Solution:

• Glycine is an amino acid, a building block for protein.
• It is not considered an “essential amino acid” because the body can make it from other chemicals.
• A typical diet contains about 2 grams of glycine daily.
• The primary sources are protein-rich foods including meat, fish, dairy, and legumes.
• Your body needs glycine to make important compounds, such as glutathione, creatine and collagen.
• This amino acid may also protect your liver from alcohol-induced damage and improve sleep quality and heart health.
