More About Amino Acids
What are amino acids?
Amino acids are the basic building blocks of life and are responsible for forming natural proteins within the body. However, there are nine “essential” amino acids the body does not produce on its own. Among these, the "branched-chain" amino acids, or BCAAs, are leucine, isoleucine and valine. Aside from amino acid supplements, BCAAs can be found in protein-rich foods such as eggs, meat and dairy products.
Are amino acids good for muscles?
Yes, amino acids are good for muscle strength, endurance and recovery, especially if you are looking to support your body during and after a workout.
If your goal is to support lean muscle mass, then amino acid supplements are for you. Specifically, the BCAA leucine activates protein synthesis in the body, which is responsible for promoting muscle mass.
Alternatively, if you want to encourage post-workout recovery, amino acid supplements have been shown to relieve occasional discomfort as well as promote healthy energy production after you hit the gym.
Which amino acid supplements should I take?
For supporting muscle recovery, it is important to incorporate a BCAA supplement into your wellness routine. Doing so will enhance exercise performance, promote muscle recovery and support protein synthesis.
However, not all amino acids are for supporting muscle growth and development. The amino acid taurine helps support healthy heart function. Taurine also helps maintain already healthy blood pressure and blood glucose levels.
Additionally, L-arginine is an amino acid that is naturally produced by the body, but some people struggle to get enough through diet. This amino acid helps maintain healthy tissues, bones, and arterial health.
Are there other amino acids for supporting muscle recovery?
If you are looking for additional amino acid support for lean muscle mass, health and recovery after exercise, turn to arginine ornithine. This amino acid powder specifically encourages healthy exercise recovery and lean muscle mass, while also supporting already-healthy blood pressure levels.
