Whey Protein Questions
Whey is the liquid component of cows’ milk, which is separated from the solid component, curd, during the cheese-making process. Natural whey contains water, protein, fat, minerals and lactose.
Whey products are produced when the protein elements are separated through special filtering processes or by ion exchange. This process removes the lactose and fat and leaves a highly concentrated protein that is dried into a highly functional protein powder. The ion exchange process isolates the protein from the lactose and fat due to its electrical charge.
The two main types of whey protein on the market are whey protein concentrate and whey protein isolate. Whey concentrate ranges from 19-89% protein, typically 80% in nutritional foods, 34% in infant formula, and whey isolate contains at least 90% protein. Whey protein is the highest quality product. It's a complete protein, which means it contains all nine essential amino acids, the building blocks of healthy muscles, skin, nails and other body tissues.
Whey protein is the most studied protein on the market and for good reason. It’s one of the highest quality proteins available and easily digested, making it the gold standard for protein. All of the examples below are based on scientific research:
- As we age, we begin to lose muscle. Slowing muscle loss is a great preventative strategy to help keep us mobile and injury free. Including whey protein in your diet daily along with strength training can help maintain muscle mass and muscle growth.
- Studies have attributed dairy foods to potentially lowering blood pressure, via ACE-inhibitors, which are bioactive peptides found in whey protein.
- High doses of whey protein have been shown to reduce blood levels of C-reactive protein (CRP), which is an indication that it may help with chronic inflammation.
- Whey protein is a satiating protein and those who consume whey protein over other proteins ate fewer calories and tended to lose more weight.
- Whey protein is a superstar when incorporated into a weight loss strategy or program. It’s the trifecta for weight management because it suppresses appetite which influences a lower caloric intake, boosts metabolism and helps maintain muscle mass during calorie restriction.
- Whey protein contains the amino acid cysteine, which is key in the synthesis of glutathione. Glutathione is the body's most powerful antioxidant and whey protein may boost the body’s natural antioxidant defenses through cysteine/glutathione synthesis. This means strengthened immunity.
Designer Whey products are processed using the most advanced technology available. They contain both whey protein concentrate and whey protein isolate to ensure that you benefit from the widest spectrum of whey peptides.
Scientists have various methods of measuring protein quality. Biological Value (BV) is a measure of a particular protein’s effect on nitrogen balance. The protein digestibility corrected amino acid score (PDCAAS) is a measure of how well a particular protein supplies the nine essential amino acids. Whey protein PDCAAS is 1.14, as compared to 0.94 for beef protein, and its BV is 104, compared to 100 for eggs.
In addition, whey protein empties from the stomach and is absorbed into the bloodstream from the intestine faster than any other protein sources. Due to whey’s quick digestion it has been called the “fast protein” and is the preferred protein to flood the body with amino acids so muscles can recover quicker.
Moreover, whey protein contains especially high concentrations of the branched chain amino acids (BCAAs) that are metabolized at high rates during exercise, most notably valine, isoleucine, and leucine.
While both are natural dairy products, milk contains roughly 3.3% protein that is comprised of 80% casein protein and 20% whey.
Both are high quality and complete proteins, however, whey is a quickly digestible and assimilated protein- meaning the body uses it quickly. Casein, also of high quality, is digested slowly which keeps a nice continuous flow of amino acids in the blood stream.
Whey is best really anytime, but really excels over casein on its speed of delivery. Casein's advantage over whey is the slow digestion rate makes it great right before bed time.
When it comes to children or breastfeeding mothers, protein level requirements are different for all ages and individual health history needs to be taken into consideration. We always recommend consulting with your doctor as they know you and your children better than we do.
Designer Whey is 93% lactose free. If you have any concerns regarding lactose, please contact your healthcare provider before using the product.
Designer Whey is gluten-free.
Yes, it contains very few carbohydrates so keeping track of your keto macros is easy.
As Designer Whey does contain stevia leaf extract, it is not recommended for Whole30 participants.
Designer Whey products contain a maximum of 3 grams of sugar per serving. It is sweetened with stevia leaf extract and monk fruit.
Yes, all of our milk is pasteurized at the minimum heat and time to keep the sensitive proteins intact.
Our lecithin is derived from sunflower seeds.
Whey products are predominately animal-sourced, they contain a small quantity of naturally occurring dietary cholesterol. Cholesterol is a fatty substance and is necessary for the synthesis of sex hormones, bile acids and vitamin D. It also forms the structure of every cell in your body.
Biological Value (BV) is a measure of nitrogen (protein) retained for growth and/or tissue maintenance. The BV of common food protein is based upon a study, which demonstrates that whey protein had the highest biological value of all food-grade proteins at 104. For comparison, consider the BV of these other food proteins: soy (74), casein (77) and egg (100).
The glycemic index refers to how a food, usually a carbohydrate, affects your body’s blood sugar (glucose). Proteins and fats, by nature, have little effect on blood sugar response. Research shows that protein-only meals have either a little to no effect on blood glucose.
Based on existing research, Designer Whey falls between 10 - 30 on the glycemic index. The precise glucose response will vary from person to person depending upon a myriad of factors like body composition, fitness level, as well as diet.
Native whey protein is believed to be the cleanest, least processed whey protein available.
It is micro/ultra-filtrated at a low temperature directly from milk. It maintains protein bioavailability because the whey is exposed to minimal heat (denaturation of protein occurs at high heat).
Native whey’s milk source is never exposed to acid or cheese rennet and therefore has unique functional and compositional properties compared to regular cheese whey. It contains an inherently high concentration of the branched chain amino acid (BCAA), leucine, a trigger for protein synthesis, making it one of the most important amino acids to human physiology and performance.
It is also higher in the amino acids: tryptophan and cysteine. Cysteine is a precursor to one of the most abundant and naturally occurring anti-oxidants in the body - glutathione.
It's made from premium quality milk – non-GMO, grass fed, free of artificial growth hormones and artificial antibiotics – from farms using the best farming practices.
The skim milk is cold-filtered and avoids the cheese making process that regular whey is exposed to. Minimal heat and minimal processing means minimal denaturation. That translates into a more bioavailable whey protein for utilization by the body.
Designer Whey Native Whey contains no artificial flavors, sweeteners, colors or preservatives. It has no added sugar, no fillers and is certified gluten free and kosher.
Native whey protein is believed to be the cleanest, least processed whey protein available. It is micro/ultra-filtrated -serving a higher BCAA count than traditional isolates on the market, including whey isolate and milk protein isolates.
Designer Whey Native Whey Isolate is a clinically tested and proven whey protein isolate with outstanding results in muscle output (power activation and endurance), and recovery (muscle power recovery and reduced fatigue).
It has been tested in multiple clinical studies conducted by sports nutrition centers of excellence. The clinical studies measured the performance of our protein in head-to-head tests against other proteins including conventional whey protein isolate, milk protein isolate, micellar casein and placebo. Results have been published in scientific reviews.
Every serving contains 32g of clinically proven native whey isolate protein, with additional free-form branched chain amino acids (BCAAs), and the leucine transporter, glutamine.
The result is a unique powerhouse muscle mass activator with 36g of protein nitrogen, 9.6g of BCAAs, 5.5g of leucine and 18.1g of essential amino acids. The BCAA ratio of 2.6:1:1 (leucine to isoleucine and valine) is key to optimal performance, strength, recovery, muscle gains and the maintenance of a lean body.
