Frequently Asked Questions About BCAA Supplements

People tend to have a lot of questions regarding BCAAs, especially considering there are a few common misconceptions, but we're here to clear up some of the more typical queries you may have.

How Do BCAAs Work?

Of the 9 essential amino acids, 3 of them are branched-chain amino acids, or BCAAs, which refer to their chemical structure and are used to improve muscle growth and decrease soreness and fatigue.

They work by essentially stimulating protein synthesis which is vital as your muscles are in a constant state of breaking down and repairing, so the synthesis part is continuously occurring to replace protein lost.


When Should You Take BCAAs?

BCAAs are effective intra and post-workout supplements so they should ideally be consumed either during your gym session or immediately after.

The reason for this is because BCAAs mostly help muscle recovery and alleviating soreness, so you'll likely feel the benefits best if you take them during or after your workouts.

What Do BCAAs Supplements Consist Of?

Although some of the additional ingredients may vary, all BCAA supplements will include Leucine, Isoleucine, and Valine as these are the 3 essential branched-chain amino acids.

Leucine is typically the main component, being the 2 in the 2:1:1 optimum ratio, as it stimulates protein synthesis in skeletal muscle and other tissues.

Other ingredients you may find include Glutamine as an energy source and electrolytes to help regulate your fluid levels.
