A few commenters expressed concerns about the product. One commenter said the Isagenix company representative couldn't answer questions about origin of ingredients and quality control. There have been no controlled studies. Where is the evidence? How do we know it is safe? Long-term results remain to be seen. How many can maintain this restrictive lifestyle for years? Why isn't Isagenix being regulated by the FDA? “I am a little concerned about the way some people discuss this product in almost cult-like fashion. It makes me wonder if there are mind-control drugs in this stuff.”

I’ve been enjoying this discourse, its nice if we can stick to logic, but I feel that various people are getting emotional on this issue. Just curious where you have the idea that ALL vegetable oils are inflammatory? At what point? Due to what? There are practically centuries recorded use of olive oil…what part makes it unhealthy?? Is not moderation the key? What makes soybean oil rancid and bad?

Well said and researched. I completely 100% agree with you. Too many ingredients are unhealthy and for a company to be touting how healthy and beneficial the products are… well you need to walk the walk. Here in Australia the products include several NUMBERS ( chemicals) and thickeners. As my partner put it when he tried a shake – “it tastes fake!”


Quite a few commenters reported that they had tried it and it either didn’t work or caused side effects such as 5 days of violent diarrhea. One reported gaining a lot of weight while taking it; many reported losing weight just as well without it. Several reported credit card disputes with the company and failure to get their money refunded. One reported that his parents are using it and it seems to be slowly killing them: they have decreased energy, declining health, mood swings, and poorer control of diabetes.
To be sure of bioavailability and potency, Isagenix provides ingredients either present in natural form or derived from natural food sources. We do not use any artificial or synthetic ingredients. In addition, Isagenix provides vitamins that are consistently tested for stability, purity, safety and efficacy. Each vitamin is evaluated using United States Pharmacopoeia standards or higher. They are sourced only from highly reputable suppliers with an excellent track record of meeting and exceeding cGMP guidelines.
I’ve lost a total of 20 pounds on Isagenix. This is partially due to Isagenix and partially due to working out and tracking my food log and paying close attention to what I’m eating. At first I refused to do the cleanse days because I don’t like NOT eating, but, the cleanse days have helped me drop those pesky last few pounds. I do agree that you can’t stay on Isagenix forever and you need to also learn how to eat whole, healthy, unprocessed foods. The meal replacement shakes are just so EASY for me, which is why I do it. I figure its better to fix a quick shake than going through the drive-through when I’m short on time. I think a lot of people realize or are skeptical if the products are legit, but, if you want to lose weight it makes it easier, which is all I care about right now! The sales aspect of the company IS annoying, and what I choose to take and ingest into my body is my choice, and I wouldn’t want to push this on others and promote it as “healthy” if I wasn’t 100% sure- I’m not a doctor or a nutritional expert.
You have an interesting perspective on my previous post about what the scientific community is saying about Isagenix. I can see how you might arrive at the opinion that all the experts are involved with Isagenix and therefore must be lying simply in order to promote the company and its products, thus putting their credentials and reputations in jeopardy if they are wrong.
3. And for the love of veggies, don’t go on a starvation diet! Diets that are 1,000 calories (and less) simply backfire. They are not sustainable, don’t provide enough nutrients or protein to keep your lean muscle tissue and they are so restrictive that it’s impossible to keep them up for long. When you return to normal eating, you’ve lost muscle—and lowered your metabolism—and weight gain is inevitable! Ahh!
7. Finally, You know your goal well, (IE, to become a bodybuilder, just to lose weight, general health). You aren’t going to become an IFBB bodybuilding pro from using Isagenix. It doesn’t have what you need to sustain that lifestyle. Want your pro card? This isn’t for you. Want help with a pesky 10 pounds, this might be for you. Want to lose 100 lbs? Isagenix can help. Yes.. help (refer to #4). Want help with changing eating habits, this could work for you.. if you educate yourself in the process. All this is going to do, is help you wipe the slate clean to begin new healthier habits. I can help you, but you have to first, be willing to help yourself, including learning.
Part of why many of us choose to involve ourselves with Isagenix is because of who we were. I don’t think schools should have vending machines. I don’t think companies such as McDonalds and Coca-Cola should be allowed to sponsor sporting events. I admire companies that don’t cut corners in the name of bottom line profits but most of all, I think people deserve to have facts when making decisions…especially regarding their health.
Several years ago, scientists discovered a brain detoxification process called the glymphatic system that occurs when you sleep. According to Andy R. Eugene and Jolanta Masiak, insufficient sleep impairs your glymphatic system, causing toxin build up. Without quality sleep in the right amounts on a consistent basis, your body cannot effectively detoxify.
Once again, when you are in a position where people look to you for advice, you have to present ALL the information. I feel that you have an opinion about Shake-based supplements in general and have made an assumption that this one is no different. In your charge to prove your assumption right, the perception is that you select to share only the information that supports your position and ignore or suppress that which contradicts it.
Ditch the packaged, processed foods today (even the “healthy” versions). This will ensure you are taking out excess sodium, artificial ingredients and sugar from your diet. Also, ditch the salt shaker and instead use only herbs and spices to flavor your food. You’ll find this can help make a big difference in how you look and feel. Even after one day!
I really dont care that your not FOR isa. Or that you prefer one product over another. Its sad you think that just eating organic is preventing you from taking in toxins. Evidence shows that even eating organic you are eating 1/2 a liter of pesticides every year! What about the stuff you drink or bath in……skin is the biggest organ we have. Its impossible to get away from them.

