Quest Protein Powder is a protein supplement shake blend that offers a high dose of protein with some essential macronutrients, all designed to increase muscle gains in the gym while tasting delicious, but will it work like that?
British Journal of Sports Medicine – “Dietary protein supplementation significantly enhanced changes in muscle strength and size during prolonged RET [resistance exercise training] in healthy adults.”
Frontiers in Nutrition – “There is robust evidence which shows that consuming protein pre- and/or post-workout induces a significant rise in muscle protein synthesis.”
Dovepress – “Whey is one of the high-quality sources of protein with a higher proportion of indispensable amino acids compared to other sources. Its high leucine concentration makes whey an optimal protein source to maximize muscle protein synthesis (MPS) and to attenuate muscle protein breakdown at rest and following exercise.”
The Quest brand is known for its above-average tasting products, including bars and powders, that deliver 22 grams of protein per serving.
Of the 100 calories per serving, none of these come from fat, which makes the brand particularly appealing to those trying to cut excess body fat. The brand does use dairy or dairy derivative ingredients in their products and is not meant for individuals following a vegan or vegetarian-based diet.

How Did Quest Protein Powder Start?
The Quest Nutrition brand is the producer, creator, and manufacturing company of Quest products, founded in California in 2010. The founder of Quest Nutrition, Shannon Penna, set out to create a protein-based snack line in 2010 that focused on nutrition, convenience, wellness, and great taste.
The brand launched its first two flavors: Vanilla Almond Crunch and Peanut Butter Supreme. In need of more space, the company could open up operations to a tiny commercial kitchen rented by the hour.
Initially, they made Quest Bars, their first product, using rolling pins and hand-held knives. With the first profits the company received from using fitness models as advertisers, Quest and the company purchased their first industrial-sized mixer in 2011.
Unfortunately, the machine inevitably failed, and the team went back to producing the product by hand. In 2012, the company released new flavors, including chocolate chip, and in the same year, GNC, the recognized supplement distributor, awarded Quest and company with “Protein Bar of the Year.” The brand was named the honor the following year as well.
The brand expanded to Vitamin Shoppe and Bodybuilding.com in 2013 that they were able to move to a 100,000 square foot state of the art facility. Their whole story can be found on the Quest Nutrition Website, which details the incredible passion the company has for its products. Finally, in 2015, a line of Quest protein powder was released for its versatility in drinks, smoothies, and baked goods.

Quest Protein Powder Ingredients
Quest Protein Powder ingredients include:
Protein Blend (Whey Protein Isolate, Micellar Casein, Milk Protein Isolate
Whey Protein Isolate is a rapidly absorbing protein extracted from the cheese-making process of dairy products.
It contains all the amino acids, and it maxes out at around 90% of protein by weight.
Typically whey isolate is combined with whey concentrate to provide both fast and slow-acting protein.
Micellar Casein is also a dairy-based protein extract found in around 80% of the protein content in milk.
Micellar casein promotes the formation of a gel in the stomach that helps slow digestion.
Additional Quest Protein Powder Ingredients
Steviol Glycosides (Stevia)

