Whey protein concentrates are created by pushing the protein source (milk, whey, etc.) through a very small filter that allows water, minerals and other organic materials to pass though.
Meanwhile, the proteins, which are too big to pass through the filter, are collected, resulting in protein powder.
Milk Protein Concentrates (MPCs) and Milk Protein Isolates (MPIs) are manufactured by membrane filtration through which dairy proteins are isolated from fresh skim milk.
Among proteins they hold a relativey high biological value and are rich in calcium, have good heat stability and a excellent flavour profile.
This is the purified form of whey protein concentrate.
Basically, the protein that is collected as protein concentrate is purified again to reduce the levels of carbohydrates and fats.
Additionally it absorbs more quickly than any other protein.
Maltodextrin is a white powder often used in processed foods as a thickener or filler since it’s fairly inexpensive, as well as in pharmaceuticals as a binding agent.
You’ll find it in canned fruits, snacks, cereal, desserts, instant pudding, sauces, and salad dressings.
Since it contains fewer calories than sugar, it’s also found in sugar substitutes, such as Splenda or Equal.
One of an array of factory-made additives, cellulose is increasingly used by the processed-food industry to thicken or stabilize foods, replace fat and boost fiber content, and cut the need for ingredients like oil or flour, which are getting more expensive.
Cellulose is especially popular because it can be used in many ways in food and is relatively inexpensive.
Oat fiber a great source of fiber in shakes.
Oats contain more soluble fiber than any other grain, resulting in that full and satisfied feeling longer.
is a type of starch that isn’t fully broken down and absorbed, but rather turned into short-chain fatty acids by intestinal bacteria.
Fructooligosaccharides are a group of oligosaccharides, or connected simple sugars. These simple sugars are fructose molecules. Fructooligosaccharides are commonly used as a sweetener and as a prebiotic dietary supplement. They can be used to ferment certain good bacteria in the intestines and in small doses are not typically harmful.
However, side effects of excessive fructooligosaccharide use include intestinal problems, bloating, gas, or diarrhea. It is an indigestible carbohydrate, so that high intake can cause trouble in processing it through the body and into the waste system. There is some scientific literature suggesting that over-consumption might hinder the ability of the beneficial bacteria to survive in the gut.
Xanthan gum is a sugar-like compound made by mixing aged, or fermented, sugars with a certain kind of bacteria.
In manufacturing, xanthan gum is used as a thickening and stabilizing agent in foods.
Carrageenan are a family of linear sulfated polysaccharides that are extracted from red seaweeds. They are widely used in the food industry, for their gelling, thickening and stabilizing properties. Carrageenan can be found in many foods, even foods labeled “natural” and “organic.” It is widely used in dairy products (chocolate milk, whipping cream, ice cream, nonfat sour cream), frozen dinners, dairy alternatives (soy milk, coconut milk, almond milk), prepared poultry and cold cuts, nutritional drinks, and even infant formula.
The problem with partially hydrogenated soybean oil is the trans fat it contains. The other problem relates to the health hazards of soy itself. And an added hazard factor is the fact that the majority of both corn and soybeans are genetically engineered.
Dicalcium phosphate is commonly added to food as a dietary supplement for a source of calcium and phosphorus.
Due to its fairly high concentration of calcium, it should be used with caution by breast feeding mothers and those suffering from lung disease and kidney stones.
Chromium is an essential trace mineral that helps the hormone insulin to function at its full potential. Nicotinate and picolinate are two forms of chromium. Proponents of the picolinate form claim that it lowers cholesterol, burns body fat, and increases life span.
The public apparently caught on that partially hydrogenated oils were unhealthy; so now the FDA requires labeling for trans fat content, BUT only if it contains more than .49 g per serving, AND only if it comes from triglycerides! Not too difficult to get around that rule…simply decrease the serving size, or disguise the trans fats somehow…
Of course, big industry doesn’t want us to know that they’re poisoning us…so, they exploited the loophole. They started using monoglycerides and diglycerides so they aren’t required to label the food as containing trans fats.