Here’s where some of the discrepancy lies… these people (and I was one) are spoon fed that the proteins come from grass fed cows and the whey protein is undenaturated, what they are failing to see is that your review questions the low heat non fat dry milk. Both of which can be true, the company may in fact use grass fed cows that produce the whey protein BUT it also adds low heat non fat dry milk 🙂
It depends on which 'program' you choose. The nine-day cleansing program, with products to "support healthy energy and help satisfy hunger", retails for $260, while a 30-day cleanse is $490. There's also a variety of products and product combinations on sale that retail from $29 for a single product to $783.00 for the 'Presidents Pak', which "combines best-selling products with proven marketing tools".

I take issue with anything listed as “natural flavors.” Because chances are, it’s not all that natural. Hell, even monosodium glutamate (MSG) can be masquerading as a natural flavor. The labelling is loosely regulated. In Food Rules: A Doctor’s Guide To Healthy Eating, Dr. Shanahan discusses a study in which 95% of ingredients listed as “natural flavor” contained MSG.
– Dr. John Anderson – Dr. Anderson made extensive plant tissue studies in organic soil. He discovered ionic minerals. In 1980, he translated his knowledge to the nutritional field. He has worked as a private-label supplement manufacturer and formulator for more than 600 companies, including GNC, Nature’s Sunshine, MetRx; creating more than 2,300 nutritional and weight loss products. His products are internationally recognized.
Organic agave nectar is relatively mild, is not chemically processed, and is free from harmful additives. This is the kind that Isagenix uses. Agave has beneficial properties which support digestive health. Agave contains naturally occurring inulin, a form of fructan found in a number of vegetables including onions, green beans, asparagus, and artichokes. The fructans in agave have been demonstrated to support the growth of beneficial microbial flora in the digestive tract. M.G. López and J.E. Urías-Silvas, “Prebiotic Effect Of Fructans From Agave, Dasylirion And Nopal,” ISHS International Symposium on Human Health Effects of Fruits and Vegetables (Québec City, Canada) 2007 (http://www.actahort.org/books/744/744_45.htm).
One does not need to be in the medical profession to be a researcher. Anyone can research products, or look up toxins that are on labels (for those of you who are unaware of this wonderful invention called books). If your unfamiliar with them, one can also opt for the lazy man research and look up products on the internet (also a wonderful invention). Looking up ingredients and conducting research isn’t rocket science. Dani, don’t waste your breathe on these individuals trying to discredit you. Spend your time, sharing your recipes and ideas–time much better spent.
So you had a few cookies! Ok, maybe you made your way through a tray. Fogetaboutit. No, really. Quit worrying and you’ll feel lighter—instantly! A study in the journal Appetite found dieters who associated chocolate cake with feeling guilty were less successful at losing weight compared to those who associated the indulgence with celebration. Researchers say food guilt can lead people to feel “out of control” and give up on weight loss goals. Another study in the journal PLOS One found a guilty conscience can literally weigh you down; participants reported a heavier self-perceived weight when they felt they’d done something wrong. Let go of the guilt, and remember those holiday cookies for what they were: a delicious tradition!
Thank you for posting this. I lost weight on the Isagenix system, however, I gained a fatty liver in return!!! (and no, I am not an alcoholic, which is usually why people get a fatty liver). I’m post pregnancy and not easily losing my baby weight so I contemplated returning to Isagenix for that quick fix…THANK YOU for reminding me that it’s just a bad idea all across the board!
My brother is pushing this ISACRAP stuff and I am extremely concerned. I warned him about the mlm- pyramid scam and was attacked by all of his “cult” so called friends. I have tried looking for negative feedback and finally found some using bing rather than google as a search engine. Found website where folks had some major medical issues. Hope this helps anyone trying to research before trying. Bottom line..eat healthy and exercise
