BCAAs Over Sports Drinks

Here is the problem with a lot of sports drinks on the market today. #1. They are loaded with sugar. #2. They often don't support lean muscle growth or improved endurance.


UXO's PURE BCAA was designed to help jump-start the muscle-building process during and after weight training.* BCAA's have been shown to support protein synthesis leading to more lean muscle gains.*
Drink this formula while working out to improve hydration and post-workout recovery.* We added electrolytes to this formula to help you replace important nutrients you lose through sweat. And there is 0 added sugar

Pure BCAA includes electrolytes, antioxidants, vitamin B6, and other performance-supporting ingredients with incredible flavors. With UXO you can trust you are getting the best product at reasonable prices.


They are the building blocks of protein synthesis and muscle production.* BCAAs are widely used to alleviate fatigue, improve athletic performance and stimulate muscle recovery after exercise.* A lot of studies show that having a ratio of 2:1:1 between Leucine, Isoleucine, and Valine is the optimal amount for building muscle and reducing fatigue.*

Sodium and Potassium replenish your body with essential nutrients and minerals that you lose through sweat.* This is important for optimal performance and muscle hydration, especially during high intensity workouts.


L-Glutamine is naturally produced internally, it is the most abundant amino acid found in the body.* Glutamine is needed in larger quantities for someone who is conducting intense training. Because of this, it must be supplemented through food or supplements.* Failing to supplement L-Glutamine forces your body to break down muscle to release more of this amino acid. So, if your goals are to maintain or increase lean muscle mass, you will want to supplement Glutamine with your workout regiment.* In some studies, it is shown to decrease muscle soreness and improve recovery time after intense exercise.

The Many Benefits of BCAAs

BCAAs Make up a very large portion of the body's Amino Acid Pool. This makes up around 40% of all essential amino acids present in your body and around 18% of those found in your muscles.


  • The use of BCAAs could help prevent you from falling into a catabolic state during periods of fasting, cardio, or intense training sessions.*
  • BCAAs are involved in, and can assist with regulating your blood sugar levels*
  • 2:1:1 ratio because L-Leucine has the biggest impact on your body's capacity to build muscle proteins. Isoleucine and Valine are more effective at producing energy and regulating blood sugar levels.*
  • BCAAs support decreased recovery time.*
  • BCAAs have been shown to activate specific enzymes responsible for building muscle.

As a dietary supplement, take one (1) Scoop with 8-12 fl oz of water. Sip on during workout or throughout the day.

For use by healthy adults only, not recommended for persons under the age of 18. Do not use if you are pregnant or nursing. Individuals should not consume other caffeinated products in conjunction with this product. Seek advice from a healthcare professional before taking if you have any preexisting medical condition to ensure it is safe to take this product. In case of accidental overdose, contact a poison control center immediately. Avoid alcohol and prescription stimulants while taking this product. Exceeding recommended serving will not improve results and may cause serious adverse health effects. Discontinue use and contact a licensed healthcare professional immediately if you experience an unusually rapid heartbeat, dizziness, severe headache, or shortness of breath. KEEP OUT OF THE REACH OF CHILDREN.

50 servings at 6.5g scoop of BCAAs in a 2:1:1 Ratio.



BCAAs are made up of 3 common Amino Acids: Leucine, Isoleucine, and Valine.  

They are the only amino acids not degraded in the liver. All other amino acids are regulated by the gut and the liver before being circulated elsewhere in the body. However, BCAAs head directly into the bloodstream. This means that dietary intake of BCAAs directly influences plasma levels and concentrations in muscle tissue. Interestingly, BCAAs are burned for energy (oxidized) during exercise, so they’re also an important exercise fuel.*

Because BCAAs are so important to muscle tissue, and because they help maintain blood sugar levels, it’s important to get enough to support your workouts. Consuming a carbohydrate, protein, and amino acid beverage during and after training can induce an insulin response, which helps transport BCAAs into cells. However, the availability of leucine is more important than insulin. Within the muscle cell there’s one particular regulatory pathway for protein synthesis that’s stimulated by insulin, but dependent on leucine. In other words, protein synthesis depends on how much leucine is available. And since BCAA levels decline with exercise, it makes sense to supplement with them during and/or after workouts*

WHY 2:1:1 Ratio and not higher?

Leucine is the main amino acid due to its muscle-building benefits.* This is the primary ingredient in the various ratio counts on the market, 2:1:1. 4:1:1, 8:1:1, 10:1:1, and 12:1:1. It is important to focus on how Leucine affects the body and the way it helps our muscles grow.* Leucine activates the protein known as mTOR or a Mechanistic target of rapamycin. It combines with other protein cells and begins to regulate cell growth.

Because of the importance of Leucine, many companies will stack more of it in the ratio for marketing . . . the more the better right?? You want that Leucine to instigate the protein synthesis process to put on more muscle . . .

Well, sometimes more isn’t always better.A study was done where subjects were given Leucine, 2:1:1 BCAAs, and a placebo. The Results found that BCAAs increased protein synthesis even more so than Leucine alone. The study gave credit that BCAAs help to lessen fatigue and fuel muscles.*  

People often see the higher number and figure 10:1:1 is five times better than 2:1:1 ratio . . . Here is the issue . . . There isn't much research supporting that the higher dosages will deliver any better results than a 2:1:1 ratio. So while you are paying more for a higher dosage, you may be flushing your money down the toilet. There are consistent studies and mentions of the 2:1:1 ratio for more than 20 years. If you are serious about fitness . . . stick with the tried and true, with plenty of research to support it.*


Recommended to drink on while working out. This way you will get full hydration benefits of the electrolytes. BCAAs can also assist with muscle endurance during even the most intense workouts.* Taking in the additional Glutamine will also help replenish Glutamine levels leading to more lean muscle growth and more efficient recovery, post-workout.*
