Ideal Muscle Support for Every
Level of Physique and Performance


Research over the past decade clearly shows that protein supplements are vital for anyone aiming to maximize muscularity and athletic performance. After all, protein makes up about 80% of the dry-weight of skeletal muscle, and muscle cells need an abundant and constant supply of amino acids to support muscle repair and growth.

The benefits of protein supplementation in bodybuilders have been known since the late 19th century, when Eugen Sandow was ingesting whole raw eggs to turbo-charge his diet. Today, over a century later, there is a mass of scientific evidence available supporting the anabolic properties of protein, especially when combined with heavy weight training. All in all, protein is the single most important macronutrient for the growth and maintenance of tissues in the body.

It has been reported that after a single bout of heavy arm training, protein synthesis rate increases by about 50% in the first four hours and doubles around the 24-hour mark. Such findings are supported by many other studies illustrating the profound effect of weight training on anabolism. However, it has also been shown that muscle breakdown (catabolism) increases during this period and is exacerbated under conditions of caloric deficit (i.e., dieting). As such, optimal protein requirements for weight-training athletes (especially bodybuilders and CrossFitters) are at least twice that of the average sedentary Joe. Based on this, it should make sense when fitness gurus tell you that the success of any strength-training program relies as much on diet as it does on getting into the gym.

Although the importance of a high-protein diet has been known for so long, it wasn’t until the 1950s that protein supplements were mass-marketed. These products were generally a formula of soybean flour and flavoring, which had low bioavailabilty/biological value and tasted horrible. Back then, the general consensus was that it had to taste bad to be effective. Fortunately, supplement science has come a long way since the days of Eugen Sandow and our ideology has evolved. We now have highly effective products, tailored to the needs of the individual, that also taste great. When it comes to tailoring great tasting and high-grade protein supplements, ProSource stands out among its competition in quality and price. In the remainder of this article, we will focus on three key protein supplements aimed at satisfying the needs of highly active people at all levels of fitness.

1. High-Performance Athlete (NytroWhey Ultra Elite)

In top-level athletics (like competitive bodybuilding), the difference between a win and a loss can be miniscule. As such, high-performance athletes have refined needs when it comes to gaining an edge on the competition. It is imperative that every calorie ingested is of the highest purity, and ProSource's NytroWhey® Ultra Elite was formulated specifically for this task.

When combined with heavy resistance training, whey protein isolate (WPI) and whey protein hydrolysate (WPH) hold the top scientific honors for anabolic response, increased protein synthesis, and muscle recovery response. Based on scientific rigor and the needs of top athletes worldwide, NytroWhey Ultra Elite provides a unique top-shelf protein blend of WPI and WPH combined with other factors that promote protein absorption, bioavailabilty, and increased anabolism.

A few key features about NytroWhey Ultra Elite:

  • NytroWhey® Ultra Elite is very low in carbohydrates, high in fiber, and contains the highest grade of WPI and WPH produced in the USA.
  • WPH is the fastest absorbed protein product available, resulting in the greatest increase in circulating amino acids over a two-hour window compared to other protein sources. This feature allows you to immediately take advantage of the post-exercise anabolic environment and truly maximize muscle growth.
  • Post-workout protein hydrolysate ingestion increases highly anabolic insulin. Insulin secretion is vitally important to maximizing the transport of amino acids to muscle tissue.
  • Whey protein hydrolysate is “predigested,” thus it is well tolerated after training. As a result, there’s less bloating due to rapid absorption.

As an added bonus, the ratio of WPI to WPH is carefully calibrated to take advantage of the different amino acid absorption kinetics of fast-acting WPH and moderate-digesting WPI. Hence, NytroWhey Ultra Elite provides virtually instantaneous hyperaminoacidemia upon ingestion, while maintaining blood amino acid levels for hours.

NytroWhey Ultra Elite also contains an advanced leucine peptide technology. Leucine, one of three branched chain amino acids (BCAA’s), is primarily involved in turning on anabolism when ingested. NytroWhey Ultra Elite’s proprietary form of leucine has been scientifically shown to be ultra-soluble in water, making it mix easier and digest with higher bioavailabilty than typical free-form L-leucine. With these leucine peptides added to NytroWhey Ultra Elite, this end-product boasts up to 4x the leucine (and at higher bioavailabilty) than other whey protein products on the market.