You speak specifically about Calcium D Pantothenate. This is also referred to as vitamin B-5 or pantothenic acid, is an essential nutrient your body uses to generate energy by breaking down carbohydrates and fats. Adults should consume at least 5 mg of calcium D-pantothenate each day to maintain a healthy body, according to the University of Maryland Medical Center. If you have trouble getting enough of this B-5 vitamin from your diet, your doctor may recommend treatment with a calcium D-pantothenate supplement.
I too was encouraged to try that Isagenix product. 1 of my siblings is heavily into the scheme. She suggested it to me, and I tried it for almost 5 days until I started experiencing negative side affects. A week later she asked me if I wanted go with her to an Isagenix event where I’d become an associate., but after I naive agreed she informed me at the last minute that she needed to submit my social security number to the reps in charge so they could make an isagenix account for me, and for their tax purposes too. She had everything planned for the trip. But I felt pressured/trapped about giving out my ss number. I also did research about the product and I was shocked when I found it was a scam. It makes no sense why suddenly the company wants my ss number and insists I buy another of their products just to be a seller. So I politely informed my sibling that I refused to just throw out my personal info when I knew the company wasn’t Real!
I used the shakes twice a day for 6 days and developed headaches almost immediately. I didn’t relate them to the product until I talked to others who also had recently started and had headaches. the headaches were irritating, but not bad enough to treat with acetaminophen and ibuprofen. I then happened to take my blood pressure which was through the roof. That made me very concerned. The headaches went away and my blood pressure was down to normal when I went for my annual physical today.
Today the marketplace is cluttered with detox diets that promise to help you lose weight, boost your energy levels and more. However, many popular detox diets, especially those that involve extreme low-calorie fasting, can rob the body of important nutrients and place the body in starvation mode, which actually slows your metabolism. Other downsides of many detox diets include: dehydration, fatigue, dizziness, nausea and even colon damage.
It’s refreshing reading articles that are truthful and honest. From one Holistic Health Coach to another, thank you for spreading the word and educating people. I am trying to do the same thing and I always have people asking me me questions but when I give them the answer that they don’t want to hear, I get the rolling eyes and attitude and that includes family members. I don’t tell people what they want to hear, I give the facts and if they disagree, so be it. I really enjoyed your article. Keep spreading the word!
I also stated: They repeat the tired old myth that our food isn’t as nutritious as in the “good old days.” They put digestive enzymes in their products to help you assimilate them, not realizing that orally ingested digestive enzymes are themselves digested in the stomach before they can do anything. They say that their electrolytes “ignite the body’s electrical system” – I have no idea what this means, and it certainly is not scientific terminology. – Again none of them could comment.
Scott – Your inability to use the internets it not my fault or my problem. You’re one of those conspiracy theorists. There is no link between vaccinations and autism, yet you will ignore the science and claim there is. I am not going to spend time debunking your non-science. It’s a waste of my time, because you are not going to believe science anyway.
An Isagenix-funded study published in Nutrition & Metabolism in 2012 found that over an eight-week period, people who used Isagenix meal-replacement shakes as part of an intermittent fasting and calorie-restriction diet lost 2.2 pounds more than those who followed a similar diet using regular food. However, according to a 2012 article published on the Science-Based Medicine website, this study wasn't well-designed, and Isagenix paid to get it published in the journal. The author of the website article, Dr. Harriet Hall, also noted that there were inconsistencies in the numbers listed in the results, potentially making the conclusions unreliable.
You’ve obviously never tried it. You can spout off all the random information you want, but Isagenix makes me FEEL better than anything I’ve ever eaten. Something unhealthy could never make me feel this good. I’ve eaten whole, unprocessed, healthy foods my whole life, but my health completely turned around when I started adding Isagenix into the mix. Haters gonna hate, but you will NEVER, EVER convince me that Isagenix is unhealthy. It is the best thing I have ever done for myself. Cheers!

