all the facts under our belt, what do we say about this one? The length of time in the industry and the fact that some comments are positive, but we have doubts about it because the weight-loss claims aren’t supported by published clinical research. Plus, we’re concerned about the quality of customer service and the long list of complaints about company sales practices.

If you’d like to shed the pounds, we recommend going with a product that is both cost effective and packed with ingredients backed by published clinical research.

Among the best supplements we’ve seen this year is one called Burn HD. The formula contains a four-ingredient proprietary blend, which has been shown in published scientific studies to help increase fat loss and ignite metabolism. There’s no one talking about adverse side effects and reviews around the web show people are seeing excellent results.

The makers of Burn HD are confident in the supplement, so they’re offering a 2-Week Sample, a good choice.

Licorice Root

Licorice root is derived from the Glycyrrhiza glabra, which is naturally grown in southern Europe and Asia. It is often used as a flavoring agent.

What Is It Supposed To Do?

Licorice has been used in traditional Chinese medicine for many years. It is thought to have an antiviral, anti-inflammatory, hepatoprotective, laxative, and blood pressure effects on the body.

Clinical Research

According to an article written by the University of Maryland Medical Center, “More studies are needed to say if licorice really helps reduce fat. In addition, taking licorice long term has a number of health risk.”

Glucomannan

Glucomannan is a sugar that is made from the konjac root. It can be found in powder, capsules, and tablets.

What Is It Supposed To Do?

Glucomannan is used to treat constipation, low cholesterol, type 2 diabetes, blood sugar, and excess weight-loss.

Clinical Research

In a study published in the Journal of Obesity, researchers noted that glucomannan may not have the effects many companies claim it has. In the conclusion, it said, “In summary, glucomannan supplements (3.99 g daily) were well tolerated but did not promote weight loss in overweight and moderately obese individuals consuming self-selected diets and maintaining usual physical activity patterns. Other outcomes such as body composition, hunger/fullness, and lipid and glucose parameters also were not significantly altered.”

Atractylodes

Atractylodes is a plant that used often in traditional Chinese medicine.

What Is It Supposed To Do?

Atracylodes are used to treat indigestion, bloating, diarrhea, and more. The plant works by chemicals working to improve the function of digestive tract.

Clinical Research

A study published in Evidence-Based Complementary and Alternative Medicine, researchers concluded, “This study indicates that ATR might improve appetite, therefore might partially explain why large-head atractylodes rhizome can improve appetite in the light of TCM theory. What’s more, ATR could down-regulate the serum IL-1 level, and up-regulate serum TNF level. This might partly explains why ATR has the ability to improve appetite, and reverse weight loss.”

Siberian Ginseng

Siberian ginseng is a plant often considered an adaptogen. The root is often used for various medicines.

What Is It Supposed To Do?

Siberian ginseng contains chemicals that effects the brain, immune system, and hormones. It seems to affect the heart, blood vessels, athletic performance, insomnia, and more.

Clinical Research

In a study published in the Journal of the International Society of Sports Nutrition, researchers stated, “The vast majority of well-controlled studies have reported no significant effect of either Panax ginseng, eleutherococcus senticosus Maxim L, Ciwujia, or a standardized ginseng extract on cardiovascular, metabolic, or psychologic responses to either submaximal or maximal exercise performance, or on maximal or supramaximal performance capacity.”

What You Should Know about BioSlim

Bioslim is a weight loss system that began over 15 years ago. This program involves kits that are suited for adults and also separate ones for children trying to lose weight. The adult kit is called "Bioslim 2000 Ultra Complete," while the children's kit is called "Bioslim Youth System Complete." More specifically, the adult kit contains a "six-week supply of formulas." This involves the Ultra SlimTone Formula (60 tablets), the Bioslim Accelerator (36 tablets), Ultra Vita/Min Plus (60 tablets), a Bioslim Cookbook, Dr.'s Complete VideoGuide, the Quick Start Guide, Dr.'s Health Reference Guidebook, an Activity PocketBox and access to the Doctor's hotline. This whole kit sells for $89.95. There are no free trial samples offered.

Unlike some weight reduction supplements and diet pills, Bioslim endeavors to offer a "permanent solution" to weight loss. The three supplements that come with the Bioslim 2000 Ultra Complete kit contain some active ingredients. In the Ultra SlimTone Formula there is Green Tea Extract (assists the metabolism), Bioslim Pyruvate Complex (lowers cholesterol and helps reduce body weight), Chromium Polynicotinate (burns away fat and sugar) and Coenzyme 10 (helps burn fat); in the Ultra Accelerator supplement there is Green Tea, Cotinus, Quercetin, Siberian Ginseng (normalizes blood sugar levels), Calcium (strengthens bones) and Pantothenic Acid; and in the Ultra Vita/Min Plus supplement there is Green Tea, Chromium Polynicotinate, Vitamins A, D and E, Bromelain (metabolizes fat) and a Super-Enhanced B-Complex (helps the immune system). There is a 6-week money-back guarantee offered with Bioslim products.

Product Features

Bioslim is basically a collection of weight loss systems that are tailored for either women, men or children. This program consists of dietary supplements that are taken daily, a cookbook, some workout videos, a health reference book and access to the "Doctor's" hotline 24/7. Some of the key ingredients found in Bioslim supplements are Green Tea Extract (assists the metabolism), Chromium Polynicotinate (burns away fat and sugar) and Siberian Ginseng (normalizes blood sugar levels). The Bioslim 2000 Ultra Complete kit for adults sells for $89.95. There doesn't appear to be any real clinical evidence presented on the website.

Advantages BioSlim

  • There is a 6-week money-back guarantee offered with the Bioslim weight loss system.

Disadvantages of BioSlim

  • There doesn't appear to be any real clinical data provided on the product to support the overall effectiveness of Bioslim.
  • Some ingredients found in Bioslim supplements may not be suitable for some individuals.
  • A Bioslim kit may prove to be a tad pricey for some individuals, since it sells for $89.95.
  • This weight reduction system may be a bit too involved for some dieters who prefer a simple capsule that's taken daily.

Conclusion

Although Bioslim offers and interesting take on weight loss with three different supplements, a cookbook, some workout videos, a health reference book and access to the "Doctor's" hotline, it may not be ideal for all dieters. On the bright side, Bioslim kits are offered with a 6-week guarantee.

  •  Easily loose my weight
    Virginia LeBlue (Verified User)

    I used the original Bio Slim a long time ago, and immediately was able to shrink my appetite and lose 35 lbs. within a period of 3 months. I was able to keep the weight off for over 10 years. I had some extra and shared it with 2 other people, but neither of them had any success in losing weight. I’m seriously thinking about ordering it again. I need to lose about 35 lbs, and hope it works as well as it did before. I’m a lot older now, and crippled up, so I hope it will help me to get back to a healthy weight again. I know I would feel a lot better and have a lot less pain if I could lose the weight.
