People are talking about Isagenix, so we thought it a good idea to take a closer look into the product ingredients, side effects, customer service and clinical support. We read user comments from hundreds of dieters all over the web. We took this information, summarized and compacted to give you the bottom line.
What Is Isagenix?
To start, Isagenix is a supplement company offering weight-loss solutions. Products from the company include shakes, formulas to flush toxins from the body and energy boosters. Some are taken in the morning and others at night. One good thing is that you can take the meal-replacements with you to drink on the go.
The products, introduced to the market around 2002, appear to contain all-natural ingredients, which is always good. Isagenix is available by phone and from marketing associates. We like the good BBB rating and the company has been in business for more than 13 years, but read on…
The price for Isagenix products was high for some customers; others felt it was "equal" to comparable supplements.
Price – “Over the Top?”
The first concern is the prices associated with Isagenix products. “You can’t put a price tag on weight-loss, but there’s a problem when a company charges two or three times that of others,” says our Research Editor. “You can purchase the 30-day weight-loss program for around $350.”
“I should have listened to my smarter side before dishing out close to $400 for this product, but I’m only human and fell for the empty promises that their website offered,” according to one customer.
Another dieter said, “This is an very small jar for the very high price.”
We do have to keep in mind that a high cost to some is not expensive to another. As one buyer says, “Great price/Great product.”
We also found one user who compared one product to similar ones on the market. She claimed, “My favorite way to start the day and price is approximately equal to other protein shakes.”
Scroll below for one of the best products we’ve seen over the last year.
Poor Customer Reviews – “Something to Think About”
We read through hundreds of customer reviews on forums and websites. A large percentage of the comments were negative. Bad flavor and no results were two of the more common complaints. “All of this stuff tastes nasty. Like a big glass of grape Robitussin,” offers one dieter.
“I didn’t like it. It made me feel nasty. It wasn’t what I expected. Didn’t work for me,” claims a customer.
Still another user says, “I tried this for a week and saw no difference in my weight, health or energy.”
Just because there are negative reviews doesn’t mean there are no positive comments. “It just becomes a way of life…a healthy way of life,” says one user.
Another offers, “I have had success with weight loss and feeling better with these products.”
In our research, we’ve found a strong connection between the small things, like poor customer experience or high price, and a negative effect on long-term success. If Isagenix fails the dieter in any way, that’s a red flag.
The Science – “Any Real Evidence?”
Isagenix offers videos and marketing materials, but no real “science.” There is some evidence meal-replacement shakes can help a dieter lose more. But Isagenix does not present clinical research supporting any claims. At DietSpotlight we look for published data to back up a company’s weight-loss claims. If that does not exist, to us that’s a warning.

The Bottom Line – Does Isagenix Work?
Has the time come to sprint out for these products? The Isagenix company has longevity on its side and a supportive customer service department, but we have hesitations about recommending supplements without clinical support. We’re also concerned about the high price and negative customer reviews.
If the time has come to shed those extra pounds, we suggest a supplement with good customer results and a blend of ingredients supported with scientific research.
Among the best products we’ve seen in 2016 is one called Leptigen. It’s made of a proprietary blend of four ingredients showing a positive effect on fat loss and metabolism. There’s no talk among customers of harmful side effects. To make matters better, results are great, based on reviews.
The company responsible for Leptigen is confident enough to present customers with a Special Trial Offer – that’s a good sign.

