Why Concentrate vs. Isolate Matters More Than You Think

Whey proteins are found in milk. Manufacturers separate the whey, then dry it to make supplements. People mostly use whey supplements to support muscle gain, recovery, daily protein intake, and weight management.ย 

Whey isolate has more protein per gram. It also has less lactose, fewer calories, and less fat compared to whey concentrate.

Milk has two main proteins: whey and casein. These proteins separate during cheese making. Casein makes the curd, and the leftover liquid contains whey proteins, lactose, minerals, and small amounts of fats. Manufacturers dry the liquid to make whey protein supplements.1

Whey protein concentrate has about 35-80% protein. Manufacturers change protein concentrations based on the purpose of the protein powder.2

Eighty-percent whey protein concentrate has about 4โ€“8% fat and 4โ€“10% lactose.3 It also contains minerals like calcium, magnesium, zinc, potassium, and sodium.2

Lower-protein whey concentrates are used in processed foods and baking to improve flavor, texture, and shelf life.4

Higher-protein whey concentrate (80% or more protein) is mainly for people who want to build and maintain muscle and improve fitness.4

How does this taste? I find most pre-workouts are way too sweet these days.

I prefer getting my nutrients from whole foods, but this is a great backup.

Would this be too much caffeine for someone who is sensitive to stimulants?