A vegetarian/vegan/raw diet is one of the most nutrient deficient diets on earth, not “the healthiest.” It’s not surprising that your blood work improved after introducing Isagenix. Going from an extremely nutrient deficient diet to Isagenix does not mean Isagenix is healthy, it means that it is a step above your previous diet. Is it ideal though? No.
This is where I realised that this review is actually not biased. Were you being ironic? Although you have put a lot of work into sourcing articles and quotes on the internet to validate your review, I cannot help but notice the tone of the article is negative and there are no positive points – pros for all the cons. That is where the credibility of the review falls down. Surely something in the ingredients is actually good? Your stance on pretty much everything is pretty much all-or-nothing thinking (see ‘splitting’ in psychology terminology).
Shame on them for “bashing” you. I hope you don’t feel that I’m one of them. I want you to know that I fully respect your efforts and that you truly believe in what you do. However, I also have a real soft spot for people who try their best but don’t have the knowledge to make an informed decision. I personally know people who have been taken advantage of and feel a personal responsibility to help.
Hi Dani, I absolutely love your article. You are extremely knowledgeable. I hate everything to do with GMOs and Monsanto. I avoid processed and non organic foods and only buy local organic foods. I am a health and fitness coach and I try to steer my clients towards organic products. Recently I have been asked about this product and I knew very little on it. The only thing I knew was they claimed to be “Non GMO and Organic” I now know they are not. Isn’t it a shame that we have to worry about what is in our food? I am so glad I stumbled upon your article!! Best wishes!!
Actually, they are. I definitely see your point and agree with you, but would expand it to say we are designed for natural foods like fruits and vegetables and animal products. Every culture in history has thrived on animal products, so much so that there has never, even been a culture that has only eaten fruits and veggies. Whey has been used for thousands of years, just not in protein powder form. That’s why I recommend this specific whey, it’s grass-fed and has undergone minimal processing.

Dani, I’m so sorry to have hijacked your thread, but these processed food nazi’s REALLY irritate me. They have NO clue what constitutes “real food” and NO idea what all the processing, pasteurization, low-heat, high-heat, super-pasteurized, artificially “enriched”, high-fructose enhanced, packaged crap REALLY costs us. Well, take a look around, take a look in the mirror . . . because WHAT you see IS what you get! /sigh sorry, I’m better now LOL.

However for people who are more passionate about fitness and nutrition, for athletes, and for those who already maintain a balanced diet with the input of a nutritionist, Isagenix is likely a step backwards – and this is where there always seems to be a conflict. Isagenix salespeople (that I have spoken to) will not accept that a whole food diet with minimal supplements, tailored to the individual, which likely requires vastly more preparation time and persistence to stick with could possibly be better than Isagenix. And that is about the time I lose interest and am in turn labeled closed minded.

