Introduction To Protein


Build Your Pillar Of Power

Whether you're new to working out or are a seasoned pro, a quality protein powder is a necessity! Simply put, protein is the single most important thing you must consume daily to build new muscle tissue. Muscle wouldn't exist without it!

While you can get your protein from food sources - and it's recommended that you do - protein powder is a great addition to ensure you get enough on a daily basis. Not to mention protein supplements are convenient and fast absorbing for before and after your workouts, so you can really take your results to the next level.

Protein shakes also act as the perfect solution for when you get busy and need to get your protein in right away.


There's A Protein For Everyone

If you want to improve your health and fitness – protein can help!* Protein provides the body with the building blocks to produce amino acids that are used for building muscle. While both carbohydrates and fats can vary from diet to diet, protein is one nutrient that should remain constant. The benefits are vast! Protein may help promote:

  • Muscle growth*
  • Enhanced recovery *
  • Optimal immune response*
  • A normal
  • healthy appetite*

Pack Your Gym Bag With Protein

Getting the right protein is important, and there are a number of different types that you'll need to choose from to accomplish your goals.

Whey protein powder is a top quality and fast acting protein that's perfect immediately after your workout for optimal absorption.*

Casein protein powder is a slowly digesting protein which can help provide a steady stream of amino acids to the muscles for longer durations.* Casein is perfect to take right before bed, for all night recovery.*

Egg and Soy protein powders are a fantastic option for anyone who's a vegetarian or who is lactose intolerant – if either of those are a concern for you it's definitely something you'll want to consider.

Picking Your Protein

Once you know what type of protein you want to use, the next step is to identify the nutritional values within that specific protein.

First, you should always check the calories per serving. Both weight loss and muscle gains boil down to your calorie intake, so you'll want to be sure the protein you choose aligns with your goals. Generally protein powders are divided into lean, meal replacement and weight gainers.

Next, make sure the grams of protein per serving are adequate for your goal. A good general rule of thumb is to consume 1 gram of protein for every pound of body weight. Be sure to consume your daily allotment in small amounts throughout the day to prevent overconsumption and to maximize your results.

Don't Settle For the Wrong Protein

Another important thing to look at when picking your protein supplement is the carbohydrate and fat content. In addition to calories and protein, these should also be accounted for in your daily nutrition plan.

Finally, consider taste. Since you should definitely enjoy the healthy foods you eat, make sure to choose a flavor that you think will appeal to your taste buds. Read our customer reviews if you're still unsure.

By taking all of these into consideration, you should have no problem picking out the perfect product.

Discover A Powerful Physique

Once you've selected your protein powder, you'll want to make sure you're doing everything right to get the most out of it. To recap, ideally you should be consuming a fast acting protein (whey) immediately before and after your workout, as well as a supplement in between meals. To keep your energy levels up, combine this protein with a good source of complex carbohydrates.

Then throughout the rest of the day continue consuming your food and protein supplements at regular intervals. Lastly, take a slow digesting protein (casein) right before you go to bed.

If you follow this simple guideline, your muscles will have everything they need to recovery from your workouts and you'll get the results you're looking for!