NytroWhey Ultra Elite’s unique formulation makes it an ideal protein supplement for serious/competitive high-performance athletes aiming to maximize pre-workout, intra-workout, and post-workout anabolism.

2. Peak Fitness (Original NytroWhey)

Fitness conscious athletes understand the importance of protein supplementation and getting a superior value, without sacrificing quality and nutrition. Although many people in this category do not engage in competitive sports, all individuals can benefit from a product that promotes fat loss and maintains muscle mass. Certainly, a highly active lifestyle calls for increased protein intake, so choosing the ideal supplement is important. If this sounds like you, then ProSource's Original NytroWhey® formula should be your go-to supplementation!

Original NytroWhey® formula from ProSource is formulated with a 100% WPI backbone. However, unlike some inferior products, the whey protein isolate in NytroWhey is produced from high-grade whey protein concentrate using high performance ultra microfiltration, resulting in one of the purest and most bioavailable WPI products on the market. Ultra microfiltration purifies whey protein under conditions of low temperature, low pressure and normal pH, rendering a lactose-free, pure product that retains all of its native proteins, peptides and subfractions. This novel cold-filter processing even retains sensitive protein fractions like alpha-lactalbumin and lactoferrin, which support increased immunity and health, defend against microorganisms, and aid in recovery.

A few key features about the WPI in NytroWhey Original formula:

  • The ultra microfiltered whey protein isolate in NytroWhey is undenatured and retains its natural subfractions that support anabolic responses and promote an array of health benefits.
  • Consuming NytroWhey promotes a rapid and substantial rise in blood amino acids.
  • Taken immediately pre- and post-workout, WPI promotes gains in lean mass and strength, and reductions in fat mass.

3. Round-The-Clock Muscle Maintenance (Precision Whey Protein)

In the quest for strength, muscularity, and performance, the significance of high quality whey protein supplementation cannot be overstated, especially for those who are just getting into bodybuilding and strength-based athletics.

Whey protein has been subjected to scientific investigation since its widespread utilization by consumers began in the 1990s, establishing its standing as the ideal protein supplement for athletes of all levels. Unfortunately, the excitement surrounding whey’s muscle building, fat loss, and health promoting benefits has led to issues with supply and demand. As such, in the past several years, whey prices have climbed and (in an effort to secure profit margins) the industry has been fraught with unscrupulous labeling and fraudulent protein spiking.

Based on these issues, finding a high quality product that is also a supreme nutritional value has become a daunting task.

Fortunately, the team at ProSource has a well-earned reputation for the highest manufacturing standards and 100% honest labeling. This legacy is now reflected in the launch of its newest product, Precision Whey Protein. In fact, Precision Whey Protein was developed specifically to fill this huge gap in the market: a high-quality, high-value whey protein to suit active people of all types for round-the-clock muscle maintenance.

Precision Whey Protein is 100% ultra-filtrated whey protein that is low in sugar and saturated fat, and contains no fillers or unproven blends found in many of today’s competing products. Its superior biological value makes Precision Whey Protein an ideal protein source that can be used anytime of the day to keep your anabolic drive high and promote fat loss, regardless of your fitness level.

A few key features about Precision Whey Protein:

  • Precision Whey Protein has a robust amino acid profile with 8 essential amino acids and a large amount of BCAA’s to keep catabolism down and anabolism up.
  • Its gentle processing retains more of its native protein structure, which promotes immunity and overall health.
  • Compared to other protein sources, Precision Whey has a medium absorption rate, which works well as a pre-workout protein supplement.
  • Precision Whey Protein is a great product to be taken between meals to increase protein intake (for muscle growth and recovery) and provide appetite suppression (for fat loss).

Conclusion

There is nothing more frustrating than seeing a serious and driven athlete undermining his or her training efforts with a subpar nutritional program. And yet, so many people do exactly that! It is important to remember that the recommended protein intake for a training individual ranges from one to 1.5 grams of protein daily per kilogram of bodyweight. Do the math and you’ll see that’s a lot of protein!

By all means, derive a substantial portion of this intake from whole-foods sources. But to achieve your performance and physique goals, you also need to supplement with a high-biological-value protein formula before workouts, after workouts, before you go to sleep, and elsewhere in your day as needed. Use one of the formulas referenced above, and your dietary needs will be covered in the most satisfactory manner.
