Branch Chain Amino Acids

Amino Acid Tablets - BCAA Tablets- Pro Series Aminos - Branch Chain Amino Acid Tablets. Pro Series Amino Acid Supplements. Pro Aminos for MAXIMUM MUSCLE GROWTH . BCAA Branched chain amino acids are muscle have bodybuilding essentials not just for bodybuilders but also strength & endurance athletes and Rugby Players . Amino acids are the chemical units, or “building blocks” that make up human muscle tissue. Protein quality is measured by the amount of the specific amino’s within it. BCAA - Power Packed Amino Acid Tablets BCAA's (branched chain amino acids) L-leucine, L-isoleucine and L-valine are undoubtedly the single most important group of amino acids for athletes. Around 33% of muscle protein consists of BCAA’s. Even moderate exercise causes levels of BCAA’s to drop rapidly which results in muscle tissue breakdown (catabolism), fatigue, and a drop in testosterone levels. Research shows that athletes who supplemented with BCAA’s during tests experienced increased muscle growth and strength, overall increases in energy, and improved muscle power output. The BEST BCAA Tablets are HARDCORE BIG RED SHARK BCAA's. These full strength tablets ware currently on SPECIAL OFFER!

  Amino acids are essential to the human body. Hard training athletes, Rugby Players and Bodybuilders can especially benefit from supplementing amino acids because they aid in repair, growth, and development of muscle tissue. The body, through assimilation of amino acids, produces over 50,000 proteins and over 15,000 enzymes. Amino acids are not only responsible for the production of all the body's enzymes (including digestive enzymes), but they also play a key role in normalizing moods, concentration, aggression, attention, sleep, and sex drive. After protein is consumed, it is broken down into amino acids. Then, individual amino acids are used to create necessary body proteins and enzymes. Digestive enzymes break down the proteins a person consumes into amino acids.

BCAA - Branch Chain Amino Acids

Take 2-4 Tablets per day. On Training days take 2-3 Tablets 45 minutes before training and 2-3 Tablets within 30 minutes of finishing training.

There are 22 amino acids, without them, all of the metabolic processes necessary to spark and sustain human life would simply not be possible. Long chains of amino acids combine to form up to 55,000 different proteins, and each protein is used to produce the enzymes, neurotransmitters, and hormones that support normal growth and functioning of all bodily organs, including the heart, brain, liver, kidneys, and sex organs.

Amino acids come in two distinct types - essential amino acids and nonessential amino acids. Essential amino acids cannot be manufactured in the body (you get these by eating foods that contain protein), and nonessential amino acids are manufactured within the body by combining two or more essential amino acids. However, adequate amounts of dietary protein are needed to form all 22 amino acids. If you don’t get enough protein your body won’t have the 9 essential amino acids it needs to make up the other 13 nonessential amino acids. This is why we always recommend a full spectrum protein supplement to muscle building bodybuilders.

Today’s modern Western- style diet is composed largely of processed foods which often lack in quality protein, for this reason a good full strength amino acid supplement as listed above is essential for optimum performance and muscle building

What Are Branched-Chain Amino Acids?
The BCAA Are A Group Of Three Essential Amino Acids:

1. Leucine
2. Isoleucine
3. Valine

The BCAA are different from the other 17 amino acids in that they are primarily metabolized in skeletal muscle (Layman, 2003) and metabolized at a much lower rate in the liver (Norton, 2005). The rate limiting enzyme in BCAA catabolism is Branched Chain Keto Acid Dehydrogenase, which is much more active in skeletal muscle than in the liver (Norton, 2005).

Point blank, exercise promotes increased BCAA oxidation (Shirmomura et al., 2004). This increased degradation of BCAA helps maintain energy homeostasis by providing carbon as a direct energy source and glucose homeostasis by providing substrates for the citric-acid cycle and gluconeogenesis.

Amino acids are categorized as glucogenic, ketogenic, or a combination of glucogenic and ketogenic. A glucogenic amino acid when metabolized gives rise to pyruvate or other TCA cycle intermediates that can be used for the production of glucose through gluconeogenesis.

A ketogenic amino acid is metabolized via the fatty acid pathway and gives rise to actyl-CoA, a fatty acid precursor. Leucine is completely ketogenic, valine is completely glucogenic, and isoleucine is both glucogenic and ketogenic. Valine and isoleucine can both be used to produce intermediates for glucose production via gluconeogenesis.

Due to leucine's metabolic properties (discussed below), increasing attention is being given to it and its metabolism. Research has shown plasma leucine levels to decrease during both aerobic and anaerobic exercise (Mero, 1999).

According to Freund and Hanani (2002), "Complete oxidation of leucine in the muscle yields more adenosine triphosphate molecules on a molar basis than complete oxidation of glucose." So leucine can provide skeletal muscle with more ATP than an equal amount of glucose, which is due to leucine being completely ketogenic and metabolized via the fatty acid pathway.

In order to meet the increased demand for BCAA during exercise the body breaks down muscle tissue to supply additional BCAA. By supplying the body exogenous BCAA during exercise, one can  meet the increased demand for BCAA oxidation without breaking down muscle tissue to supply the needed BCAA.

Because BCAA serve as a "fuel" for skeletal muscle, supplementing with additional BCAA during your workout improves your performance without the added calories or insulin spike (which can lead to fat storage) caused by carbohydrates.

Leucine Stimulates Leptin Expression through mTOR activation in Adipocytes

Intake of leucine stimulates expression of the hormone leptin in adipocytes (the primary site of leptin secretion) through activation of the mTOR pathway (Meijer and Dubbelhuis, 2003). Leptin is a very complicated hormone; the gist of it is involved in the regulation of metabolism, body weight, and appetite.

Leptin secretion is linked with body fat levels; higher body fat is associated with higher leptin secretion and lower body fat is associated with lower leptin levels. When you diet and lose fat, the amount of leptin you secrete decreases, which makes your body "crave" food in an attempt to bring your body fat level back up to where the body is comfortable (known as the body fat "set point").

Leucine has the ability to activate leptin expression and will cause the body to think it is "fed" or receiving "adequate" calories, which will keep things running (specifically your metabolism) smoothly.

BCAA and the Glucose-Alanine Cycle

The BCAA's are involved in maintaining glucose homeostasis through the glucose-alanine cycle (see figure 1). The glucose-alanine cycle involves pyruvate (derived from glucose/glycogen) being transaminated in muscle to form alanine, with the BCAA serving as the main nitrogen source (donors) for the synthesis of alanine (Holecek, 2002).

The newly synthesized alanine is released in the blood stream and sent to the liver where it is converted into glucose through gluconeogenesis. This glucose can then be sent from the liver back to the working muscle to be used as fuel. Supplementing with BCAA allowing your body to create glucose to use for fuel without the added calories or insulin spike (which can lead to fat storage) caused by carbohydrates.