I was overwhelmed a bit at first, but quickly figured out how it all worked. They include lots of literature in the kit so I was able to read more about the products and how they work and when I needed to take them. I was ready to begin! I started on a Thursday and I got up that day and weighed and measured myself (ugh!). The kit provides an area for you to record both your starting weight and measurements and even included a tape measure. I knew this weight had to go and I was excited to finally have some direction!
IF they lied they would get shut down. I could care less about what you think but, as a fitness competitor I do eat Really Clean! When I added these shakes into my program it only made my body respond so much better. I eat 6 times a day 2 of them being shakes. I am in the BEST shape of my life. I look and feel younger. Seriously, it enhanced the great nutrition I was already having. I love that you are all about whole foods, but wow. I know you will copy and paste your statement on answer me why they put those ingredients in. Matt already covered that. But I know someone will be contacting you from Isagenix soon. Its fine to have an opinion but full on disregard all the data that shows different about it being unhealthy is not right. The undeniable fact of so many people having results where health was turned around tremendously. With blood test work and everything . Not everyone is about weightloss and fat loss. Some are strictly for their last hope. And some is simply to supplement their already clean diet. Like me.
The only truly effective and comprehensive type of detox is a cellular detox also known as cellular cleansing. Cellular cleansing is designed to remove harmful toxins from the body where they are causing the problem: at the cellular level. While many people focus on eliminating toxic food, which is important, but there are many other toxins that people encounter that are not food related. A cellular detox doesn’t just focus on removing toxic food; it looks at all the potential toxins a person encounters on a daily basis and aims to remove them as much as possible from the body and environment. Before a person begins a cellular detox, it’s important to know what the potential toxins are and where they originate.

I would also like to share that I’m new to Isagenix (a couple weeks) AND I agree with you on some of the product ingredients. I even wrote an email to their support about their use of Palm Kernal Oil, not because of the ingredient itself, but because there’s a lot of controversy surrounding the areas where it’s grown. I’m not here to defend Isagenix. As I mentioned earlier, I agree. I read one comment earlier in which the person eluded to ISA as a transition. I would have to say that though it’s a shame some of these ingredients appear on some of the products, I’m happy to help some people take a step in the right direction. My mother for instance, addicted to coffee and sweets, can’t stand the thought of veggies, let alone raw and just in general practices poor eating habits. Yet, she’s feeling better already with ISA. Is it perfect? I’m not saying it is. I do hope, however, that it inspires her and other family members to continue on a path toward greater health and understanding of nutrition. But then, that’s not what what your blog post was about. It wasn’t created to argue the transitions of those in poorer health. It was simply created as an en devour into questionable ingredients. I will continue using it personally even, but I do so as part or a larger plan of general healthy eating practices. Are those practices perfect? No, sadly they aren’t. Personally, I’m doing the best I can, and the feedback I’m getting from family is that they’re feeling better. Is it a perfect solution? Again, nope, but it is a stepping stone towards one in my opinion. I will still also to encourage my family and friends to eat as organic as possible.
I cheated, and I hate myself for it. I drank a half a cup of a chai latte with skim milk. (I can’t even believe I’m saying this.) Rewind two weeks ago, and I was drinking grande-white-chocolate-mochas-with-whole-milk-and-whipped-cream on the daily; sometimes even twice a day if I wanted a sugar high mid-afternoon. The culprit on day 7: an outing with my friend, Stephanie. You can have green tea on these cleanses, but the café we went to didn’t have such a thing. I drank the chai latte reluctantly, guilt-ridden, and hurting (mentally) later. I felt like I had failed. No will power here.
I wrote this Isagenix review because I do not want you to fall for meal replacement shakes, for protein bars, or otherwise gimmicky foods. These companies produce cheap, toxic products and push them off on people as healthy alternatives (to what exactly I’m not sure). Instead, watch my video on how to make a protein shake that is not only unprocessed but actually good for you.
To use myself as an example, in a period of four months at age 21, I lost 18kgs and had my body to less than 4% body fat, when eating McDonalds at least twice daily, while training intensely for Senior football. This is why I laugh so much, as am I to assume that consumption of McDonalds leads to weight loss and health? Absolutely not. I could leave it at that, but what I failed to mention is that my lack of a nutritional diet led me to become seriously ill and bed ridden for over two months which nearly cost me my life. True story. For $50 a person could exercise regulary and have a diet consisting of vitamin supplements and water which would result in immense weight loss, but it is not a legitimate healthy option either, and would almost definitely leave you seriously ill as well.
There is absolutely no rationale for the particular combination of ingredients in their products. They have LOTS of different products, and have included just about every nutrient and herbal remedy in existence: 242 of them! Some of these we know to be useless, some are potentially harmful, and we have no idea how the particular ingredients in the mixtures might interact for better or for worse.
Listen in as Dr. Eric Gumpricht reviews the details of the clinical study using Isagenix products that was performed by researchers at UIC. This study has been published in two prestigious academic journals and recently earned recognition at a renowned scientific conference. The science supports what we have known all along–the Isagenix 30-Day Cleansing and Fat Burning System works!
If they’re so great, you shouldn’t feel the need to ‘report’ anyone. People are welcome to make their own opinions on the subject and she wants people to be informed is all. We all own a brain and while most of us use it to make good choices, some make more informed choices. I personally would never put something from a can into my body, or my families body, but then I guess that’s because they’re my family and not yours. Not really sure why people are so passionate about a diet supplement…maybe because there is money involved. I know a large number of people in my town who have used it and only two have kept weight off and they are selling the product. Both have ‘fallen off the wagon’ as well. Another woman was over 400 pounds, took some weight off and put it all back on…most likely because of personal choices, of course. But healthy eating and exercise, again, in my opinion, are the best way…life style change, not change in a can. Also, what happens to all of the extra vitamins? They have to go somewhere right? kidneys? liver? I would be concerned

