Whey Protein
Concentrate (WPC): Contain 75 to 80% protein
and are less expensive than Isolates. Whey Concentrates are excellent values while
still providing a high level of protein and only a few grams of carbs and fats.
Whey Protein Isolate (WPI):
Isolates supply the highest percentage of protein (typically 90% or greater) and
are filtered to remove nearly all carbs and fats.
Whey Blends:
Blended with other proteins like casein, egg, and possibly soy to create a "time
release" or "sustained release" matrix. This is ideal as whey proteins absorb
rapidly and the other proteins absorb more slowly.
Soy
& Egg Proteins: Soy and egg proteins have been
used by athletes for years. While whey is the most popular choice, these proteins
are suitable in any program.
