Amino acids are referred to as the building blocks of protein, and proteins are structural components of body tissues such as muscle, hair, collagen, enzymes, antibodies, and others. Our bodies need 20 different amino acids to function properly, as they play a crucial role in various bodily functions such as muscle growth, tissue repair, energy production, and even immune system support. Let’s explore more how they can be extremely beneficial when added in while working out.

When we exercise, our muscles undergo stress and damage, which stimulates our body to repair and grow stronger muscles; however, for this to happen effectively, our bodies require a sufficient supply of amino acids to fuel the muscle-building process. By ensuring adequate intake of amino acids through diet and supplementation, we can help our body promote better muscle growth, enhance endurance and overall performance, help reduce muscle soreness and fatigue, and experience faster recovery times between workouts. All this will help make workout sessions more enjoyable!

The Best Amino Acids for Workouts

L-arginine is a precursor to nitric oxide which assists in blood vessel dilation, circulation, and proper blood flow. This is great for pre-workout to assist in delivering nutrients to the muscles and improved exercise performance. L-taurine is an essential amino acid that supports healthy tissue and muscle development, making it an excellent pre-workout supplement.

L-glutamine is the most abundant amino in our body. It's beneficial pre- and post-workout for building, rebuilding, and repairing muscle tissue. With extreme exercise, our body depletes levels of glutamine sometimes quicker than it can be replaced. This is very detrimental for athletes, as it limits protein production, and then the body begins to breakdown muscles. Acetyl l-carnitine is also useful pre- and post-workout. It assists lipids and fatty acids into the mitochondria for energy production and can reduce recovery time after intense workouts.

L-lysine can be utilized post-workout. It's an essential amino acid found in high amounts in our muscles and plays an important role in building and maintaining healthy muscle tissue. When it's combined with other vitamins and minerals, it can form other aminos. For example, when it's combined with vitamin C our body converts lysine to carnitine. Glycine is another beneficial post-workout amino acid, as it promotes reduced recovery time following intense exercise.

Incorporating amino acids into our workout routine can provide numerous benefits for muscle growth, recovery, and overall performance. Typically, they are available in a convenient powder or capsule form, and to maximize their benefits during workouts, we should consume them before, during, or immediately after exercising. This will help ensure that our muscles have access to these crucial nutrients when they need them most. By understanding their role in the body and choosing the right types to support your exercise goals, we'll be on our way to building a stronger and healthier version of ourself!