Quest Protein Powder Benefits
A significant claimed benefit of Quest Protein Power is that it comes in different flavors and can be added to many recipes and dishes, like loaves of bread to soups, to increase your daily protein intake.
There is also a recipe booklet included with each canister. As far as nutritional benefits, one scoop of Quest protein powder includes, according to USDA recommended daily allowances:
There are no specific clinical trials that document any results from using Quest protein powder specifically. However, the effects of ingesting protein in powdered form have been well-documented in numerous scientific studies.
Studies show that serum amino acids responsible for muscle synthesis increase in response to protein ingestion. The two most widely used types of supplemental proteins are whey and casein.
A recent study published in the Journal of the International Society of Sports Nutrition showed the serum amino acid response to whey protein elicited a rapid increase of amino acids.
Essentially this shows that these two types of proteins, when used together, create a fast and slow release and absorption of serum amino acids, similar to simple and complex carbohydrates. Other studies have shown similar results in the peak plasma levels of amino.
Consumer reviews for Quest protein powder are mixed but are overall positive. Consumers who gave the powder positive reviews said the product had a good taste, mixed easily with liquids, and tasted good even when mixed with just water.
Negative reviews stated the product was too sweet and foamy, had a gritty texture.
Heather Mangieri, registered dietician and spokesperson for the Academy of Nutrition and Dietetics states that studies suggest consuming protein may prevent the secretion of ghrelin, often referred to as the hunger hormone. Ghrelin is believed to be responsible for sending signals to the brain that the stomach is full.
Lauren Antonucci, a registered dietician and board-certified sports dietician says that many people have trouble getting adequate amounts of protein in their diet.
She confirms that adding protein powder to your diet can help fill in deficiencies in the amount of protein people consume and the amount of protein they need. Also, Antonucci says that many people who work out need additional protein to meet the increased demands of muscle synthesis.
Potential Quest Protein Powder Side Effects
There have been some negative side effects reported from using Quest protein powders. These mainly include nausea and stomach upset, ranging from mild to severe.
There are no direct warnings on the Quest protein powder label. However, several concerns are surrounding some of the individual ingredients in the product. The two ingredients of major concern are sucralose and carrageenan, both of which have been shown to pose possible health risks in studies.
Major health concerns are rising for the artificial sweetener sucralose, most commonly known to consumers by the trade name Splenda. Sucralose is a synthetic sweetener created by chemically altering standard table sugar at the molecular level.
While initial studies had shown sucralose to be safe, recent studies have found that sucralose can produce many negative effects. These include potentially reducing the number of beneficial bacteria in the gut, leading to improper digestion and a weakened immune system.
Other side effects attributed to sucralose include weight gain, impaired vision, migraines, inflammation that can increase the risk of serious diseases.
Another controversial ingredient is carrageenan. This substance is produced from algae or seaweed and has been regarded as safe in controlled amounts.
Carrageenan is used as an emulsifier and thickening agent and also used as a “natural” laxative. Carrageenan is found in many types of foods, including yogurt and dairy alternatives such as almond and coconut milk, ice cream, and is one of the main ingredients in many protein powders.
One issue with carrageenan is it cannot be digested, so it has no nutritional value. Some studies have suggested that food-grade carrageenan can cause health issues such as gastrointestinal inflammation and intestinal lesions.
The Clean Label Project is a nonprofit organization devoted to transparency in product labeling. Protein supplement manufacturers frequently use terms such as “natural” and “plant-based” or “proprietary-blend” to market their products.
The CLP tested more than 130 of the best-selling protein powders to look beyond manufacturers’ labels. For rating purposes, the Clean Label Project focused on BPA, heavy metals, and other contaminants and nutritional ingredients to compute an overall score for each product.
Because of the significant harm posed to consumer health, the CLP study weighted heavy metal concentrations at 60 percent of the total score.
The Clean Label Project study found that many top-selling protein powders contain possible dangerous levels of chemicals and heavy metals, including arsenic, cadmium, lead, and mercury.
The study also found toxins like BPA (bisphenol A), a chemical used in some plastic containers and food can liners. An article published by Consumer Report named Quest protein powder as one of the worst offenders for these substances.
Various law firms are currently using the Clean Label Project study on protein powders in examining the feasibility of class-action lawsuits.
Anthony Dugarte MD shares, “This product helps avoid a common protein powder pitfall – high amounts of added sugars which can be harmful to certain populations. This illustrates the need to understand ingredient label basics as well as including a physician in the decision to start a new supplement.”
Any Quest Protein Powder Lawsuits?
There are no current lawsuits filed against Quest in regards to their protein powders. However, the company has been named in lawsuits alleging misrepresentation of the ingredients in their protein bars.
This seems to coincide with a growing number of supplement companies being accused of selling protein supplements that have been adulterated with cheap fillers being passed off as protein.
The U.S. Food and Drug Administration requires that all dietary supplements be accurately labeled regarding their ingredients, including the amount of protein content.
The FDA expectation is that companies will evaluate their product’s protein content from actual protein sources and not other nitrogen-containing substances. This is because substances like individual amino acids that won’t survive the gut can cause lab tests to show the product to have a higher protein content than what the bioavailability of useable protein is.

Another meal replacement shake powder that claims to be clinically proven to support lean tissue growth and weight loss. However, the company does not provide any details on the referenced studies.
Isagenix Isalean markets itself as a superior meal replacement shake with high nutrients and a total of 24 grams of protein and 23 vitamins and minerals. The company says the shake is made without hormones or antibiotics and is low in fat and can be made with milk, juice, or water.
This company produces a line of weight loss food products, including various meal replacement drinks.
The company emphasizes their drinks should be incorporated into a comprehensive diet plan that includes their entire lineup of products for optimal weight loss results.
Vega One Shake
This protein powder shake mix is designed for vegetarians and vegans. It is claimed to be made from organic whole foods ingredients and plant-based proteins with antioxidants and probiotic properties.
The brand promises to provide all the needed nutrients for weight loss and is marketed as a wholesome gluten-free shake. Vega One claims that plant-sourced ingredients will potentially reduce the incidence of chronic disease. However, the company proves no scientific data to back up this claim.
Gold Standard Protein Powder
This protein powder uses whey protein isolates as its primary protein source.
Gold Standard powder claims 24 grams of “the purest, muscle-building protein” per serving, with low fat and lactose content and no artificial sweeteners.
Quest Protein Powder Claims
Quest Protein Powder claims to be made from only the highest quality protein sources and has a higher percentage of useable than other protein powders.
Quest claims to be an ideal protein supplement for your post-workout regimen to boost muscle growth by providing 23 grams of protein in each scoop of powder. However, the company does not break down the percentages of whey vs. casein.
The product label indicates that the powder contains less than one gram of active carbohydrates, or sugars, in each serving, providing a higher protein to calorie ratio than other protein supplements.
This, the company claims, will provide the maximum benefits of increased protein intake without a lot of added calories.
Pros and Cons
Protein does curb hunger and can promote weight loss.
