The Science Behind NutraBio BCAA 5000
The essential amino acids leucine, isoleucine, and valine collectively form what is referred to as the branched chain amino acids (BCAAs). These amino acids are essential because they cannot be produced in the body and must be provided though supplementation or diet. BCAAs comprise approximately 30% of the total muscle protein pool and are the primary amino acids oxidized in the muscle during exercise and catabolic stress. For these reasons, athletes supplement with BCAAs for the purpose of increasing muscle mass, reducing muscle damage, blunting fatigue, and increasing energy during exercise.
Hundreds of studies exist on the ergogenic benefits of BCAAs. The majority of them show that BCAAs, whether consumed throughout the day or pre, during, or post-exercise, decrease protein catabolism (breakdown) and support muscle protein synthesis, a physiological process responsible for muscle growth and repair. Furthermore, BCAAs are vitally important to glucose (energy) production, contributing to more than 40% of glucose production during sustained endurance exercises.
A study done in 2009 found that subjects who supplemented with BCAAs while following an 8-week resistance training program had a greater decrease in body fat, an increase in lean mass, and greater strength gains on the bench press and squat compared to the non-BCAA group.
The BCAAs found in NutraBio BCAA 5000 are in the research-backed ratio of 2:1:1 (leucine: isoleucine:valine) and come from plant sources as opposed to animal sources, such as feathers or hair.
L-LEUCINE (2500 mg)
Leucine is one of the essential BCAAs. By itself, it can stimulate muscle protein synthesis, the process responsible for muscle growth and recovery. This is why it is often referred to as the "main" amino acid.
Supplementation with at least 2 grams daily of leucine has been shown to decrease muscle soreness, lessen recovery time between workouts, and increase lean muscle mass.
Howatson et al. (2012) discovered that leucine (combined with isoleucine and valine) administered before muscle damaging resistance exercises reduced indices of muscle damage and accelerated recovery in resistance-trained males.
L-ISOLEUCINE (1250 mg)
Isoleucine, like leucine, is another BCAA that can stimulate muscle protein synthesis but to a lesser extent when not combined with the other BCAAs. However, isoleucine significantly increases glucose uptake and the use of glucose during exercise, leading to greater energy production.
Isoleucine may also play a role in the fat-burning abilities of BCAAs.
Nishimura et al. (2010) found that mice consuming a high-fat diet in conjunction with isoleucine gained less fat mass than mice not receiving isoleucine. This was due to isoleucine's ability to stimulate receptors that inhibit fat storage and increase fat burning.
L-VALINE (1250 mg)
Valine, the third BCAA, promotes muscular endurance and decreases fatigue during exercise.
When exercising, tryptophan is converted to serotonin and signals the brain that the body is fatigued—ultimately leading to a decrease in muscle strength and endurance.
Since valine competes with tryptophan for entry into the brain and prevails, less serotonin gets to the brain, which ultimately leads to stronger muscular contractions, quicker recovery between sets, and prolonged muscular strength and endurance.
