Frequently Asked Questions


What are amino acids?

Amino acids are the building blocks of protein. They are micronized from various foods and used as concentrates in supplements. As a supplement, amino acids cannot aid muscle recovery or muscle growth. But combined with balanced nutrition, the amino acids come with plenty of visible benefits, such as faster recovery.

What are the three types of amino acids?

Essential, conditionally-essential, and non-essential amino acids can be distinguished by category. The first two categories have been described above. However, conditionally-essential amino acids are needed in periods of stress. These amino acids become essential in demanding periods. They include arginine and glutamine.

What does amino acid do for the body?

Amino acids are the building blocks of protein. But they also support body functions and hormone balance. Some amino acids are produced by the body. Others only come from food. By default, nobody needs to use amino acid supplements. Even athletes can train without taking supplements. But their aiding role improves anyone who’s particularly active.

Why do bodybuilders take amino acids?

Bodybuilders mainly take amino acids for muscle growth. The supplement is normally combined with protein-rich meals. Amino acids can also be combined with creatine and whey protein powder.

But bodybuilders also take amino acids to keep muscles that are hard to build. They choose amino acids to maintain muscles when going through weight loss phases and only burn body fat. But amino acids are also used in sports such as running, cycling, and rowing.
