Product Details

What is Whey Protein Concentrate?

Whey is the liquid by-product that forms during cheese production. It is one of two proteins derived from cow’s milk and accounts for 20% of the total milk proteins, with casein protein making up the other 80%. Whey protein is the faster digesting of the two and delivers branched-chain amino acids (BCAAs) like l-leucine, l-isoleucine, and l-valine rapidly for faster muscle repair and recovery after workouts.

PureBulk carries two forms of whey protein: whey protein concentrate and whey protein isolate. PureBulk also carries casein protein powder. Whey protein concentrate is a cold, micro-filtered powder produced in the USA.

Whey Protein Concentrate vs. Isolate

The concentrated and isolated forms of whey protein are both complete proteins that deliver all nine essential amino acids. They have slightly different nutrition profiles due to their manufacturing processes. Isolate tends to be the more expensive form, as it takes longer to produce than concentrate. It also yields a bit more protein by weight and has fewer carbs, fat, and lactose. Both provide an impressive amount of protein, but isolate may be the better option for individuals with lactose sensitivities. See the table below for a complete breakdown of whey protein isolate vs. concentrate’s nutrition profile per 30g serving (6 tablespoons or 3 scoops).

Estimated Lactose Up to 3.5g Up to 3.5g

Whey Protein vs. Casein

Casein is another complete protein rich in BCAAs and other essential amino acids. It digests slower than whey protein and helps individuals feel full for longer. Casein is the better protein option for periods of fasting or before bed.

Potential Whey Protein Benefits

Whey Protein for Muscle Growth and Recovery

Whey protein is a common component of pre-workout nutrition for its ability to enhance muscle growth and athleticism. Whey protein concentrate powder provides the proteins the body needs to build lean muscle. It’s also rich in the branched-chain amino acid leucine, which stimulates muscle growth. Whey protein works best when paired with a strength training routine, as they synergize for better muscle protein synthesis.

The other BCAAs in whey protein help reduce muscle soreness after intense exercise, which promotes faster recovery. Rapid muscle repair allows individuals to recover and resume their workout routines faster and can reap significant lean muscle gains. Whey protein can also diminish the intensity of delayed onset muscle soreness from intense workouts when taken half an hour before exercising.

Whey Protein for Lean Muscle Preservation

In addition to stimulating muscle growth, leucine also helps preserve existing lean muscle. It’s impossible to pick what the body will burn during weight loss. Much of it is fat, but it may also catabolize muscle. Taking whey protein helps preserve lean muscle while losing weight. Muscle mass also naturally declines with age due to less physical activity and eating high-carbohydrate and low-protein meals. These factors reduce protein synthesis, and the elderly may notice a loss of muscle tone and strength or an increase in body fat over time. Remaining physically active and consuming adequate protein can mitigate age-related muscle loss.

Whey Protein for Weight Loss

Protein is the most filling of the three macronutrients. It promotes feelings of fullness with less food compared to fats and carbohydrates. Protein also reduces ghrelin, a hormone that stimulates hunger. Research shows that increasing total protein intake from 15% to 30% helped overweight women eat 441 fewer calories per day. Most notably, the participants weren’t intentionally restricting their diet.

Vegan and Vegetarian Protein Sources

PureBulk offers several vegan- and vegetarian-friendly protein powders. These may also be a better option for individuals with a milk allergy or lactose intolerance. These include:

*Vegan and vegetarian proteins are incomplete, as they don’t provide all nine essential amino acids. As a result, vegans and vegetarians mix their protein sources to ensure adequate nutrition.

Chlorella is a notable exception, as it is a vegan- and vegetarian-friendly complete protein. Spirulina, while technically a complete protein, doesn’t provide enough lysine.

How Much Protein Do I Need?

An individual’s weight and exercise habits significantly influence how much protein they need each day. The general rule is to consume at least 0.36 grams of protein per pound of body weight (0.8g/kg). However, individuals who work out regularly need two to three times more protein to facilitate muscle repair, exercise recovery, and lean muscle growth. For example, a 150-pound person following an exercise program needs 109-164 grams of protein per day. Failing to meet the body’s protein needs inhibits its ability to recover, leading to a greater risk of injuries. However, many individuals struggle to consume that much protein from meals and take whey protein powder to meet their nutritional needs.

Potential Whey Protein Side Effects

Whey protein does not typically cause side effects when taken at the suggested dose. Overconsuming whey protein may cause nausea, headache, stomachache, cramps, or fatigue. Individuals with lactose sensitivities or intolerances may experience similar side effects of consuming other dairy products. These include belching, bloating, gas, cramps, and diarrhea. Individuals with milk allergies should not take whey protein concentrate powder. Individuals with kidney disorders should not consume a high-protein diet.

Why is Sunflower Lecithin in PureBulk’s Whey Protein Concentrate Powder?

We spray dry our whey protein concentrate with a small amount of soy lecithin to prevent clumping and to increase dispersibility.

Whey Protein Concentrate Purity and Concentration

PureBulk’s whey protein concentrate contains at least 80% pure whey protein by weight and is a good source of BCAAs. It is free of sugar, taste additives, preservatives, and fillers. It arrives in a tight, vacuum-sealed bag. PureBulk’s whey protein powder tastes excellent, and individuals may add sweeteners if desired.