What You Should Know
Isagenix is marketed as a company that wants to impact world health, according to the Isagenix website. The company has a line of products for cleansing, nutrition, and skin care. One of the products in the cleansing line, Cleanse for Life, is advertised as a tool for weight loss along with energy and good health. (Take a look at their wikipedia page
if you'd like). Other companies that have similar product lines are Yoli Better Body System
. with The bottles of Cleanse for Life are sold in a two pack, and each 32 ounce bottle is good for two cleansing days. This product appears to be recommended as a part of a complete system designed to cleanse your body over a 30 day stretch. It is also sold as part of the accelerated nine day program, which promises an average weight loss of seven pounds during that time frame. They also have meal replacement options, including shakes and soups. A similar meal replacement product is Prolessa Duo
which is an appetite suppressant.
The entire product line is available from the official Isagenix website, and also through a network of independent affiliate retailers similar to the classic Avon business model. We are pleased to see that the company provides complete ingredient lists for all of its products, but we are not so inclined to buy into the idea of a complete system with numerous products as the best weight loss method. It's nice to know Isagenix has a favorable BBB rating
. We believe that many dieters can find success through a low calorie diet, daily exercise and a single, effective weight loss supplement. Incorporating an exercise routines like PiYo
might help in the weight-loss process.
The ingredients in the berry flavored Cleanse for Life include a proprietary blend that contains aloe Vera leaf, IsaLyte trace minerals, Pau d'Arco inner bark, suma root, eleutherococcus senticosus root extract, burdock root, fennel seed, peppermint leaf, licorice root, choline bitartrate, inositol, betain HCL and I-methionine. We go over the Isagenix Ingredients
in greater detail here. Another similar weight loss product that contains aloe vera is Calorad
. By the way, it's interesting to view science produced by Isagenix themselves
We do not see anything on this list that stands out as an effective weight loss supplement. While many of the ingredients may be quite healthy in other ways, we prefer to see an appetite suppressant like Slim Trim U
or fat burners like Man Scorch
on the list for maximum weight loss benefits. Well known weight loss substances like chromium, green tea, guarana and hoodia are noticeably absent from this list.
Some of the Isagenix products appear to be quite pricey, although a double order of the Cleanse for Life sells for a reasonable $43 at the time of this review. We could not find any information about a free trial offer or money back guarantee.

- The idea of cleansing the body from the inside out does offer a number of health benefits.
- The company provides complete ingredient lists for its products.
- We could not find a money back guarantee.
- The product we looked at doesn't contain any proven weight loss ingredients.
- The product is sold as part of a complete package that includes many products and is quite expensive.
We like the idea of an effective cleansing product as a method of jump starting a diet. However, cleansing programs are rarely the best choice for long term weight loss. Another product that states that it cleanses the body is Diurex Water Pills
. This particular product doesn't pack much in the way of proven weight loss ingredients to instill much confidence from us in its ability to help dieters shed excess weight. We encourage dieters to look for more effective formulas from other companies for best results.

Isagenix User Tips:

