Description
XR Series™ BCAA Advance XR™
  • Advanced BCAA System to Spare Muscle Breakdown & Preserve Glycogen*
  • Immediate & Sustained 6 Hour Extended Release Anabolic Leucine
  • OT2™ Technology for Advanced Muscle Protein Synthesis*
THE BENEFITS OF BCAA Advance XR™
GNC’s superior Pro Performance® XR Series™ BCAA Advance XR™ is uniquely formulated to help athletes receive immediate release of muscle fueling Branched Chain Amino Acids (BCAA), plus a longer lasting supply of anabolic Leucine. Leucine is the key BCAA shown to impact muscle protein synthesis.* This anabolic bulking block is now Optimal Timing Technology - OT2™ - enhanced to provide a sustained release of Leucine for six hours.

OT2™ - THE EXCLUSIVE GNC ADVANTAGE
OT2™ is GNC’s intelligent nutrient delivery system engineered to help release key ingredients during crucial times when you need them most! These breakthrough products are designed to deliver immediate and sustained release of ingredients to help maintain benefits throughout your workout, day or night. OT2™ ingredients are coated with a special technology that controls when they are released.

These special actives may be seen in the product- now that’s a real technology you can see and feel! It goes without stating that protein is critical for stimulating muscle synthesis and preserving muscle glycogen stores. Leucine, a key branched chain amino acid, is one of the primary nutrients in protein responsible for these benefits. With the introduction of the unique, sustained-release technology, now muscle fueling leucine is released for up to six hours!

NITRO-FACTOR™ - MAXIMIZE MUSCLE BUILDING
The full muscle building potential of a GNC product is based on its total nitrogen content- so the more nitrogen a product has, the stronger it will perform. Nitrogen needs increase during training, and if nitrogen levels are low, your body pulls from muscle stores which can result in catabolism, poor performance and longer recovery. To fuel performance and anabolism, Pro Performance® XR Series™ BCAA Advance XR™ is loaded with 5 grams of nitrogen-boosting ingredients.

Health Notes

Branched-Chain Amino Acids

Branched-Chain Amino Acids
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Athletic Performance and Mental Decline During Exercise at Extreme Temperature
Dose: Refer to label instructions
Some research has shown that branched-chain amino acids help prevent muscle loss at high altitudes, prolong endurance performance in the heat, and improve exercise-induced declines in mental functioning. (more)
Athletic Performance and Post-Exercise Infection at Extreme Temperature
Dose: Refer to label instructions
Some research has shown that branched-chain amino acids may support immune fuction and improve infection at high altitudes and prolong endurance performance in the heat. (more)
Kidney Failure
Dose: Refer to label instructions
(more)
Athletic Performance and Mental Decline During Exercise at Extreme Temperature
Dose: Refer to label instructions

Some research has shown that supplemental branched-chain amino acids (BCAA) (typically 10 to 20 grams per day) do not result in meaningful changes in body composition,1 nor do they improve exercise performance or enhance the effects of physical training.2, 3, 4, 5, 6, 7 However, BCAA supplementation may be useful in special situations, such as preventing muscle loss at high altitudes and prolonging endurance performance in the heat.8, 9 One controlled study gave triathletes 6 grams per day of BCAA for one month before a competition, then 3 grams per day from the day of competition until a week following. Compared with a placebo, BCAA restored depleted glutamine stores and immune factors that occur in elite athletes, and led to a reported one-third fewer symptoms of infection during the period of supplementation.10 Studies by one group of researchers suggest that BCAA supplementation may also improve exercise-induced declines in some aspects of mental functioning.11, 12, 13

Kidney Failure
Dose: Refer to label instructions

The branched-chain amino acids (BCAAs) are leucine, isoleucine, and valine. BCAAs are considered essential amino acids because human beings cannot survive unless these amino acids are present in the diet.

    This stuff works, that's not the problem. it just will not mix! the power doesn't dissolve all the way, instead you get annoying white powder rocks. I finally went crazy and started liquefying it with a blender.

      I have taken several different BCAA's. My favorite so far is cellucor bcaa's. I was in GNC and saw this new product. It is great product but doesn't dissolve well in shaker cup. Great taste but chunks still floating around.
