I get it all the time- "What are you taking", "Whats that in your bottle?", "Well I saw this protein on sale, what do you think about it?", "Isn't all protein just the same, and why should I take that other stuff??" I will go through all the different types of protein, how they are made, the pros and cons, and when to take them. Its time to clear that protein confusion up!

The health/sports supplement industry is one of the largest selling industries in todays society. There are TONS of companies selling THOUSANDS of products promising to do the same thing-to get you results. Now, dont get me wrong, I can guarentee you right now that you will get results with ANY supplement you take. The REAL question is if you will get the results that YOU want. All protein is not created equal.


- Whey Concentrate: Derived from the cheese-making process. In this process, the liquid separated from the cheese contains the whey protein, lactose, and minerals. There are filtering steps that take out some lactose and other impurities. It is here where you will get your Whey Concentrate Powder. A powder that must be at least 25% Protein—actual contents vary. It can contain from 25%-80% whey protein, up to 55% lactose, and 1%-7% Fat.
*CON: Unknown amounts of actual whey, not recommended to those who are lactose- intolerant.

-Whey Isolate: Made through the same process as concentrate, but has been taking through a longer filtration process. Whey Isolate powder must be at least
90% protein. This contains 90+% of whey protein, negligible amounts of lactose,and less than 1% fat.
*PRO: More pure source of protein, also the most
*CON: More expensive

-Hydrolyzed Whey: When whey protein is hydrolyzed the
protein chains are broken down into smaller segments. It is used highly in infant formulas and for medical use, due to is hypoallergenic nature.
*CON: More expensive.
*PRO: Pure, Hypoallerginic, high-quality protein, &
super fast absorption.

-Soy Protein: Derived from the soybean from the defatted soybean meal.
*PRO: Contains all the essential amino acids. Good
alternative for those who cannot digest whey
*CON: Boosts estrogen levels

-Egg Protein: Derived from eggs :)
*PRO: Good for those unable to digest whey, or
*CON: Less protein content than a whole egg (so
you're better off hard-boiling the egg).
Virtually free of carbs and fat, and low in

-Casein Protein: The predominant protein found in milk, making up 80% of the protein and whey being the remaining 20%. There are three types of Casein protein: Calcium Caseinate, Micellar Casein, and milk protein. Calcium Caseinate is the lowest quality and is usually used in food products. Micellar Casein is 100% pure casein protein and milk protein contains both micellar casein and whey.
*PRO: Digestion takes up to 7 hours.
*CON: Not ideal for pre/post workout meals.


-Whey Concentrate: Relatively fast absorption
(Depending on the whey content).
Ideal upon waking, before and after
a workout.

-Whey Isolate:: Fast absorption. Ideal upon waking,
before, and after a workout.

-Hydrolyzed Whey: Fastest absorption. Ideal before and
after workouts.

-Soy Protein: Moderate absorption. Ideal in between
meals, and before workouts.

-Egg Protein: Fast absorption. Ideal whenever you would
eat eggs, and prior to and after your

-Casein Protein: Slow-digesting protein. Ideal before
bed or whenever you are unable to eat
within 2-3 hours.

I hope this cleared up any confusion you had about proteins your are taking, or any protein you were thinking about adding to your supplement cabinet. I also put a link to a website that has 101 protein shake recipes using all different types of protein. Enjoy!!

Coming soon: Supplement 411, where I will discuss the other popular supplements being taken and how/when to take them. Aloha ladies!!!