Isagenix Side Effects:
When you think of natural solutions and weight-loss supplements you need to understand the two aren’t always synonymous with no side effects. There is always a possibility for adverse reactions with any formula, although Isagenix side effects are pretty uncommon, with each individual person comes a different set of tolerances.
Stomach aches or pains are typically swelling or irritation in the stomach or abdomen region. They can range from dull to severe and be caused by a number of factors.
What causes stomach aches?
Causes can be something as simple as eating the wrong food, or a food item that doesn’t agree with your stomach. It can be caused by stress or anxiety, or an outlying condition such as gall stones or pelvic inflammatory disease, though rare. 
Vomiting is the forced expulsion of the contents of your stomach through the mouth or nose. Typically preceding vomiting you will feel nauseous, sweaty, and/or experience abnormal amounts of saliva.
What causes vomiting?
Vomiting can be caused by gastrointestinal infections or disorders, ulcers, or irritable bowel syndrome (IBS). Motion sickness, stress and poor eating habits can also contribute to vomiting, as well as alcohol consumption or overeating.
A migraine is a common headache which can last from a few minutes up to days at a time and can often go along with flashes of light, nausea, tingling in the arms and legs, blind spots, vomiting, and increased sensitivity to light and sound. 
What causes migraines?
Migraines can be caused by a pre-existing condition or may be genetic in origin. Wine (and aged cheese) can cause a migraine due to the compound tyramine. You may experience a migraine with aura, which are bursts of neuronal activity proceeded by a span of inactivity.
Constipation can be classified as having hardened stool, fewer bowel movements, abdominal pain, or even vomiting. It’s the inability to pass your stool on a regular basis, often going days at a time without relief.
What causes constipation?
When the colon absorbs too much water, it contracts and doesn’t allow stool to pass normally. When this occurs, the stool is slowed down and dries out due to lack of moisture. If it loses too much water, it will become hard to pass and may obstruct the passageway. Dairy products, lack of fiber, and irritable bowel syndrome (IBS) are common causes of constipation.
Isagenix side effects are few and far between, but there have been reports of vomiting, constipation, and migraines, among some others. In order to save yourself from issues, you should always seek the advice of a doctor before taking any kind of weight-loss supplement. Specifically, if you are under the age of 18, pregnant or nursing, taking medications, or have a pre-existing medical condition.
Isagenix is a weight-loss company that offers both meal replacements and supplements. There is no shortage of product reviews and, though most mention nothing about side effects, we did find a few here and there.
“My first day of cleanse I ended up vomiting and dry heaving about 13 times. It was horrible. It made me so sick.” Regina
“I am constantly nauseated. I am weak. I have sharp pains in my stomach all the time.” Diana
“On my first cleanse day I felt even worse. Stomach aches, head aches, and sooo hungry. On day 2 of the cleanse I started getting very sick (diarrhea and horrible stomach cramps.)” Justin
“Ended up vomiting before I got to my last dose of the day, plus I felt like a zombie all day. On the second week I was constipated.” Tonia
“I kid you not, cramping up and down my digestive system and vomit convulsions except there was nothing to vomit up.” Kat
“It made me so sick and my guess is the high milk content. I didn’t even lose a lot of weight…after two weeks I stopped losing and got really bloated and sickly.” Tamara
“I’m only on my second day of the Isagenix 30 day challenge and I started feeling nauseous and I threw up. I still don’t feel too well.” Sarah
“I started Isagenix a couple of years ago. Had a VIOLENT reaction. Throat started burning, mouth burning, one of the worst migraines I had ever had.” Donna
“I started the 30 Day Cleanse a little over a week ago, and I MISERABLE! For the first 5 days, I felt hungry, I had headaches and waves of nausea.” Jess
“The product was awful, she tried it and vomited and it made her shaky and sick.” Ranae
“The supreme shot you take in the AM and the cleanse you do once or twice a week can make you sick, sick sick. Vomiting is an absolute side effect. I thought I was going to need medical attention it got so bad.” Regina
Isagenix offers a meal replacement shake (IsaLean) that supplies 240 calories, 24g of protein, 24g of carbohydrates (11g of sugar), 6g of fat and 8g of fiber. The milk-based shake is packed with a large percentage of many vitamins and minerals, but there's nothing unique in the formula.

We looked into the Isagenix ingredients to give you the details you need. Below are three of the most used.
Whey Protein Concentrate
Whey protein concentrate is derived from the watery portion of milk that is left behind when making cheese. It has many uses. It is often used for athletic performance or supplemental intake for those who are lactose intolerant.
What Is It Supposed To Do?
Whey protein concentrate is a source of protein that may help improve the nutritional content of your diet. It is possible that it can be used for eczema, allergies, psoriasis, and weight gain in those with HIV/AIDS.
In a study published in the Current Opinion in Clinical Nutrition and Metabolic Care, “…whey protein may affect glucose metabolism and muscle protein synthesis.”  However, they do suggest in the conclusion that more studies need to be performed in order to gain a full perspective on the substance.
Rhodiola Root Extract
Rhodiola is a plant. Its roots are used for various medicinal purposes. It is often used for energy, stamina, mental strength, and other physical ailments.
What Is It Supposed To Do?
When certain compounds are extracted from the root, Rhodiola is thought to, according to WebMD, “…help protect cells from damage, regulate heartbeat, and have the potential for improving learning and memory.”
In an assessment performed in Rhodiola published in the European Medicines Agency, “The published clinical trials exhibit considerable deficiencies in their quality. Therefore ‘well-established use’ cannot be accepted.”  However, the assessment did acknowledge the extract’s capability to help reduce stress.
Ionic Alfalfa Leaf Extract
Alfalfa is a plant in which its leaves, sprouts, and seeds are used for medicines. It is said that it may help with various ailments, including kidney, bladder, and prostate conditions.
What Is It Supposed To Do?
Alfalfa is supposed to help lower cholesterol, specifically by stopping or slowing the amount absorbed in the gut.
The University of Michigan’s Health System did some research on Alfalfa and found it may be used for menopause, high cholesterol, and poor digestion. However, there is no word of weight-loss in the information they provided.
