: How does whey protein compare to soy protein?
: Here are some of the differences between whey protein and soy protein.
- Whey protein is a nutritionally complete protein. It contains
bioactive ingredients, like immunoglobulins and lactoferrin, that help
support the immune system.
- Athletes prefer whey protein to soy protein due to its rich
abundance of branched chain amino acids and its quick absorption rate.
These are important to help repair and rebuild muscles after a workout
or competitive event.
- Whey protein has a fresh, neutral taste compared and will not change the taste of foods you add it to.
- Whey protein does not contain isoflavones or any other components with potential hormonal effects.
: I eat a lot of fish, chicken, eggs, soy and beef. Why do I still need whey protein?
: Healthy diets should regularly include high quality, low fat
sources of protein, like whey protein. Calories do count and you want to
make sure that you are getting the most benefit from the calories you
consume. Compared to other proteins, on a gram-to-gram basis whey
protein isolate delivers more essential amino acids to the body but
without the fat or cholesterol. Nutrition experts recommend a diet with a
variety of protein foods but for optimal results make sure that one of
them is whey protein.
: Can I get enough whey protein by drinking milk?
: Milk is a highly nutritious beverage however, it only contains
about 1% of whey protein. In order to get all the benefits of whey
protein, you need to take a concentrated whey protein powder.

- Added Ingredients
: What individual components are found in whey protein?
: Whey protein is a combination of a number of individual
protein components. In recent years new technology has allowed
manufacturers to isolate and further purify many of these for use in new
and exciting nutrition and oral care products.

Lactoferrin Lactoferrin Immunoglobulins Immunoglobulins
Lactoperoxidase Lactoperoxidase Bovine Serum Albumin Bovine Serum

: Is whey protein easy to digest?
: Whey protein is a soluble, very easy to digest protein. It
quickly enters the body to provide the important essential amino acids
needed to nourish muscles and other body tissues. This is one of the
reasons it is a common ingredient in infant formula and protein
supplements for medical use.
: What is hydrolyzed whey protein?
: When whey protein is hydrolyzed the protein chains are broken
down into smaller segments called "peptides". Hydrolyzed whey protein is
still a high quality protein however, it is less likely to cause an
allergic reaction than non-hydrolyzed whey protein. It is most commonly
used in infant formulas and specialty protein supplements for medical
: If I'm lactose intolerant should I avoid whey protein?
: Individuals with lactose intolerance should select a pure whey
protein isolate, which has less than 0.1 gram of lactose per tablespoon
(20 grams). This is less lactose than the amount found in a cup of
yogurt and research has shown that most people with lactose intolerance
have no trouble taking this very small amount of lactose. Individuals
with lactose intolerance should avoid whey protein concentrates as they
usually contain lactose.
: Is whey protein a good choice for vegetarians?
: Yes, whey protein is an excellent choice for vegetarians who include dairy products in their diet.

: Is whey protein safe for pregnant women and children?
: Whey protein is a complete high quality protein and should be
an acceptable protein source for healthy pregnant women and children,
provided they are not allergic to dairy proteins. The second most
abundant component in whey protein is alpha-lactalbumin, which is one of
the main whey proteins in human breast milk. Infant formulas often
contain whey protein, including special formulas for premature infants.
Prior to taking whey protein, both pregnant women and parents of young
children should consult a physician to be sure whey protein is right for
