5 Best Amino Acids for Muscle Growth of 2020

Pre-Workout Supplement Advice

Working out at the gym or at home is obviously the best way to build muscle and endurance. That said, there’s only so much that the body can do and handle in a given time period. You can only push so hard and so far before your body starts to feel the effects.

However, this is where BCAAs come into play, essential branch chain amino acids which can help promote muscle growth, muscle recovery, and more. Today we want to take a look at the 5 best amino acids for muscle growth. Each one is a bit different, but they all have their specific benefits.

What are BCAAs?

BCAAs are the essential amino acids including leucine, isoleucine and valine. They make up about 35% of muscle protein in the human body.

They are known as being essential because your body does not make them on its own and they need to be ingested from outside sources, such as the amino acid or BCAA products we are about to look at.

In most cases they help to increase protein synthesis for muscle building, they can increase stamina/endurance, and they can also aid in faster muscle recovery after workouts.
