Whey Protein Concentrate (WPC) : Of a similar make-up as the Isolate version, it still has a high biological value, it does contain more of the unwanted contents of Whey such as Fat, Lactose or Cholesterol when compared to Whey Isolate (which incidentially makes it slower absorbing than WPI). Put very simply it’s still Whey Protein, which overall is regarded as the highest quality protein type for bodybuilding, at the lowest cost.
Casein Protein : A milk protein known for its unique Peptides, excellent Amino Acid profile and slow absorption. Casein like other Protein sources provides a rich Amino Acid supply to the body. Casein is pH sensitive and gels in the acidic environment of the stomach; as such it is an extremely slow digesting Protein source that slowly enters the blood stream. Its main advantage is it shall continue to feed your muscles long after Whey Proteins have dropped off. In studies 4 Casein has shown to continue working 7 hours after consumption offering a strong Anti-Catabolic effect which is not as prominent with fast digesting Proteins. It does however have only a minor impact on Protein Synthesis, which is why this protein typically may be combined with a fast acting Whey Protein or utilized as a pre sleep, time release or night time supplement.
Egg Protein : In years gone bodybuilders would consume eggs like they were going out of fashion in order to get protein in their diets. Today however it’s been made simple with Egg Protein being produced as supplements. An egg contains about 6 grams of high quality protein, so high that it is used as the standard by which other foods are measured. Eggs also are a rich source of vitamins, including A, E & K, B vitamins, Riboflavin and Folic Acid 5 . They contain all eight essential amino acids needed for muscle recovery and the building of important minerals. You shall find Egg Protein in some of the blended proteins which are available.
Soy Protein : Soy is a Protein that ranks right up there with the best in the Protein Digestibility Corrected Amino Acid Score. Soy Protein is generally very low in or free of Fat, Cholesterol, and Lactose. It is approved for those who are Lactose Intolerant, and is used as a Meat substitute. An Isolate Soy powder shall possess 90%+ Protein 4 .
Please consult your physician first (especially if you have a medical condition). Do not use if you are pregnant/lactating or under the age of 18.
