How BCAAs Help You Build Lean Muscle

The impact that a good supplement can have on your overall fitness experience cannot be understated, and anyone who has used BCAAs knows this to be true. So how do BCAAs make this happen?

To begin with, BCAA is an acronym for Branched Chain Amino Acid. It describes a unique set of amino acids that account for up to 35% of the pre-formed amino acids that the body requires to function. These amino acids are leucine, isoleucine, and valine. Despite their necessity, the body cannot manufacture them on its own. We are thus left to consume them from external food sources. They naturally occur in small amounts in protein-rich foods like milk, beef, chicken, soy, fish, eggs, baked beans, lentils, cashew nuts, corn, and among so many more. In supplement form the body gets them in more concentrated quantities.


How BCAAs Work

Muscle Growth Stimulation

The reason why most people applaud BCAAs is they essentially stimulate the body to build muscle. This happens through the body’s natural Mammalian Target of Rapamycin, which is referred to as mTOR for short. It sounds like a complex term but what it is essentially is a collection of bodily chemicals that instruct the body to create muscle. They are activated in the abundance of certain types of nutrition, such as BCAAs.

The presence of BCAAs in your diet stimulates the body’s natural mTOR pathway to direct more bodily resources to building muscle. This muscle is nice and lean, which is perfect for burning off fat because it raises your body’s Basal Metabolic Rate, or BMR for short. For everything that you do, all those tasks, your muscles utilize energy and go to work helping to burn off fat. So the leaner muscle in your body, the higher your BMR and thus the more fat you will burn off.


BCAAs For Recovery and Stamina

Building more muscle alone is a great benefit to be enjoyed from having BCAAs in your nutrition supplementation, but that’s not all. It is also great for decreasing muscle soreness and helping you get back to working out faster, as plenty of research suggests.*

BCAAs also make it possible for you to work out for even longer periods of time. The increased presence of BCAAs in your blood stream makes it possible for the muscles to experience less fatigue as a result.*


When Is the Best Time to Consume BCAAs?

Given the time it takes between consumption and actual dissipation into your blood stream, it is advisable to take BCAAs before you begin your workout. It is a great pre-workout supplement that will boost your gains and stamina as you work toward your fitness goals.*
