Whey is a natural diary protein containing vitamins, minerals, protein, lactose and traces of milk fat. Most commercial whey supplements are derived from cow's milk, which is comprised of 6.25% protein: 20% in the form of whey. Whey protein supplements utilize the concentrated protein, eliminating the lactose and milk fat. Whey is a complete protein, meaning it contains all essential amino acids, which are vital to your metabolism, and to making your body function properly for good health.
No, while both are natural dairy products, milk contains ~6.25% protein that is comprised of 80% casein protein and 20% whey protein. In addition, milk contains lactose and fat (removed in skim milk). Whey protein is extracted from milk, leaving the lesser protein- casein- and eliminating most of the lactose and fat.
Proteins are the basic building blocks of life. Protein, and only protein, provides your body with the amino acids it needs to build, repair and rebuild muscles. Protein also provides the necessary components to keep your immune system healthy, make hormones, enzymes, skin, hair, nails, organs and blood. (Note the word protein comes from the Greek word "proteios" meaning of prime or of first importance.)
Several factors play critical roles in how much protein your body needs. Age, size (height and weight), metabolic rate, exercise level, stress factors (work, health status, viral or bacterial infection), your amount of sleep, and the quality and quantity of foods you eat, all play a role in determining your protein requirements. (7-12) Extensive research into human metabolic rates and how they are affected by age, activity and stress have been prepared over the last decade by leading physicians in hospital settings. (13) See the table below for estimates of your protein requirements based on your personal lifestyle/training goals.
|Lifestyle/Training Goal ||Daily Protein Needs |
|Stressed ||0.45 - 0.7g/lb bodyweight |
|Trauma Recovery ||0.9 - 1.4g/lb bodyweight |
|Dieting ||0.35 - 1.0g/lb bodyweight |
|Endurance ||0.7 - 0.9g/lb bodyweight |
|Power & Speed ||0.9 - 1.1g/lb bodyweight |
|Strength & Bodybuilding ||1.0 - 1.6g/lb bodyweight |
No, it's not true, since free-form amino acids are poorly utilized by the body for protein synthesis. To get the amino acids your body needs, consume protein in the form of peptides (the best method) or eat whole, intact protein. In fact, scientists have found that protein in the form of peptides is absorbed much more rapidly - as much as 237% faster - than free form amino acids or intact protein. (2)
Not only does whey protein improve nitrogen retention better than amino acids, research shows it also stimulates protein synthesis 119% better than casein. When 30 grams of whey protein were compared to 43 grams of casein, whey protein increased protein synthesis by 68%, while casein increased it by only 31%. (3)
Bodybuilders frequently consume 300-500g of protein per day for months - even years, yet there is no scientific evidence that this high protein intake causes kidney problems. In other studies, animals with high protein intakes for more than half their lifetime showed no kidney damage. (17) High protein intake may be hazardous only for individuals with abnormal kidney function or kidney disease. For the disease-free individual, the most serious concern with high protein intake is dehydration, because it takes a lot of water to metabolize protein. This is avoided by drinking 8 or more 8 oz. glasses of water a day.
A new study just looked at the effects of a high protein intake on markers of safety in 20 healthy resistance-trained males. The subjects were taking 1.3 grams of protein per pound of bodyweight 3.6 times greater amount than that recommended by the RDI. After 28 days the researchers concluded that the daily high protein intake had no untoward or negative effects on the immune system, renal and hepatic function nor did it induce ketosis or dehydration, thus it appears safe for short term daily intake (25).
Quite contrary to any thoughts of adverse effects, DESIGNER WHEY is used by many renal patients because it is low in phosphorus, potassium and carbohydrates, but is high in biological value, and can be mixed in a small amount of fluid and is easily consumed.
In order to achieve muscle growth while using protein powders you must "weight train" on a regular basis. A recommended workout for obtaining greater muscle definition is to exercise or train 3-4 days a week, rest prudently, avoid overtraining, and eat right. If you stick to this program, you may see results in as short a period of time as six weeks. Continuing this regimen for 48 weeks a year, for at least 3 or 4 years, will provide you the opportunity to attain the "big muscles" or improved muscular definition you are looking for.
No. While DESIGNER WHEY is derived from 100% whey protein, its formula is designed to produce even greater results. For instance, DESIGNER WHEY delivers a precise blend of three separate, partially pre-digested whey proteins that make up our Full Spectrum Whey Peptide Blend. Peptides have been proven in clinical science to be the body's preferred source of digestible nitrogen (26,27). DESIGNER WHEY is also glutamine enhanced, providing over 2 grams of moisture stable anticatabolic glutamine for every 2 scoop serving. In addition each serving contains ZinMag-6 a powerful blend of ingredients shown in clinical research to help increase performance, including improved strength, power, and recovery.
