If you’ve made the decision to begin a muscle building or fat burning program, then you’re already familiar with whey protein by now.

It’s a staple bodybuilding and fitness supplement, and for many very good reasons.

Here are 5 key whey protein powder benefits you should be aware of…

5 Whey Protein Powder Benefits

Benefit #1: Concentrated Source Of L-Leucine

All proteins are made up of individual building blocks known as “amino acids”.

There are about 20 amino acids found in the human body, with 8 being considered “essential” since the body cannot produce them on its own.

The most valuable amino acid for those following an intense workout program is l-leucine. L-leucine is one of the 3 “branched-chain amino acids” (l-valine and l-isoleucine are the other two) and is the primary trigger involved in stimulating muscle growth and repair.

Consuming a sufficient amount of l-leucine each day is a critical component of your muscle building and fat burning diet, and most high quality whey proteins will deliver about 2-3 grams in every scoop.

Most people aren’t even aware of the valuable effects of l-leucine, but this is one of the most important whey protein powder benefits there is.

Benefit #2: Maximum Bio-Availability

All protein sources are ranked on the “biological value scale”, which determines how much of the total protein content is actually broken down and absorbed by the body.

Whey protein is ranked #1 on this scale, making it the most absorbable protein found in nature.

Your body will fully utilize nearly 100% of the overall protein content, whereas most other popular high protein “fitness foods” (such as chicken, fish, beef etc.) may range from as low as 65% up to around 90%.

Benefit #3: Direct Fat Burning Benefits

Whey protein is typically recommended as an effective muscle builder, but actually has a few direct fat burning effects as well.

First off, it helps to regulate cravings by decreasing the secretion of grehlin (a hormone that stimulates appetite) and increasing the secretion of CCK (a hormone that suppresses appetite).

Secondly, it increases the rate of beta oxidation (fat burning) that occurs during weight training and cardio workouts.

Thirdly, it helps to regulate your mood and energy levels during periods of calorie restriction by increasing the production of serotonin.

Benefit #4: Boosts Glutathione Levels

Whey is not only effective at helping you build muscle and burn fat at a faster rate, but also has many valuable health boosting properties as well.

This is primarily due to its ability to naturally increase the output of glutathione, which is the most powerful antioxidant in the human body.

Increased levels of glutathione will enhance the strength of your immune system, improve brain function and protect your cardiovascular system.

Benefit #5: Most Convenient Source Of Protein

In addition to all of its awesome fitness boosting and health enhancing properties, whey is also the most convenient source of protein out there.

Whey is a natural component of dairy that is isolated into powdered form, and can then be used to make an endless list of different high protein smoothies and food recipes.

A serving of whey protein can be mixed up and consumed in just a minute or two and tastes awesome when prepared properly.

For those on a structured fitness diet with higher protein intakes, whey protein is a life saver as it will make your overall meal plan far easier to follow over the long run.
