I Do Kay Pharmacist Malaysia Blog Isagenix Isalean Shake Review

What is in a Isagenix Isalean Shake?

I can’t tell you all how many times I have been asked to review this protein shake (a damn lot!) again and again by my patients and clients. But sorry guys… this is the other shake that I would not buy…

But before I straight dive into the whys… Let me just briefly go through with you what is Isagenix IsaLean Shake all about. 🙂

Isagenix company claimed that their Isagenix IsaLean Shake is a nutritious, balanced meal replacement clinically tested to promote effective, healthy weight loss and lean muscle building protein shake. It’s a low-glycemic shake with energy fueling carbohydrates, good fats, vitamins and minerals, and 24 grams of high-quality protein, with:

  • superior branched chain amino acid profile
  • active enzymes to help ease digestion
  • essential trace minerals
  • natural ingredients with no artificial flavours, colours, or sweeteners
  • no trans fat

ISAGENIX SHAKE Sounds pretty good huh… but

having all these benefits been said. Are Isagenix IsaLean Shake really that perfectly healthy? Would Isagenix IsaLean Shake never bring any health issues to our body when it was religiously be used? Is Isagenix IsaLean Shake “Protein Shake With Integrity”? Were Isagenix company just another chains with “healthy marketing” pitches telling the truth, or lying through their bottle wrappers? Let’s dig further…


Now, first of all, by looking into the long ingredients list of Isagenix IsaLean Shake… how many of these ingredients can you all understand and imagine? Yes? No? What about from the outside bottle of Isagenix IsaLean Shake?

  1. What is the first 3 ingredients on their food label?
  2. Is it organic, free of pesticides, and grass-fed?
  3. Does it contain soy protein mostly?
  4. Is it GMO-free?
  5. How is it processed?
  6. Does the processing allow it to retain its nutritional quality, its vitamins and minerals, or being denatured?
  7. Does it contain a lot of additives?
  8. Does it contain artificial or refined sugars?
  9. Does it have heavy metals?
  10. Does eating refined foods versus whole foods make sense?

These are the essential steps and questions to know what is in your hand before buying any protein shakes and drinks! It is incredibly essential to know what you are eating, buying, where it is from, how it is produced, is it genetically modified (GM)? If there is no detail informations, call to their customer care line and find out more! Are their staffs and nutritional experts friendly to answer your queries as a consumer?

why ISALEAN SHAKE is another popular one that i wouldn’t buy…

Well, Isagenix IsaLean Shake “seems pretty clean” but the reasons that I would not buy it is that this protein powder is NOT organic certified and NOT non-GMO Project Verified. With these 2 simple condition, there is a chance that some of the ingredients such as fructose are derived from GMOs!

but their website states their whey from nz cows fed!

Yes, while their website states their whey comes from New Zealand cows fed on a pasture, they readily admit, “We have also sought other suppliers in Australia and the U.S. who meet the same standards for dairy protein“. Well, the matter of fact is that without the certified organic or certified grass-fed label, there is the higher chances that the cows were raised with some GMOs feed.


  • The amount of sugar in this shake is pretty high too at 11 grams per serving, which is almost 3 teaspoons!
  • Although this powder is filled with vitamins and minerals, these don’t come directly from real food.
  • The ingredients within the natural flavours in this shake are not identified on the label.

Why identifying it is important? Well, flavours can contain up to 100 ingredients, including “synthetic chemicals such as the solvent propylene glycol or the preservative BHA” as well as GMO-derived ingredients. Hence, clearly labelled is critical in this case.

but they are still consider “safe” to consume…

Well, not with these ingredients at least… please! >> Fructose.