Monoglycerides and Diglycerides are still manufactured, just like partially hydrogenated oils, and they still contain dangerous trans fats. Trans fats that aren’t required to be reported on the labels. Trans fats that are still dangerous to your health. Trans fats that are causing our children to develop diabetes and heart attacks.
The definition of natural flavor under the Code of Federal Regulations is: “the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional.”
The search for “natural” sources of chemicals often requires that a manufacturer go to great lengths and expenses to obtain a given chemical. For this reason, synthetically produced flavors are frequently used in foods and beverages.
Artificial flavors have been known to cause an array of health problems such as chest pain, headaches, fatigue, nervous system depression, allergies, brain damage, seizures, nausea, dizziness and many more.
Magnesium phosphate is a general term for salts of magnesium and phosphate appearing in three forms: ⁕Monomagnesium phosphate ⁕Dimagnesium phosphate ⁕Magnesium phosphate tribasic Various forms have been used as laxatives and antacids.
When a manufacturer wants to ensure a baked good will rise, it may include calcium carbonate, which, as a leavening agent, promotes rising. Others use the additive as a calcium source. The uses of calcium carbonate are almost infinite and it can be found in almost all kinds of foods from dried fruits to canned sardines, also in frozen foods, cereals, aromatized beverages and processed meat and fish products
Milk naturally contains calcium phosphate.
Foods such as breads, cereals and drink mixes also commonly contain calcium phosphate.
Manufacturers also frequently fortify packaged foods and drinks with calcium phosphate.
Sodium ascorbate is a more bioavailable form of vitamin C that is an alternative to taking ascorbic acid as a supplement.
Ferric orthophosphate, also known as iron phosphate, is an inorganic chemical containing iron. It is a mineral that is added to nutritional supplements to treat anemia, or iron deficiency.
Ferric orthophosphate also has other food and medical uses as well as uses outside of food and medical treatments.
Dl-alpha tocophyl acetate is a form of vitamin E.
Niacinamide and niacin are slightly varying forms of vitamin B3.

Zinc oxide is added to many foods as a source of zinc.
D calcium pantothenate is a synthetic substance made from pantothenic acid and sold as vitamin B-5 supplements.
Manganese is a mineral that is found in several foods including nuts, legumes, seeds, tea, whole grains, and leafy green vegetables. It is considered an essential nutrient, because the body requires it to function properly. People use manganese as medicine. Manganese is used for prevention and treatment of manganese deficiency, a condition in which the body doesn’t have enough manganese.
Pyridoxine is one of the compounds that can be called vitamin B6, along with pyridoxal and pyridoxamine.
Cupric oxide continues to be the principal source of Cu used in vitamin-mineral supplements for humans.
Thiamine hydrochloride is a white, crystalline hygroscopic food-additive used to add a brothy/meaty flavor to gravies or soups.
It is a natural intermediary resulting from a thiamine-HCl reaction, which precedes hydrolysis and phosphorylation, before it is finally employed (in the form of TPP) in a number of enzymatic amino, fatty acid, and carbohydrate reactions.
Vitamin A acetate is a natural form of vitamin A that is commonly used to vitamin supplements.
Riboflavin also known as vitamin B12. This is naturally found in many foods and it is added to many protein shakes.
Chromium chloride is the naturally occurring trivalent variety of the mineral chromium found in many food types and synthesized supplements.
Most commonly referred to as chromium only, chromium chloride is a human dietary requirement.
Folic acid is a B vitamin. It helps the body make healthy new cells.
“Folic acid” and “folate” mean the same thing.
Folate is found naturally in some foods and folic acid is a manmade form of folate.
Since 1998, folic acid has been added to most enriched bread flours, cornmeal, pasta, rice, and other grain products in the U.S. and Canada.
This was done to help prevent spina bifida and anencephaly, two birth defects that are caused in part by too little folate in a mother’s body around the time her baby is conceived.
Biotin is a water soluble vitamin and another name for vitamin H.
Biotin is associated with many health benefits including the metabolism of fats and amino acids, as well as the production of new cells.
Sodium molybdate is a chemically altered form of the mineral element, sodium.

Sodium molybdate use in food may have some benefits, as well as some side effects.
Potassium iodine is an organic compound that is commercial sold as white table salt.