Your comment on nonfat dry milk confuses me as you’re saying it’s denatured protein. This product, as it states in your heading, says ‘Low heat nonfat dry milk’. What I know about ‘low heat’ dry milk is that is classified as ‘Grade A’ or ‘Extra Grade’ and is required to contain a minimum 6.00 mg of undenatured whey protein nitrogen. This not classed as denatured. In addition, the theoretical ‘oxidised cholesterol’ contained in nonfat dry milk is negligible, particularly as in this instance low heat nonfat dry milk is not the product’s main ingredient. You say are sceptical about the pasture-fed cows but there is no evidence to suggest it is sourced from anywhere else. If your grocer tells you their spinach is locally grown and organic, do you follow the delivery van back to farm to see if they’re telling the truth? Do you stand in the farms and factories and watch the process of each and every product you buy to make sure they are doing what they claim? Who does that? We are all at the mercy of whatever our food labels and sellers tell us, along with some government rules and regulations to keep them in check.

You may be tempted to reach for the meds, but medicating with vitamins from whole foods—blueberries in particular—is a much better, all-natural option to perk-up a compromised immune system. In fact, you can think of each sweet little blueberry as a pill that’ll make you feel a whole lot better. Oregon State University recently took a look at over 400 compounds for their ability to boost the immune system, and the study revealed blueberries as a standout due to a compound called pterostilbene. Goodbye Pepto Bismol, hello Pterostilbene! Bored with plain blueberries? Try any of our 50 Best Snacks for Weight Loss for nourishing eats that are also delicious.
Dr. Harriet Hall writes more below about the junk science behind Isagenix. In short, there are no proven benefits to using the Isagenix products. Users of the products may offer anecdotes about their success with them, but that is not the same as having independent scientific studies supporting such claims. Of course, Isagenix prohibits reps from making medical claims about the products, but such a prohibition never seems to stop the distributors in any company.
