BCAAs are amino acids - the building blocks of protein. Our bodies use these amino acids for a multitude of functions. Protein, whether from whole foods or protein supplements, must break down into amino acids to be used by our bodies for specific functions.

You can still take protein supplements with free-form amino acids, such as those found in aminoVITAL. However, BCAAs have some advantages over protein supplements. 

What is Protein?

Protein is a nutrient required in large quantities to maintain body functions. The proteins we consume in food break down into their building blocks called amino acids. The amino acids aid in the growth and repair of tissues, enzymes and hormones creation, immune function support, and a source of energy.

There are 20 amino acids. Of the 20 amino acids necessary for life, nine are considered essential. Our bodies cannot produce essential amino acids, so we must consume them through our diet. Proteins that contain all nine essential amino acids are complete proteins.

What are BCAAs?

BCAAs stands for Branched Chain Amino Acids and account for three out of the nine essential amino acids. BCAA supplements have risen in popularity because they offer many of the same benefits as a whey protein supplement but in a streamlined process. These amino acids are Leucine, Isoleucine, and Valine.


Leucine is the amino acid that triggers muscle protein synthesis. Muscle protein synthesis (MPS) is the process of your body creating new muscle tissue; MPS can also serve as a building block for new muscles. In addition to MPS, Leucine can work as fuel during exercise. Leucine can help to protect the muscles from damage as you work out.


Isoleucine works with Leucine to help boost energy to help you power through your workout and facilitate the repair of muscle tissue damage caused by physical activity.


Valine supports the other amino acid functions. Valine can help guard against muscle damage during exercise. It also helps regulate the immune system, relieves stress, supports cognitive functions, and ensures a steady supply of glucose to power muscle tissue.

BCAA vs. Protein Supplement

Most adults meet their protein needs through a balanced diet. For those such as athletes, the elderly, or those with specific dietary needs, it may not be possible to meet this protein need. BCAA supplements, like aminoVITAL products, provide that opportunity. 

Pure amino acids are absorbed three times quicker than protein, allowing our body to use them right away instead of after digestion. Amino acids supplements may be something to consider for those looking to maximize the benefit of their protein intake.

If you're looking for the highest quality amino acid supplement, look no further than aminoVITAL. The BCAAs and other amino acids used in aminoVITAL products have over 100 years of research backing. The standards used for aminoVITAL are far above nutritional supplements to meet pharmaceutical standards, not just standards set by the FDA. aminoVITAL products are certified vegan, gluten-free, non-GMO, and tested by independent third parties for banned substances.
