Benefits of 1UP Nutrition’s Pure Rebuild to build muscle

1UP Pure Rebuild is a fantastic tool to build hard, dense, lean muscle. This post-workout drink delivers all the nutrients your body needs to help you make the most of your work in the gym.


In-Depth Ingredient Breakdown


Each serving of Pure Rebuild contains high-quality ingredients dosed right. Nothing you don’t need and everything you do — we’re all about transparent, open products with no surprises.


5.0 grams/5000 mg of Vegan L-Glutamine 

L-Glutamine is the most common amino acid in your muscles. Therefore, using it assists in muscle building and protein synthesis. It supports lean mass gains, recovery and immune system function. 


Creatine is the single most studied ingredient in the history of dietary supplements. Creatine enhances the body's capacity to perform high intensity work (and assists greater muscle size and performance gains as a results) 

5 grams/5000 mg Creatine Monohydrate 

Creatine Monohydrate is one of the most popular supplements used by people looking to build lean muscle mass, maximize performance and increased strength. From decades of research and hundreds of studies, there are several well substantiated benefits to creatine monohydrate including: Increased muscle levels of creatine, Increased work capacity and improved training, and Greater increases in lean body mass 


2.5 grams/2500 mg Betaine Anhydrous 

Betaine anhydrous is a versatile vitamin that is used by the body for a wide variety of physical purposes. It is essential to the maintenance of intestinal function and cell production. Promotes cellular hydration (that is why it is great to take with creatine). It ramps up protein synthesis to help with muscle growth and strength gains. It may also help support kidney health, and it may also function as an antioxidant 

3.5 grams/3500 mg of EAA Complex (9 Essential Amino Acids) 

Essential amino acids cannot be made by the body. As a result, they must come from outside source. You are in the gym for 1-2 hours a day and the rest of 22 hours your muscles are recovering. The muscle recovery starts during workout, the sooner you recover, the quicker you can train the same body part. This leads to quicker and better results. 



3 BCAA - Branch Chain Amino Acids




Your body naturally breaks down protein. Slowing the rate at which this occurs aids in the maintenance of muscle mass. L-Leucine has a key role in stimulating protein synthesis and muscle growth. In other words, it helps you to keep the muscle mass you have. It also assists in muscle repair after a strenuous exercise regimen. Your muscles stay strong and are better able to recover from your training program.




To build muscle mass, your body must have the fuel it needs for the entire process. That includes the stages of repair and rebuilding. It's in these stages that L-Isoleucine is particularly important. This BCAA also helps to improve endurance. Body builders get energy-boosting benefits from this nutrient, and as a result they can keep up with their strenuous regimen and maximize performance.




Your body needs more energy during intense exercise. To provide it, L-Valine produces extra glucose. This helps to keep your body going and also stops the breakdown of muscle. This BCAA also aids in tissue repair and blood sugar regulation. In other words, it helps everything in the body work efficiently. It is necessary for the healthy function of all cells and organs.


L Lysine 

helps to build a healthy immune system. It is involved in the development of antibodies and has important antiviral properties. 


helps to maintain the balance of protein within the body and therefore supports normal growth and development. It is also involved in supporting the central nervous system, cardiovascular system, immune function, and liver function. 


Methionine, like the important Arginine, is a sulphur-containing essential amino acid. It helps the body to effectively process and remove fat. 


is converted into another amino acid called tyrosine. This amino acid is needed to form important brain chemicals (neurotransmitters and hormones) including norepinephrine (aka noradrenaline), epinephrine (aka adrenaline), their precursor L-dopa, and finally thyroid hormones, which are responsible for the regulation of our metabolism. 


essential to ensure the regulation of growth and natural development and repair mechanisms. 


is required to produce the important neurotransmitter serotonin. 

Electrolyte Complex

When you sweat, you lose more than water. You also lose critical electrolytes, like sodium and potassium, which help the brain communicate with muscles and regulate fluid level balance throughout the body. Significant losses in fluids and electrolytes can negatively impact performance, especially during long bouts of training.