In a word- Results. The whey protein in DESIGNER WHEY Protein has produced bigger and better results than any other protein supplement in history. Not only is whey the easiest protein to absorb, it also lowers cholesterol and helps to build strong bones. DESIGNER WHEY is a complete protein containing all essential amino acids. And thanks to an advanced ultra-filtration technology, DESIGNER WHEY contains all the major fractions of whey as well as additional fractions with significant health benefits, including glycomacropeptides, which can aid dieters in curbing and controlling their cravings, and lactoferrin, which boosts the immune system.
Not true. Just by biological value alone, which signifies how much nitrogen is retained vs. how much is taken in, you know whey protein is digested and retained better than any other protein source. Just compare the biological value of whey (104) to casein (77) and you can see how inferior casein is, providing you with up to 35% less nitrogen retention. In fact one study that compared whey peptides to regular whey and free form amino acids showed that quickly digested whey peptides provided more nitrogen retention and better muscle gain than the other two corresponding mixtures (2).
APT™ - Full Spectrum Whey Peptides are DESIGNER WHEY's proprietary blend of a complete spectrum of very low, low, medium and high molecular weight whey peptides. These peptides make up the major and minor fractions of specially prepared whey protein.
Beta-Lactoglobulin (~55-60%) is the largest protein fraction of whey and rich in branched chain amino acids, necessary to fuel muscle growth.
Alpha-Lactalbumin (~15-25%) is a low molecular weight peptide that is easily digested allowing faster absorption and uptake into muscles.
Glycomacropeptides (~10-20%) stimulate the release of CCK, a hormone that signals the brain "you're full", helping to reduce your appetite.
Immunoglobulins (~1-2%), as the name implies, may help to bolster the immune system.
Bovine Serum Albumin peptides (~1-2.5%) are rich in the precursors necessary for the production of glutathione - the body's most important antioxidant. Research has shown whey protein increases glutathione levels in the body. (1)
Lactoferrin, lactoperoxidase and lysozyme (~1%) have antimicrobial properties.
Active Peptide Transport™ is DESIGNER WHEY's breakthrough formula in whey protein-peptide delivery. Active Peptide Transport is a new formulation that results in faster, more efficient absorption of whey peptides.
Fast protein absorption is important if you want to maximize your anabolic potential; significant scientific research has demonstrated that the faster a protein source is absorbed, the more protein synthesis is stimulated. (2,3) (Resulting in faster muscle growth!)
Active Peptide Transport was designed to do just this: provide faster and better protein-peptide absorption to stimulate protein synthesis and muscle growth.
All DESIGNER WHEY products are aspartame-free. Instead of aspartame, Designer Whey products use preferred non-nutritive sweeteners Acesulfame-K and/or Sucralose. Acesulfame-K or Sunett® brand sweetener is a calorie-free sweetener that includes intensive sweetening power (about 200 times sweeter than sugar), high purity and safety. Since it is not metabolized by the human body, it passes through the digestive system unchanged. For more in depth information on Acesulfame-K please visit www.sunett.com.
Sucralose is a non-nutritive sweetener, manufactured from regular table sugar (sucrose). Used as a low calorie sweetener and flavor enhancer, Sucralose is made from sucrose by a patented process that makes Sucralose extremely sweet, about 600 times sweeter than sugar, and extremely stable. Sucralose is so stable that, unlike other non-nutritive sweeteners such as aspartame, it will not break down or lose its sweetness when used in cooking or baking (see our recipe section for ideas on cooking or baking with DESIGNER WHEY!). Sucralose is also not metabolized (broken down) by the body's food-digesting enzymes. This means that Sucralose has no calories! For more information on Sucralose visit www.sucralose.com.
All DESIGNER WHEY products are 98-99% lactose free and suitable for most anyone with lactose intolerances.
Glycomacropeptides (GMPs) are nature's richest source of critical muscle-building, anticatabolic BCAA's, and aid dieters in weight loss by releasing CCK, a powerful hormone that suppresses appetite (4). Also, GMPs reduce blood "stickiness," thereby lowering risk of heart attack and stroke, and improve immune function and digestion.
Protease enzymes, which hydrolyze high molecular weight proteins into peptides and amino acids, are used to partially predigest protein.
Different protease enzymes act at specific points along the different protein chains to produce tailor made and reproducible peptide blends.