Sodium selenite, another name for selenium, is a mineral essential for optimal health, even though your body only needs small amounts.
Sodium selenite is present in plant foods, in some meat and seafood, and in supplements.
Selenium is touted as a treatment for a variety of diseases because it’s an essential component of glutathione, your body’s most potent natural antioxidant.
Cyanocobalamin is a man-made form of vitamin B12 used to prevent and treat low blood levels of this vitamin. Most people get enough vitamin B12 from their diet. Vitamin B12 is important to maintain the health of your metabolism, blood cells, and nerves. Serious vitamin B12 deficiency may result in a low number of red blood cells (anemia, stomach problems, and permanent nerve damage.
Dairy milk with zero perfect fat.
Caution! If you take certain vitamins made by GNC or Centrum (as well as hundreds of other companies), you are eating titanium dioxide. This is an ingredient for which no long-term safety testing on humans has ever been conducted.
sthma, cancer, kidney disease, Alzheimer’s and fertility loss.
Several grocery and retail chains nationwide have banned any products containing sucralose, the latest being Whole Foods. Watchdog groups are up in arms over artificial sweeteners like sucralose suggesting research on its safety is flawed and doesn’t account for how long-term use of the additives may impact health.
What’s in it?? Sucralose is a synthetic additive created by chlorinating sugar. Manufacturers say the chlorine in sucralose is no different from that in table salt. But in fact, the chemical structure of the chlorine in sucralose is almost the same as that in the pesticide DDT. Side effects may include head and muscle aches, stomach cramps and diarrhea, bladder issues, skin irritation, dizziness and inflammation.
Further research has shown that sucralose can cause shrinking of the thymus gland, an important immune system regulator, and liver and kidney dysfunction. A recent study by Duke University found sucralose reduces healthy intestinal bacteria, needed for proper digestion.
Just Google the “dangers of Acesulfame Potassium” and your screen will light up! What is it? It is a calorie-free sugar substitute, also known as Acesulfame K or Ace K. In the U.S., it is used in such products as candies, baked goods, frozen desserts, and beverages. Here’s the problem it’s highly highly controversial, especially as of late. Reported side effects: Long term exposure to methylene chloride can cause nausea, headaches, mood problems, impairment of the liver and kidneys, problems with eyesight and possibly cancer. Because of such recent controversy towards it’s safety and side effects it’s been banned at leading retailers, the most recent being Whole Foods.
GNC’s brand is a very strong and popular option in the health world, but that doesn’t necessarily carry weight when reviewing products. Just because the brand is heavily known, doesn’t necessarily mean they have the best meal replacement shake.
A quick look at the stand out qualities of GNC Lean 25 is that there are 3-types of whey in their blend. They focus on milk, whey isolate, and whey protein as the backbone of their ingredients. This foundation is high quality, but GNC adds some potentially harmful ingredients, which drops their rating down.
Acesulfame-K – This form of potassium salt contains methylene chloride, which is a known carcinogen. Other side effects that this ingredients causes includes nausea, headaches, mood alterations, liver and kidney dysfunction, ocular issues, and even free radical mutation (cancer).
Sucralose – This form of sugar can be a potential health risk. Some companies promote this as a harmless derivative of real sugar. Some clinical reports have linked sucralose consumption with gastrointestinal problems, seizures, dizziness, migraines, blurred vision, blood sugar increases and weight gain.
Protein Blend – There are only 9 grams of protein per serving, which falls well below many competitors. Furthermore, it contains 5 grams of sugar and 250 mg of sodium per serving, which is not favorable in a good meal replacement shake.
Artificial Flavors– The search for “natural” sources of chemicals often requires that a manufacturer go to great lengths and expenses to obtain a given chemical. For this reason, synthetically produced flavors are frequently used in foods and beverages. Artificial flavors have been known to cause an array of health problems such as chest pain, headaches, fatigue, nervous system depression, allergies, brain damage, seizures, nausea, dizziness and many more.
GNC Lean 25 offers a low cost entry into the meal replacement shake world, however, the blend and ingredients they are using is sub-par with what you may want in the best available product. We found just a few red flags to start with, but GNC also adds some other fillers, which makes this option less than ideal for those that want the best.
