About Quest shake

Quest Protein Powder shake is a meal replacement available in Cookies and Cream, Salted Caramel, Chocolate Milkshake, Vanilla Milkshake, Banana Cream, Strawberries & Cream, and a Multi-Purpose flavor. The company (Quest Nutrition) fails to add much information about what the benefits are of this shake, other than it’s meant to be a tasty shake mix.

The do add a video that mentions Quest supplements offer the full range of macronutrients. Though they don’t add many details about what their protein powder has to offer. It’s clear the company makes products they feel appeal to sweet tooth’s, but without any added sugar that spikes blood sugar. The company is known to produce low glycemic foods with artificial sweeteners. Is there any benefit to this brand? What kind of results can be expected?

Quest shake Nutrition Facts

In this review, we will be referring to the vanilla quest shake flavor.


No calories come from fat; it’s a 100 calorie per serving protein drink. This is a low amount of calories.


Each serving provides 22 grams of the following:

Whey Protein Isolate: Quick absorbing protein extracted from the cheese making process. It has all the amino acids, and it’s around 90% protein by weight. Usually, Whey Isolate is mixed with Concentrate in order to provide both fast and low acting protein.

Micellar Casein:  Dairy protein extracts which are found in around 80% of the protein content in milk. It promotes a clot in the stomach, and it allows for a slow-acting amino acid source. This form of protein is considered a generic ingredient since it doesn’t reveal exactly what kind of protein is provided.


There’s less than one gram of fiber, this means any and all appetite suppression has to be left to the protein. Also, the quality of fiber comes only from thickeners which are often inside processed foods. This reduces the overall quality since it’s a cheap source that may potentially cause side effects.

Vitamins/Minerals/Superfood Blends

Another pretty shocking detail about Quest Protein Powder shake is that there are absolutely no vitamins included on the label. The best meal replacement shakes will be loaded with daily vitamins that you need for a healthy lifestyle. There are a few minerals listed but there are very low amounts of them.

You will literally be replacing your meals with this shake – yet it doesn’t contain even close to the amount of nutrients that you would hope to get from a good, healthy meal. In addition, the shake does not contain any other added nutrients or ingredients that would further boost the health potential, like superfood blends, digestive enzymes or probiotics.

What this says about Quest shake is that it is an extremely simple shake that is not well-balanced for overall health or long-term use.

Sugar/Sweeteners: The Potential Dangers of Sucralose

Though the Vanilla Quest Shake has 0g of sugar (which is ideal for a meal replacement shake), it uses an artificial sweetener, sucralose (Splenda).

We definitely do not applaud this choice of a sweetener, and whereas people might think they are making a better choice for their health by avoiding sugar, studies show that artificial sweeteners are just as bad, if not worse for both your health and your waist line.2

Sucralose may have many negative consequences from use, including that it can potentially reduce the beneficial bacteria population in your gut, which can lead to faulty digestion and weakened immunity, resulting in reduced overall wellness.

Some of the side effects seen from using Splenda include weight gain, GI problems, migraines, blurred vision and even seizures.

Another Controversial Ingredient: Carrageenan

Quest Protein Powder also includes carrageenan, a thickening agent derived from red algae or seaweed found in many different types of foods including some yogurt, dairy alternatives (like almond and coconut), ice cream and protein powders. The problem is that carrageenan is a very controversial ingredient that has increasingly been linked to disturbing health problems.

Carrageenan cannot be digested and it has no nutritional value, but while many parties claim it’s safe for use in foods, others clearly state otherwise. According to The Cornucopia Institude, animal studies have shown that food-grade carrageenan can cause gastrointestinal inflammation, intestinal lesions, ulcerations and even malignant tumors.3

Even if it is still approved for safe use in foods, the evidence clearly shows that this ingredient can be detrimental to your health and it would be wise to avoid it.

There’s a limited amount of micronutrients, and there’s not much fiber added. Also, the quality of the protein is mixed with one high quality source, and another potentially damaging protein.  Since the company fails to provide any benefits of what the protein powder has to offer, it’s unknown what the expected benefits are meant to be.

Final Thoughts

Not much information is provided by the manufactures. There’s a lack of key nutrients and much of the ingredients are commonly found in other protein shakes. Customers have complained about the artificial sweetener, and the overall lack of quality for the price. There’s also been concern over the taste and lack of consistency.  Clinical studies have shown that some of the additives can potentially cause damage and increase the risk for obesity.