Both of these statements are false. MSG is manufactured by fermentation of a carbohydrate feed stock. MSG is not found in whey, nor is it made from whey.
Bovine serum albumin (BSA) gets its name from the Latin name for whey: serum lactis. In the dictionary you will also find that serum means whey. Bovine serum albumin is a naturally occurring minor protein/peptide found in whey protein, and therefore, in cow's milk as well. Simply put, bovine serum albumin is a milk protein. If you currently drink cow's milk, you are consuming bovine serum albumin.
Bovine serum albumin is one of the protein fractions that make whey protein so beneficial for health. BSA is rich in cysteine residues that are necessary for the production of glutathione—the body's most important antioxidant (Fundamentals of Dairy Chemistry, 1988). Research shows that glutathione acts as an anti-oxidant, protecting cells against free radicals that can cause cancer and accelerate aging. Glutathione may also help to enhance your immune system.
Any extreme temperatures, freezing or high heat (above ~140ºF), can denature protein (produce cross-linking) and reduce its solubility, digestibility and bioavailability.
Blending a protein solution (heat and foaming) can result in the denaturation of proteins, leading to a loss of solubility and biological functionality. However, the small amount of heat or foaming produced during preparation of a shake from a powder by blending in a household blender will not cause any damage to the proteins.
Immediately does not mean instantly. However, drinking within 30 minutes of mixing is smart since pure protein in the liquid form is an extremely fertile environment for airborne bacteria growth. Leaving a protein drink (reconstituted from powder) in a refrigerator for two hours is probably okay, but not overnight.
DESIGNER WHEY Protein is the best protein supplement available to you. Three separate university studies have proven that DESIGNER WHEY increases lean muscle while decreasing body fat. On average, in university studies DESIGNER WHEY helped slash body fat an average of 3.7lbs and increased lean muscle mass an average of 8.6lbs when used in conjunction with a systematic workout program.
This will depend upon genetics, technique and your level of motivation and dedication. In addition to providing your body with high-quality protein like DESIGNER WHEY, you must participate in a systematic weight-training program on a regular basis. This is not to say you must work out if you use DESIGNER WHEY. DESIGNER WHEY is still a tasty and convenient protein supplement to add to your healthy diet, whether or not you exercise.
During exercise, your muscle glycogen and amino acid stores become depleted. After exercise, as a result of heightened insulin sensitivity and muscle cell receptor site stimulation, your muscles are primed to receive protein and carbohydrates.
It is important to consume DESIGNER WHEY with grape juice [or any high glycemic (sweet) carbohydrate] immediately (15 - 30 mins) after your workout. This is based on scientific research that demonstrates consuming high glycemic carbohydrates and protein simultaneously increases the rate of muscle glycogen (carbohydrate) synthesis and protein storage after exercise. (16) In other words, the post-workout carbohydrate/protein meal enhances glycogen re-synthesis and protein synthesis for faster recovery and improved muscle growth.
Yes, but please see a physician or other qualified health care practitioner first. Ask the doctor to review the ingredients and the supplement facts on the DESIGNER WHEY label.
You can still take DESIGNER WHEY, but please see a physician or other qualified health care practitioner first.
DESIGNER WHEY™ has been tested in several clinical studies and is considered by many as the most researched protein available.
DESIGNER WHEY™ has been shown to help promote muscle growth and fat loss in carefully controlled settings.
In 3 separate university studies, athletes (both men & women) who supplemented their diet with DESIGNER WHEY™ gained on average 8.6 lbs of lean muscle and lost an average of 3.7 lbs. of body fat after 4 weeks of systematic exercise training.
In one double blind study, DESIGNER WHEY was compared head to head with regular whey protein. After just 28 days, subjects taking DESIGNER WHEY gained over three times more lean mass, while doubling their fat loss compared to the regular whey group. These results make it easy to see why DESIGNER WHEY has been #1 in protein since 1993.
DESIGNER WHEY has been proven an effective treatment for renal dialysis patients. After 3 months, patients individuals using DESIGNER WHEY improved their serum albumin levels (a health marker) 9%.
In a study conducted at Case Western Reserve University, laboratory animals fed a diet of DESIGNER WHEY™ had a reduction of cancerous tumors of the head and neck by 60% when used in conjunction with photodynamic therapy. Researchers are currently evaluating whether or not Designer Whey™ may offer similar benefits to human patients with cancer of the head and neck (24).
Further, we are continuously participating in university and medical research to examine the proper levels of protein intake and possible health benefits for health conscious individuals like you.
