Amino Acids – The Building Blocks of the Body

Amino acids are the foundation of all proteins in the body and essential for our health. They build and repair tissues, regulate the immune system, form hormones and enzymes, and can provide energy when needed. In total, there are 20 amino acids, nine of which are essential – meaning we must obtain them from food since the body cannot produce them on its own.

What Do Amino Acids Do?

Amino acids combine in different patterns to create proteins, which then perform countless tasks:

Why Are Amino Acids Important?

Amino Acids or Protein Powder?

Protein powder provides complete proteins with both essential and non-essential amino acids. Free amino acids are absorbed faster and can be useful right around training, but they don’t replace whole proteins, which also provide satiety and long-lasting effects.

What Happens if You Don’t Get Enough?

Too few amino acids can lead to muscle loss, weaker immunity, slower recovery, and affect mood and focus. Skin, hair, and nails may also weaken.

The Most Important Amino Acids

Among the non-essential amino acids, glutamine, arginine, tyrosine, and cysteine stand out for their role in immunity, blood flow, stress response, and antioxidant defense.
