The Amino Acid Advantage—Rapid and Direct Absorption!

When you consume protein from foods such as meat and fish the protein is not directly absorbed in your body. First the protein must be digested and turned into amino acids. To do this the digestive enzymes in your body cleave the proteins' peptide bonds. The amino acids are then absorbed in your gut. This process generally takes three to four hours.

By contrast amino acids do not need to be further digested and your body can absorb them in about 30 minutes.

40% of the Essential Amino Acids that Make up Muscle are BCAAs

The three essential amino acids valine, leucine, and isoleucine are called branched-chain amino acids (BCAAs). Roughly 40% of the essential amino acids that make up muscle are BCAAs.

Supplement with BCAAs to Improve Performance!

During hard or extended exercise our bodies run out of energy sources and begin to break down muscle proteins to use BCAAs for energy. This reduces our muscle and causes muscle damage.

However, supplementing with BCAAs at the right time, such as before or during exercise, gives the body energy to move and reduces muscle breakdown and damage.

This helps you exercise longer. BCAAs are thought to reduce running times in endurance activities such as marathons. BCAAs improve performance in team sports.

BCAAs—Essential Nutrients for Sports

Branched-chain amino acids (BCAAs) comprise the three essential amino acids valine, leucine and isoleucine. BCAAs are of particular interest for sports performance

Nearly 40% of the essential amino acids that make up muscle are BCAAs. BCAAs promote the making of muscle proteins and prevent the breakdown of muscle protein. They are also used by the body for energy during exercise. Through these functions BCAAs are known to help reduce muscle damage and muscle soreness.
BCAAs have been extensively studied by scientists around the world. In the study by MacLean et al., five adult males (average age of 24 years) exercised continuously for 60 minutes with and without taking a supplement of BCAAs at 45 minutes and 20 minutes prior to exercise. The subjects received a BCAAs supplement equivalent to 2.3 grams per 60 kilograms of body weight. The group that took BCAAs clearly displayed less breakdown of muscle protein

These results show that amino acids reduce Muscle Protein Breakdown, which helped to improve performance of exercise.

In the study by Blomstrand et al., 104 male runners (average age of 39 years) with marathon times between 3:00 and 3:30 hours were divided into two groups with one group taking a total of 16 grams of BCAAs in four doses. The group that took BCAAs clearly improved their race times compared with the group not taking BCAAs.

BCAAs Boost Stamina and Recovery!
Supplement with BCAAs before Sports to Reduce Muscle Fatigue
When we push ourselves hard during sports our bodies break down muscle proteins to use BCAAs for energy.
If we supplement with BCAAs before sports our bodies have extra BCAAs available to use for energy.

That way, our bodies break down less of our muscle for energy. This reduces muscle fatigue during exercise, and muscle damage in the medium- and long-term.
