What is Protein Complex?

Protein Complex is a multi-phase protein supplement featuring a matrix of six different premium protein sources, including whey protein isolate, whey protein concentrate, whey protein hydrolysate, milk protein, egg protein, and micellar casein. By using both slow, medium, and fast-acting protein sources, Pure Nutrition Protein Complex nourished your body with muscle-building amino acids immediately after consumption and for up to eight hours after.
Pure Nutrition Protein Complex tastes amazing, mixes instantly, and has absolutely no aspartame or artificial food dyes. Each serving of Protein Complex provides over 4 grams of branched-chain amino acids (BCAA) and 4 grams of L-glutamine.        
If you’re looking for a protein supplement that is exclusively fast-acting or sustained-release, we recommend Whey Isolate or Pure Casein, respectively.

Why Protein Is So Important

Protein is one of the three essential macronutrients for humans; it is necessary for building muscle mass, synthesizing neurotransmitters, producing energy, modulating the immune system, and much more.2
Protein is composed of smaller molecules called amino acid, which are ultimately the building blocks of skeletal muscle. When you eat protein, your body breaks it down into small amino acid chains and single amino acids, which can then go onto perform a multitude of functions.3
Each protein source in Protein Complex is a complete protein, meaning they all contain the essential amino acids necessary for building muscle.4

Benefits of Protein Complex

It is now well-established that protein requirements tend to be higher in active individuals (particularly individuals who routinely train with weights or at high intensities).1
Scientific studies in recent years show that protein sources rich in the BCAA L-leucine stimulate muscle protein synthesis more intensely than protein sources lacking L-leucine.5 Each serving of Protein Complex matrix contains a sufficient amount of L-leucine to maximize muscle protein synthesis, resulting in optimal muscle building and recovery.

Furthermore, regular consumption of the premium protein sources in Protein Complex has many benefits beyond just building lean mass and losing body fat. See below for a comprehensive list of the research-backed benefits of Protein Complex:

  • Six different complete protein sources with over 4 grams of BCAAs per serving to maximize muscle protein synthesis6
  • Multi-phase protein matrix that releases amino acids quickly, moderately, and slowly
  • Tastes delicious and can be added to many foods for a simple protein boost
  • Enhances the anabolic response to resistance training and intense exercise7
  • Has sustained-release protein sources that inhibit muscle catabolism for up to 8 hours8
  • Supports immune system functioning, especially in those who keep physically active9

What Makes Pure Nutrition Protein Complex the Best Multi-Phase Protein Supplement on the Market?

Pure Nutrition Protein Complex is the most advanced protein matrix supplement available, featuring six premium sources of complete protein, including whey protein isolate, whey protein concentrate, whey protein hydrolysate, milk protein, egg protein, and micellar casein. This provides your body with fast-, medium-, and slow-acting protein sources that release amino acids in a multi-phase manner to keep you anabolic for hours.
Protein Complex also mixes instantly in a shaker cup, blender, or even with a spoon and liquid of your choosing. Don’t want to drink it? No problem! You can add Protein Complex to many foods, such as oatmeal or yogurt.
Contrary to many protein powders on the market, Pure Nutrition Protein Complex is made in a cGMP facility using state-of-the-art manufacturing processes to ensure only the purest proteins make it into the final product.

One scoop of Protein Complex contains:

  • Over 21 grams of complete protein from six premium sources
  • Over 4 grams of muscle-building BCAAs
  • Only 5 grams of net carbs
  • Only 1 gram of fat
  • No aspartame

Pure Nutrition Protein Complex is formulated to give your body the muscle-building nutrients it needs with none of the fluff and fillers that detract from your goals.  

Who Should Use Protein Complex

Pure Nutrition Protein Complex is a premium protein supplement with a multi-phase matrix of protein sources that will help most anyone, especially:

  • Active gym-goers and athletes
  • Individuals who want to build lean body mass and lose body fat
  • Endurance athletes and distance runners
  • Bodybuilders and physique competitors
  • Anyone who needs a simple source of protein to meet their daily needs

Frequently Asked Questions:

Q: I’m lactose intolerant, can I still use Protein Complex?
A: Pure Nutrition Protein Complex contains small amounts of lactose, but we offer protein powders with minimal lactose content - such as Pure Whey Isolate and Beef Protein.
Q: How much protein should I consume per day?
A: Research cited herein suggests that active individuals can benefit by eating around 1 gram of protein per pound of lean body mass. For example, someone who is 200 lbs and 10% body fat would want to eat around 180 grams of protein per day.
Q: When is the best time to consume Protein Complex?
A: Protein Complex is ideal for before and after physical activity, but can be used any time of the day to help you meet your protein needs.
Q: Can I mix Protein Complex in food instead of drinking it?
A: Yes! Pure Nutrition Protein Complex mixes easily in many foods, like oatmeal and yogurt, for a quick protein boost and added flavor.