Some people might think that I am a no-sugar diet fan. In fact, this is NOT true. I do allow up to 5 grams of sugar in my protein shake from sugar alcohols. Sugar forms and their source matters. I don’t like the idea that people are getting that 5 grams of sugar from agave, high-fructose corn syrup, fructose, artificial sweeteners, etc… here’s why:

the idea of “healthy sugars” is crazy

Well, I hate to break you here… but the idea of “healthy sugars” is crazy. It’s a hype. They don’t exist! I am sorry. Some people argue that agave and honey are natural. Yet, in fact, natural or not, it could not be worse for you. Not all sugars are created equal. For example:

  • Agave is higher in fructose than high fructose corn syrup.
  • Honey, however, could have some homeopathic benefits for the allergies, strengthen your immune system, help you handle things better… but this honey needs to be grown organically raw with about a half-teaspoon a day. Not more than that.
  • You don’t want drinks whose names contain the words nectar or cocktail. Both terms are code for “we added even more sugar”.
  • Product with the word light on it because that only means they added water and artificial sweeteners.

the myth of fructose. the worst sugar of them all

Watch out for your protein shakes sugar content. Avoid protein shakes with fructose. Some people argue that, well… all fruits contains fructose. What’s bad about it?

You don’t need to worry about the fructose found in whole fruits and vegetables that you consume. Now let’s get ONE thing straight: fruit is fabulous IF you were eating the right kinds and the right amounts. I want you to choose those with high fiber and low glycemic index in this case. Berries are the best. 1 to 2 pieces of low GI fruit per day should be it.

Ironically, the problem is when you start drinking juice or consuming high-fructose corn syrup or agave sweetened “health foods” with low glycemic index. This approach gives you super high levels of fructose and sets you up for weight gain and other health risks. 

problem #1

The biggest problem with fructose marketing is that “health foods” companies and conventional healthcare professional states that fructose has a low-glycemic index (meaning that it doesn’t raise your blood sugar). Well, of course it doesn’t raise! That’s because fructose is metabolised differently from glucose. This brings serious problems to a lot of my patients. They think that because fructose are low in GI (glycemic index), they can then consume a lot of it and still thinking that it can help with their weight management regimen. This lead to problem #2.

problem #2

Fructose doesn’t trigger your brain to release leptin, the fullness hormone. This is bad news to your weight loss journey. Because this means that you can consume an enormous amount of fructose calories without your brain ever realising that you are full! Your blood sugar spins out of control, you develop leptin resistance (fail of feeling fullness), and you end up loading your body up with calories!

problem #3

100% of fructose you consume goes straight to your liver, which stores a lot of it as fat and converts the rest into free fatty acids, triglycerides and cholesterol, which then turn into fat and artery-clogging plaques.

problem #4

Fructose can exacerbate high blood pressure. In fact, researchers use fructose on lab rats if they need them to become hypertensive (high blood pressure) for a study!

problem #5

Fructose can elevate uric acid, which led to gout. An over abundance of fructose first found it’s way into our diets when we learned how to genetically modified corn. As a result, it became very cheap to produce high-fructose corn syrup, sweetener and preservatives that is in just about every processed food you can think of! Not to mention that fructose, is one of the main ingredients in full-sugar sodas.

problem #6

Fructose can cause small bacterial intestinal and yeast overgrowth, kidney disease and insulin resistance. Fructose can poke holes in your small intestine creating leaky gut.

problem #7

Fructose makes you fat and contribute to the incidence of obesity in humans. One study estimated that high fructose corn syrup accounts as much as 40% of caloric sweeteners. The study look at both short term and long term effects of high fructose corn syrup on body weight, body fat and triglycerides in rats. The rats fed with high fructose corn syrup found gained overall weight and fat around their waists and had higher triglycerides than either rats ate the chow with sucrose.

problem #8

Fructose just frustrates your weight loss efforts. It affects your fat burning ability. In fact, counting calories is really not important in weight loss. Here’s what I meant. According to Dr. Robert Lustig, a professor of pediatrics in the Division of Endocrinology at the University of California, San Francisco, 1/3 of the fructose calories ends up getting stored as fat.

Fructose vs glucose: For example, if you consume 120 calories of fructose, 40 calories are stored as fat. Meaning that fructose is 40 times more likely than any other sugar to make you fat. Whereas, if you consumed 120 calories of glucose, only 1 calorie is stored as fat 🙂 These corn syrup, fructose, fruits juices calories are on a fast track to turn into fat. Not a pretty picture 🙁

Hence, in conclusion, do you know someone still consuming protein powders with terrible ingredients? If so, please share this post with them and spread the word! If you still confused on protein powders… just remember, if your protein powder is not certified organic and contain fructose and soy protein (that I had discussed on my sculpt protein reviews blog post), it’s not worth putting it in your body – especially on a regular basis. Period.
